Telephone Troubleshooting

This section discusses general functions on a variety of key telephones available for use on the
system. It is assumed that basic troubleshooting skills in the identification and resolution of
basic problems are already possessed (e.g. static/noise heard on conversation, one phone only,
replace worn handset cord).

Keyset Self Test

The XTS-IP contains a test mode feature that supports off-line testing of digital keysets and DSS
units. The term off-line means that the unit under test cannot receive calls from the switch
during the test operation. Keysets not under test continue to operate in the normal manner.
Tests are provided to verify the keyset and DSS LED, LCD, and keyboard button operations.
1. Enter the test mode by lifting a keyset's handset to establish an off hook condition.
2. Press the SPEED button and dial [7#] on the dial pad. This disconnects the keyset from the
system and brings up the Test Mode Menu on the keyset's LCD.
3. Exit Test Mode by placing the handset on hook to reconnect the keyset to the system.
Test Mode Menu -- The menu allows the operator to select a test mode by pressing the mode
number at the dial pad. The operator can always return to the main test menu by pressing [##].

Keyset LCD/LED Test

The set of strings consists of the letters A through X and a through x. The next set of strings are:
The strings are alternately displayed on lines 1 and 2 of the LCD display.
