AT&T 3 manual 12Verifying System Operation and Troubleshooting

Troubleshooting

Message lights on multiple telephones are not

turned On and Off in a timely manner

Possible Cause Corrective Action

There is heavy call traffic and Outcalling volume on the mail system. The same port used for message light activation and deactivation is used for Outcalling and call handling.

Reduce Outcalling volume. If the problem is not resolved, consider adding more ports to the mail system.

The modular cord connecting the mail system Outcalling port to the communications system 206 module is loose.

Check the connections between the Outcalling port and the 206 module:

■On a two-port system, check the connection to port 2.

■On a four-port system, check the connection to port 4.

■On a six-port system, check the connections to ports 5 and 6.

If the problem occurs during times of heavy call traffic, there may be insufficient touch-tone receivers on the communications system modules, or there may be a defective touch-tone receiver.

Call for support as described on page 6-5.
