Automatic Call Back 
If you call a number and it is busy, enter the appropriate 
feature code designated by your service provider to receive a 
distinctive ring at your set when the line becomes available for 
calls.
Automatic Recall
Automatic Recall allows you to automatically dial the number 
of the last call you received. You may not see the number on 
the display if the information is not available from your service

provider, or if you do not have Caller ID as part of your ISDN 
service.
Consult your service provider for the appropriate feature code 
to enter on your dialpad.
MCID (profile 2)
The MCID feature allows you to enter ²¡áà to have 
call information recorded on the central office system for an 
incoming call on a specific line (ETSI EURO ISDN lines, 
only).
The user must invoke the feature code either during the active 
call or within 30 seconds (time varies on different networks) 
after the caller hangs up, but before the user hangs up.
MCID prompts
The MCID request was accepted by the 
network.
No response to the MCID request.
MCID can only be invoked on received 
calls.
The caller information is not  available. The 
CO is not  able to log the information or  it is 
not an ETSI BRI/PRI type of call.
MCID feature is not subscribed to.
MCID is not allowed in the current state of 
the call.
Invalid interaction with another 
supplementary service.

Network Call Diversion (profile 2)
This feature is a network function that allows forwarding and 
redirection of calls outside the Norstar network when using an 
ETSI ISDN line. Functionality is similar to that of External 
Call Forward (ECF). NCD redirects calls using the same line 
on which they arrive. Call forward is efficient since there is no 
need for additional outside lines.
Overlap dialing (profile 2)
This feature allows a break in the dialing sequence when 
dialing on ETSI PRI lines that require overlap dialing.
ISDN BRI terminals
Your Modular ICS allows connection of eight Basic Rate 
Access loops (four 2B+D channels) that can be used for fully 
digital connections to ISDN networks and devices. Loops are 
connections between the ICS and devices or between the ICS 
and the network.
Each loop provides two separate B-channels that can be used 
to make two simultaneous voice or data calls, or one data call 
and one voice call.
ISDN applications for BRI and PRI
ISDN terminal equipment delivers a wide range of powerful 
business applications:
Videoconferencing and video telephony
Video conferencing offers instant visual and audio contact 
between distant parties using either studio-based or desktop 
ISDN terminals. 
						

							214 / ISDN PRI and BRI
Modular ICS 6.1 System Coordinator Guide P0603535  02
Desktop conferencing
ISDN allows computer users in distant locations to share and 
edit any image, data or text file on their own computer screens 
while they discuss the information.
File transfer
The ISDN network allows you to transfer files containing data, 
text, images, data, or audio clips, faster and cheaper than with 
a conventional modem.
Telecommuting
Convenient retrieval, processing and storage of files is 
possible for the employee working at home by using ISDN 
lines to give high-speed access to information resources at the 
office.
Group 4 fax
ISDN fax applications save money by increasing both 
transmission speed and the quality of resolution.
Remote LAN access
ISDN provides an affordable and fast means for employees at 
remote sites (at home or branch offices) to access local area 
networks (LANs).
Leased line backup
Essential backup for leased lines can be provided using ISDN 
as required, rather than duplicating costly permanent leased 
lines.

LAN to LAN bridging
Local area network (LAN) bridge/routers allow flexible 
interconnection between LANs using ISDN, with charges 
incurred only when information is actually transmitted.
Internet and database access
The fast call set up and high bandwidth of ISDN are ideal for 
accessing information services such as the  Internet and 
databases.

Using System features
Using alternate or scheduled services
There are three types of Services to make your Norstar system 
handle calls differently on different days and at different times 
of the day: Ringing service, Restriction service and Routing 
service.
Each of the three services, and the six schedules available to 
each service, are customized for you by your installer or 
customer service representative. They program which 
telephone is used to turn Services on and off, and display what 
Services are in use. This is called the control telephone.
Preventing certain calls from being made
Restriction service prevents a user from making certain kinds 
of calls from a telephone or from lines that are available at the 
telephone. The restrictions are programmed by your installer 
or customer service representative. For example, you might 
want to restrict long distance dialing between certain hours of 
the day.
Making additional telephones ring
Ringing service makes additional telephones ring for 
incoming calls on external lines. For example, all incoming 
external calls can ring at a security telephone during the night. 
Or calls to one attendant can ring at another telephone during 
lunch. This service does not suppress your normal ringing 
assignment.

Changing the lines used by outgoing calls
Routing service allows you to assign alternate routes to calls 
during different schedules. In this way you can take advantage 
of lower costs available on particular routes on certain days 
and at certain times. Both the regular and alternate routes are 
programmed by your installer or customer service 
representative.
Note: Your system administrator can also assign alternate 
routes for destination codes that are defined to run on a 
schedule. In this case, alternate routes are offered only in the 
case where the original route is not available. Refer to the 
section on least-cost routing in the Modular ICS Installer 
Guide.
Turning Services on and off
The master control for how different services and their 
schedules are used by your system is in programming. There 
are three settings: Manual, Automatic and Off.
Manual allows you to turn the service on and off at any 
time from a control telephone using a feature code.
Automatic allows you to use the preassigned stop and start 
time for a service. You are able to start and stop the service 
by entering the appropriate feature code at a control 
telephone. If you select this setting, you use the start and 
stop times programmed by your installer or customer 
service representative. 
Off prevents the service from being activated.
In the case of restriction settings and routing, this means 
that the Normal schedule will be in effect.

You need the programming template found at the front of this 
guide. See Getting started with Norstar on page 13 for more 
information.
1. Press ²¥¥ÛßßÜÝÝ.
2. Press ÛÜßÝß (the default System Coordinator 
password).
3. Press ‘ twice. Services displays
4. Press ≠. Ringing Service displays.
5. Press ‘ until you see the service you want to 
program.
6. Press ≠ and ‘ until you see the 
schedule you want to program.
7. Press ≠ and use CHANGE
 to select the setting that 
works best for your office: Off, Manual or Automatic.
Each schedule can have its own configuration of a Service 
which works independently of automatic start and stop times. 
For example, there may be a version of Restriction service 
called Night Schedule that prevents anyone from making long 
distance calls. But calling it Night Schedule does not mean it 
can only be used with a schedule. You can turn the Night 
Schedule for Restriction Service on or off, as needed, any time 
of the day or night. If you decide to run a service on a schedule, 
the system uses the start and stop times used for that schedule.
An example of how to turn on a Service manually
You may have Ringing service, as your night service, set up to 
run according to the Night Schedule. You may decide you 
want that ringing arrangement to come into effect only when it 
is turned on and off manually.
