Planning for LAN Switch Links
ACD traffic is routed through dual control
Finally, note that the parts requirements and physical connection schemes described in this chapter are applicable to each
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.
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
