■ Printers
The Okidata
®
Models 320, 321, and 184T are often used for
hospitality installations, but be aware that other printers may be
delivered on site.
■ Miscellaneous equipment.
■ If the INTUITY Lodging Call Accounting co-resident application from
Homisco has been ordered, part of the miscellaneous equipment is
a set of adapters, cables, and user documentation used with the
INTUITY system. This equipment is packaged in a separate box
with the INTUITY equipment and is labeled “Hold for Homisco
Technicians - Do Not Discard!” Save this equipment for the Homisco
technicians.
2. Locate the equipment room and lay out the equipment room floor plan. If
possible, use standard floor plans as described in
DEFINITY ECS System
Description
. When laying out the equipment locations, consider the
following:
■ The switch-to-MAP link distance limitations depend on whether you
are using Transmission Control Protocol/Internet Protocol (TCP/IP),
X.25, or Mode Code:
— The TCP/IP link using the crossover cord is 328 feet (100
meters). This is the default configuration.
— The TCP/IP link using a 10/100base-T auto-sensing hub or
router is 656 feet (200 meters). This can be 328 feet (100
meters) on either side of the hub or router.
— The Isolating Data Interface (IDI) X.25 link must be 200 feet
(61 meters) or less. This link is used only on an upgraded
system if TCP/IP is not used. Duplicated
si
systems must use
data modules instead of IDI, so the distance limit is not an
issue.
— The Mode Code link is done over the same analog voice
ports connected between the switch and the voice messaging
adjunct. The analog ports have a distance limit of 20000 feet
(6100 meters). This connection is limited to upgraded
systems; the default configuration is TCP/IP.
■ The link between the switch and the INTUITY Lodging Call
Accounting on the MAP is limited to 50 feet (15.2 meters) unless you
use DCP data modules to extend the distance. When using a
stand-alone call accounting system, there is still the 50 foot (15.2
meter) limit that can be extended with DCP data modules.
