Description: Manages ATM interface configuration and statistics on AudioCodes media gateways, covering ATM PVC setup and AAL adaptation layer parameters.

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 AC-ATM-MIB?

AC-ATM-MIB is a vendor MIB from AudioCodes covering ATM (Asynchronous Transfer Mode) interface configuration and statistics on AudioCodes media gateways, including ATM permanent virtual circuit (PVC) setup and AAL (ATM Adaptation Layer) parameters. It exposes configuration data for ATM interfaces and PVCs along with associated traffic statistics, supporting the legacy TDM/ATM transport side of AudioCodes voice gateway products. In monitoring terms it would be used to track ATM PVC status and traffic counters to detect circuit failures or congestion on the ATM transport used to carry voice traffic, rather than reporting general chassis hardware health like temperature or fan status. It likely depends on the standard IETF ATM-MIB and AAL5-MIB conventions for its object structure, adapted with AudioCodes-specific extensions. It is typically deployed on AudioCodes media gateways that use ATM/AAL transport in telecom access or trunking scenarios. Engineers can download the AC-ATM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in AC-ATM-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 sample objects were provided for this module, so no concrete object or table names can be cited with confidence. In practice an operator would poll an ATM PVC table to check PVC operational status and cell/frame counters, watching for a PVC transitioning to a down state or showing rising discard counts as a sign of transport-layer trouble affecting voice quality. Any specific object names beyond this general description would be speculative given the lack of grounding data.
