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 either a point-to-
point or point-to-multipoint 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 either a 
Combination Fiber 6-port Services Cartridge or a Services 
Cartridge. 
The Modular 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.
Systems synchronize clocking to the first available, functional, 
network connection. If there are excessive errors on the 
network

reference network connection, or the loop fails, the next 
available, functional, network connection is used for clock 
synchronization. 
The clock synchronization process generates alarm codes and 
event messages. See the Alarm codes on page 506 and Event 
messages on page 514 for more information.
When you configure the network connections to the Modular 
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, 225, 226, 
227, 228
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.
If your system has both a BRI and a DTI card configured as 
PRI installed, it is recommended that you use PRI as the 
primary clock source, see DTI card configured as a PRI card 
on page 47.

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 modular 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 and PRI is 
compliant with National-2.
Modular ICS does not support EKTS (Electronic Key 
Telephone System) or CACH (Call Appearance Call 
Handling).

Working with ISDN
Planning your ISDN network
Consult ISDN hardware on page 48 and ISDN programming 
on page 58 to determine a configuration of ISDN trunks and 
terminal equipment (TE) for the Modular 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, as required, to program your Modular ICS, 
TE and other ISDN equipment.
Modular ICS does not support any package with EKTS 
(Electronic Key Telephone System) or CACH (Call 
Appearance Call Handling). 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 PRI
When you order ISDN PRI, order two-way DID because it 
simplifies provisioning and provides efficient use of the PRI 
bandwidth.
Ordering ISDN PRI service in Canada
In Canada, order Megalink™ service, the trade name for 
standard PRI service and set the Norstar equipment to the 
supported protocol that is identified by your service provider, 
either DMS-100 or NI-2.

Ordering ISDN PRI service in United States
In the United States order PRI service from your service 
provider. Set the Norstar equipment to the PRI protocol 
provided by your service provider.
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 
Modular ICS. Contact your service provider for more 
information about the capability packages it offers .

Bellcore/National ISDN Users Forum (NIUF) ISDN packages 
supported by Modular ICS (for ordering in U.S.)
If you want to transmit both voice and data, and support 
D-channel packet service, order package P. However, 
Modular 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.

Supported ISDN protocols
The switch used by your service provider must be running the 
appropriate protocol software and the correct version of that 
software to support ISDN PRI and ISDN BRI. Each protocol 
is different and supports different services. Contact your 
service provider to ensure that your ISDN connection has the 
protocol you require.
For more information on the supported protocols and services, 
refer to Call by Call service selection for PRI on page 433.
ISDN programming
Most of the configuration programming for PRI and BRI lines 
and ISDN terminals and devices is done under Hardware. This 
section gives you an overview of programming for PRI and 
BRI lines, ISDN terminals and devices, and D-packet service.
Programming ISDN PRI resources
Some steps will not be necessary, depending on the service 
you are providing.

safety precautions, see Installation on page 209.
1. Collect the information supplied by your service provider 
to support your ISDN package. 
2. Ensure that a Combination Fiber 6-port Services 
Cartridge, or a Services Cartridge has been installed in the 
ICS.
3. Install the DTI cards in the ICS. Refer to Installing the 
cartridges on page 213 for information about card 
placement. If you are not using DTI cards, 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 (PRI) in Hardware. See Provisioning the 
DTI card for PRI on page 456, for information on protocol 
and other settings you must configure.
6. 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 DTI card 
flashes.
Tips - A new DTI card being released with MICS 6.0 can 
be installed off-core on Module 3 or 4 on the Midi system, or 
module 7 or 8 on the Maxi system to expand the PRI capability 
of your system. This card is only support on Profile 1 and 4.
Tips - If you are using one or more of the lines on this card 
for MCDN private networking, this is where you specify that 
protocol (SL-1).
