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 Avaya
DEFINITY Server 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
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. A PMS
can also be connected via a TCP/IP link to a port on the TN799 CLAN circuit pack.
PMS Link Maintenance provides a strategy for maintaining the link between
Avaya DEFINITY Server 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
components of the PMS Link must be executed to diagnose faults. If system
technician-demanded test pms-link command fails, no alarm is generated.
