Description: Manages ATM signaling protocol configuration and call processing on Ascend ATM equipment.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. 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-MIBATMSIG-MIB?

This proprietary Ascend Communications MIB manages ATM signaling protocol configuration and call processing on Ascend ATM equipment, covering the UNI/NNI signaling used to set up and tear down ATM virtual connections. It exposes configuration data for the signaling protocol as well as call-processing/state information for in-progress ATM calls. It supports monitoring of software call-processing health — an operator watches active call counts and signaling state to confirm calls are being set up and released correctly, spotting a signaling failure that would prevent new ATM connections from being established. It works closely with the Ascend base and QoS ATM MIBs, since successful call setup depends on both signaling and negotiated QoS parameters, per ATM Forum UNI signaling standards. It was deployed on legacy Ascend/Lucent ATM switches in carrier networks handling switched virtual circuit (SVC) traffic. Engineers can download the ASCEND-MIBATMSIG-MIB file directly to load it into their MIB browser.

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

No specific object or table names were included in the sampled instrumentation for this module, so a concrete polling example can't be tied to real OIDs; in general, an operator would monitor ATM call/signaling state objects to confirm switched virtual circuits are being set up and torn down successfully, investigating a rise in failed call attempts as a sign of a signaling protocol problem.

What Can Be Monitored

ATM signaling protocol state
active/failed call counts
call setup and teardown status
