Avaya 555-245-600 manual S8700 / G700 / G350 system with Local Survivable Processors

Evolution from circuit-switched to IP

Consolidating remote site servers into an S8700 system requires a G700 or G350 Media Gateway with the option of Local Survivable Processors (LSP) (Figure 46: S8700 / G700 / G350 system with Local Survivable Processors). The LSP can be an S8300 or S8500 Server. In the event of a network or processor failure, the LSP takes over active call processing and gateway and endpoint management for the remote site, allowing continued operation with no loss of features until the outage is repaired.

Because the G700 and G350 rely on IP Telephony technology, this option is especially attractive to customers who decide to use a majority of IP endpoints at the remote site. This solution will, however, continue to support analog endpoints and DCP endpoints. Analog trunks and ISDN trunks are also supported. To decrease operational expenses, the circuit-switched trunks back to the main site can be replaced with IP trunks.
