Attributes in this group define ClosedUserGroup options associated with interlockCode. Dnas with the same CUG (interlockCode) can make calls within this group. Various combinations of attributes are defined under this option which permit or prevent calls in the same CUG group.

An entry in the mscTraceRcvrFrDnaCugCugOptionsTable.

This attribute specifies the CUG type as either national or international. A national CUG has significance within the local network only. An international CUG has significance across network boundaries. Enumeration: 'international': 1, 'national': 0.

This attribute specifies the Data Network ID Code of the network that is administering the international CUG. This attribute is not used for a national CUG and should be left at its default value. The dnic value is not an arbitrary number. It is assigned by international agreement and controlled by ITU-T.

This attribute specifies a numeric identifier of a national or international closed user group. It is an arbitrary number. This attribute may also be called CUG in some descriptions. Dnas defined with this number can only make calls to Dnas defined with the same interlockCode.

This attribute specifies that this Cug is to be used on all outgoing calls to the Frame Relay trace receiver. Enumeration: 'yes': 1, 'no': 0.

This attribute specifies that outgoing calls (from the DTE into the network) can be made using this particular Cug. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute specifies that incoming calls (from the network to the DTE) cannot be accepted using this Cug. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute specifies that this Cug is privileged. For a call between two closed user group Dnas to connect, at least one Dna must have a privileged Cug. Enumeration: 'yes': 1, 'no': 0.

This group contains attributes common to all Dnas. This group is composed of two attributes which define a Dna. These attributes are used to interpret the format of the address digits.

An entry in the mscTraceRcvrFrDnaAddressTable.

This attribute specifies the Numbering Plan Indicator (NPI) of the Dna that is entered. The address may belong to an E.164 or X.121 plan. Enumeration: 'e164': 1, 'x121': 0.

The Dna attribute contains digits which form a unique identifier for the calling end of the trace connection. Dna digits are selected and assigned by network operators. The maximum Dna length is 15 digits.

An entry in the mscTraceRcvrFrDnaOutgoingOptionsTable.

This attribute specifies that outgoing calls (from the DTE to the network) can be made using this particular Dna component. Enumeration: 'disallowed': 0, 'allowed': 1.

If this attribute is set to normal, then the default priority for outgoing calls (from the DTE to the network) using this particular Dna is normal priority when the priority is not specified in the call. If this attribute is set to high then the default priority for outgoing calls using this particular Dna is high priority. Enumeration: 'high': 1, 'normal': 0.

This attribute specifies that outgoing international calls (from the DTE to the network) can be made using this particular Dna. This attribute also controls access to another numbering plan, and specifies that cross-numbering plan calls are allowed. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute specifies the default reliability class of routing for all calls (from the DTE to the network) using this particular Dna. The chosen default reliability class of routing normally applies to all packets (including the call packets) travelling into the network. A value of high specifies that packets are to be 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. The VC handles the duplication and disordering to ensure that packets are delivered to the interface in the proper sequence and without duplication. Enumeration: 'high': 0, 'normal': 1.

This attribute specifies that the called end of the connection will not use the calling end provisioning data for reliability class of routing to override the provisioning data at the called end. Enumeration: 'yes': 1, 'no': 0.

This attribute specifies that reliability routing signaling is not used. Enumeration: 'disallowed': 0, 'allowed': 1.

This attribute is an extension of the Closed User Group (CUG) facility. If this attribute is set to a value of allowed, it specifies 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 interfaces that have Incoming Access capabilities. If set to a value of disallowed, then such calls cannot be made using this Dna (the calls will be cleared by the local DCE). This attribute corresponds to the ITU-T 'Closed User Group with Outgoing Access' feature. Enumeration: 'disallowed': 0, 'allowed': 1.

*** THIS TABLE CURRENTLY NOT IMPLEMENTED *** 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 mscTraceSessionFrVcIntdTable.

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 TABLE CURRENTLY NOT IMPLEMENTED *** 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 mscTraceSessionFrVcFrdTable.

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 TABLE CURRENTLY NOT IMPLEMENTED *** 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.
