What Is Nortel-MsCarrier-MscPassport-VnetMcdnSigMIB?
Nortel-MsCarrier-MscPassport-VnetMcdnSigMIB is a Nortel enterprise MIB for the MsCarrier Passport platform, managing MCDN (Meridian Customer Defined Network) signalling channel parameters on virtual network interfaces. It exposes provisioning and status tables for MCDN signalling channels, including Layer 2 framing parameters like T200/T23 timers and N200 retry counts used in the signalling protocol. This MIB is largely configuration-oriented for telephony signalling, but its row status and Layer 2 parameter tables do allow monitoring whether a signalling channel is correctly provisioned and operational, which affects call setup reliability across the customer-defined network. It follows Nortel's Passport component/row-status MIB pattern shared with sibling MIBs like the IPIVC MIB. It was deployed on Nortel Passport WAN switches carrying MCDN telephony signalling for private branch networks. Engineers can download the Nortel-MsCarrier-MscPassport-VnetMcdnSigMIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-VnetMcdnSigMIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Nortel MsCarrier Passport WAN switch
Monitoring Examples
An administrator would check mscSigChanMcdnRowStatusTable via mscSigChanMcdnRowStatus to confirm an MCDN signalling channel is active, and inspect mscSigChanMcdnL2Table values such as mscSigChanMcdnT200 and mscSigChanMcdnN200 to verify Layer 2 link timers match expected values. Signalling channels stuck in a non-active row status would explain failed or delayed call setups across the MCDN network.
What Can Be Monitored
- MCDN signalling channel row status
- Layer 2 timer values (T200, T23)
- retry count (N200)
- signalling channel provisioning state

| U32 mscSigChanMcdnActiveChannels | 1.3.6.1.4.1.562.36.2.1.115.17.16.1.1 | Unsigned32 | read-only | This attribute indicates the number of currently active channels. This includes data and voice channels. |
| U32 mscSigChanMcdnActiveDataChannels | 1.3.6.1.4.1.562.36.2.1.115.17.16.1.3 | Unsigned32 | read-only | This attribute indicates the number of channels that are currently carrying data. This does not include modem data. |
| U32 mscSigChanMcdnActiveVoiceChannels | 1.3.6.1.4.1.562.36.2.1.115.17.16.1.2 | Unsigned32 | read-only | This attribute indicates the number of channels that are currently carrying voice. |
| INT mscSigChanMcdnAdminState | 1.3.6.1.4.1.562.36.2.1.115.17.14.1.1 | INTEGER | read-only | 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. |
| INT mscSigChanMcdnChanMaintenanceHandling | 1.3.6.1.4.1.562.36.2.1.115.17.13.1.5 | INTEGER | read-write | This attribute specifies handling of channel maintenance events such as locking and unlocking a channel or channel registration on start-up. The decision here is whether to send individual channel RESTART messages, SERVICE messages, or nothing. Note that channel registration only occurs after the global interface restart at startup. The attribute controls start-up handling absolutely, and channel lock and unlock conditionally. That is, setting this to enable SERVICE messages ensures SERVICE messages at start-up and whenever a channel goes into or out of service. However, if this is not set to enable SERVICE messaging, a RESTART is always sent on unlocking a channel. globalOnStartup provides the minimum required function at start- up, without any individual channel confirmation. Note that when this is set, channel RESTART is still used for channel unlock. globalOnStartup applies to SigChan start-up only. serviceMessage enables sending and receiving SERVICE messages. If enabled, SERVICE messages are always used for channel maintenance on channel lock, channel unlock and start-up. restartMessage provides individual channel RESTARTs when a SigChan starts up. If enabled, the RESTART is used at start-up and channel unlock. However, if both SERVICE and RESTART messages are disabled, the RESTART will still be used when a channel unlocks. |

| OCT mscSigChanMcdnClsFeaturesSupported | 1.3.6.1.4.1.562.36.2.1.115.17.18.1.2 | OCTET STRING | read-write | This attribute specifies the features to be supported by MCDN 'TCAP' connectionless messaging. Note that some features such as Network ACD combine connectionless and connection oriented. In the NACD case, the connectionless messaging enables the source and target PBXs to establish the networked relationship, and calls sent across the network (connection oriented) will contain basic information relating the call to the feature. Feature Definitions: networkAcd: transfer of a call from a pool of agents to a second pool of agents across the network. networkMessageService: message waiting capability (for example, lamps on sets). Also includes signalling for voice mail, but is not limited to voice mail. networkVoiceMail: a specific subset of Network Message Service, separated functionally as it always terminates on an interactive voice response mailbox application. networkRingAgain: ring again to remote sets. electronicLock: change of set capabilities by a remote user dialling the applicable code and password. remoteCallForward: call forwarding a phone via applicable code and password. callPickupNetworkWide (call pickup world wide): scan for a ringing call on another node, to enable the scanning set to pick up the call. networkPackage1: a collection of other features including but not limited to network clock synchronization. Note that on the Meridian 1, this is a general purpose group used for very small features not requiring a new ISDN Facility feature type. isdnApplicationInterface: network wide support of a number of Meridian 1 Application Module Link features. mobilityMultisiteNetworking: the capability to use a wireless phone in multiple sites, by having the phone register on arrival at the new site, and having the PBX at the new site negotiate the set 'relocation' with the base PBX. miscellaneous: Any feature that is not listed above.

Feature Definitions: networkAttendantService: network wide support of Attendant ('operator') services. classOfServiceTransport: this is not a ROSE feature. Class of Service transport takes place in the called party number when provisioned on the Meridian 1 to use an ESN signalling type. trunkRouteOptimization: dropping of redundant links in a call, when a set call forwards a call prior to answer. remoteVirtualQueuing: queuing at a remote node without requiring a B channel to be kept up. offHookQueuing: Queuing by maintaining the speech path to the queuing node. networkCallTrace: call progress tracing across a network (that is, call reached node a, node b, terminated at c,...). networkIntercom: network wide access to an intercom system onm a Meridian 1. callPickupNetworkWide: connection oriented messages associated with the TCAP call pickup scan operation. The messages that actually pick up the ringing call. radioPaging: access to a radio paging system network wide, allowing single radio paging facilities in a relatively dense local PBX network. networkAccess: information to enable access to PBX features from outside the network. Additional data is provided to identify access capabilities for a spoecific call. (Similar to transmittiong authorization code capabilities network wide.) antiTromboning: actually includes two capabilities - NAS (Network Attendant Setvice) and Trunk Anti-Tromboning. Calls that exit the subnet to a PBX and are transferred back to a network number via the same D channel can be optimized. If PBX A (Passport A) calls across the subnet to Passport B, D channel Z, to PBX B, and PBX B transfers across D channel Z to Passport B and therefore to PBX C/Passport C, this allows tha call to simplify to PBX/Passport A to PBX/Passport C. miscellaneous: Any feature that is not listed above.

| INT mscSigChanMcdnSide | 1.3.6.1.4.1.562.36.2.1.115.17.13.1.1 | INTEGER | read-write | This attribute specifies whether the interface provides layer 2 and 3 services equivalent to the ITU-T network or user side of the connection. If this attribute is set to network, then the interface is master during channel negotiation, and uses network side layer 2 command/response bits. If this attribute is set to user, then the interface is slave during channel negotiation, and uses user side layer 2 command/response bits. Note that although a peer to peer protocol has no true network or user side, for channel negotiation and layer 2 handling the peer to peer and UNI protocols have identical function. A true UNI may also have uni-directional messages and/or message elements; the peer to peer has all elements bidirectional. |

| OCT mscSigChanMcdnTracing | 1.3.6.1.4.1.562.36.2.1.115.17.17.1.1 | OCTET STRING | read-write | This attribute defines which types of tracing are active for this signalling channel. The tracing messages are sent to the debug stream. To see the messages the agentQueue attribute in Col/debug must be greater than 0 and a Telnet NMIS session must list the debug stream in in its data streams (ex. set nmis telnet session/1 dataStreams debug). Different types of tracing can be enabled simultaneously. Note that tracing consumes additional CPU resources and will slow down call processing on a heavily loaded card. If there is message block exhaustion tracing will be suspended for a period and then automatically reenabled. An alarm is generated on tracing suspension and resumption. This mechanism protects the function processor against excessive numbers of tracing messages. Types of tracing include: protocolErrors - get details of any protocol errors which are occuring. Protocol errors are also reported in summary form as alarms. q931Summary - Summary of the Q.931 messages on the signalling link, including certain call details (calling number, called number, release codes). q931Hex - Q.931 messages displayed in hex format. Useful to determine protocol compliance in case of errors reported on local or remote ends. q931Symbolic - Q.931 messages parsed to give maximum detail. Useful for understanding content of messages flowing on the link. portHex - Messages in hex format being sent and received on the link. Description of bits: protocolErrors(0) q931Summary(1) q931Hex(2) q931Symbolic(3) portHex(4) |
| INT mscSigChanMcdnUsageState | 1.3.6.1.4.1.562.36.2.1.115.17.14.1.3 | INTEGER | read-only | 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. |
