subaddressing of terminal equipment (TE) on the same BRI loop. 
However, terminal equipment which supports sub-addressing is not 
commonly available in North America.
Transmission of B-channel packet data is not supported by Compac tICS.
Contact your ISDN service provider for more information about these 
services and features. Packages for ISDN service in North America are 
described on page 38.
The terminal equipment (TE) connected to the Norstar system can use 
some feature codes supported by the ISDN service provider. See ISDN 
services and features in the Compact ICS 6.1 System Coordinator Guide 
for more information.
Network name display
When your phone rings, this feature allows you to see the name of the 
person who is calling you. This call information is only available from the 
public network and must be activated on the public network side of the 
switch. 
Name and number blocking
This feature allows you to program a feature button with the code from the 
CO that is used to suppress the outgoing name and/or number for your 
telephone. For information about system programming of this feature, see 
Outgoing Name and Number Blocking on page 253.
MCID (ETSI system feature)
The MCID feature allows you to use ²¡áà to have call 
information recorded on the central office database for an incoming call on 
a specific line (EUROISDN lines, only).
The user must invoke the feature code without hanging up, and within 30 
seconds (time varies on different networks) after the caller hangs up.

Network Call Diversion (ETSI system feature)
This feature is a network function of ETSI E1 lines 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.
ISDN hardware
To support connections to an ISDN network and ISDN terminal 
equipment, your Compact ICS must be equipped with one or more BRI 
Cards (BRI-U or BRI-ST).
BRI Card
The loops on BRI-U and BRI-ST Cards can be programmed to support 
either network or terminal connections. This allows you to customize your 
arrangement of lines, voice terminals, data terminals and other ISDN 
equipment. This section describes some basic hardware configurations for 
network and terminal connections for each loop type.
For detailed wiring information about BRI network and terminal 
connections see Installation on page 69.
BRI-U2 and BRI-U4
A BRI-U2 Card supports two loops and the BRI-U4 supports four loops. 
Each loop can be individually programmed to provide one of the following:
a U-LT reference point connection for terminal equipment (TE) with 
built-in NT1 functionality (U interface)
a U-NT reference point connection for direct connection to an ISDN 
network
BRI-ST Card
A BRI-ST Card provides four loops. Each loop can be individually 
programmed as one of the following:
an S reference point connection (S loop) to ISDN TE
a T or S reference point connection (T loop or S loop) to an ISDN 
network using an external NT1

U-LT reference point
The U-LT reference point connection provides a point-to-point digital 
connection between Norstar and TE equipped with a U interface.
A U-LT loop supports up to eight ISDN DNs, which identify TE to the ICS.
U-NT reference points
The U-NT reference point connection provides a point-to-point digital 
connection between the ISDN network and the ICS.
A U-NT loop provides lines that can be used by all Norstar telephones, 
peripherals and applications, and ISDN TE.
U-NT and U-LT loops can be used in combination to provide D-packet 
service for a point-of-sale terminal adapter (POSTA) or other D-packet 
device. D-packet service is a 16 kbps data transmission service that uses the 
D-channel of an ISDN line.

To deliver D-packet service, a network connection (U-NT) is programmed 
to work with a terminal connection (U-LT). The loops must be on the same 
physical card. For example, if the network connection is a loop found on 
the BRI Card in Slot 1, the terminal connection must be a loop found on the 
same card.
S reference point
The S reference point connection provides a point-to-point digital 
connection between Norstar and ISDN terminal equipment (TE) that uses 
an S interface.
S loops support up to seven ISDN DNs, which identify TE to the ICS.

T reference points
The T reference point connections provide a point-to-point digital 
connection between the ISDN network and Norstar.
A T loop provides lines that can be shared by all Norstar telephones, 
peripherals and applications, and ISDN TE.
A T loop can be used in combination with an S loop to provide D-packet 
service for a point-of-sale terminal adapter (POSTA) or other D-packet 
device. D-packet service is a 16 kbps data transmission service that uses the 
D-channel of an ISDN line.
To deliver D-packet service, a network connection (T loop) is programmed 
to work with a terminal connection (S loop). The loops must be on the same 
physical card. For example, if the network connection is a loop found on 
the BRI Card in Slot 1, the terminal connection must be a loop found on the 
same card
Clock Source for ISDN Cards
Systems with ISDN interfaces need to synchronize clocking with the ISDN 
network and any connected ISDN terminal equipment. Clocking 
synchronization is supported by a Services Cartridge. 
The Compact ICS derives timing from the network using 
U-NT and T reference points (loops). Terminal equipment on U-LT and S 
reference points (loops) derive timing from the ICS.

Compact ICS 6.1 Installer GuideP0603539  02
Systems synchronize clocking to the first available, functional, network 
connection. If there are excessive errors on the reference network 
connection, or the loop fails, the next available, functional, network 
connection is used for clock synchronization. 
When you configure the network connections to the Compact ICS, you 
should take into account the system preferences for selecting loops for 
synchronization:
lower numbered loops have preference over higher numbered loops
the loop preference order is: 201, 202, 203, 204, 231, 232, 233, 234
the system skips U-LT, S, and analog loops when selecting a network 
connection for synchronization
Systems with only U-LT and S loops act as timing masters for the attached 
terminal equipment (TE), and are not synchronized to the network. ISDN 
TE without access to a network connection (BRI lines) has limited or no 
functionality.
Other ISDN BRI equipment
NT1
The NT1 (network termination type 1) connects an S interface (four-wire) 
to a U interface (two-wire). In most cases, it connects loops from a BRI-ST 
card to the network connection, which uses the U interface. It can also 
connect S interface terminal equipment (TE) to the U loop from a BRI-U2 
or BRI-U4 card.
An NT1 is not required to connect from the network to BRI-U cards or to 
connect U interface TE to an ICS equipped with BRI-U cards.
The NT1 converts and reformats data so it can be transmitted to and from 
the S or T connection. In addition, it manages the maintenance messages 
travelling between the network and the NT1, and between the NT1 and the 
ICS.
The NT1 from Nortel Networks is packaged two ways:
a stand-alone package which contains one NT1 card (NTBX80XX) 
and a power supply (NTBX81XX)
a compact package which contains up to 12 NT1 cards (NTBX83XX) 
and a power supply (NTBX86AA)

ISDN standards compatibility
Norstar ISDN equipment supports National ISDN standards for basic call 
and calling line identification services.
Norstar BRI is compliant with National-1.
Planning your ISDN network
Consult ISDN hardware on page 32 and ISDN programming on page 39 to 
determine a configuration of ISDN trunks and terminal equipment (TE) for 
the Compact ICS, then order the appropriate ISDN capability package from 
your ISDN service provider.
For ISDN BRI service your service provider supplies service profile 
identifiers (SPIDs), network directory numbers (Network DNs), terminal 
endpoint identifiers (TEIs), and other information that is required to 
program your Compact ICS, TE and other ISDN equipment.
Compact ICS does not support any package with EKTS (Electronic Key 
Telephone System), CACH (Call Appearance Call Handling), or Calling 
Name Display. EKTS is a package of features provided by the service 
provider and may include features such as Call Forwarding, Link, 
Three-Way Calling, and Calling Party Identification.
Ordering ISDN BRI
Ordering service in Canada
In Canada, order Microlink™ service, the trade name for standard BRI 
service. You can order either regular Microlink™ service, which includes 
the CLID (Calling Line Identification) feature, or Centrex  Microlink™, 
which includes access to additional ISDN network features (including Call 
Forwarding).
When ordering Microlink™ service, it must be ordered with EKTS 
(Electronic Key Telephone System) turned off. If you will be using a point-
of-sale terminal adapter (POSTA), ask for D-packet service to be enabled.

Ordering ISDN service in the U.S.
In the U.S., regardless of the CO (Central Office) type, order National 
ISDN BRI-NI-1 with EKTS (Electronic Key Telephone System) turned 
off. Use the following packages as a guideline for ordering your National 
ISDN BRI-NI-1. However we recommend using packages M or P with the 
Compact ICS. Contact your service provider for more information about 
the capability packages it offers. Bellcore/National ISDN Users Forum 
(NIUF ISDN packages supported by Compac tICS (for ordering in U.S.)
If you want to transmit both voice and data, and support D-channel packet 
service, order package P. However, Compact ICS does not support the 
flexible calling for voice and additional call offering features that are 
included in package P.
Multi-Line Hunt may be ordered with your package. When a telephone 
number (the Network DN) in the group of numbers assigned by your 
service providers is busy, the Multi-Line Hunt feature connects the call to 
another telephone number in the group. Norstar supports the feature only 
on point-to-point, network connections (T loop or U-NT loop). Check with 
your service provider for more information about Multi-Line Hunt.

Any of the ISDN packages will allow you to use sub-addressing, but your 
ISDN TE must be equipped to use sub-addressing for the feature to work.
ISDN programming
Most of the configuration programming for BRI lines and ISDN terminals 
and devices is done under 
Hardware. This section provides a programming 
overview for BRI lines, ISDN terminals and devices, and 
D-packet service.
Programming ISDN BRI resources
Some steps will not be necessary, depending on the service you are 
providing.
More detailed information is included under the individual headings and 
settings in the 
Programming and Maintenance sections.
For complete card and cartridge installation instructions and safety 
precautions, see Installation on page 69.
1. Collect the information supplied by your service provider to support 
your ISDN package. This includes network service profile identifiers 
(SPIDs) and Network DNs. If you are supporting a point-of-sale 
terminal adapter, you also need one or more terminal endpoint 
identifiers (TEIs).
2. Make sure a Combination Fiber 6-port Services Cartridge, or a 
Services Cartridge is installed in the ICS.
3. Install the BRI card in the ICS, Trunk Module (see Installing the 
cartridges on page 75 for information about BRI card placement), or 
determine which type of card you will preprogram the ICS to use in 
each slot.

4. Disable each card under Maintenance. 
5. Select a card type (BRI-ST, BRI-U2, BRI-U4) in 
Hardware.
6. Select the type for each loop in 
Hardware: 
For a BRI card, select T or S if the card type is BRI-ST. Select LT 
or NT if the card type is BRI-U2 or BRI-U4.
If the card uses an S, T or NT loop, enter the following 
configuration information, as supplied by your service provider: 
—the SPID assigned to the loop
—the number of B-channels associated with each SPID
—the Network DNs used with the network SPID
—the call type of the Network DN. 
Repeat the programming for the second network SPID, if any.
If the S, T or NT loop is used for D-packet service: 
—turn on the service
—assign the appropriate S loop mapping (for BRI-ST cards) or 
LT-loop mapping (for BRI-U2 or U4 cards)
—assign the TEIs (provided by the telco to support a 
point-of-sale terminal adapter or other D-packet service 
device) to the loop. 
If the loop type is S, select the sampling used on the loop.
If the loop type is S or LT, assign ISDN DNs to the loop and 
designate one of the assigned ISDN DNs to be the DN for the loop 
(Loop DN).
Note:You can have a maximum of 30 ISDN DNs on your system. The 
default ISDN DN range is 273–304. To change ISDN DN type, see 
Change DNs on page 211
7. Re-enable the card in 
Maintenance. If required, the card goes through 
a firmware download process, which takes five to six minutes. During 
a firmware download, the bottom LED on the BRI Card flashes.
8. Provision the loops and lines, as appropriate, in 
Maintenance 
programming. Refer to Provisioning on page 322
9. If you are configuring auto-answer BRI trunks to map to target lines, 
program the received number for the target line (a setting found under
