Naming a telephone or a line
You can assign names to identify external lines, target lines, 
and each set. During a call, the name, if programmed, is shown 
on the telephone display instead of the external line number or 
internal telephone number of the caller. Step-by-step 
instructions for adding or changing the name of a telephone or 
a line are in Changing the name of a telephone on page 34.
Telephone names and line names can contain both letters and 
numbers, but cannot be longer than seven characters. You 
cannot use the # and * symbols.
Moving telephones
If automatic telephone relocation is enabled in programming 
by your installer or customer service representative, you can 
move your telephone from one Norstar jack to another without 
losing any of its custom programming. If you want to replace 
a telephone and cancel the programming, ensure that the 
relocation setting is off.
Tip - You can give the same name to two or more telephones, 
or to a telephone and a line in your system. To avoid confusion, 
avoid such duplication. Use initials, abbreviations, or even 
nicknames to give each telephone a unique name.
If automatic telephone relocation is turned on, the name and 
internal number of a telephone are saved if the telephone is 
moved within your system.
You may be required by law to report any telephone moves 
to your local telecommunications carrier or 911 service 
provider. For further details, consult your local carrier, your 
local 911 service provider, and/or your local 
telecommunications service provider.

Using Do Not Disturb
Once you turn Do Not Disturb on, calls are forwarded to the 
prime telephone only if there is no other telephone on which 
the line appears. If there is another telephone that shares the 
same line, the call may be answered by that person.  The 
Delayed Ring Transfer feature transfers all unanswered calls 
to the prime telephone after a specified time.
Do Not Disturb prevents voice calls from alerting at your 
telephone. Voice calls are presented as normal intercom calls.

Using Background Music
²¡ß
Use this feature to active the optional music feature. You will 
hear whatever music source is attached to the Modular ICS.
Your installer or service representative makes this feature 
available to all telephones in programming. You need to

ISDN PRI and BRI
Integrated Services Digital Network (ISDN) technology 
provides a fast, accurate and reliable means of sending and 
receiving data, image text and voice information through the 
telephone system. 
By using Primary Rate Interface (PRI) or Basic Rate Interface 
(BRI), your ISDN service allows for faster transmission 
speeds and the addition of a variety of powerful business 
applications, including remote LAN access, 
videoconferencing, file transfer and Internet access.
Your installer configures your ISDN services and terminal 
equipment. 
ISDN PRI
PRI is economical because separate analog trunks and data 
circuits are not needed for Direct Inward Dialing (DID), Direct 
Outward Dialing (DOD), and data transfer.
With PRI there is greater flexibility because B channels can be 
dynamically reconfigured to accommodate changes in traffic 
with the Call by Call feature. For more information see Call by 
Call service selection for PRI on page 198.
PRI offers fast information access because channel usage is 
optimized to allow you the full benefit of available bandwidth 
and real-time connectivity.
PRI lines are configured as DID lines. Incoming calls on a PRI 
line can appear on a DID button or on an intercom button 
depending on how your Norstar set has been configured. 
Outgoing calls are made from the intercom buttons. 
						

							196 / ISDN PRI and BRI
Modular ICS 6.0 System Coordinator Guide P0992640 03
PRI lines can be accessed from all devices such as Norstar sets, 
Business Series Terminal sets, ISDN sets, and wireless sets.
ISDN PRI features
Selected ISDN network features can be used from a Norstar 
telephone. Your central office switch (ISDN network) 
determines which features are available to you.
Network Name Display for PRI
Your Norstar system displays the name of an incoming call 
when it is available from the service provider. Name 
information can be displayed on a Norstar set but not on an 
ISDN terminal. If the Calling Party Name has the status of 
private it may be displayed as Private name. If the Calling 
Party Name is unavailable it may be displayed as Unknown 
name.
Your Norstar system displays the name of the called party on 
an outgoing call, when it is provided by your service provider.
The Business Name concatenates with the set name on an 
outgoing call. This can only occur if the Business Name has 
been programmed.
The available features include:
Receiving Connected Name
Receiving Calling Name
Receiving Redirected Name
Sending Connected Name
Sending Calling Party Name
Consult your customer service representative to determine 
which of these features is compatible with your service 
provider.

Name and number blocking for PRI
When activated, ²¡Úá allows you to block the 
outgoing name and/or number on a per-call basis. Name and 
number blocking can be used with a Norstar set but not with 
an ISDN terminal.
Consult your customer service representative to determine 
whether or not this feature is compatible with your provider.
Emergency 911 Dialing
Modular ICS 6.0 with the ISDN PRI feature is capable of 
transmitting the telephone number and internal extension 
number of a calling station dialing 911 to the Public Switched 
Telephone Network. State and local requirements for support 
of Emergency 911 Dialing service by Customer Premises 
Equipment vary. Consult your local telecommunications 
service provider regarding compliance with applicable laws 
and regulations.
If transmission of internal extension numbers is not required or 
desired, then it is recommended that the System Coordinator 
maintain a site map or location directory that allows 
emergency personnel to rapidly locate a Norstar set given its 
DID number. This list should be kept up to date and readily 
available, and can be included with the Programming Record.
Two-way DID
With PRI, the same lines can be used for receiving direct 
inward dialing (DID) and for making direct outward dialing 
(DOD) calls.
The dialing plan determines how calls are routed.
Consult your customer service representative to determine 
whether or not this feature is compatible with your service 
provider.

Call by Call service selection for PRI
PRI lines can be dynamically allocated to different service 
types with the Call by Call feature. PRI lines do not have to be 
pre-allocated to a given service type.
Call types that may be available, depending on your service 
provider are:
Consult your customer service representative to determine 
whether or not this feature is compatible with your provider.
PublicPublic calls connect your set with a Central 
Office (CO). DID and DOD calls are supported.
PrivatePrivate calls connect your  set with a private 
network. DID and DOD calls are supported. A 
private dialing plan may be used.
TieTie lines are private incoming and outgoing 
lines that connect Private Branch Exchanges 
(PBX) such as Norstar.
FXForeign Exchange calls connect your Norstar 
set to a remote CO. It provides the equivalent of 
local service at the distant exchange.
OutwatsOutwats is for outgoing calls. This allows you 
to originate calls to telephones in a specific 
geographical area called a zone or band. 
Typically a flat monthly fee is charged for this 
service.
InwatsInwats is a type of long distance service which 
allows you to receive calls originating within 
specified areas without a charge to the caller. A 
toll-free number is assigned to allow for 
reversed billing.

Dialing Plan and PRI
The Dialing Plan supports PRI connectivity to public and 
private networks. The dialing plan is a collection of features 
responsible for processing and routing incoming and outgoing 
calls. All PRI calls must go through a dialing plan.
The Dialing Plan 
allows incoming calls to be routed to sets based on service 
type and digits received
allows Enbloc dialing by buffering user-dialed digits until 
a complete DN has been dialed
provides the ability to map user-dialed digits to a service 
type on a Call by Call basis
allows long distance carrier selection via user-dialed 
Carrier Access Codes
Depending on the type of dialing plan chosen, you may also 
need to specify a Private DN length so the system knows when 
the user has completed dialing. 
Refer to the Networking chapter in the Modular ICS 6.0 
Installer Guide for more details about dialing plans. Consult 
your customer service representative to determine how your 
dialing plan is configured.
ISDN BRI
Modular ICS 6.0 supports a maximum of 30 ISDN sets on the 
system.
The following ISDN services are supported:
incoming calls
outgoing calls
Calling Line Identification Presentation 
						

							200 / ISDN PRI and BRI
Modular ICS 6.0 System Coordinator Guide P0992640 03
Sub-addressing
bearer capabilities
teleservices
The Call Forward All Calls feature can be used from ISDN 
terminals connected to Modular ICS.
Note:  Norstar and Business Series Terminal telephones can 
accept voice calls only. Video and data calls do not alert 
at a Norstar set.
Although an ISDN S-loop or LT-loop can support up to eight 
devices, the loop has a limit of two B-channels. If both B-
channels are in use, other devices on that loop cannot make or 
receive calls until a B-channel is available, or until both B-
channels are available, in the case of a video terminal. Thus, 
the number of terminals installed must take into account 
whether you require dedicated access for the terminals on that 
loop.
Note:  Set features, other than Transfer and Call Forward All 
Calls, are not available to ISDN terminals. In addition, 
you cannot retrieve a parked call, or reach a Direct-Dial 
set by using the Direct-Dial digit from an ISDN 
terminal.
Line access from an ISDN terminal
ISDN terminals do not have line keys or intercom keys as do 
Norstar telephones and Business Series Terminals. To make 
an outgoing call from an ISDN terminal, access an external 
line by entering a line pool code or by using the ARS feature.
