What Is SONUS-SS7-SERVICES-MIB?

SONUS-SS7-SERVICES-MIB is a vendor MIB from Sonus Networks for configuring and monitoring SS7 (Signaling System 7) signaling gateway services on their softswitch platforms, covering SS7 gateway instances and node-level configuration used for PSTN interconnection. It exposes gateway configuration and state objects including operational state, socket/connection type, active and primary host associations, host IP addressing, and out-of-service delay timers governing failover behavior between redundant signaling hosts. This is primarily a software/service-status monitoring MIB: administrators use it to confirm SS7 gateway instances are in the correct operational state and that primary/backup host redundancy is functioning, which is critical for call-signaling availability rather than physical hardware sensors. It depends on the SONUS-SMI enterprise root and typically operates alongside SONUS-TCAP-CLIENT-SERVICES-MIB (for transaction-layer SS7 services) and SONUS-NODE-RESOURCES-MIB for overall node health. Typical deployment context is carrier telecom networks where Sonus signaling gateways bridge SS7-based PSTN switches with IP-based softswitch call control. Engineers can download the SONUS-SS7-SERVICES-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SONUS-SS7-SERVICES-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

  • Sonus Networks (Ribbon Communications) SS7 signaling gateway/softswitch

Monitoring Examples

An admin would poll sonusSs7GatewayTable/sonusSs7GatewayEntry to check sonusSs7GatewayState and confirm which host is currently sonusSs7GatewayActiveHost, comparing it against the configured sonusSs7GatewayPriHostName/sonusSs7GatewayPriHostIpaddr. If the active host has failed over to a secondary unexpectedly, this would be visible as a mismatch between the active and primary host fields, prompting investigation into the primary's health. The sonusSs7GatewayPriHostOosDelayTimer setting would be checked to confirm failover timing is tuned appropriately to avoid signaling flaps during transient primary-host issues.

What Can Be Monitored

  • SS7 gateway operational state
  • active vs. primary signaling host
  • host IP addressing and socket type
  • out-of-service failover delay timing

How to Use in IPNetwork Monitor

Example using sonusSs7NodeCurrentState OID:

Select a Sonus Networks (Ribbon Communications) signaling gateway/softswitch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type sonusSs7NodeCurrentState into the Find box to locate it in the OID tree, then select it and click OK. The current state of this SS7 node connection. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is 'failed' or 'congested', since 'offline'/'disabled' can be intentional and 'active'/'initializing' are both normal operating states. Click Finish to create the monitor; you can adjust any parameter later.
