Troubleshooting
The following sections describe some basic troubleshooting 
techniques to try with a malfunctioning portable telephone or 
base station.
Problems with a portable telephone
1. Verify that the portable is compatible with the software 
version.
2. Verify that the portable is ON and that the battery is not 
low, by checking the power indicator on the portable.
3. If no dial tone is present:
a. Verify that the dialtone is available from the ICS.
b. The portable may not be registered. Try to register the 
portable refer to the Modular ICS Companion System 
Coordinator Guide.
4. Check that the portable is using the correct registration 
slot.
5. Verify that the portable has been assigned the correct 
internal number by calling it from another telephone.
Problems with a base station
1. Verify that the green light is ON.
2. Verify that the red light is not solid.
A solid red light indicates that both radios on the 
Companion base station are busy, that the ICS is 
downloading data to the base stations, or that one or both 
radios have not been assigned to a cell.

Modular ICS Companion Installer Guide P0992639 01
3. Verify that the red light is not flashing.
The red light flashes for about 15 seconds when a base 
station powers up. This is normal. If the red light continues 
to flash, one of the problems may have occurred:
The ICS or Station Module is not ON.
The base station is not connected to the ICS or Station 
Module.
The wiring to the base station is not correct.
The TCM wiring length between the base station and 
the ICS or Station Module exceeds 1200 m.
There is a faulty ICS, Station Module, or RPI.
The two-way DC loop resistance of the power pairs 
between the Remote Power Interconnect (RPI) and the 
base station exceeds 75 ohms. Measure the loop 
resistance with an ohmmeter. If the resistance exceeds 
75 ohms, install a second power pair, or power the base 
station with a plug-top power supply.
The base station is faulty.
4. Verify that the power cord of the RPI is properly connected 
to a working AC outlet. If the base station is powered 
locally, verify that the power supply is properly connected 
to a working AC outlet and that the power supply cable is 
properly connected to the base station power connector
5. If an external antenna is installed, verify that the external 
antenna coaxial cable is properly connected to the BNC 
connector of the base station and that the corresponding 
radio is programmed to have an external antenna (see 
Installing external antenna and lightning surge arrestor 
procedures for the United States of America on page 37).
Note:  Ensure there are not any bridge taps on the TCM.

Replacing a base station
To replace a base station, you do not have to power down the 
ICS. When you replace a base station, no portable registration 
information is lost. After a short boot sequence, the base 
station should be functioning normally.
To replace a base station, follow these steps:
1. If the base station is powered locally, unplug the power 
supply from the AC outlet and unplug the power supply 
connector from the base station
2. Remove the cover from the base station mounting bracket.
3. If an external antenna is installed, unplug its coaxial cable 
from the base station.
4. Unplug the teledapt cable from the base station.
5. While holding the base station, to prevent it from falling, 
apply upward pressure to the base station.
6. Lift the base station away from the bracket.
7. Carefully install the new base station onto the bracket.
8. Gently press down to snap it into position.
9. Reconnect the teledapt cable to the base station connector.
10. Reconnect the power supply connector and external 
antenna coaxial cable to the connectors from which they 
were removed.
11. If the base station is powered locally, plug the power 
supply into the AC outlet.
The red light on each base station will flash for about 
15 seconds while powering up. This is normal.

Verifying Radio Credits (U.S. only)
You need the programming template found at the front of the 
Modular ICS System Coordinator Guide.
1. Press ²¥¥ÛßßÜÝÝ 
(¥¥‚¯öìéí).
2. Press ÛßßÜÝÝ (the default Installer password).
3. Press ‘ until you reach System prgrming.
4. Press ≠ once.
5. Press ‘ until you see Companion.
6. Press ≠. The display shows 
Registration.
7. Press ‘ until the display shows 
Radio credits.
8. Press ≠ once. The display shows nnn 
Available. Press ≠ and the display shows 
nnn Total . Verify that the total number of Radio Credits 
is enough to support the system you have just installed.
Note:  The number of Radio Credits must be double the 
number of base stations you have installed. Each base 
station has two radios so each base station requires two 
credits.
Note:  As each base station is initialized the number of 
available Radio Credits will decrease accordingly.

Problems with an RPI
To troubleshoot an RPI, follow these steps:
1. Verify that the RPI is plugged into a working AC outlet.
2. Verify that all the connections to the RPI, including the 
power cord, jumper lead, input and output, and so on, t are 
correct and secured.
3. Verify the power supply:
Verify the power cord fuse.
Verify the green internal RPI light is on.
Verify the base station green light is on.
Verify that the red light is not solid. A solid red light 
indicates that both radios on the base station are busy, 
that the ICS is downloading data into the base stations, 
or that one or both radios have not been assigned to a 
cell.
Verify that the red light is not flashing.The red light 
flashes for about 15 seconds when a base station is 
powered up. This is normal.
4. If none of the base stations connected to the RPI , or to one 
of its power supply units, is functioning correctly, replace 
the RPI or power supply unit. 
Tip - The left power supply unit provides power through 
output connectors OK1 to OK8 or OBIX1 to OBIX8, and 
the right power supply unit provides power through OK9 
to OK16 or OBIX9 to OBIX16.
If only one or a few of the base stations seem faulty,

Problems with wireless communication
Obtaining a Recovery Key 
A disabled Norstar Companion system implies that base 
stations and portables are not operational. UTAM registering 
information is, however, retained. 
To reactivate Norstar Companion communication on a 
disabled system, you require a UTAM Recovery Key. To 
obtain and enter the Recovery Key, follow the procedures for 
the UTAM Activation Key explained in Software keys (U.S. 
only) on page 67.
Obtaining a Regression Key (U.S. only)
You may need a Regression Key if one of the following 
conditions occurs:
a defective ICS is replaced
an ICS has lost its System Identification Number (SysID) 
due to a power outage for more than 72 hours
(U.S. only) If you are relocating a base station, 
call the Nortel Networks Customer Response 
Center at 
1-800-321-2649 to verify that you have 
approval from UTAM Inc. Please have your 
System ID number ready when you call.
Taking a base station out of service causes radio 
coverage to degrade. 
						

							Troubleshooting / 101
P0992639 01 Modular ICS Companion Installer Guide
If you need a Regression Key, follow these steps:
1. Record the new System Identification Number once the 
system is powered up. See Step 2: Obtain the System 
Identification Number on page 69 for more information.
2. Locate the following information in the MICS-XC 
Programming Record.
the original SysID
all previously entered radio and portable credit keys
3. Call Nortel Networks Customer Response Center at 
1-800-321-2649 to request a Regression Key. 
4. Provide them with the original and new SysID, 
Companion ID, customer address and zip code. See 
Software keys (U.S. only) on page 67.
5. Make a note of the new Regression Key.
A Regression Key cannot be reused. Please do not record 
this Key in the Programming Record.
6. Enter the Regression Key. Follow the same procedure for 
entering software keys on page 69.
Once the keys have been entered, the previous SysID is 
restored.
7. Re-enter all radio and portable credit keys recorded in 
Programming Record.
8. Verify that the correct number of Radio Credits is 
available. Refer toVerifying Radio Credits (U.S. only) on 
page 98.
9. Re-enter all programming data using information from the 
Programming Record.
10. Reregister all portables.
