4.3 PLM (Phone Line Monitoring)

The Phone Line Monitoring (PLM) feature verifies the operability of the end-to-end
communications link (e.g. for elevator phone connecting to a live phone line) as required
by ASME A17.1/CSA B44 Code. Any fault detected generates an audible and visual
alert in the elevator lobby for the assigned group (elevator phones assigned to group #0
will not generate a PLM alarm). In an alarm state the communication link is re-tried
every five minutes until the failed status is cleared.

4.4 Phone LINE TEST

A phone LINE TEST feature enables on-site personnel who have access to the
consolidator keypad to go off-hook, listen for dial tone and call any number to test the
phone line operability. A similar off-site calling feature is available from any on-site
remote handset.
