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.

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.

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,...

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...

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...

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...

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

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...

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.

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...
