DEFINITY Network
The “main” DEFINITY cabinet may be a G3R, a G3SI, G3CSI, DEFINITY One, or an
Avaya IP-600. The DEFINITY cabinet may either be a PPN (Processor Port Network) or
an EPN (Expansion Port Network). The DEFINITY software must contain a Release 9 or
newer release software.
Two DEFINITY hardware boards are used to support the Remote Office; the C-LAN
(TN799C) and the IP Media Processor (TN2302AP). The C-LAN board is used to convey
signaling/control streams over to remote station endpoints and to remote trunks (that are
supported on the Avaya R300). The IP Media Processor card serves as the voice bearer
gateway and audio conference bridge for transporting TDM-based traffic from the
DEFINITY backplane (supporting traditional line and trunk cards) out to the IP-based
wide area network and on toward the Remote Office.The C-LAN and the IP Media
Processor must be in the same network region (as DEFINITY defines an IP networking
region). Figure 1 below shows the network topology for a DEFINITY ECS main system
with two subtending remote office configurations.

The “network” connection to the C-LAN card is a 10 BaseT and 100 BaseT Ethernet
connection. The “network” connection to the IP Media Processor is a 10/100 BaseT
Ethernet connection. This Ethernet output of these two cards is connected to the host LAN
which is a subnetwork consisting of data switches and/or hubs and interior routers.
