Headset Installation
TheXTSElectronic/Digital Key Telephones have been designed to operate with industry
standard electret mic compatible modular headset adapters and operator headsets.
To modify an Electronic/Digital Key Telephone to support an external headset:
1. Plug the headset adapter cord into the vacant handset jack on the Key Telephone base.
2. Plug the telephone handset cord into the headset adapter box where indicated by the
headset manufacturers instructions.
The Headset Operation must be enabled (refer toStation Programming). The station then has
the capability to enable/disable headset mode by dialing a code. When Headset mode is
active at the station, the ON/OFF button controls the on-hook or off-hook status. Also,
features such as on-hook dialing and handsfree speakerphone operation become inoperable.
Caller ID Interface Unit Installation
The Caller Identification Interface Unit receives the data from the telephone company and
sends the data, in ASCII RS-232C format to a printer, telephone, computer or DTE (Data
Terminal Equipment) device.
Selecting the Cable
1. SelectthecorrectcablefortheMPBandSIU.
†To connect a 1480-00 caller ID box to the SMC1 connector of the MPB or to the SIU,
use cable P/N 9081-01.
†To connect a 7480-00 caller ID box to the SMC1 connector of the MPB or to the SIU,
use the flat ribbon cable supplied and the 7481-10 adapter kit.
2. Connect one end of the cable on the desired KSU I/O port (1, 3, 4, or 5).
3. Connect the other end to the OUT port on the Caller ID unit. Use the adapter as necessary.

Maintenance and
Troubleshooting
This chapter is provided as a guideline in isolating and resolving functional problems
that may be encountered as a result of improper use or component failure of theXTS.
Other failures, such as no dial tone from the central office, must also be considered as
an overall troubleshooting procedure.

							System & Database Check4-3
Chapter 4 - Maintenance and Troubleshooting
System & Database Check
System operation should be verified as per the programmed customer database once all
customer database programming has been completed. A hard copy of the customer database
can be printed from the system and should be kept on-site and up to date for future reference.
TheXTSSystems are highly featured digital switches and as such, feature activation can
sometimes be mistaken for improper operation.
Preliminary Verification
1. First, verify all programmable features are enabled for the phone or function in question.
2. Then compare the suspected improper operation with the feature operation description
to determine which feature is causing conflict.
Be aware that some features can override others and take precedence in operational priority.
3. Then make the necessary programming changes in customer database programming to
acquire the desired operation.
General Troubleshooting
If feature operation is not the cause of the suspected problem, then general troubleshooting
procedures should be employed. A basic guideline for determining the cause of a reported
problem are as follows:
1. Verify that system programming is correct and that the suspected feature, circuit or
function has been enabled in programming.
2. Check the unit on another circuit, if possible, and verify that it is functioning.
3. Check the installation cabling/wiring and connectors for cuts, shorts, or loose
connections.
4. Check the system interface circuit by substituting a known good circuit. Verify the
Service/Normal switch on the printed circuit board is in theNORMALposition.
By verifying correct operation for each segment of the installation and system, the source
of the problem is isolated and can be identified and resolved.
The system must be initializedbeforethe Customer Database is programmed. 
						

							4-4Telephone Troubleshooting
Chapter 4 - Maintenance and Troubleshooting
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
TheXTScontains 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’sLCD.
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
This test outputs a series of continuously repeated LCD string messages to LCD lines 1 and 2.
The set of strings consists of the lettersAthroughXandathroughx.Thenextsetofstringsare:
The strings are alternately displayed on lines 1 and 2 of the LCD display.
Keyset Button Test
1. Press a keyset button to turn on the LED and display an LCD message identifying the
button number.
Each time the selected button is pressed it sequences through the flash rates available.

2. PressthedialpadkeystodisplayanLCDmessagethatindicateswhichdigitwaspressed.
Depressing the H-T-P switch from one position to another displays one the following
words: H_POS, T_POS, or P_POS.
3. Test LEDs independently of the Keys by pressing the flexible LED button.
DSS LED/Button Test
When the DSS test is selected and a DSS test is invoked, ALL DSS units associated with the
keyset are placed in the test mode.
If no DSS unit is associated with the keyset, the keyset display indicates NO DSS. The DSS LED
test causes all the LEDs to light steady. All LEDs remain lit steady until a DSS flexible button is
depressed. Pressing a DSS button turns on the DSS button LED and displays an LCD message
on the associated keyset identifying the DSS button number (01 to 48). In addition, it turns off
the previously selected flexible LED.
Conditions
»Test Mode interrupts the normal operation of a keyset or DSS.
