OBJECT-TYPE

What Is Nortel-MsCarrier-MscPassport-DataIsdnMIB?

Nortel-MsCarrier-MscPassport-DataIsdnMIB is a vendor-specific Nortel MIB for the MSCarrier Passport switching platform, focused on managing data-over-ISDN signaling channels and call configuration. It exposes provisioning and status data including row-status controlled signaling channel tables, per-channel component naming and storage type, and call identifier (CID) data tables tied to signaling channel indices. Its monitoring role centers on configuration and operational status of signaling channels: dsigChanRowStatus reflects whether a signaling channel entry is active, provisioned, or being modified, effectively indicating the operational readiness of that ISDN data path, while the CID data table supports tracking of call-level identification information for active or historical calls. Loading Nortel-MsCarrier-MscPassport-DataIsdnMIB in a MIB Browser exposes these signaling-channel, provisioning, and CID tables for inspection alongside the shared Passport component-naming conventions. It is a component-specific module within the broader Nortel MscPassport MIB family, implying dependency on shared Passport platform conventions for component naming and row-status conventions used elsewhere in that vendor's MIB suite. It is deployed on Nortel Passport multiservice switching platforms providing ISDN data services within carrier or enterprise WAN environments.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-DataIsdnMIB. 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.

What Can Be Monitored

  • signaling channel row status
  • channel provisioning state
  • component naming/storage type
  • call identifier (CID) data

Supported Devices

  • Nortel MscPassport multiservice switching platform

Monitoring Examples

An administrator would inspect mscDataSigChanRowStatusTable/mscDataSigChanRowStatusEntry, using mscDataSigChanIndex and mscDataSigChanRowStatus to confirm whether a given signaling channel is in the active state, and check mscDataSigChanComponentName for the platform's internal component identifier. The mscDataSigChanProvTable/mscDataSigChanProvEntry with mscDataSigChanCommentText allows administrators to see provisioning notes attached to a channel, while mscDataSigChanCidDataTable/mscDataSigChanCidDataEntry would be queried to correlate call identifier data for troubleshooting a specific ISDN data call. A signaling channel stuck in a non-active row status would indicate a provisioning failure preventing that ISDN path from carrying data traffic.

U32 mscDataSigChanCcCgCustomerIdentifier1.3.6.1.4.1.562.36.2.1.120.2.2.10.1.1Unsigned32read-writeThis 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.

mscDataSigChanCidDataTable1.3.6.1.4.1.562.36.2.1.120.101not-accessibleThis group contains the attribute for a component's Customer Identifier (CID). Refer to the attribute description for a detailed explanation of CIDs.

U32 mscDataSigChanCustomerIdentifier1.3.6.1.4.1.562.36.2.1.120.101.1.1Unsigned32read-writeThis 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.

mscDataSigChanStateTable1.3.6.1.4.1.562.36.2.1.120.103not-accessibleThis 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.

INT mscDataSigChanAdminState1.3.6.1.4.1.562.36.2.1.120.103.1.1INTEGERread-onlyThis 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 mscDataSigChanOperationalState1.3.6.1.4.1.562.36.2.1.120.103.1.2INTEGERread-onlyThis 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.
INT mscDataSigChanUsageState1.3.6.1.4.1.562.36.2.1.120.103.1.3INTEGERread-onlyThis 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.
mscDataSigChanOperStatusTable1.3.6.1.4.1.562.36.2.1.120.104not-accessibleThis group includes the Operational Status attribute. This attribute defines the current operational state of this component.

The up state indicates the interface is operational and capable of forwarding packets. The down state indicates the interface is not operational, thus unable to forward packets. testing state indicates that no operational packets can be passed.

FAQ

How would I check whether a data-over-ISDN signaling channel is active on a Nortel MscPassport switch?
The MIB exposes dsigChanRowStatus, which reflects whether a signaling channel entry is active, provisioned, or being modified — effectively the operational readiness of that ISDN data path. An engineer maintaining ISDN data services on a Passport platform can poll this status to confirm a signaling channel is correctly provisioned before troubleshooting a call failure further.

Does Nortel-MsCarrier-MscPassport-DataIsdnMIB help with tracking individual ISDN calls?
Yes — it includes a call identifier (CID) data table tied to signaling channel indices, which supports tracking call-level identification information for active or historical calls. This is useful when investigating a specific customer-reported ISDN call issue on a carrier's Passport switching platform.
