Figure 11. Routing When All Local Links Have Failed, Group 0 Controlled by SIUA

If all the links between the controlling SIU and the adjacent signaling point fail, all transmit traffic is automatically routed to the adjacent signaling point through the inter-SIU link set as shown in Figure 11. The application should continue to use the SIU as before, directing all outgoing circuit requests to SIUA.

If the controlling SIU fails, the application is informed of the failure and should transfer control of the circuit group to the remaining unit.

■Calls in a steady state (speech) will continue uninter- rupted.

■Outgoing calls in a set-up state during the transfer should be re-attempted.

■Incoming calls being set-up by the interconnected SS7 equipment will also fail and will be re-attempted remotely.
