code message characters
n

message characters.

PMS problems typically occur in these areas:
n
PMS Protocol settings:
Ensure that the communication
parameters between the systems match.
n
PMS Programming:
Verify that all the recommended PMS and
Dataset programming is complete.
n
PMS Cabling:
Use a straight-through cable between the customer’s
PMS computer and the Dataset.
Test the PBX’s PMS interface as follows:
1. Disconnect the customer’s PMS computer from the Dataset.
2. Connect a personal computer or terminal to the Dataset’s RS-232
port.
n
Ensure that the communications parameters of the personal
computer / terminal match those expected by the PBX’s PMS
interface.
n
Verify that you receive the
ENQ
uire character from the PBX’s PMS
interface. If not, verify that all the programming and the connections
are correct.
3. Type the PMS message required to light a telephone’s message
waiting lamp, using CAPITAL letters only. See the following
