5. Run a maintenance session to ensure the I-ATA is not disabled. Refer 
to Port/DN status on page 308.
Calls cannot be answered (or dial tone is not 
present when making calls)
1. Check that the I-ATA connections have been made correctly.
2. Replace the analog device with a single-line analog telephone and 
check for dial tone.
3. Ensure that the analog device is not faulty by connecting it directly to 
an external line and checking for dial tone.
4. Check that the I-ATA is not busy by making a call to it from a 
telephone. If it is busy, remove the analog device and check for busy.
5. Check the internal wiring at the modular jack and the distribution 
cross-connect. The I-ATA port should have about 31 Vdc across the 
Tip and Ring when the telephone is disconnected. The voltage should 
drop when the analog telephone is connected and a call  is attempted.
6. Check the requirements of the analog device to see if it is compatible 
with the I-ATA specifications. Refer to Specifications on page 343.
Calls cannot be made (but dial tone is present)
1. Ensure that the analog device is not faulty by connecting it directly to 
an external line and making a call.
2. Ensure the dialed number is not restricted by call restrictions.
3. Check if the ICS is detecting dialing by listening to the dial tone. Dial 
the first digit of an internal telephone DN and check that dial tone is 
removed. If you still hear dial tone, the ICS is not detecting the dialed 
digit.
4. Determine if the problem is associated with the wiring by connecting 
the analog device directly at the modular jack or the distribution cross-
connect by the ICS. If calls can be made with this connection, the 
problem may be with the internal wiring.

Problems with optional 
equipment
Auxiliary ringer
1. If the auxiliary ringer is used for Schedules (Night, Evening, or Lunch 
schedule), ensure that Schedules is activated from the control 
telephone.
2. Check the wiring between the auxiliary ringer generator and the 
ringing device. Refer to the auxiliary ringer wiring chart.
3. Check the wiring between the auxiliary ringer generator and the 
distribution block.

4. Ensure that the auxiliary ringer contacts are operating properly by 
checking with an ohmmeter across the auxiliary ringer pin contacts. 
Refer to the auxiliary ringer wiring chart.
5. Check that the auxiliary ringer pin contacts are programmed to operate 
in conjunction with any or all of the features in the auxiliary ringer 
programming chart.

The maximum current carrying capability of the Norstar auxiliary relay 
contacts is 50 mA dc. They are designed to operate with the auxiliary ringer 
generator, or equivalent.

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.
KIM not working
The key interface module (KIM) that attaches to a T7316E telephone to 
create a central answer position (CAP) can be reset in two ways.
If you want to maintain the programming, you can warm start the 
module by physically unplugging the module from the telephone. 
When plugged back in, the module will perform a startup. Try this first  
when you receive an 
Addon error message on the telephone display.
If you want to restart the module and erase the programming, you can 
perform one of two cold starts described below.
Coldstarting the KIM
If the KIM does not recover after a warm reset, or if you want to reset the 
programming for the KIM, there are two types of cold starts for the 
modules:
For both types of coldstarts:
1. Unplug and replug the T7316E line cable.
The telephone restarts and all the icons flash. 
When the telephone icons stop flashing, the KIM module icons start 
flashing. 
2. When the KIM icons start flashing, select and perform the appropriate  
coldstart procedure, as described below: 
						

							286 / Problems with optional equipment
Compact ICS 6.1 Installer GuideP0603539  02
• KIM single-module coldstart
If you just want to coldstart an 
individual module:
While the reset icons are still flashing, 
simultaneously press the two top and 
two bottom buttons on the lower button 
set. 
The KIM displays a random pattern of 
icons as the KIM resets.
KIM multi-module coldstart
If you want to coldstart all the KIMs 
attached to your telephone:
While the rest icons are still flashing, 
on the first KIM, press the top two 
buttons on the upper button set, and 
the bottom two buttons on the lower 
button set
The KIM displays a random pattern of 
icons as the KIM resets.

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 292.
Refer to the Installation chapter for information about replacing 
components. 
						

							288 / Problems with BRI service

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. BRI Card indicators

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.
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.
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.
