Norstar telephone dead
1. Run a Station Set Test (²¡âÞ). Instructions are included in 
the Compact ICS 6.0 System Coordinator Guide.
2. If more than one telephone is affected, refer to the ICS down section 
on page 278.
3. Check for dial tone.
4. Check the display.
5. If the problem persists, replace the telephone with a known working 
Norstar telephone of the same type, so that the programming is 
retained.
6. Check the internal wiring at both the modular jack and the distribution 
cross-connect. A Norstar telephone port should have between 15 and 
26 V DC across the Tip and Ring when the telephone is disconnected.
7. Check the line cord.
Running a Maintenance session to test a dead telephone
1. Run a Maintenance session to ensure that the telephone is not disabled. 
See Port/DN status on page 294.
2. Disable the port that the telephone is connected to using the heading
 
Port/DN status.
3. Enable the port that the telephone is connected to using the heading
 
Port/DN status.
Replacing a telephone
In a powered-up system, an existing Norstar telephone can be replaced by 
a new Norstar telephone. If you use a Norstar telephone that has already 
been used on the system, it may have to be reprogrammed.
Replacing Norstar telephones of the same type
If an existing Norstar telephone is unplugged, and a new Norstar telephone 
of the same type is then plugged into the same jack (for example, replacing 
an T7208 telephone with another T7208 telephone), the new telephone 
acquires the programming and the internal number of the old telephone. 
This is normally done to replace a defective telephone.

Replacing Norstar telephones of different types
If an existing Norstar telephone is unplugged, and a new Norstar telephone 
of a different type is plugged into the same jack (for example, replacing an 
T7208 telephone with an T7316 telephone), the new telephone keeps the 
old internal number. The new telephone receives default programming for 
a telephone of its type. 
If the telephone being replaced has more lines than the new telephone, 
automatic outgoing line selection may not work with the Handsfree/Mute 
feature. A line must be selected manually.
Status of a telephone that was replaced
The old Norstar telephone that was unplugged and replaced by a new 
Norstar telephone loses its programming and internal number. The old 
telephone internal number has been given to the new telephone and the 
programming has either been removed or given to the new telephone when 
it was plugged into the old jack. The replaced telephone (if still functional) 
is now treated by the system as a telephone not previously in service.
Emergency telephone dead
1. Verify that the power indicator on the ICS is not lit.
2. Verify that there is no dial tone at the emergency telephone.
3. Check that  the external line and  emergency  telephone connections 
have been made correctly.
4. Ensure that the emergency telephone is not faulty by connecting it 
directly to the external line 002 and listening for dial tone.
5. Verify that the ICS has a Loop Start Trunk Cartridge installed. 
6. Verify that there is dial tone on line 002 of the ICS.
7. Replace the ICS.

Hung lines at a telephone
Line indicators that have been solid for a long time are the only visible 
indication that lines are hung. 
Possible problem
A line that has been redirected using Line Redirection may, under some 
circumstances, remain busy after a call is over. If this happens, the 
outgoing line for the redirection also remains busy. You can clear this kind 
of hung line only at the telephone that was used to redirect the line. 
Solution
1. Enter the Button Inquiry feature code (²¥â) at the telephone 
that was used to redirect the line. 
2. Press the button of the redirected line.
3. Press 
SHOW or £.
4. Press 
DROP or •. 
Both the redirected line and the outgoing line for the redirection should 
now be cleared.

Solution
Verify that your programming for the line matches the central office 
settings.
Possible problem
Lines are still hung after all the above solutions have been investigated or 
tried out.
Solution
For lines that are hung for any other reason, you will have to run a 
Maintenance session. 
1. Run a Maintenance session and go to the heading
 Module status.
2. Disable and enable the affected Trunk Cartridge. 
Follow the procedures in the Troubleshooting overview and the Installation 
check sections before proceeding.
Auto-answer line rings at a Norstar telephone
Possible problem
You configured a loop start trunk as auto-answer but the installed hardware 
does not support disconnect supervision. (In this case, the symptom would 
be accompanied by the Alarm 62 code symptom.)
Solution
Reconfigure the trunk as manual answer.
OR
Replace the Trunk Cartridge with one that provides disconnect 
supervision.

Trunk/Line data does not match the setting for the line at the central office.
Solution
Reconfigure the Discon timer to match the setting at the central office.
Prime telephone gets misdialed calls
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.

Solution
Enable the line.
OR
If the line will be out of service for some time, configure another line to 
replace it on the telephone.
Selected line pool shows ‘No free lines’ 
Possible problem
If this happens often, there are not enough lines in the line pool to serve the 
number of line pool users.
Solution
Enter programming and move less-used loop start trunks from other line 
pools into the deficient line pool. 
						

							268 / Problems with the I-ATA
Compact ICS 6.0 Installer GuideP0992669 03
Problems with the I-ATA
The problems listed here focus on trouble with the I-ATA and the analog 
device connected to it.
Calls do not ring and caller does not receive busy tone
1. Verify that the ringer of the attached analog device is turned on.
2. Check the ringer volume.
3. Verify that calls can be answered even when the device does not ring.
4. Replace the analog device with a single-line analog telephone and 
check for ringing.
5. Check for ringing at the wiring connection block using a single-line 
analog telephone.
6. Check wiring from the connection block to the attached analog device.
7. Check the requirements of the analog device to see if it is compatible 
with the I-ATA specifications (see specifications on page 329).
I-ATA is always busy
1. Remove the attached analog device from the I-ATA line and make a 
call to the I-ATA from a Norstar telephone. If the line is not busy, the 
analog device may be faulty. If the line is busy, check the wiring.
2. Ensure that the analog device is not faulty by connecting it directly to 
an external line and verifying that it functions correctly.
3. 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.
4. Check the requirements of the analog device to see if it is compatible 
with the I-ATA specifications. Refer to Specifications on page 329.
5. Run a maintenance session to ensure the I-ATA is not disabled. Refer 
to Port/DN status on page 294. 
						

							Problems with the I-ATA / 269
P0992669 03Compact ICS 6.0 Installer Guide
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 Norstar 
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 329.
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.
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 329.
