External paging
1. Use the Button Inquiry feature (²¥â) to verify the feature of a 
programmable memory button.
2. Check the wiring between the 50-pin connector and the paging 
amplifier or between the connections shown in the external paging 
wiring chart.
External paging wiring
3. Test external paging ²ßÛ to ensure that it is working. The 
nominal output signal from the Norstar ICS is 100 mV rms across  
600 Ω.
Music on Hold/Background Music trouble
Although Music on Hold and Background Music are separate features, they 
share the same wiring and customer-supplied music source.
1. Ensure that the proper feature access code (
²¡ß) is turned on. 
Adjust the volume using the volume control  bar.
2. Use the Button Inquiry feature (
²¥â) to verify the feature on a 
programmable memory button.
3. If there is trouble with Music on Hold, check the music settings in 
programming.

4. Check the wiring between the music source and the 50-pin connector. 
See the wiring charts in the Installation section.
5. Ensure that the music source is turned on, is operational, and the 
volume control is set properly.
6. Any music source with a low-output impedance (for example, less 
than 3,300 ohms) can be connected. The output level must be less than 
one volt. 
						

							Problems with Trunk Cartridges / 273
P0992669 03Compact ICS 6.0 Installer Guide
Problems with Trunk Cartridges
Check first for user configuration problems, then wiring and programming 
errors before replacing Norstar equipment.
Trunk Cartridge trouble
1. Check that the cartridge is properly inserted in the ICS.
2. Run a Maintenance session to ensure that the cartridge is not disabled.
If the problem persists:
1. If AC power is present and the LED indicator on the ICS is off, see the 
section on ICS down on page 278.
Refer to the Installation chapter for information about replacing 
components. 
						

							274 / Problems with BRI service
Compact ICS 6.0 Installer GuideP0992669 03
Problems with BRI service
Each LED on front of a BRI-ST or BRI-U Card corresponds with a loop, 
or indicates an overall state of the BRI connections.
The BRI card is connected to the ISDN network 
(U-loop) but the LED for one of more loops is not lit
Possible problem
The physical connection or configuration  for the network  connection is not 
correct (no Layer 1).
Solution
1. Verify the wiring from the network to the distribution block.
2. Verify the wiring from the distribution block to the ICS.
3. Use a Meridian 2500 set to test for data on the BRI trunk.
4. Test the network connection by connecting Bellcore standard terminal 
equipment (TE) directly to the network.
5. Verify that the loop is provisioned.
6. Verify that the loop is properly configured, including the proper loop 
type, SPIDs, and Network DNs.
7. Disable and re-enable the BRI Card.
8. Disable and enable the module for the Card. BRI Card indicators

“Out of service” is displayed when a BRI line is 
selected (LED for loop is lit)
Possible problem
The loop is configured incorrectly. Layer 1 is present but Layers 2 and 3 
are not working.
Solution
1. Verify that the SPIDs and Network DNs are programmed correctly in 
Hardware.
2. Verify that the loop and lines are provisioned.
All the LEDs on a BRI Card are flashing
Possible problem
The card is not configured properly.
Solution
1. Verify that the loop is properly configured, including the proper loop 
type, SPIDs, and Network DNs.
Possible problem
The card is not recognized by the ICS.
Solution
1. Verify that an Expansion Cartridge with Clocking, or Clocking 
Cartridge is installed in the ICS.
2. Replace the card with another card of the same type. 
						

							276 / Problems with BRI service

Caller hears one ring and then a fast busy signal 
when placing a call on a BRI line
Possible problem
CACH or EKTS, which are not supported by Compact ICS, is included in 
the ISDN services package.
Solution
1. Contact your service provider and ensure that CACH or EKTS are not 
part of the ISDN services package. These services must be turned off 
at the switch.
2. Verify that the Network DNs have been programmed correctly, and 
verify the numbers with your service provider.

Problems with the NT1
The table gives the meaning of the indicators found on the stand alone NT1 
manufactured by Nortel. Other models or makes of NT1 may have different

							278 / ICS down
Compact ICS 6.0 Installer GuideP0992669 03
ICS down
If AC power is present and the indicator light on the ICS is off, replace the 
fuse in the ICS (see illustration on next page). 
1. Disconnect all central office and station lines from the ICS. Power 
down the ICS by unplugging it.
2. After powering down the ICS, use fingernails or screwdrivers to pinch 
the tabs on the fuse drawer and remove it from the ICS. The cables can 
easily and safely be pushed aside to reach the fuse drawer.
3. Remove the fuse from the left-hand compartment and discard. This is 
NOT the one labeled spare fuse.
4. Insert the new fuse into the left-hand compartment.
5. A spare fuse is located in the right-hand compartment of the fuse 
drawer. This fuse is labeled as a spare fuse.
6. If there is no spare fuse, you will have to obtain a replacement. 
 
7. Replace the fuse drawer in the ICS and restore power to the system.
8. Connect the central office and station line connectors.
Your Norstar system requires connection to a 
grounded outlet.
To prevent possible injury from voltage on the 
telephone network, disconnect all central office and 
station lines before removing plug from the electrical 
outlet.
Replace with the same type of fuse.
For continued protection against risk of fire, replace 
only with the same type and rating of fuse (250 V, 
3.15 A).

							280 / Problems for network or remote users
Compact ICS 6.0 Installer GuideP0992669 03
Problems for network or remote users
Remote feature code gets no response
Possible problem
A Norstar user has called into another Norstar system and is trying to 
activate a remote feature but gets no response after dialing the feature code.
Solution
1. If a COS password is needed for remote access, make sure the user has 
entered the appropriate password.
2. Make sure that the remote caller is dialing the feature code correctly. 
Use the asterisk (*) character, followed by the feature code, to activate 
a remote feature. 
Do not use 
² for accessing features on a remote Norstar system.
3. Ensure that the remote user is dialing tones, not pulses once the call is 
answered.
4. Make sure an appropriate remote package is in use for the incoming 
line.
5. Check the restrictions for the remote package used with the incoming 
line.
Dialed number gets ringback and the wrong person
Possible problem
The digits sent by a switch at a central office or in the private network did 
not match any Received number, the Auto DN, or the DISA DN. The call 
has been routed to the prime telephone for the incoming trunk.
Solution
1. Verify that the switch is sending the correct number of digits for the 
Received number length defined in your system.
2. Verify all the digit strings that the switch should be sending.
