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 mscTraceRcvrX25DnaCugCugOptionsTable.

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 X.25 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 mscTraceRcvrX25DnaAddressTable.

This attribute indicates 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.

This group defines call options for outgoing calls.

An entry in the mscTraceRcvrX25DnaOutgoingOptionsTable.

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 class of routing (delay/ throughput) 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). This attribute, if set to a value of throughput, specifies that the default class of routing is throughput sensitive. If set to a value of delay, then the default class of routing is delay sensitive. This attribute is obsoleted. Please refer to defaultTransferPriority for the corresponding new attribute. Enumeration: 'delay': 1, 'throughput': 0.

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 group defines the call options for incoming calls.

This attribute specifies the default value for the number of data packets that can be received from the interface before any acknowledgment.

This attribute, if set to local specifies that packet sizes can be negotiated locally at the interface irrespective of the setting at the remote interface. If set to endtoEnd, then the packet size negotiation is between the local and remote interface (i.e. packet sizes are the same on both interfaces). Enumeration: 'endToEnd': 0, 'local': 1.

This attribute specifies the format to signal CUG indices as basic or extended. A basic CUG index format is two digits long. An extended CUG index format is four digits long. Enumeration: 'extended': 1, 'basic': 0.

*** 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 mscTraceSessionX25VcIntdTable.

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 *** ... Statistics(Stats) This group defines general attributes collected by general 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.

An entry in the mscTraceSessionX25VcStatsTable.

This attribute counts the number of ack stacking timer expiries. It is used as an indicator of the acknowledgment behavior across the subnet when ack stacking is in effect. If it expires often, usually this means end users will experience longer delay. The ack stacking timer specifies how long the Vc will wait before finally sending the subnet acknowledgment. if this attribute is set to a value of 0, then the Vc will automatically return acknowledgment packets without delay. If this attribute is set to a value other than zero, then the Vc will wait for this amount of time in an attempt to piggyback the acknowledgment packet on another credit or data packet. If the Vc cannot piggyback the acknowledgment packet within this time, then the packet is returned without piggybacking.

This attribute counts the number of subnet frames discarded due to the sequence number being out of range. Two Categories apply for the General Vc 1) lost Acks (previous Range) 2) unexpected Packets (next Range) Vc internally maintains its own sequence number of packet order and sequencing. Due to packet retransmission, Vc may receive duplicate packets that have the same Vc internal sequence number. Only 1 copy is accepted by the Vc and other copies of the same packets are detected through this count. This attribute can be used to record the frequency of packet retransmission due to Vc and other part of the subnet.

This attribute counts the number of subnet packets discarded due to duplication. It is used to detect software error fault or duplication caused by retransmitting.

This attribute counts the number of frames which have retransmission time-out. If packets from Vc into the subnet are discarded by the subnet, the source Vc will not receive any acknowledgment. The retransmission timer then expires and packets will be retransmitted again. Note that the Vc idle probe may be retransmitted and is included in this count. This statistics does not show the distribution of how many times packets are retransmitted (e.g. first retransmission results in successful packet forwarding).

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

This attribute indicates the peak size of the out of sequence queue. This attribute is used as an indicator of the sequencing behavior across the subnet. It records the largest body of out of sequence packets.

This attribute indicates the peak size of the sequence packet queue. This attribute is used as an indicator of the sequencing behavior across the subnet. It records the largest body of out of sequence packets, which by the receipt of an expected packet have been transformed to expected packets. The number of times this peak is reached is not recorded as it is traffic dependent.

This attribute indicates the peak size of wait acks. This attribute is used as an indicator of the acknowledgment behavior across the subnet. It records the largest collective acknowledgment.

This attribute counts the number of successful Vc recovery attempts. This attribute is used as an indicator of how many times the Vc path is broken but can be recovered. This attribute is useful to record the number of network path failures.

This attribute counts the number of window closures to subnet. A packet may have been sent into the subnet but its acknowledgment from the remote Vc has not yet been received. This is a 8 bit sequence number.This number is useful in detecting whether the Vc is sending any packet into the subnet.

This attribute counts the number of window closures from subnet. This attribute is useful in detecting whether the Vc is receiving any packet from the subnet.

This attribute displays the number of times the Vc stays within the W-R region. The W-R region is a value used to determined the timing of credit transmission. Should the current window size be beneath this value, the credits will be transmitted immediately. Otherwise, they will be transmitted later with actual data. The wrTriggers statistic is therefore used to analyze the flow control and credit mechanism.
