PMS-LINK (Property Management System Link)
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 the test
pms-link command 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.
Procedures for Restoring the PMS Link
1. Determine the status of the PMS Link.
Enter status pms command and make sure that the PMS Link is not
busied out for maintenance. If the link is "down," then continue with the
next step.
2. Where does the PMS Link connect?
Enter display system hospitality and find out the destinations of the PMS
Link.
3. Determine the status of the data extension.
Enter status data extension command and verify whether the data
extension is in the in-service/idle state. If the data extension is NOT
available, then look for the extension number in Alt Name field of
Hardware Error Log. See
8-1374
4. Is the external PMS device available?
Make sure that the PMS device is ON-LINE and ready for service. Check
the physical connectivity between Data Module and the PMS device.
5. If the problem is not found in the above steps, check the system port for
any problems. Refer to the PDATA-PT section for description about
system port and its connectivity.
When restoring the PMS link, it is necessary to execute maintenance test on
different objects that comprise the PMS link. It is recommended that you busyout
the PMS link before trying to restore the link. When the PMS Link is busied out,
every PMS Link maintenance action is deactivated, and interference with tests of
other MOs is prevented.
