SS7 Link OOS Handling

 

Configuration:

Screen capture below displays how to enable the IMG so that if an SS7 link goes Out Of Service that the associated CIC's stay in service either a set amount of time, or till certain conditions are met. Screen capture below was taken from IMG set up as an E1 box (ITU). The procedure is the same for T1 (ANSI).

 

Note: Feature F-5134 SS7 Link Out Of Service was added to software 10.5.2_ER3 only. The feature was not added to any other build until 10.5.3_ER1. From there, all subsequent builds after 10.5.3_ER1 will have the feature in it.

Functionality:

Disable (Default) - Functionality is same as previous software. If Signaling Link goes Out Of Service, then the associated CIC's will go Out Of Service as well.

Enable - If signaling link goes Out Of Service all associated CIC's which are in the idle state will go Out Of Service. If any CIC's are in either the ringing or connected state the CIC's will not go Out Of Service until a later subsequent condition occurs as described below.
