PMS-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:
Message Waiting Notification
Controlled Restriction
Housekeeping Status
Check-in/Check-out
Room Change/Room Swap
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 about 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.
