What Is SONUS-DS1-MIB?

SONUS-DS1-MIB is a vendor MIB from Sonus Networks for managing DS1 (T1) TDM trunk interfaces on its softswitch/media gateway platforms. It exposes an administrative table for DS1 interface configuration, including shelf/slot/port location indices, association with parent DS3 interfaces, row status, profile name, and a mapped standard interface index (ifIndex), plus per-interface administrative state. Its monitoring value is centered on hardware/interface status: administrators track sonusDsx1AdmnState to confirm a DS1 trunk interface is enabled and operational, and use the shelf/slot/port/DS3/DS1 indexing to pinpoint exactly which physical trunk card and port a fault or alarm relates to. It explicitly ties into the standard IF-MIB via sonusDsx1AdmnIfIndex, and works alongside Sonus's DS3 and CAS MIBs since DS1 interfaces are nested under DS3 interfaces and often carry CAS-signaled trunks. Typical deployment is in carrier voice networks where Sonus gateways terminate T1/DS1 TDM trunks for interconnection with the PSTN or enterprise PBXs. Network engineers evaluating or troubleshooting this functionality can download the SONUS-DS1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SONUS-DS1-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 sonusDsx1AdmnTable (via sonusDsx1AdmnShelfIndex, sonusDsx1AdmnSlotIndex, sonusDsx1AdmnPortIndex, and sonusDsx1AdmnDs1Index) to confirm a specific DS1 interface's sonusDsx1AdmnState is active, and cross-reference sonusDsx1AdmnIfIndex against standard interface counters for utilization or error stats. A DS1 interface unexpectedly reporting a down or disabled sonusDsx1AdmnState would indicate a physical trunk card fault or a carrier-side T1 outage. Checking sonusDsx1AdmnDs3Index helps trace which parent DS3 span and card the affected DS1 channel belongs to, narrowing down the hardware root cause.

What Can Be Monitored

  • DS1 interface administrative state
  • shelf/slot/port trunk location
  • DS3-to-DS1 channel mapping
  • trunk interface configuration/profile
