8300 Media Server in an LSP mode

The LSP is located in the G700 Media Gateway and provides survivability when the S8700 Media Server is inaccessible. Each S8700 Media Server can have up to 50 LSPs. The LSP has a copy of the S8700 Media Server customer translations. The translations are updated regularly from the S8700 Media Server using a virtual link through a IP network. Typically, all LSPs are in idle mode, where the LSP is not processing any calls. When the Media Gateway's Processor (MGP) or IP endpoints perceive the Avaya media server to be unreachable, the MGP or IP endpoints will attempt to register with an LSP. The LSP does not actively take over when the primary controller becomes unreachable, but waits for MGPs and IP endpoints to register with it. Switchback from the LSP to the primary Avaya media server is a manual operation requiring a reset 3 command on the LSP.
