Troubleshooting
When there is a problem with a portable, follow these steps:
1. Make sure the portable is compatible with the Norstar 
software version.
2. Verify that the portable is ON and that the battery is not 
low.
3. Establish a radio connection to get a dial tone.
If no dial tone is present:
Verify that dial tone is available from the ICS.
The portable may not be registered. Try to register the 
portable again. For more information, refer to the 
Registering individual portables on page 12.
Check that the portable is using the correct registration 
slot.
Verify that the portable has been assigned the correct 
internal number by calling it from another telephone.

Glossary
A
Answer button: A telephone 
button with an indicator that is used 
to monitor another telephone. The 
answer button indicates incoming 
calls destined for the other 
telephone. Someone working at a 
telephone with answer buttons (an 
attendant, for example) can receive 
all ringing and visual indication of 
incoming calls for other telephones, 
and answer those calls when 
necessary.
One telephone can have up to four 
Answer buttons. An Answer button 
is automatically assigned to a 
telephone when that telephone is 
assigned an Answer DN.
Answer DN: The internal or 
directory number (DN) of a 
telephone that is monitored by an 
Answer button. You can assign up 
to four Answer DNs to a telephone 
under Line Access in Terminals and 
Sets programming.
B
Base Station: A Companion 
component that is mounted on walls 
and ceilings to provide a radio link 
to an office or other area where 
Companion portable telephones are 
used. Each Base Station houses two 
radios that allow portables to send 
and receive calls through the ICS.
See also UTAM.
C
Call Forward: A feature that 
forwards all the calls arriving at 
your telephone to another telephone 
in your Norstar system. To have 
calls forwarded outside the system, 
use Line Redirection.
Call Park: A feature that allows 
you to place a call on hold so that 
someone can retrieve it from any 
other telephone in the Norstar 
system by selecting an internal line 
and entering a retrieval code. The 
retrieval code appears on the display 
of your telephone when you park the 
call. You can park up to twenty-five 
calls on the system at one time.
Cell: The area covered by one or 
more radios in close proximity 
within a Norstar Companion 
system. Calls on portable 
telephones are passed from one cell 
to another as the user moves around 
the office.
Companion: The name for 
Northern Telecom communication 
systems which use radio technology 
to transmit and receive signals 
between its components and the 
Norstar system.
Companion Wireless provides 
mobility in the workplace. Calls that 
used to ring just at your Norstar set 
can also appear and ring at your 
portable.

Companion ID: An eight character 
(alphanumeric) number assigned by 
Northern Telecom to identify each 
Companion wireless system. This

each time codes or credits are 
obtained using the Northern 
Telecom Customer Response 
Center.
Companion portable telephone: 
Hand-held wireless telephone

Default DN assignments start at 21 
in a two-digit (non-expanded) 
system and 221 in a three-digit 
(expanded) system.
DN: See Directory number.

component in the Norstar system. 
The ICS has its own processor and

point of connection for the various 
types of devices, telephones, and 
expansion modules used in Norstar.
The ICS can function on its own as 
a basic system (with 32 Norstar 
telephones and up to 48 external 
lines), or with the addition of Trunk 
Modules (TM) that supports more 
external lines, or Station Modules 
(SM) that support more Norstar 
telephones.
Integrated Services Digital Network 
(ISDN): A digital telephone service 
that allows for a combination voice 
and data connection over a single, 
high-speed connection. ISDN 
service can operate over the same

customer service representative.
M
M7310 telephone: A telephone that 
has a two-line display, three display

with a Busy Lamp Field.
M7324 telephone: A telephone 
with a two-line display, three 
display buttons, and 24 
programmable memory buttons 
with indicators. An M7324 
telephone can be equipped with a 
CAP module.
P
Portable Credits (U.S. only): 
Predefine the maximum number of 
portables that can be registered to the system. Systems can only 
register as many portables as there 
are available Portable Credits.To 
register additional portables, you 
must obtain Portable Credit Codes 
for the number of additional 
portables you need.You can obtain 
additional codes whenever you need 
to expand the number of portables, 
up to a maximum of 60 portables for 
each XC system. 
portable telephone: See 
Companion portable telephone.
Prime line: A line on your 
telephone that is automatically 
selected when you lift the receiver, 
press the Handsfree/Mute button or 
use an external dialing feature. A 
Prime line is assigned to a telephone 
by your customer service 
representative.
programming: A series of 
procedures that set the way the 
Norstar system works. 
Programming includes system-wide 
settings and individual telephone 
and line settings.
programming overlay: A paper 
template that is placed over the top 
four memory buttons with 
indicators on the M7310 or M7324 
telephone during programming. The 
overlay labels indicate the special 
function that each of the four 
buttons takes on during 
programming. The overlay is found 
at the front of this guide.
