Abstract

A method for providing switch translations upon a failure in the conventional recent change message handling system. The failure results in triggering a common channel signaling inquiry, to a signaling control point which responds with instructions for setting up a common channel signaling link between the Recent Change Memory Administration Center (RCMAC) to an alternate Remote Memory Administration System (RMAS). The RCMAC then delivers the recent change message to the alternate RMAS and the RMAS delivers the recent change signal to the addressed switch. In an alternate embodiment the Signal Control Point is provided with RMAS capability. This RMAS capability is then used in place of the alternate RMAS and the SCP sets up a path from the SCP associated RMAS to the RCMAC and to the addressed switch. The communication from the RCMAC which initiated the inquiry to the SCP and RMAS associated therewith is in common channel signaling protocol. The signal from the SCP associated RMAS to the addressed switch may be either in recent change protocol or common channel signaling protocol. In the latter instance the addressed switch is provided with a protocol conversion capability to convert the CCS protocol to recent change protocol to effect the switch translation.
