PMS-LINK (Property Management System Link)
Property Management System (PMS) is a stand-alone computer system that a
hotel/motel-type and a hosp ital-type environment use for services such as
reservations, registration, messaging , housekeeping, nigh t audit, billing, and
inventory. The PMS Link provides a communications channel between DEFINITY
Generic 1 or Generic 3iV2 and a c ustomer-owned PMSs so that the PMS can
interrogate the system about the information related to the following features:
■Message Waiting Notification
■Controlled Restriction
■Housekeeping Status
■Check-in/Check-out
■Room Change/Room Swap
Refer to

DEFINITY Enterprise Communications System Admini strator’s Guide

for
details on the PMS feature. The PMS Link is administered to a data extension that
provides a standard EIA 232C interface to the PMS. A PMS can be connected
through a data module (PDM, MPDM, DTDM) and a por t on the TN754 or
TN754B Digital Line circuit pac k, or through an ADU and a p ort on the TN726
Digital Line circuit p ack.
The PMS Link Main tenance strategy includes a set of tests for periodic diagnosis,
detection of errors during normal operation, actio ns for troubleshooting, and
raising alarms for serious problems . PMS Link Maintenance uses a "try-and-wait"
mechanism for maintaining the PMS Link. If a PMS Link is torn down due to an
error, PMS Link Maintenance attempts to bring up the link immed iately. If the trial
of "Link Setup" fails, PMS Link Maintenance waits for five minutes before the next
retry. If the number of retries reaches the value of a threshold (12), a Minor alarm
is raised for service attention.
PMS Link Maintenance does not cover the maintenanc e of the elements
composing the PMS physical li nk (for example, the external PMS device, Data
Module (PDM/MPDM/DTDM), and Digital Line Port of TN754 or TN754B Digital
Line circuit pack , ADU and Data Line Port of TN726 Data Link circuit p ack). If
PMS Link Maintenance cannot restore the PMS Link, then the maintenance tests
of these individual comp onents of the PMS Link must be executed to d iagnose
faults. If system technician-demand ed test pms-link command fails, no alarm is
generated.
