Implementing Communication Manager on a data network

S8700 / S8300 LSP
The S8700 server pair can also be used to control a G700 or G350 media gateway. For
survivability, an S8300 server running in Local Survivable Processor (LSP) mode can take over
control of up to 50 G700 or G350s and all associated endpoints in case of a network failure.
Security
Because both the S8700 servers and the S8300 server can support modems, it is important to
consider using access-lists and firewalls to isolate servers and media gateways from the rest of
the data network. Appendix B has information necessary for establishing access-lists or setting
up a firewall policy. Avaya has worked on hardening Avaya Application Solutions products
against penetration and denial of service attacks. For more information see

G700/G350 connections to the C-LAN
A G700 or G350 uses H.248 signaling with its controller. If the G700/G350 is homed off of an
S8700 server pair, it must be able to reach a C-LAN for its signaling connection. The G700 or
G350 gateway does not communicate directly with an S8700. This restriction does not apply
when controlled by an S8300 Media Server. The G700 or G350 would communicate directly
with the S8300 server, and not a C-LAN, in that case.
LSP-to-S8700 connection
In order to ensure up-to-date translations, an S8300 Media Server configured as an LSP must
be able to communicate directly over the IP network with the S8700 server pair. Communication
Manager uses rsync to synchronize translations between the S8700 servers and their LSPs.
This communications channel does not use a C-LAN. The S8300 must communicate with a
C-LAN circuit pack for keepalive traffic.
