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-PSTN-MIB?

This MIB manages PSTN trunk interface configuration -- ISDN PRI/BRI and CAS signaling -- on AudioCodes media gateways, devices that interconnect VoIP networks with the traditional telephone network. It centers on configuring signaling protocol selection and channel grouping for PSTN trunks, defining how digital trunk lines are set up on the gateway. Though no sample objects were provided, PSTN trunk MIBs of this kind typically also expose trunk/channel operational status, so this module likely lets an operator confirm whether configured trunks and their B-channels are in service, essential for detecting a failed span or signaling link. It would typically complement companion AudioCodes MIBs (such as AC-V5-MIB for V5 access signaling) for a full gateway status picture. It's deployed on AudioCodes media gateways providing TDM-to-VoIP interworking at a carrier or enterprise PSTN handoff point. Network engineers evaluating or troubleshooting this functionality can download the AC-PSTN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in AC-PSTN-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

  • AudioCodes media gateways

Monitoring Examples

No sample object names were provided for this module, so specific OID-level detail can't be given; in general, an admin managing such a gateway would configure and check the signaling protocol (PRI/BRI/CAS) and channel-group assignment per trunk, and would monitor trunk/channel status to detect a down span or D-channel signaling failure affecting call setup.

What Can Be Monitored

  • PSTN trunk signaling protocol
  • channel group assignment
  • trunk/channel status (if exposed)
