PMS-LINK (Property Management
System Link)
Property Management System (PMS) is a stand-alone computer system that a
hotel/motel-type and a hospital-type environment use for services such as
reservations, registration, messaging, housekeeping, night audit, billing, and
inventory. The PMS Link provides a communications channel between a
customer-owned PMS so that the PMS can interrogate the system about the
information related to the following features:
■
Message Waiting Notification
■
Controlled Restriction
■
Housekeeping Status
■
Check-in/Check-out
■
Room Change/Room Swap
Refer to Administrator’s Guide for Avaya MultiVantage Software for details on the
PMS feature. The PMS Link is administered to a data extension that provides a
standard EIA 232C interface to the PMS. A PMS can be connected through a data
module (PDM, MPDM, DTDM) and a port on the TN754 or TN754B Digital Line
circuit pack, or through an ADU and a port on the TN726 Digital Line circuit pack.
A PMS can also be connected through the TN799 CLAN circuit pack using
asynchronous TCP/IP links.
The PMS Link Maintenance 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 trial
of "Link Setup" fails, PMS Link Maintenance waits for five minutes before the next
retry. If the number of retries reaches the value of 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 (for example, the external PMS device, Data
Module (PDM/MPDM/DTDM), and Digital Line Port of TN754 or TN754B Digital
Line circuit pack, ADU and Data Line Port of TN726 Data Link 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 system technician-demanded test pms-link command fails, no alarm is
generated.
