Cisco Cisco Administrative Workstation Installation Guide

A Peripheral Gateway (PG) that is collocated with one or both sides of the Central 
Controller can share the same visible LAN segment as the CallRouter and Logger 
nodes. The PG can communicate with the local CallRouter through the visible 
LAN. If the sides of the Central Controller are geographically separated, the PG 
communicates with the other side through the visible IP router and a WAN link. 
(If both sides of the Central Controller are collocated with the PG, then the PG 
communicates with both sides through the visible LAN.)

 shows the network connection for a PG at a central site.

The ACD itself can also be on the visible LAN.

If the PG is duplexed, then the two duplexed PGs must be connected through a 
separate private network. (They cannot use the same private network as the 
CallRouter and Logger.) See
