20 Installing and Configuring the Avaya S8700-Series Server January 2008
Modem options
You set the modem options when you configure the server. You do not set options on the
modems themselves.
About media gateways
In a new installation, the S8700-series Servers work with only the Avaya G650 Media Gateway.
In a migration, the S8700-series Servers work with Avaya MCC1 and SCC1 Media Gateways in
a fiber-PNC configuration and G600 or CMC1 Media Gateways in an IP-PNC configuration.
The servers also work with Avaya G150, G250, G350, G450 and G700 Media Gateways. These
gateways register with the server either through the Processor Ethernet interface or through a
TN799DP C-LAN circuit pack.
Media gateways usually are installed in the same equipment room as the server rack hardware
or control network. However, you can install the media gateways in another location, including
another state or country.
About Processor Ethernet
Like a C-LAN circuit pack, Processor Ethernet provides connectivity to IP endpoints, gateways,
and adjuncts. The PE interface is a logical connection in the Communication Manager software
that uses a port on the NIC in the server. No additional hardware is needed to implement PE.
Starting with Release 3.1 of Communication Manager, the PE interface is enabled on the
S8700-Series Server to allow enhanced flexibility to connect to gateways, endpoints, and
adjuncts.
The PE interface is always enabled on an S8700-series Server pair for registration by an ESS
or an LSP. However, the PE interface is not supported on duplex servers for registration by an
H.248 gateway, H.323 endpoints, or adjuncts.
