Ipsi Configuration; Network Design - Avaya Application Solutions Deployment Manual

Implementing Communication Manager on a data network

IPSI configuration

DHCP is not available in an IP-Connect system. IPSI cards must be administered manually
through the services ethernet interface on the front of the card.

Network design

Proper network design is very important in an IP-Connect system. Because port network control
traffic is flowing across a customer's network, and not isolated on a control network, suboptimal
network design may lead to stability problems on the port networks.
Figure 90: Server farm placement in network configuration
In general, both S8700 Media Servers and G650 Media Gateways should be treated as servers
for the purpose of network placement. They should be connected into a server farm utilizing
redundant switches. If the network path between the S8700 media servers and the G650
gateways is disrupted for more than a few seconds, the port network could reset, disrupting
calls to the PSTN. Because stability is a concern, G650s should not be connected on the same
subnet as user PCs. One such configuration of G650 media gateways is shown in
