Working with ISDN
Planning your ISDN network
Consult ISDN hardware on page 54 and ISDN programming 
on page 66 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 about the supported protocols and 
services, refer to Call by Call service selection for PRI on page 
457.
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.
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 219.
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 223 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. 
Tips - For systems running 6.0 or greater software, a DTI 
card 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 supported on 
Profile 1 and 4.
Note: Legacy DTI cards cannot be used off-core. A new DTI 
card was released in 2002 that can be used in any position.

the DTI card for PRI on page 483, for information about 
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.
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 219.
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 has been installed in the ICS.
3. Install the BRI card in the ICS, Trunk Module. Refer to 
Installing the cartridges on page 223 for information about

BRI card placement. If you are not using a BRI card, 
determine which type of card you will preprogram the ICS 
to use in each slot.
4. Disable each card in Maintenance under Module 
Status. 
5. Under Hardware, select a card type: BRI-ST, BRI-U2, 
BRI-U4.
6. Under Hardware, select the type for each loop: 
• for a BRI card, select T or S if the card type is BRI-ST
• for a BRI-U2 or BRI-U4 card, select LT or NT
7. If the card uses a T or NT loop, enter the following 
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 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 to the loop. These are provided by the 
telco to support a point-of-sale terminal adapter or 
other D-packet service device.
If the loop type is S, select the sampling used on the loop. 
						

							70 / Working with ISDN
Modular ICS 6.1 Installer GuideP0603534  02
If the loop type is S or LT:
• assign ISDN DNs to the loop
• 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 667–696 for a 
system with three-digit DNs. To change ISDN DN 
type, see Change DNs on page 418.
8. Re-enable the card in Maintenance. Refer to Disabling a 
PRI Channel on page 551.
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.
9. Provision the loops and lines, as appropriate, in 
Maintenance. Refer to Provisioning BRI and PRI lines on 
page 549.
10. If you are configuring auto-answer BRI trunks to map to 
target lines, program the received number for the target 
line to be the same as the Network DN supplied by your 
service provider. This setting is found under Lines.
Assign the ISDN lines and target lines to the appropriate 
ISDN DNs, which are the set of DNs reserved for use by 
ISDN devices. This setting is found under 
Terminals&Sets/Line access. ISDN lines can also be 
assigned to the DNs used by the telephones or any other 
devices connected to the Modular ICS.
Program the ISDN terminals and devices with the 
appropriate ISDN DNs and terminal SPIDs by following 
the instructions that come with the devices. For more 
information, see Programming ISDN equipment on page 
73.
