Installing the System
19Connecting the Hospitality Adjuncts
Switch-to-INTUITY Admin Link (TCP/IP)
This data link transfers information to support the INTUITY AUDIX service for
office staff voice messaging. For all new installations, this is the recommended
way to connect the switch to the MAP for voice messaging administrative
messages. If the system is an upgrade, you may reuse the X.25 hardware for this
connection; see “Switch-to-INTUITY Admin Link (X.25)” on page 22. For
installations using Mode Code integration, see “Switch-to-INTUITY Admin Link
(Mode Code Integration)” on page 24.
Parts List
■ An ethernet port on the C-LAN circuit pack
■ One 259A adapter (comcode 102631413), or
UTP Category 5 cross-connect hardware and connecting blocks
■ One 6-inch RJ45 crossover cord (comcode 846943306 or 104154414), or
One 10/100Base-T auto-sensing LAN hub or customer router (optional)
■ One or two RJ45 UTP Category 5 modular cords (see “Appendix A —
Parts List” on page 242)
■ One or more 451A in-line RJ45 adapters, as needed (used to connect
modular cords together)
■ One LAN card on the MAP (for INTUITY R4.4, model 8412; for INTUITY
R5, model 8416).
Distance Limits
Using the standard crossover cord (or alternate crossover wiring arrangement in
Figure 5), the distance limit between the switch and the MAP is 328 feet (100
meters).
Using a hub or customer router, the distance limit between the switch and the
MAP is 656 feet (200 meters) total [328 feet (100 meters) from the switch to the
hub or router, and 328 feet (100 meters) from the hub or router to the MAP]. If the
distance between the switch and the MAP is more than 656 feet (200 meters), you
can daisy-chain up to four separate hubs.
NOTE:
If you do locate the switch more than 50 feet (15.2 meters) from the MAP
and are using the coresident INTUITY Lodging Call Accounting system on
the MAP, the call accounting link limit of 50 feet (15.2 meters) must be
taken into account. Figure 15 shows how the call accounting link can be
extended beyond that limit.
