System Programming and Verification
System operation should be verified as per the programmed customer database once all 
customer database programming is 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.
The STS System is a highly-featured digital switch and, as such, feature activation can 
sometimes be mistaken for improper operation. First, verify all programmable features are 
enabled for the phone or function in question. 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. Then make the necessary programming changes in customer database programming 
to acquire the desired operation.
If feature operation is not the cause of the suspected problem, then general troubleshooting 
procedures should be employed. Use these basic guidelines to determine the cause of a 
reported problem:
1. Verify that system programming is correct and that the suspected feature, circuit, or 
function was enabled in programming.
2. Check the installation cabling/wiring and connectors for cuts, shorts, or loose 
connections.
By verifying correct operation for each segment of the installation and system, the source 
of the problem is isolated and can thereby be identified and resolved.
Telephone and Terminal Troubleshooting
This section discusses general functions 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).
System must be initialized before the customer database is programmed.  
						

							4-4Keyset Self Test
Chapter 4 - Maintenance and Troubleshooting
Keyset Self Test
The STARPLUS STS System 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 is operationally 
disconnected 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.

The test mode is entered by taking a keyset’s handset off hook.

Press the SPEED button and dial [7#] on the dial pad to disconnect the keyset from the 
system and bring up the Test Mode Menu on the keyset’s LCD. To exit the test mode, 
place the handset back on hook. This reconnects the keyset to the system.
Test Mode Menu -- The menu allows you to select a test mode by dialing the mode number 
at the dial pad. You 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 letters A through X, a through x, “PICKUP TRUCK SPEED ZONE!, 
and  ***STANDING BACK***”.
1st Example - First Message String
2nd Example - Second Message String
3rd Example - Third Message String
4th Example - Fourth Message String

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 fixed feature button is pressed it sequences through the table of 
flash rates available. Refer to Table 4-1: Flash Rates.
2. Press the dial pad keys to display an LCD message that indicates which digit was pressed.
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 flex 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 flex button is 
pressed. 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). This button also turns off 
the previously selected flex LED.

Remote Maintenance
General Overview
The Remote Maintenance feature allows authorized personnel to survey system, slot 
configuration information and programming. This can be done through the optional modem. 
The commands are entered from a keyboard.
Maintenance Command Format
There are four basic commands available in the Remote Maintenance feature. All commands 
begin with a single character, followed by a space, another character and an optional digit or 
digits. All commands are terminated with the  key.
Maintenance Password
The Maintenance feature, like Programming, is entered via a six-character alphanumeric string. 
The password prompt is given by pressing  at the device connected to the RS232-1 port 
(COM1) of the BKSU or connected to the modem. After the prompt displays, enter the 
password, then press . Proper entry of the password displays the maintenance prompt.
» The Maintenance password is: config
