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. The PMS 
link to the processor is via a TN799 C-LAN port. For information about C-LAN connectivity, refer 
to 
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.
