Attributes in this group define ClosedUserGroup options associated with interlockCode. DNA's with the same CUG (interlockCode) can make calls within this group. Various combinations which permit or prevent calls in the same CUG group are defined here.

An entry in the mscFrUniDnaCugCugOptionsTable.

This attribute specifies the CUG type - the CUG is either a national CUG, or an international CUG. International closed user groups are usually established between DTEs for which there is an X.75 Gateway between; whereas national closed user groups are usually established between DTEs for which there is no X.75 Gateway between. (National CUGs cannot normally traverse an X.75 Gateway). If this attribute is set to national, then the CUG is a national CUG, in which case, the dnic should be left at its default value since it is not part of a national CUG. If this attribute is set to international, then the CUG is an international CUG, in which case, the dnic should be set appropriately as part of the CUG interlockCode. Enumeration: 'international': 1, 'national': 0.

This attribute specifies the dnic (Data Network ID Code) of the CUG by which packet networks are identified. This attribute is not applicable if the CUG is a national CUG, as specified by the CUG type attribute. There are usually 1 or 2 dnics assigned per country, for public networks. The U.S. is an exception where each BOC has a dnic. Also, a group of private networks can have its own dnic. dnic value is not an arbitrary number. It is assigned by international agreement and controlled by CCITT.

This attribute specifies the CUG identifier of a national or international CUG call. It is an arbitrary number and it also can be called CUG in some descriptions. Interfaces (DNA's) defined with this number can make calls to DNA's with the same interlockCode.

The attribute 'preferential', if set to yes indicates that this CUG is the SIMPLE CUG (as defined in ITU X.36 [10/96]), in which case it will be used during the call establishment phase if the DTE has not explicitly specified a CUG index in the call request packet. If set to no, then this CUG is not the SIMPLE CUG, but an instance of the SELECTABLE CUG. The attribute 'preferential' is set to no by CAS when a CUG instance is created. If only one CUG instance exists under a DNA, and if this CUG's attributes 'incCalls' and 'outCall' are both set to allowed, then this CUG instance can be changed to a SIMPLE CUG by setting the attribute 'preferential' to yes. If more than one CUG instances exist under a DNA, none of the CUGs can be set by the user as 'preferential'. Essentially, the attribute 'preferential' distinguishes a SIMPLE CUG from a SELECTABLE CUG. In the case of a FRUNI DNA with a single CUG instance, the CUG can be a SIMPLE CUG (preferential = yes) or the only instance of a SELECTABLE CUG (preferential = no). Enumeration: 'yes': 1, 'no': 0.

This attribute, if set to allowed indicates that outgoing calls (from the DTE into the network) can be made using this particular CUG. If set to a value of disallowed, then outgoing calls cannot be made using this CUG - such calls will be cleared by the local DCE. This attribute corresponds to the CCITT 'Outgoing Calls Barred' feature for CUGs in that outgoing calls are barred if this attribute is set to a value of disallowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute, if set to allowed indicates that incoming calls (from the network to the DTE) can be made using this particular CUG. If set to disallowed, then incoming calls cannot be made using this CUG - such calls will be cleared by the local DCE. This attribute corresponds to the CCITT 'Incoming Calls Barred' feature for CUGs in that incoming calls are barred if this attribute is set to a value of disallowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This entry controls the addition and deletion of mscFrUniDnaHgM components.

An entry in the mscFrUniDnaHgMHgAddrAddrTable.

This attribute indicates the Numbering Plan Indicator (NPI) of the DNA. The address may belong to X.121 or E.164 plans. Enumeration: 'e164': 1, 'x121': 0.

This attribute contains digits which form the unique identifier of the customer interface. It can be compared (approximation only) to a telephone number where the phone number identifies a unique telephone set. DNA digits are selected and assigned by network operators.

This group contains the interface parameters between the HuntGroupMember and the hunt group server.

An entry in the mscFrUniDnaHgMIfTable.

This attribute specifies how much availableAggregateCIR can change before an Availability Message Packet (AMP) is sent to the hunt group server informing it of the change. If the value specified is not a multiple of 2048, the value actually used as the threshold will be the next higher multiple of 2048.

This group contains the operational attributes of the HuntGroupMember component.

An entry in the mscFrUniDnaHgMOpTable.

This attribute indicates the maximum available bandwidth for this hunt group member. This value represents the total sum of the sixteen egress bandwidth pools. It is the sum of the sixteen indices of the FrUni Ca egressBandwidthPool attribute multiplied by the link speed.

This attribute indicates the current total available bandwidth reported to the hunt group server in the Availability Message Packet (AMP). This value represents the sum of the sixteen currently available egress bandwidth pools. It is the sum of the sixteen indices of the FrUni Ca egressPoolAvailableBandwidth attribute. It increments when a connection is released. It decrements when a connection is accepted. Both this attribute and the availableDlcis attribute must be non zero for this interface to receive calls on a hunt group.

This attribute indicates the net change in the available aggregate CIR since the last Availability Message Packet (AMP) was sent to the Hunt Group. Once the absolute value of this attribute reaches the availabilityUpdateThreshold an AMP is sent to the hunt group server(s) and the availabilityDelta is re-computed.

This attribute indicates the number of DLCIs available for SVCs on the interface associated with this DNA. If this value reaches 0, an AMP with zero availability is sent to the hunt group server(s). Both this attribute and the availableAggregateCir attribute must be non zero for this DNA to receive calls on the hunt group.

This group contains attributes common to all DNAs. Every DNA used in the network is defined with this group of 2 attributes.

An entry in the mscFrUniDnaAddressTable.

This attribute indicates the Numbering Plan Indicator (NPI) of the DNA that is entered. Address may belong to X.121 or E.164 plans. X.121 is used in packet switched data networks. Enumeration: 'e164': 1, 'x121': 0.

This attribute indicates the customer's unique identifier. It is the equivalent of the telephone number in the telephone network.

This group defines DNA call options for calls made from the interface. These options are not used for calls arriving to the interface represented by this DNA.

An entry in the mscFrUniDnaOutgoingOptionsTable.

This attribute indicates the default priority of outgoing calls from the DTE to the network. It can be overridden by the discardPriority under DLCI Direct Call subcomponent. This option can be also included in X.25 signalling, in such case it will be overruled. Enumeration: 'high': 1, 'normal': 0.

This attribute specifies the default class of path sensitivity to network for all outgoing calls that use this DNA. The chosen default class of path sensitivity applies to all outgoing calls established using this DNA. This attribute, if set to throughput, indicates that the default class is throughput sensitive. If set to delay, then the default class is delay sensitive. The default of outDefaultPathSensitivity is throughput. Enumeration: 'delay': 1, 'throughput': 0.

If this attribute is set to yes in the call request, the called end will use the calling end provisioning data on path sensitivity to override its own provisioning data. The default of outPathSensitivityOverRide is yes. Enumeration: 'yes': 1, 'no': 0.

This attribute specifies the default class of routing for reliability routing for all outgoing calls (from the DTE to the network) using this particular DNA. The chosen default class of routing applies to all outgoing calls established using this DNA, and applies to the packets travelling in both directions on all outgoing calls (local to remote, and remote to local). For incoming calls, the default class of routing is chosen by the calling party (as opposed to DPN, where either end of the call can choose the default routing class). This attribute, if set to a value of normal, indicates that the default class of routing is normal reliability routing. If set to a value of high, then the default class of routing is high reliability routing. High reliability is the standard choice for most DPN and Passport services. It usually indicates that packets are overflowed or retransmitted at various routing levels. Typically high reliability results in duplication and disordering of packets in the network when errors are detected or during link congestion. However, the VC handles the duplication and disordering to ensure that packets are delivered to the DTE properly. For the Frame Relay service, duplication of packets is not desired, in which case, normal reliability may be chosen as the preferred class of routing. Enumeration: 'high': 0, 'normal': 1.

This attribute is an extension of the Closed User Group (CUG) facility, as follows: This attribute, if set to a value of allowed indicates that outgoing calls (from the DTE to the network) to the open (non-CUG) part of the network are permitted. It also permits outgoing calls to DTEs that have Incoming Access capabilities. If set to a value of disallowed, then such calls cannot be made using this DNA. Such calls will be cleared by the local DCE. This attribute corresponds to the CCITT 'Closed User Group with Outgoing Access' feature for DNAs in that outgoing access is granted if this attribute is set to a value of allowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute specifies the default transfer priority for all outgoing calls using this particular DNA. It can be overridden by the transferPriority provisioned in the Dlci DirectCall sub-component. The transfer priority is a preference configured for an application according to its delay-sensitivity requirement. Frames with higher transfer priority are served by the network before the frames with lower priority. The transfer priority standard is defined to have 16 levels from 0 to 15. Each transfer priority n, where n indicates the transfer priority index, contains a default setting for routing class of service (multimedia, delay or throughput) and frame relay egress queue (depending on the number of supported egress queues on the remote end interface) specified by the routingClassOfService and emissionPriority attributes provisioned in the Mod Frs DprsNet Tpm/n component. The default mapping can be altered by a user if required. The default defaultTransferPriority is 0. Enumeration: 'n12': 12, 'n13': 13, 'n10': 10, 'n11': 11, 'n14': 14, 'n15': 15, 'n8': 8, 'n9': 9, 'n0': 0, 'n1': 1, 'n2': 2, 'n3': 3, 'n4': 4, 'n5': 5, 'n6': 6, 'n7': 7.

When this attribute is set to yes in the call request, the called end will use the calling end provisioning data on transfer priority to override its own provisioning data. If it is set no, the called end will use its own provisioning data on transfer priority. This attribute is not applicable for Frame Relay SVCs. For more information about transfer priority, please refer to the previous attribute defaultTransferPriority. The default of transferPriorityOverRide is yes. Enumeration: 'yes': 1, 'no': 0.

This group defines options for incoming calls. These options are used for calls arriving to the interface represented by this DNA. For calls originated from the interface, IncomingOptions attributes are not used.

An entry in the mscFrUniDnaIncomingOptionsTable.

This attribute, if set to a value of allowed specifies that incoming calls (from the network to the DTE) from the open (non-CUG) part of the network are permitted. It also permits incoming calls from DTEs that have outgoing access capabilities. If set to a value of disallowed, such calls cannot be made to this DNA. They will be cleared by the local DCE. This attribute corresponds to the CCITT 'Closed User Group with Incoming Access' feature for DNAs in that incoming access is granted if this attribute is set to a value of allowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This group defines additional all options for not related to direction of the call.

An entry in the mscFrUniDnaCallOptionsTable.

This attribute specifies the accounting class which is reserved for network operations usage. Its value is returned in the accounting record in the local and remote service type attributes. Use of this attribute is decided by network operator. This attribute is returned by the local VC in the accounting record for all calls that are set up using this particular DNA.

This attribute indicates that accounting records are to be collected by the network for the various reasons: billing, test, study, auditing. The last of the parameters, force, indicates that accounting records are to be collected irrespective of other collection reasons. The force option is available for X.75 Gateways only. If none of these reasons are set, then accounting will be suppressed. To set a specific accounting collection reason, the reason is entered and the corresponding bit in the structure is set to a value of 1. To turn off a specific accounting collection reason, the reason is entered preceded with the '~' character, and the corresponding bit in the structure is set to a value of 0. The bit placement for the accounting collection reasons is as follows: Bit 0 - Bill Bit 1 - Test Bit 2 - Study Bit 3 - Audit Bit 4 - Force Description of bits: bill(0) test(1) study(2) audit(3) force(4)

This attribute is an arbitrary number, Data Service Exchange, as entered by the network operator and reported in accounting record. It is converted into an internal 8-bit integer value for use in the accounting record as well as in various X.25 and X.75 Tariff utilities.

This attribute specifies if egress accounting is enabled by the frame relay service. If egress accounting is disabled, only segment counts are collected by the VC. No frame relay counts appear in the accounting records for the frame relay service. If egress accounting is enabled, the accounting records for the frame relay service will contain frame relay specific counts. Enumeration: 'yes': 1, 'no': 0.

This attribute specifies the data path to be used by Virtual Circuits on this interface. If the connection has a DirectCall component then the value can be overridden by the dataPath attribute of the DirectCall component. This value applies to the connection after data transfer state is reached. All the data and control trafic will be sent using this data path. If the provisioned dataPath is not available the connection is not established. The value of the dataPath is signalled by both ends of the connection. If this value is not the same at both ends dprsOnly is used for the duration of the connection. A virtual circuit connection is always established using dprsOnly even if this attribute is provisioned as some other value. dprsOnly - dynamic packet routing system is used dprsMcsOnly - dprs Multi-Service Cut-Through Switching path is used. dprsMcsFirst - dprs Multi-Service Cut-Through Switching path is used if it is available. If it is not avaliable dprsOnly is used. Enumeration: 'dprsMcsOnly': 1, 'dprsMcsFirst': 2, 'dprsOnly': 0.

This group contains attributes defining the framing of data on the link interface.

An entry in the mscFrUniFramerLinkTable.

This attribute determines whether data bits are to be inverted (1 to 0 and 0 to 1) before transmission of frames to the interface. If the value of this attribute is On, the incoming data bits will also be inverted when frames are received from the link before being processed. This option is typically used in hdlc framing mode when inversion is used to guarantee 1's density. Note that aborts (in hdlc and interrupting modes) are corrupted when data is inverted. This attribute may only take its default value for non-MSA cards. Enumeration: 'on': 16, 'off': 0.

This attribute defines the type of CRC used. The CRC value calculated is appended to the end of the frames transmitted to the link. The CRC value is removed from the end of frames received from the link and checked for correctness. NoCrc means that CRC is not used. This attribute may take only its default value for non-MSA cards. Enumeration: 'crc32': 1, 'noCrc': 2, 'crc16': 0.

This attribute defines the number of flags that are inserted between frames sent to the link interface.

This accommodates Frame Relay user equipment that has not implemented any LMI procedures. The remaining attributes of this group are ignored. vendorForum: Local Management Interface procedures from the Vendor Forum specification are supported on this interface. DLCI 1023 is used for the LMI protocol. This value cannot be used if the side attribute is both. ansi: Local Management Interface procedures from the ANSI specification are supported. DLCI 0 is used for the LMI protocol. itu: Local Management Interface procedures from the ITU-T specification are supported. DLCI 0 is used for the LMI protocol. Was previously ccitt. autoConfigure: The interface determines automatically which Local Management Interface procedures to use. This value cannot be used if the side attribute is user. The procedures currently in use can be seen in the operational attribute opProcedures. Enumeration: 'ansi': 2, 'none': 0, 'it': 3, 'autoConfigure': 4, 'vendorForum': 1.

This attribute selects the use of asynchronous PVC status report procedures as specified in ANSI, CCITT, and Vendor Forum. This attribute can be set to on or off. If procedures is set to none, this attribute is ignored. Enumeration: 'on': 1, 'off': 0.

An event is defined as follows: (1) receipt of a STATUS ENQUIRY message; or (2) expiration of timer T392. An error event is (1) nonreceipt of STATUS ENQUIRY in T392 seconds; (2) invalid contents of a LMI message; (3) invalid receive sequence number. This attribute specifies the number of error events which, if they occur within eventCount events, cause a protocol error condition. The condition is cleared after eventCount sequential correct events occur. This attribute corresponds to the nN2 parameter described in the Vendor Forum Specification. It must be less than or equal to eventCount.

This attribute selects the time (in seconds) within which at most five (this is a fixed value and corresponds to maximum message count in VendorForum) STATUS ENQUIRY messages are expected. This attribute applies only when the lmiProcedures is set to vendorForum. messageCountTimer must always be greater than checkPointTimer.

This attribute specifies whether the Frame Relay LMI Active Bit (A-bit) has a bearing on the transfer of user data across this Frame Relay interface for both directions of traffic flow. When this attribute is set to yes, the A-bit status of a user DLCI connection does not affect data transfer. When this attribute is set to no, data received from the local interface will be discarded if an A-bit =0 condition exists towards the local user. Data being sent to the local interface is discarded if an A-bit = 0 condition exists towards the subnet. Enumeration: 'yes': 1, 'no': 0.

This attribute can be set to user, network, or both. When this attribute is set to user, USP LMI procedures are running. When this attribute is set to network, NSP LMI procedures are running. When this attribute is set to both, USPNSP LMI procedures are running. When the value is both, the procedures attribute must not be set to vendorForum. Setting the value to user when the procedures attribute is set to autoConfigure is disallowed semantically. Enumeration: 'both': 2, 'network': 0, 'user': 1.

When this attribute is set to yes, additional Q.933 information elements are included in the LMI Full Status message to facilitate CPE PVC parameter configuring. When set to yes, the Check Prov command fails if the Lmi side is not set to network. When set to yes, Check Prov fails if the number of DLCIs on the FrUni is greater than 300. If the service is not a FrUni this attribute is ignored. Enumeration: 'yes': 1, 'no': 0.

This group contains the three OSI State attributes. The descriptions generically indicate what each state attribute implies about the component. Note that not all the values and state combinations described here are supported by every component which uses this group. For component-specific information and the valid state combinations, refer to NTP 241-7001-150, Passport Operations and Maintenance Guide.

An entry in the mscFrUniLmiStateTable.

This attribute indicates the OSI Administrative State of the component. The value locked indicates that the component is administratively prohibited from providing services for its users. A Lock or Lock - force command has been previously issued for this component. When the value is locked, the value of usageState must be idle. The value shuttingDown indicates that the component is administratively permitted to provide service to its existing users only. A Lock command was issued against the component and it is in the process of shutting down. The value unlocked indicates that the component is administratively permitted to provide services for its users. To enter this state, issue an Unlock command to this component. Enumeration: 'locked': 0, 'shuttingDown': 2, 'unlocked': 1.

This attribute indicates the OSI Operational State of the component. The value enabled indicates that the component is available for operation. Note that if adminState is locked, it would still not be providing service. The value disabled indicates that the component is not available for operation. For example, something is wrong with the component itself, or with another component on which this one depends. If the value is disabled, the usageState must be idle. Enumeration: 'disabled': 0, 'enabled': 1.

This attribute indicates the OSI Usage State of the component. The value idle indicates that the component is not currently in use. The value active indicates that the component is in use and has spare capacity to provide for additional users. The value busy indicates that the component is in use and has no spare operating capacity for additional users at this time. Enumeration: 'active': 1, 'idle': 0, 'busy': 2.

This group provides the protocol status of the Local Management Interface.

An entry in the mscFrUniLmiPsiTable.

This attribute indicates whether the LMI is in an error condition or whether the LMI procedures are behaving normally. When operating with no LMI protocol, this attribute is always set to normalCondition. When operating with LMI procedures, this attribute is set to errorCondition after n392 of the last n393 events are in error. The consequence of an errorCondition is that all DLCIs on this interface will become inactive in both directions. The errorCondition is cleared and a normalCondition is indicated when a sufficient number of events have occurred without error. In ANSI, this occurs when n393 consecutive good events take place. If the procedures attribute is set to autoConfigure, this attribute is set to configuring while adaptive LMI determines which LMI procedures are running on the link. A single LMI error event during auto configuration causes the attribute value to change to errorCondition. If during configuring no LMI message is received, an LMI errorCondition is raised after n392 x t392 seconds. Enumeration: 'normalCondition': 1, 'configuring': 2, 'errorCondition': 0.

The opProcedures attribute indicates the procedures being used for the Local Management Interface. This attribute should be ignored if protocolStatus is not normalCondition. The following procedures are supported: none: Local Management Interface procedures are not running on this interface. This accommodates Frame Relay user equipment that has not implemented any LMI procedures. vendorForum: Local Management Interface procedures from the Vendor Forum specification are running on this interface. DLCI 1023 is used for the LMI protocol. ansi: Local Management Interface procedures from the ANSI specification are running. DLCI 0 is used for the LMI protocol. itu: Local Management Interface procedures from the ITU-T specification are running. DLCI 0 is used for the LMI protocol. Was previously ccitt. unknown: Local Management Interface procedures have yet to be determined by Adaptive LMI. Enumeration: 'ansi': 2, 'none': 0, 'it': 3, 'vendorForum': 1, 'unknown': 4.

This group contains the operational statistics for the Frame Relay Local Management Interface.

This attribute counts the number of Local Management Interface valid full status enquiry messages received from the external user device. When the maximum count is reached it wraps to zero.

This attribute displays the Local Management Interface network side procedure event history in order of occurrence. An event is represented by a single symbol. A '+' symbol indicates a good event. An 'X' symbol indicates a protocol error event. The leftmost event is the most recent to occur. The provisioned eventCount (nN3/ N393) dictates the maximum number of events displayed. A good event is triggered by receipt of a valid status enquiry message. An error event is one of three possibilities, either a nT2/T392 timer expiry, receipt of a status enquiry message with bad sequence numbers, or when lmiProcedures is provisioned to vendorForum and we receive more than nN4 status enquiry messages within the provisioned messageCountTimer (nT3).

This attribute counts the number of Local Management Interface protocol errors. It is the sum of the sequence (sequenceErrors), timeout (pollingVerifTimeouts) and too many status enquiry messages received within the messageCountTimer (nT3) errors. The too many status enquiries error only applies when lmiProcedures is set to vendorForum. When the maximum count is exceeded it wraps to zero.

This attribute counts the number of Local Management Interface frames received with an Information Element identifier that is unknown or unexpected. An unexpected Information Element is not a protocol error. When the maximum count is reached, this counter wraps to zero.

This attribute counts the number of Local Management Interface Status Enquiry message sequence errors. A sequence error is receipt of a Status Enquiry message with a receive sequence number not equal to the last send sequence number. When the maximum count is reached the counter wraps to zero.

This attribute counts the number of Local Management Interface frames received with an unknown or unexpected report type. An unexpected report type is not a protocol error. When the maximum count is reached the counter wraps to zero.

This attribute counts the number of checkPointTImer (t392) timer expiries occurring on the Local Management Interface. When the maximum count is reached the counter wraps to zero.

This attribute counts the number of Local Management Interface keep alive enquiry status messages sent to the external user device for keep alive status. When the maximum count is reached it wraps to zero.

This attribute counts the number of Local Management Interface full status messages sent to the external user device in response to a status enquiry for keep alive or full status. When the maximum count is reached it wraps to zero.

This attribute displays the Local Management Interface user side procedure event history in order of occurrence. An event is represented by a single symbol. A '+' symbol indicates a good event. An 'X' symbol indicates a protocol error event. The left most event is the most recent to occur. The provisioned eventCount (nN3/ N393) dictates the maximum number of events displayed. A good event is triggered by receipt of a valid status message. An error event is either a nT1/T391 timer expiry or receipt of a status message with bad sequence numbers.

This attribute counts the number of Local Management Interface Status message sequence errors. A sequence error is receipt of a Status message with a receive sequence number not equal to the last send sequence number. When the maximum count is reached the counter wraps to zero.

This attribute counts the number of times when no status report or an invalid status report comes from the external network. This attribute is incremented in two cases: i) after a status enquiry is sent out and T391 timer expires without having a status report received. ii) an invalid status report is received. When the maximum count is reached it wraps to zero.

This group contains the provisionable attributes of the Local Management Interface user side procedure.

An entry in the mscFrUniLmiUspParmsTable.

This attribute specifies how frequently the Frame Relay UNI service should initiate a Status Enquiry for a full PVC status report. A polling cycle is a Status Enquiry and Status Report exchange. This attribute is used only if the side attribute is either user or both.

This attribute specifies how frequently the Frame Relay UNI service should initiate a Status Enquiry for link integrity verification. It must be less than checkPointTimer (t392). When the Lmi side is network, this attribute is ignored.

This group defines attributes associated with a direct call. It defines connection in terms of path and call option parameters. This connection can be permanent (PVC), switched (SVC), or switched permanent (SPVC). It can have four facilities: - CCITT Facilities - DTE Facilities - National Facilities - International Facilities The total number of bytes of facilities including the facility codes and all of the facility data from all of the four classes of facilities must not exceed 512 bytes.

An entry in the mscFrUniDlciDcOptionsTable.

This attribute specifies the Numbering Plan Indicator (NPI) of the remoteDna. Enumeration: 'e164': 1, 'x121': 0.

This attribute specifies the Data Network Address (DNA) of the service at the remote end of the DLCI. This is the called (destination) DCE address (DNA) of this PVC.

This attribute specifies the remote DLCI of the PVC connection.

This attribute specifies the type of VC call. If the value is set to permanentMaster, then a permanent connection will be established between two ends. The remote end must be defined as a permanentSlave, permanentBackupSlave, or permanentSlaveWithBackup. The connection cannot be established if the remote end is defined as anything else. The end defined as permanentMaster always initiates the calls. It attempts to call once per minute. If the value is set to permanentSlave then a permanent connection will be established between two ends. The remote end must be defined as a permanentMaster. The connection cannot be established if the remote end is defined as anything else. The permanentSlave end attempts to call once per minute. If the value is set to permanentSlaveWithBackup then a permanent connection will be established between the two ends. The remote end must be defined as a permanentMaster. The connection cannot be established if the remote interface is defined as anything else. The permanentSlaveWithBackup attempts to call once per minute. When type is set to permanentSlaveWithBackup, the connection is cleared if the interface becomes unavailable. This enables a retry of the connection which can be redirected to the permanentBackupSlave. If the value is set to permanentBackupSlave then a permanent connection is established between the two ends only if the permanentMaster end is disconnected from the permanentSlaveWithBackup end and a backup call is established by the call redirection system. If the permanentSlaveWithBackup interface becomes available again, the permanentBackupSlave end is disconnected and the permanentSlaveWithBackup end is reconnected to the permanentMaster end. The permanentBackupSlave end does not try to establish a call. If the value is set to spvcMaster, then a permanent connection is established between two ends, with resiliency at the NNI), if the connection transits across two or more networks. The remote end, which may be in the same network, or an external network that is reachable via Frame Relay NNIs, must be defined as either a spvcSlave, spvcBackupSlave or spvcSlaveWithBackup. The connection cannot be established if the remote end is defined as anything else. The end defined as spvcMaster always initiates the call. It attempts to call once per minute. The call is attempted by the spvcMaster and accepted by the remote end only if all of the following conditions are satisfied, at both ends: 1. The physical layer must be operational. 2. The LMI procedures must be in normalCondition (that is, no service affecting condition). 3. If the LMI side attribute is provisioned to both, the A-bit received from the interface must be Active. If the LMI side attribute is not provisioned to both, this condition does not apply. After a call is cleared, the spvcMaster end attempts to retry the call according to the rule for the clear cause. If the call is cleared or rejected due to the failure of one of the three conditions indicated above, or due to unavailability of resources along any point in the connection path, the call will be retried after 60 seconds. For all other causes, such as loss of service at an NNI, the call will be retried immediately. If the value is set to spvcSlave then an SPVC connection is established between two ends. The remote end must be defined as an spvcMaster. The connection cannot be established if the remote end is defined as anything else. The spvcSlave end does not attempt to call. If the value is set to spvcSlaveWithBackup then a SPVC connection is established between the two ends. The remote end must be defined as an spvcMaster. The connection cannot be established if the remote interface end is defined as anything else. Unlike a permanentSlaveWithBackup end, the spvcSlaveWithBackup end does not attempt to call. If the value is set to spvcSlaveWithBackup, the connection is cleared if the interface becomes unavailable. This enables a retry of the connection by the spvcMaster end, which may be redirected to an end that is set to spvcBackupSlave. If the value is set to spvcBackupSlave then an SPVC connection is established between the two ends only if the spvcMaster end is disconnected from the spvcSlaveWithBackup end, and a backup call is redirected by the call redirection system. Unlike the PVC connection, if the spvcSlaveWithBackup interface becomes available again, the spvcBackupSlave end is not disconnected and the spvcSlaveWithBackup end is not reconnected to the spvcMaster end. Neither the spvcBackupSlave nor the spvcSlaveWithBackup ends try to establish an SPVC call. Enumeration: 'permanentSlaveWithBackup': 4, 'spvcSlaveWithBackup': 8, 'spvcSlave': 6, 'permanentBackupSlave': 3, 'permanentMaster': 1, 'spvcMaster': 5, 'permanentSlave': 2, 'spvcBackupSlave': 7.

This attribute specifies the transfer priority to the local network for the outgoing calls using this particular DLCI. It overrides the defaultTransferPriority provisioned in its associated Dna component. The transfer priority is a preference configured for an application according to its delay-sensitivity requirement. Frames with higher transfer priority are served by the network before the frames with lower priority. The transfer priority standard is defined to have 16 levels from 0 to 15. Each transfer priority n, where n is the transfer priority index, has a default setting for routing class of service (multimedia, delay, or throughput) and Frame Relay egress queue (depending on the number of supported egress queues on the remote end interface). These settings are specified by the routingClassOfService and emissionPriority attributes provisioned under the Mod Frs DprsNet Tpm/n component. Specifying useDnaDefTP means using the value given by defaultTransferPriority in the associated Dna for this DLCI. Enumeration: 'n12': 12, 'n13': 13, 'n10': 10, 'n11': 11, 'n14': 14, 'n15': 15, 'useDnaDefTP': 255, 'n8': 8, 'n9': 9, 'n0': 0, 'n1': 1, 'n2': 2, 'n3': 3, 'n4': 4, 'n5': 5, 'n6': 6, 'n7': 7.

This attribute specifies the discard priority for outgoing call using this DLCI. The discard priority has three provisioning values: normal, high, and useDnaDefPriority. Under congestion conditions, traffic with normal priority is discarded before traffic with high priority. The Dna default value (provisioned by outDefaultPriority) is taken if this attribute is set to the value useDnaDefPriority. Enumeration: 'high': 1, 'useDnaDefPriority': 3, 'normal': 0.

This attribute specifies whether the discardPriority applies to DE frames for this DLCI. When set to determinedByDiscardPriority, traffic with DE bit set will be discarded according to the setting of the discardPriority. When set to lowest, all traffic with DE bit set is treated the same and is sent to the subnet at the lowest discard priority. Enumeration: 'lowest': 0, 'determinedByDiscardPriority': 1.

This attribute specifies the data path to be used by Virtual Circuits on this interface. The value of the dataPath attribute in the Dna component is overridden by this attribute if the value is not useDnaValue. This value applies to the connection after data transfer state is reached. All the data and control traffic will be sent using this data path. If the provisioned dataPath is not available the connection is not established. The value of the dataPath is signalled by both ends of the connection. If this value is not the same at both ends dprsOnly is used for the duration of the connection. A virtual circuit connection is always established using dprsOnly even if this attribute is provisioned as some other value. dprsOnly - The dynamic packet routing system is used. dprsMcsOnly - The DPRS Multi-Service Cut-Through Switching path is used. dprsMcsFirst - The DPRS Multi-Service Cut-Through Switching path is used if it is available. If it is not available, dprsOnly is used. useDnaValue - The routing system used is based on the value provisioned in the Dna component. Enumeration: 'useDnaValue': 3, 'dprsMcsOnly': 1, 'dprsMcsFirst': 2, 'dprsOnly': 0.

This attribute specifies the CUG index which is to be signalled in PVC and SPVC call requests to the remote end. The type of CUG signalling is defined in attribute cugType in this component.

This attribute specifies the type of CUG signalling to be used in PVC and SPVC call requests. Index of CUG to be used is defined in attribute cugIndex in this component. Possible values are: cug - signal CUG cugOa - signal CUG with outgoing access doNotSignal - no CUG in call request Enumeration: 'cug': 3, 'doNotSignal': 0, 'cugOa': 9.

This attribute specifies whether an IP TOS value is mapped to an FR QOS. The mapping used is provisioned in the Mod Frs IpCosToFrQos component. When this attribute is set to yes, at Frame Relay egress, the IP TOS byte in each frame is checked. The TOS value determines the egress emission queue and the discard priority for that frame. When this attribute is set to no, FR QOS is determined by the provisioned discard priority and transfer priority. Enumeration: 'yes': 1, 'no': 0.

This is the i'th National facility required for this direct call. Within the provisioning system, the user specifies the facility code along with the facility parameters. The facility is represented internally as a hexadecimal string following the X.25 ITU-T representation for facility data. Two explicit attributes discardPriority and pathSensitivity are created to replace H.01 and H.30 in the group VcsDirectCallOptionsProv of this file. The migrate escape here (DcComponent::migrateFaxEscape) propagates the old provisioning data under H.01 and H.30 into discardPriority and transferPriority. The rule of the above propagation are: 0 in H.01 is equivalent to discardPriority 0; 1 in H.01 is equivalent to discardPriority 1. And 0 in H.30 is equivalent to transferPriority throughput; 1 in H.30 is equivalent to pathSensitivity delay. Please refer to discardPriority and pathSensitivity for more information on how to use them.

If the connection is using dprsMcsFirst data path, the string dprsMcsFirst is displayed.

This group defines display of interval data collected by Vc. Data in this group is variable and may depend on time when this display command is issued.

An entry in the mscFrUniDlciVcIntdTable.

This attribute is obsolete. It is replaced by the callReferenceNumber attribute to display the call reference number in decimal. The SNMP reference for the callReferenceNumber attribute is callReferenceNumberDecimal.

This attribute displays the elapsed time representing the period of this interval data. It is elapsed time in 0.1 second increments since Vc started.

This attribute displays the number of segments received at the time command was issued. This is the segment received count maintained by accounting at each end of the Vc. This counter is updated only when the packet cannot be successfully delivered out of the sink Vc and to the sink AP Conditions in which packets may be discarded by the sink Vc include: missing packets due to subnet discards, segmentation protocol violations due to subnet discard, duplicated and out-of-ranged packets and packets that arrive while Vc is in path recovery state.

This attribute displays the number of segments sent at the time command was issued. This is the segment sent count maintained by accounting at the source Vc. Vc only counts packets that Vc thinks can be delivered successfully into the subnet. In reality, these packets may be dropped by trunking, for instance. This counter is not updated when splitting fails, when Vc is in a path recovery state, when packet forwarding fails to forward this packet and when subsequent packets have to be discarded as we want to minimize the chance of out-of-sequence and do not intentionally send out-of- sequenced packets into the subnet.

This attribute displays the start time of this interval period. If Vc spans 12 hour time or time of day change startTime reflects new time as recorded at 12 hour periods or time of day changes.

This attribute displays the call reference number which is a unique number generated by the switch.The same Call Reference Number is stored in the interval data (accounting record) at both ends of the call. It can be used as one of the attributes in matching duplicate records generated at each end of the call.

This group defines Frame Relay attributes collected by Frame Relay Vc. The purpose of Vc attributes is to aid end users and verification people to understand the Vc internal behavior. This is particularly useful when the network has experienced abnormality and we want to isolate problems and pinpoint trouble spots. Attributes are collected on a per Vc basis. Until a need is identified, statistics are not collected at a processor level. Each attribute is stored in a 32 bit field and is initialized to zero when a Vc enters into the data transfer state. When a PVC is disconnected and then connected again, the attributes will be reset. Attributes cannot be reset through other methods. Frame Relay Vc uses a best effort data packet delivery protocol and a different packet segmentation and combination methods from the General Vc. The Frame Relay Vc uses the same call setup and control mechanism (e.g. the support of non-flow control data packets) as in a General Vc. Most General Vc statistics and internal variables are used in a Frame Relay Vc and are displayed by software developers

An entry in the mscFrUniDlciVcFrdTable.

This attribute displays the number of frames from link discarded due to lack of resources. It keeps track of the number of frames from link that have to be discarded. The discard reasons include insufficient memory for splitting the frame into smaller subnet packet size.

This attribute displays the number of discarded packets that can not be forwarded into the subnet because of subnet congestion. Number of frames from link discarded due to failure in forwarding a packet from Vc into the subnet.- This attribute is increased when packet forwarding fails to forward a packet into the subnet. If a frame is split into multiple subnet packets and a partial packet has to be discarded, all subsequent partial packets that have not yet been delivered to the subnet will be discarded as well.

This attribute records the number of frames from link discarded when the Vc tries to recover from internal path failure.

This attribute displays the number of frames from subnet discarded due to out of sequence range for arriving too late.

This attribute records the number of subnet packets discarded at the sink Vc due to the Vc segmentation and combination protocol error. Usually, this occurs when the subnet discards packets and thus this statistics can be used to guest the number of subnet packets that are not delivered to the Vc. It cannot be used as an actual measure because some subnet packets may have been delivered to Vc but have to be discarded because these are partial packets to a frame in which some other partial packets have not been properly delivered to Vc

This attribute displays the number of subnet packets discarded due to duplication. Although packets are not retransmitted by the Frame Relay Vc, it is possible for the subnet to retransmit packets. When packets are out-of-sequenced and copies of the same packets arrive, then this attribute is increased.

This attribute displays the number of subnet packets discarded when data transfer is suspended in Vc recovery.

This attribute displays the number of lost frame timer expiries. When this count is excessive, the network is very congested and packets have been discarded in the subnet.

This attribute displays the number times that the out of sequence byte threshold is exceeded. When the threshold is exceeded, this condition is treated as if the loss frame timer has expired and all frames queued at the sink Vc are delivered to the AP. We need to keep this count to examine if the threshold is engineered properly. This should be used in conjunction with the peak value of out-of- sequenced queue and the number of times the loss frame timer has expired. This count should be relatively small when compared with loss frame timer expiry count.

This attribute displays the frame relay peak packet count of the out of sequence queue. This attribute records the maximum queue length of the out-of-sequenced queue. The counter can be used to deduce the message buffer requirement on a Vc.

This attribute displays the frame relay peak size of the sequence packet queue. The subnet may deliver packets out-of- sequenced. These packets are then queued in an out-of-sequenced queue, waiting for a packet with the expected sequence number to come. When that packet arrives, this attribute records the maximum number of packets that were out-of-sequenced, but now have become in-sequenced. The statistics is used to measure expected queue size due to normal subnet packet disorder (not due to subnet packet discard). Current implementation also uses this statistics to set a maximum size for the out-of-sequenced queue.

This attribute displays the Vc internal packet's send sequence number. Note that a 'packet' in this context, may be either a user data packet, or an OAM frame.

This attribute displays the number of packets which have retransmission time-outs. When this count is excessive, the network is very congested and packets have been discarded in the subnet.

This attribute displays the peak size of retransmission queue. This attribute is used as an indicator of the acknowledgment behavior across the subnet. Records the largest body of unacknowledged packets.

This attribute displays the number of successful Vc recovery attempts.

This attribute displays the number times that the out of sequence packet threshold is exceeded. When the threshold is exceeded, this condition is treated as if the loss frame timer has expired and all frames queued at the sink Vc are delivered to the AP. We need to keep this count to examine if the threshold is engineered properly. This should be used in conjunction with the peak value of out-of- sequenced queue and the number of times the loss frame timer has expired. This count should be relatively small when compared with loss frame timer expiry count.

This attribute displays the frame relay peak byte count of the out of sequence queue. This attribute records the maximum queue length of the out-of-sequenced queue. The counter can be used to deduce the message buffer requirement on a Vc.

This attribute displays the data path used by the connection. Data path is provisioned in Dna and DirectCall components. If the connection is using dprsOnly data path, this attribute is empty. If the connection is using dprsMcsOnly or dprsMcsFirst data path, this attribute displays component name of the dprsMcsEndPoint.

This group contains the provisionable attributes for the Data Link Connection Identifier. These attributes reflect the service parameters specific to this instance of DLCI. The congestion control attributes in this group are defined in T1.606 Addendum 1.

An entry in the mscFrUniDlciSpParmsTable.

This attribute specifies the maximum number of octets which may be included in the information field. The frame relay header and CRC octets are not included in this definition. This attribute corresponds to the dN1 parameter described in the Vendor Forum Specification.

This attribute specifies whether rate enforcement is in effect for this user Data Link Connection on this Frame Relay interface. Turning on rate enforcement means that CIR and DE=1 traffic will be measured and enforced. Turning off rate enforcement means that all frames from the user will be accepted and no modifications to the frame with respect to the DE bit will be made. Enumeration: 'on': 1, 'off': 0.

This attribute specifies the committed information rate (CIR) in bits per second (bit/s). When rateEnforcement is set to on, cir is the rate at which the network agrees to transfer information under normal conditions. This rate is measured over a measurement interval (t) that is determined internally based on CIR and the committed burst size (Bc). An exception to this occurs when CIR is provisioned to be zero, in which case the measurement interval (t) must be provisioned explicitly. This attribute is ignored when rateEnforcement is off. If rateEnforcement is on and this attribute is 0, Bc must also be 0.

This attribute specifies the committed burst size (Bc) in bits. bc is the amount of data that a network agrees to transfer under normal conditions over a measurement interval (t). Data marked DE=1 is not accounted for in Bc. This attribute is ignored when rateEnforcement is off. If rateEnforcement is on and this attribute is 0, cir must also be 0.

This attribute specifies the excess burst size (Be) in bits. Be is the amount of uncommitted data that the network will attempt to deliver over measurement interval T. Data marked DE=1 by the user or by the network is accounted for here. CIR, Bc, and Be cannot all be zero when rateEnforcement is on.

When cir and bc are zero and rateEnforcement is on, this attribute must be provisioned to specify the time interval (in milliseconds) over which rates and burst sizes are measured. When cir and bc are non-zero, the time interval is internally calculated and is not shown. In that situation, this field is ignored, and is not representative of the time interval. This attribute is ignored when rateEnforcement is off, or when cir and bc are non-zero. If rateEnforcement is on and both cir and bc are zero, this field must be non-zero.

This attribute specifies whether rate adaptation is in effect for this user Data Link Connection on this Frame Relay interface. Rate adaptation is a feature that, in periods of congestion, adapts the rate at which the user is allowed to send data into the network to that which the network is able to handle at that time. This pro-active measure of handling congestion optimizes network resources by causing the ingress to discard frames that would otherwise be discarded in the network. If this attribute is set to on, then, at the onset of congestion, the excess information rate (EIR) is reduced to a very low rate. If congestion persists, then the allowed CIR is reduced geometrically by 25% of the current value at that time. The minimum to which CIR can be reduced is 1/16th (6.25%) of the provisioned value. As congestion alleviates, CIR is increased linearly by 6.25% of the provisioned value specified in committedInformationRate. If set to eirOnly, then rate adaptation will only apply to the excess information rate (EIR). At the onset of congestion, the allowed EIR is reduced by 25% of its provisioned value. If congestion persists, EIR is reduced geometrically by 25% of the current value at that time. As congestion alleviates, EIR is gradually increased linearly by 6.25% of the provisioned EIR. If set to cirProportionate, then rate adaptation will also only apply to the excess information rate (EIR). At the onset of congestion the initial allowed EIR is set to a multiple of the provisioned CIR. If congestion persists, the allowed EIR is reduced geometrically by 25% of the current value at that time. As congestion alleviates, EIR is gradually increased linearly by 6.25% of the provisioned EIR. Note that the allowed EIR may be set higher than the provisioned EIR, since it is calculated initially using another parameter, the provisioned CIR. If the allowed EIR at the moment is higher than the provisioned EIR, then the provisioned EIR is used instead. This attribute can only be set to on eirOnly or cirProportionate if rateEnforcement is turned on. Enumeration: 'cirProportionate': 3, 'on': 1, 'off': 0, 'eirOnly': 2.

This attribute specifies whether accounting data collection and record generation is turned on at this DLCI. For accounting data collection and record generation to be turned on, the accountingOn bit and at least one of the accountCollection bits in the DataNetworkAddress component must be set to on. Enumeration: 'on': 1, 'off': 0.

This attribute specifies the sensitivity of the rate adaptation system. A higher number indicates a higher sensitivity and therefore a quicker reaction time to network conditions. A quicker reaction time allows the network to discard frames at the access and protect network resources, but can lead to false alarms and a greater fluctuation of the allowed rate. A higher setting therefore tends to favour the protection of the network over the allowed throughput of the user. A lower number indicates a lower sensitivity and therefore a slower reaction to network conditions. A slower reaction time results in a greater amount of user traffic allowed into the network, but can lead to a waste of network bandwidth since the traffic may be discarded at the congested resource. A lower setting therefore tends to favour the allowed throughput of the user over the protection of the network. This attribute is applicable for adapting EIR when rateAdaptation is eirOnly or cirProportionate, or CIR when rateAdaptation is on. This attribute is ignored if rateAdaptation is turned off.

This attribute specifies whether internal Backward Congestion Indication (BCI) bits will report congestion external to the Passport network, as communicated through incoming BECN bits. If updateBCI is set to on, then BCI bits for incoming frames will be set if the BECN on the frame is set. If updatBCI is set to off, then incoming BECN bits will have no effect. Setting updateBCI on for a DLCI means that the remote end of the DLCI, which is specified by the remotedna and remotedlci attributes of the dc component of the dlci, may perform Rate Adaptation using the flow of incoming BECN bits, in addition to internal Passport congestion management systems. If the rateAdaptation attribute of the remote dlci is provisioned as eirOnly, cirProportionate, or on, then congestion from another network connected to a Passport network may trigger dynamic congestion management. If the rateAdaptation attribute of the remote dlci is provisioned to off, then the setting of updateBCI attribute here will have no effect.. Enumeration: 'on': 1, 'off': 0.

In the description that follows, 'local' refers to the user who has initiated the SETUP request, and 'remote' refers to the user to whom the local user wishes to connect. State description: In the null state, the network has neither received nor sent call setup requests for this DLCI. In the callInitiated state, the network has received a SETUP message from the local user. In the outgoingCallProceeding state, the network has sent a CALL PROCEEDING message to the local user in response to the SETUP message. In the callPresent state, the network has sent a SETUP message to the remote user. In the incomingCallProceeding state, the network has received a CALL PROCEEDING message from the remote user in response to a SETUP message. In the active state, either the network has sent a CONNECT message to the local user, or the network has received a CONNECT from the remote user. In the disconnectRequest state, the network has received a DISCONNECT message from the local user. In the disconnectIndication state, the network has sent a DISCONNECT to the local user. In the releaseRequest state, the network has sent out a RELEASE message to the local user.

This attribute indicates the maximum number of octets which may be included in the information field. The frame relay header and CRC octets are not included in this definition. This attribute corresponds to the dN1 parameter described in the Vendor Forum Specification.

This attribute is obsolete. It provided the information which is now represented by the provisionable attribute rateEnforcement under the ServiceParameters component. Enumeration: 'on': 1, 'off': 0.

This attribute indicates the committed information rate (CIR) in bits per second (bit/s). When rateEnforcement is set to on, cir is the rate at which the network agrees to transfer information under normal conditions. This rate is measured over a measurement interval (t) that is determined internally based on CIR and the committed burst size (Bc). An exception to this occurs when CIR is provisioned to be zero, in which case the measurement interval (t) must be provisioned explicitly. This attribute should be ignored when rateEnforcement is off.

This attribute indicates the committed burst size (Bc) in bits. bc is the amount of data that a network agrees to transfer under normal conditions over a measurement interval (t). Data marked DE=1 is not accounted for in Bc. This attribute should be ignored when rateEnforcement is off.

This attribute indicates the excess burst size (Be) in bits. Be is the amount of uncommitted data that the network will attempt to deliver over measurement interval T. Data marked DE=1 by the user or by the network is accounted for here. This attribute should be ignored when rateEnforcement is off.

Enumeration: 'on': 1, 'off': 0.

This attribute indicates the emission priority of frames sent to the interface. A larger value denotes a higher priority.

This attribute indicates the priority at which data is transferred to the network. The transfer priority is a preference configured for an application according to its delay-sensitivity requirement. Frames with higher transfer priority are served by the network before the frames with lower priority. The transfer priority standard is defined to have 16 indices from 0 to 15. Each transfer priority n, where n specifies the transfer priority index, contains a default setting for routing class of service (multimedia, delay, or throughput) and frame relay egress queue (depending on the number of supported egress queues on the remote end interface) specified by the routingClassOfService and emissionPriority attributes provisioned in the Mod Frs DprsNet Tpm/n component. The default mapping can be altered by a user if required.

This attribute is used to limit the amount of guaranteed SVC throughput allowed into the network at this interface. This attribute is obsoleted, during the migration, the value of this attribute will be transfered to maximumAggregateSvcCirNormalQ or maximumAggregateSvcCirHighQ depending on the value of the attribute outDefaultPathSensitivity under DNA component.

This attribute specifies the maximum aggregate user to network direction EIR allowed for SVCs on the interface. It is provisioned as a percentage of the access link speed. This attribute is ignored if unlimitedAggregateEir, another attribute under the same group, is set to yes.

This attribute is obsoleted, during the migration, the value of this attribute will be transfered to maximumAggregateSvcEirNormalQ or maximumAggregateSvcEirHighQ depending on the value of the attribute outDefaultPathSensitivity under DNA component.

This attribute specifies the maximum number of octets that may be included in the information field of the user DLCI of any switched connections using this interface. Its value must not be smaller than the value of defaultMaximumFrameSize.

This attribute specifies the default maximum number of octets that may be included in the information field of the user DLCI assigned for any switched connections using this interface. This value is used during call parameter negotiation for switched calls on this interface when the maximum frame size is not specified in the user's SETUP message. The value of this attribute must not exceed the value of the maximumFrameSize attribute.

This attribute specifies the default user to network direction Be. This value is used during call parameter negotiation for switched calls on this interface when the Be is not specified in the user's SETUP message.

This attribute specifies whether the network will enforce aggregate EIR during SVC call establishment. The network keeps track of the sum of user to network EIRs for all the SVC DLCIs at this interface. If this attribute is set to no, then the requested EIR for each new SVC call will be adjusted if the resulting aggregate EIR exceeds the value contained in one of the following attributes (depending on the requested Transfer Priority): maximumAggregateSvcEirNormalQ, maximumAggregateSvcEirHighQ or maximumAggregateSvcEirInterruptQ. This may lead to a rejection of the call setup. If this value is set to yes, then no checks will take place. Enumeration: 'yes': 1, 'no': 0.

This attribute specifies whether rate enforcement is in effect for SVCs on this interface. Enumeration: 'on': 1, 'off': 0.

This attribute specifies whether closed-loop rate adaptation is in effect for SVCs on this interface. Rate adaptation is a feature that, in periods of congestion, adapts the rate at which the user is allowed to send data into the network to that which the network is able to handle at that time. This proactive measure of handling congestion optimizes network resources by causing the ingress to discard frames that would otherwise be discarded in the network. If this attribute is set to on, then, at the onset of congestion, the excess information rate (EIR) is reduced to a very low rate. If congestion persists, then the allowed CIR is reduced geometrically by 25% of the current value at that time. The minimum to which CIR can be reduced is 1/16th (6.25%) of the provisioned value. As congestion alleviates, CIR is increased linearly by 6.25% of the provisioned value specified in committedInformationRate. If set to eirOnly, then rate adaptation will only apply to the excess information rate (EIR). At the onset of congestion, the allowed EIR is reduced by 25% of its provisioned value. If congestion persists, EIR is reduced geometrically by 25% of the current value at that time. As congestion alleviates, EIR is gradually increased linearly by 6.25% of the provisioned EIR. If set to cirProportionate, then rate adaptation will also only apply to the excess information rate (EIR). At the onset of congestion the initial allowed EIR is set to a multiple of the provisioned CIR. If congestion persists, the allowed EIR is reduced geometrically by 25% of the current value at that time. As congestion alleviates, EIR is gradually increased linearly by 6.25% of the provisioned EIR. Note that the allowed EIR may be set higher than the provisioned EIR, since it is calculated initially using another parameter, the provisioned CIR. If the allowed EIR at the moment is higher than the provisioned EIR, then the provisioned EIR is used instead. This attribute can only be set to on or eirOnly if rateEnforcement is set to on. Enumeration: 'cirProportionate': 3, 'on': 1, 'off': 0, 'eirOnly': 2.

This attribute specifies the maximum aggregate user to network direction CIR allowed for SVCs on the interface. It is provisioned as a percentage of the access link speed.

This attribute specifies the maximum aggregate user to network direction EIR allowed for SVCs on the interface. It is provisioned as a percentage of the access link speed. This attribute is ignored if unlimitedAggregateEir, another attribute under the same group, is set to yes. This attribute is used to limit, at this interface, the amount of excess SVC throughput allowed into the network through the high priority queue.

This attribute specifies the maximum aggregate user to network direction EIR allowed for SVCs on the interface. It is provisioned as a percentage of the access link speed. This attribute is ignored if unlimitedAggregateEir, another attribute under the same group, is set to yes. This attribute is used to limit, at this interface, the amount of excess SVC throughput allowed into the network through the interrupting queue.

The x213IeHandling attribute specifies how Frame Relay handles the X.213 Priority IE when it is in the FRF.4 setup message. When the attribute is set to notSupported, the X.213 Priority IE will not be recognized in the setup message. A FRF.4 status message will be sent to the calling DTE, with the indication that an unrecognized IE was encountered. The call setup then proceeds as normal, and the X.213 Priority IE does not appear in the setup message at the called end. When the attribute is set to proprietary, and the X.213 Priority IE is present in the FRF.4 setup message, it will be recognized. If there is no Frame Transfer Priority IE in the setup message, the first data byte of the X.213 Priority IE is used to select the transfer and discard priority values for the connection and the X.213 Priority IE is signaled to the called end in the setup message. If the Frame Transfer Priority IE is present in the FRF.4 setup message, its value is used to select the transfer priority, the discard priority is taken from the FRUNI Dna component, and the X.213 Priority IE is ignored. Refer to the related Application Note for further details before setting the attribute value to proprietary. Enumeration: 'notSupported': 0, 'proprietary': 1.

This attribute specifies the sensitivity of the rate adaptation system for all switched connections on this interface. A higher number indicates a higher sensitivity and therefore a quicker reaction time to network conditions. A quicker reaction time allows the network to discard frames at the access and protect network resources, but can lead to false alarms and a greater fluctuation of the allowed rate. A higher setting therefore tends to favor the protection of the network over the allowed throughput of the user. A lower number indicates a lower sensitivity and therefore a slower reaction to network conditions. A slower reaction time results in a greater amount of user traffic allowed into the network, but can lead to a waste of network bandwidth since the traffic may be discarded at the congested resource. A lower setting therefore tends to favour the allowed throughput of the user over the protection of the network. This attribute is applicable for adapting EIR when rateAdaptation is eirOnly or cirProportionate, or CIR when rateAdaptation is on. This attribute is ignored if rateAdaptation is off.

This attribute specifies whether internal Backward Congestion Indication (BCI) bits will report congestion external to the Passport network, as communicated through incoming BECN bits. If updateBCI is set to on, then BCI bits for incoming frames will be set if the BECN on the frame is set. If updateBCI is set to off, then incoming BECN bits has no effect. Setting updateBCI on for a DLCI means that the remote end of the DLCI, which is specified by the remoteDna and remoteDlci attributes of the Dc component of the Dlci, may perform Rate Adaptation using the flow of incoming BECN bits, in addition to internal Passport congestion management systems. If the rateAdaptation attribute of the remote DLCI is provisioned as eirOnly, cirProportionate, or on, then congestion from another network connected to a Passport network may trigger dynamic congestion management. If there is no rate adaptation at the other end, then the setting of updateBCI attribute here will have no effect. Enumeration: 'on': 1, 'off': 0.

This attribute specifies whether Passport needs to check the location of Cause IE in a Release or a Disc message issued by local DTE. If this bit is set to on, then Passport will check the location of Cause IE issued by the local DTE and overwrite it by 'user'. If it is set to off, then Passport will not check the location in Cause IE. Enumeration: 'on': 1, 'off': 0.

This attribute specifies the time the network waits for the RESTART ACKNOWLEDGE message from the adjacent network after sending a first RESTART message. Upon timer expiry, another RESTART message is sent. After the second expiry, the interface is treated as idle. If the restartReqTimer attribute is set to the default value, then the interface is treated as idle when it receives an indication that the link is up and does not send a RESTART message.

This attribute specifies the time the local network waits for the processing of a RESTART message received by the interface. Upon expiry of this timer, an alarm will be displayed to report the problem. The timer value must be less than the restartReqTimer provisioned value at the adjacent node.

ContinuousBurst This mode of traffic generation creates traffic at the maximum rate possible until all of the frames have been sent. The generator then waits until the end of the timeInterval to begin again. IntervalBurst This algorithm attempts to generate 10 ms bursts of burstSize frames. It will generate as many of the burstSize frames as it can per sub-interval. DelayedBurst This algorithm generates bursts of burstSize frames separated by 10 ms delays. FixedBurst This aglorithm is similar to IntervalBurst, except a fixed burst size of 12 frames is used. delayMeasurement This algorithm is used to measure delay. The specified number of frames in the indicated pattern are generated, one at a time, with a maximum wait of maxDelay before sending the next frame. This algorithm is not implemented yet.

This group contains the attribute for a component's Customer Identifier (CID). Refer to the attribute description for a detailed explanation of CIDs.

An entry in the mscFrUniCidDataTable.

This attribute holds the Customer Identifier (CID). Every component has a CID. If a component has a cid attribute, the component's CID is the provisioned value of that attribute; otherwise the component inherits the CID of its parent. The top- level component has a CID of 0. Every operator session also has a CID, which is the CID provisioned for the operator's user ID. An operator will see only the stream data for components having a matching CID. Also, the operator will be allowed to issue commands for only those components which have a matching CID. An operator CID of 0 is used to identify the Network Manager (referred to as 'NetMan' in DPN). This CID matches the CID of any component. Values 1 to 8191 inclusive (equivalent to 'basic CIDs' in DPN) may be assigned to specific customers.

The percentage for each pool ranges from 0% to 1000% of the link rate. It allows for under or over subscription of the port. Under subscription occurs when the sum of the percentages assigned to the 16 pools is less than 100%. Over subscription occurs when the sum of the percentages for the 16 pools exceeds 100%. The default is full sharing of port capacity with three pre-set partitions.
