Overview

ACD traffic is routed through dual control C-LAN circuit packs on the 
switch. The Definity switch must be administered to enable the dual C-
LAN cards; for details about the administration of dual ACD links on HA 
systems, see 
Finally, note that the parts requirements and physical connection 
schemes described in this chapter are applicable to each switch-to-
server link installed on the HA system, irrespective of the total number of 
links connected to the server.
Connecting 
Blocks
2
In this chapter, references are made to 103A connecting blocks, which 
have one RJ45 connector per block. If needed, you can substitute 
the 104A connecting block, which has two RJ45 connectors per block. 
The wiring for both connecting blocks are identical.
Planning for LAN 
Switch Links
2
When setting up a switch link over a LAN, planning information must be 
gathered before you begin. You should also take into account if the 
Intuity™ AUDIX
®
 product will be part of the LAN. You must coordinate 
the setup of that system with the switch and the CMS. Some of the 
information needed includes:
How is the connection being made from the CMS computer to the 
switch:
a. Private LAN, no connectivity to customer LAN (uses private 
LAN addresses):
— Recommended option for HA systems, most robust and 
reliable, no dependency on customer’s network
— Hubs are used to make the connections; up to four hubs 
can be used to extend distances
— Crossover cable can be used instead of hubs (with flipped 
transmit/receive leads)
b. Customer LAN with private segment:
— Uses switch or router to provide a private collision domain
— Minimal dependency on customer’s network
— Customer must provide equipment and administer 
network for private segment
— Customer LAN administrator must be present during setup
