PMS-LINK (Property Management System Link)
MO Name in Log Alarm
Level
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
Initial Command to Run Full Name of MO
PMS-LINK MIN test pms-link long PMS Link
WRN test pms-link
● 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. The PMS
link to the processor is via a TN799 C-LAN port. For information about C-LAN connectivity, refer
to CLAN-BD (Control LAN Circuit Pack).
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.
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), Digital Line Port of a
TN754 Digital Line circuit pack, ADU, or Data Line Port of TN726B Data Line 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 test
pms-link fails, no alarm will be generated.
The list pms-down command lists every meaningful event to the PMS that occurred while
the link between the switch and the PMS was down. For example, any room status codes
entered by hotel housekeeping staff during a time of PMS outage would be shown in this report.
