TOPOLOGIES
This section describes typical IP network architectures for implementing the Alcatel OmniPCX Office
Voice over IP services.
The following topology is recommended for connecting up an Alcatel OmniPCX Office:
The bandwidth of an Ethernet LAN can be 10 or 100 Mbps. If the network operates at 100 Mbps, ad-
ding terminals operating at 10 Mbps risks downgrading the bandwidth used by VoIP and hence audio
quality: you might need to isolate these devices on external LAN switches hooked up to the system.
CoCPU boards are connected to the local client network using a LAN switch; this solution helps reduce
Ethernet traffic on the CoCPU board.
