3. Type the PMS message required to light a telephone’s message
waiting lamp, using CAPITAL letters only. See the following example.
4. Verify that the telephone’s message waiting lamp is lit.
 If the lamp is not lit, check the PMS-related logs in Maintenance. The
logs will indicate which section of the PMS message is invalid.
5. Type the PMS message required to turn off the telephone’s message
waiting lamp.
6. Verify that the telephone’s message waiting lamp is off.
Turning a telephone’s message waiting lamp on and off from a PC
confirms that the PBX’s PMS interface works correctly.
If problems continue when you reconnect the customer’s PMS computer,
check the maintenance logs for PMS related information, identifying
problems with the customer’s PMS hardware/software.
For the PMS to light a lamp station the Dial 0 for that tenant
must be a console, and the Dial 0 must be the same for Night
1 and Night 2.
Faster PMS PCs may have to be forced to wait for a reply
from the PBX.
