Lsp And Ess - Avaya ESS User Manual

IPSI Port Networks at once. This command must be issued from the ESS server or the
Main server(s) that intends to take control of the Port Network(s). For more information
see, get forced-takeover ipserver-interface
One at a time:
●
- get forced-takeover ipserver-interface port-network [1-64]: The get
forced-takeover ipserver-interface port-network SAT command followed
by the Port Network number provides the capability for an ESS server or Main server(s)
to manually take control of one IPSI Port Network. The command must be issued from
the ESS server or the Main server(s) that intends to take control of the Port Network(s).
For more information see,
When the Main server resumes control of a Port Network, the Port Network preforms a restart.

LSP and ESS

In the LSP option, based on network region settings, each IP endpoint and each G250, G350,
or G700 Media Gateway, are manually configured with a list of call controllers during
initialization. If for any reason, the communication between a G250, G350, or G700 Media
Gateway, and its primary controller stops, the media gateways and IP endpoints register with a
call controller on its list. If the LSP is in the list of call controllers, the media gateway and IP
endpoint register with the LSP. The media gateway must first register with a LSP prior to an IP
phone being able to register with the LSP. The LSP does not control other types of media
gateways such as the CMC1, G600, and G650 Media Gateways and has less capacity then an
ESS server.
In an ESS environment, the IPSI contains a priority list of ESS servers. If for any reason, the
communication between the IPSI and the Main server is lost, the IPSI requests service from the
highest ranking ESS server on its list. The ESS server accepts the request and assumes control
of the IPSI connected Port Networks.
The ESS server provides the same functionality and the same capacity as the Main server.
Through the Port Network's IPSI board, the ESS server can provide service to MCC1, CMC1,
SCC1, G600, and G650 Media Gateways. The ESS server can also provide service to each
G250, G350, or G700 Media Gateway through CLAN connections in the Port Networks.
LSPs are supported in an ESS environment.
