Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ASCEND-MIBSS7NMI-MIB?

ASCEND-MIBSS7NMI-MIB is a proprietary Ascend Communications MIB providing an SS7 network management interface for signaling configuration on Ascend telephony/integrated-access equipment. It exposes configuration and status data for SS7 signaling links, linksets, and point codes used in PSTN interworking. Its monitoring focus is software/service status of the signaling stack: whether signaling links are up, whether linksets are congested, and whether point-code routing is functioning, which directly affects call-setup capability rather than physical hardware sensors. It is used alongside voice/telephony interface MIBs (e.g. T1/E1 or channelized interface modules) since SS7 signaling rides over those physical circuits. It was deployed in Ascend media gateway and integrated access equipment interfacing with carrier SS7 networks. Engineers can download the ASCEND-MIBSS7NMI-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-MIBSS7NMI-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.

Monitoring Examples

An operator would poll the SS7 link and linkset status tables (an ascendSs7LinkTable/ascendSs7LinksetEntry style structure) to confirm signaling links are in-service and not congested, treating a link reporting 'out of service' or a linkset showing congestion as the likely cause of failed call setups on that route. Because no sample objects were provided for this MIB, these names are inferred from the stated SS7 signaling purpose rather than confirmed source identifiers.

What Can Be Monitored

SS7 signaling link status
linkset congestion state
point code configuration
signaling link in-service/out-of-service state
