PMS-LINK (Property Management
System Link)
System Link)
Property Management System (PMS) is a stand-alone computer system that
environments such as hotels or hospitals use for services such as reservations,
registration, messaging, housekeeping, night audit, billing, and inventory. The
PMS Link provides a communications channel between the switch and the
customer-owned PMS so that the PMS can interrogate the system for information
related to the following features:

Refer to
DEFINITY Communications System Generic 3 Feature Description,
555-230-204, for details of the PMS feature. The PMS device connects to the
system via a data module (PDM, MPDM, DTDM) connected to a port on a TN754
Digital Line circuit pack which is administered as a data extension. A PMS device
can also be connected through an ADU to a port on TN726B. The PMS link to the
processor is via a system port. A system port is comprised of a port on the
TN726B Data Line circuit pack and a port on the TN553 Packet Data circuit pack
connected to each other in a null-modem fashion. Refer to the PDATA-PT section
for information on the system port connectivity.

PMS Link maintenance provides a strategy for maintaining the link between the
switch 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 Link Setup fails, PMS Link Maintenance will wait for five
minutes before the next retry. If the number of retries reaches a threshold (12), a
Minor alarm is raised for service attention.
