PMS-LINK (Property Management
System Link)
Property Management System (PMS) is a stand-alone computer system that a
hotel/motel-type and a hospital-type environment use for services such as
reservations, registration, messaging, housekeeping, night audit, billing, and
inventory. The PMS Link provides a communications channel between DEFINITY
Generic 1 or Generic 3iV2 and a customer-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 Communications System Generic 3 Feature Description
,
555-230-204 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 port on
the TN754 or TN754B Digital Line circuit pack, or through an ADU and a port on
the TN726 Digital Line circuit pack.
PMS Link Maintenance provides a strategy for maintaining the link between
DEFINITY Generic 1 and Generic 3iV2 and a PMS device. The strategy includes
a set of tests for periodic diagnosis, detection of errors during normal operation,
actions 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 immediately. 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 maintenance of the elements
composing the PMS physical link [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 pack, and Data
Channels on TN777 Network Control circuit pack]. If PMS Link Maintenance
cannot restore the PMS Link, then the maintenance tests of these individual
