What Is CPM-NORTEL-MIB?
CPM-NORTEL-MIB manages Nortel Customer Premises Modem (CPM) devices, DSL customer-premises equipment, with a focus on dial-backup access functionality alongside the modem's primary broadband connection. Its dialaccess-related objects expose configuration and status for the dial-on-demand backup path that a CPM can use when the primary DSL line is degraded or down, making this fundamentally a line-status/failover monitoring MIB rather than a general traffic-statistics module. For hardware/software status monitoring, tracking dial-backup activation is a direct proxy for DSL line health: if a modem has fallen back to dial access, that's a clear signal of a primary-line fault. It is a Nortel-specific private MIB for this legacy CPM device rather than an extension of a broader DSL standard like the ADSL-LINE-MIB, though it addresses a similar problem domain. It was deployed on Nortel CPM DSL modems at customer premises where dial backup provided resilience against DSL outages. Network engineers evaluating or troubleshooting this functionality can download the CPM-NORTEL-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CPM-NORTEL-MIB. 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 CPM (Customer Premises Modem) DSL device
Monitoring Examples
An operator polling the dialaccess objects on a Nortel CPM would check whether the dial-backup path is currently active, which indicates the modem has failed over from its primary DSL connection. A sustained dial-backup state across many CPM units in a region would point to a broader DSL access-network outage rather than an isolated line fault.
What Can Be Monitored
- dial-backup access activation status
- DSL line connection/failover state
