Lines) to be the same as the Network DN supplied by your service 
provider.
10. Assign the ISDN lines and target lines to the appropriate ISDN DNs 
(the set of DNs reserved for use by ISDN devices) under 
Line access, a subheading of Terminals&Sets. ISDN lines can also 
be assigned to the DNs used by Norstar telephones or any other 
devices connected to the Compact ICS.
11. 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 42. 
If you are setting up a D-packet service, program the point-of-sale 
terminal adapter or other D-packet service device with the appropriate 
TEI (provided by your service provider), terminal SPID, and DN by 
following the instructions that come with the device.
Programming ISDN BRI lines
When the configuration programming under Hardware is complete, your 
BRI lines are ready to be programmed in the same way as analog lines. You 
can, for example, place them in pools and assign them to Norstar or 
Business Series Terminals (BST) telephones and ISDN terminal 
equipment. However, there are some differences in the way BRI lines work 
that will influence how you configure them to handle incoming and 
outgoing calls.
For BRI lines, in most cases, your service provider supplies two SPIDs, one 
for each B channel. Each SPID and one or more Network DNs are 
associated with a single line. Calls to a Network DN come in on a specific 
line, and pressing a line button selects the same line every time.
If your service provider supplies you with a single SPID for both 
B channels, incoming and outgoing calls are handled according to the loop. 
The two lines provided by the BRI loop are pooled for both incoming and 
outgoing calls. 
For example, if Loop 201is programmed with a single SPID, which 
supports lines 001 and 002, incoming calls made to a Network DN 
associated with the SPID appear on either line 001 or line 002. If you press 
the line button for line 001, either line 001 or line 002 is selected. For loops

which use a single SPID, assign both lines on a loop to a telephone to 
guarantee that all calls appear at the telephone.
Programming ISDN equipment
Terminal equipment for BRI cards
Unlike Norstar or BST telephones, ISDN devices and terminals connected 
to the ICS must be configured under the 
Hardware heading in system 
programming. You choose directory numbers for ISDN equipment from a 
pre-determined range of DNs (273-304). Any of the ISDN DNs can be 
assigned to any U-LT or S loop, but each can only be assigned to one loop 
and a single device.
Devices on an S or LT loop (BRI cards only)
Terminal equipment using a U-LT loop or S loop must be assigned an 
ISDN directory number (ISDN DN). This allows you to assign lines to the 
terminal equipment and allows the TE to communicate with other devices 
connected to the ICS. Each DN can be assigned only to one TE and to one 
loop. 
You assign ISDN DNs to S loops and LT loops under 
Assign DNs in 
Hardware programming. Each S or LT loop can be programmed with eight 
ISDN DNs, but you cannot exceed a total of 30 ISDN DNs for the Compact 
ICS.
Once you have assigned ISDN DNs to a loop, designate one of the DNs as 
a Loop DN. The Loop DN acts as a main ISDN DN and completes the 
configuration of the loop.
The ISDN terminal equipment (TE) on the loop is also programmed with 
its ISDN DN. See the instructions that come with the ISDN device for 
information about how to program it to recognize its assigned DN. Most 
devices will require both a terminal service profile identifier (terminal 
SPID) and a DN. Some will require two terminal SPIDs and two ISDN 
DNs. The SPID used with the device should not be confused with a SPID 
used for network connections using an T or NT loop.
To create a terminal SPID for a device, add at least two zeros to the end of 
the of the ISDN DN. Add more zeros to the beginning or end of the ISDN

DN until you have the length of SPID required by the TE. For example, if 
an ISDN telephone requires a six-digit SPID and has a DN of 73, its SPID 
is 007300. If the same TE requires a minimum of 10 digits, the SPID is 
0000007300. 
Most ISDN terminals require a five-digit SPID. An ISDN computer card 
usually requires a 10-digit SPID. Follow the directions that come with the 
ISDN device to program it with a SPID and ISDN DN.
The following table uses the example in the illustration to show the 
programming for the S loop.

ISDN router
By connecting an ISDN router to your Compact ICS, a group of computers 
can share Internet access. This arrangement is best for a workplace where 
each computer occasionally uses an Internet connection.
To support Internet access, you must order BRI lines from your service 
provider, and subscribe to Internet service from an Internet service 
provider (ISP). Your computers must have an Internet browser and any 
applications supplied by your ISP.
D-packet service (BRI cards only)
The D-packet service supplied by the Compac tICS supports a point-of-
sale terminal adapter (POSTA). Connecting a POSTA allows transaction 
terminals (devices where you swipe credit or debit cards) to transmit 
information using the D channel of the BRI line, while the B channels of 
the BRI line remain available for voice and data calls. A special adapter 
links transaction equipment (such as cash registers, credit card verification 
rigs, and point-of-sale terminals) to the X.25 network, a data 
communications network designed to transmit information in the form of 
small data packets.
To support the D-packet service, your ISDN network and financial 
institution must be equipped with a D-packet handler. To convert the 
protocol used by the transaction equipment to the X.25 protocol, your

ISDN network must also be equipped with an integrated X.25 PAD which 
works with the following versions of X.25: Datapac 32011, CCITT, 
T3POS, ITT and API. The ISDN service package you order must include 
D-packet service (for example, Package P in the U.S.; Microlink™ with 
D-channel in Canada). 
Your service provider supplies a Terminal Endpoint Identifier (TEI) and 
DN to support D-packet service. The TEI is a number between 00 and 63 
(in Canada, the default range is 21-63). Your service provider may also 
supply you with a DN to program your D-packet device. The DN for 
D-packet service becomes part of the dialing string used by the D-packet to 
call the packet handler.
POSTA for ISDN BRI
When you configure D-channel packet service, you are specifying the 
transmission path between an ISDN loop on the network side of the ICS 
and the ISDN loop on the set side (the loop used by the point-of-sale 
terminal adapter). The service is turned on and configured using the 
network loop programming found under 
Hardware (NT loop for BRI-U2 
and BRI-U4 Cards; S or T loop for BRI-ST Cards).
To set up D-packet service:
go to the programming settings for the network loop (S, T, or NT loop) 
under 
Hardware
select the S loop or LT loop used by the POSTA
enter the terminal endpoint identifiers (TEIs) supplied by your service 
provider
Point-of-sale terminal adapter
The point-of-sale terminal adapter is an analog device that connects to 
point-of-sale devices using an RS-232 interface and a U-LT loop. It 
handles the routing of packet information from the devices to the ICS and 
into the ISDN network. 
Your service provider (usually a financial institution) supplies you with 
information about the compatible controller, which handles the routing of 
packet information from the devices to the ICS and into the ISDN network.

Networking with Norstar
In addition to public network connections, Norstar Compact ICS can be 
integrated into an existing private network or to other Norstar systems to 
form a corporate telecommunications network.
The big picture
Norstar uses enhanced trunking to join other Norstar or customer 
equipment in a private network. Authorized users can also access central 
office lines and Norstar features from outside their Norstar system.
Callers using the Norstar Compact ICS system can
call directly to a specific Norstar telephone
select an outgoing central office line to access the public network
use all of the Norstar features
Callers in the public network can
call into the Norstar Compact ICS system and select an outgoing 
central office line to access the public network
call into the Norstar Compact ICS system and use remote features
Norstar behind a PBX
Norstar Compact ICS can be used behind a PBX. In order to support this 
application, the trunk lines must be set up not to exceed 8 dB total loop loss 
from the serving central office to the connection point at the Norstar ICS.

Trunks and target lines
Trunks are external lines that provide the physical connection between a 
Norstar system and other systems in a private or public network. Norstar 
Compact ICS supports two different types of trunks:
Loop start trunks handle incoming and outgoing calls between Norstar 
and the public network. They are numbered 001-004 and 031-034.
BRI trunks handle incoming and outgoing calls between Norstar and 
an ISDN network. They are numbered from 001-008 and 031-038.
Target lines are virtual communication paths between trunks and 
telephones on the Norstar system. They are incoming lines only, and 
cannot be selected for outgoing calls. You can use target lines to simulate 
direct inward dialing (DID) service by routing calls to telephones 
according to the digits received from the central office on a BRI trunk.
Target lines are numbered 061 to 086. Telephones can  be configured to 
have an appearance of any type of trunk and line (including target  lines).
Loop start trunks
Loop start trunks provide incoming and outgoing access to the public 
network. Loop start trunks can be configured as manual-answer or 
auto-answer. The answer mode determines how the system handles 
incoming calls.
When a call comes in on a manual-answer loop start trunk, it alerts at all 
telephones with that line appearance. 
When a call comes in on an auto-answer loop start trunk that is configured 
to answer with direct inward system access (DISA), the caller hears a 
stuttered dial tone. They must enter a six-digit Class of Service (COS) 
password from a dual tone multifrequency (DTMF) telephone to access 
system dial tone. Once the caller has system dial tone, they can then enter 
a target line number, a line pool access code or a remote feature code. 
By default, auto answer loop start trunks are configured to answer with 
DISA, and are used to provide controlled access to Norstar system 
resources.

P0603539  02Compact ICS 6.1 Installer Guide
When a call comes in on an auto-answer loop start trunk that is not 
configured to answer with DISA, the caller hears system dial tone. They 
can then enter:
a target line number
a DISA DN, which is the number that will prompt for a COS password
a line pool access code
a remote feature code from a DTMF telephone
To place an outgoing call, a loop start line can be selected by pressing a line 
button on the telephone, by dialing a line pool access code, or by pressing 
a memory button that has been programmed with a line pool access code.
Tip - Loop start signaling is supported by Loop Start /
Disconnect Supervision (LS/DS) Analog Trunk Cartridges 
and Call Information (CI) Trunk Cartridges. Each LS/DS 
Analog Trunk Cartridge or CI Trunk Cartridge can provide 
four loop start trunks. To configure the loop start trunks as 
auto-answer, the trunks must have disconnect supervision 
enabled. The central office must provide far end disconnect 
supervision.
The default programming for trunks uses disconnect 
supervision. If the central office does not provide far end 
disconnect supervision, the Trunk Mode setting in Lines 
programming should be changed to unsupervised.
You may configure a loop start trunk as the prime line for a 
Norstar telephone. The prime line is the line the telephone 
u s es  a ut omat i call y i f no oth er  l in e is  chose n or no li ne p ool i s 
entered.
The capabilities available to a remote caller are determined 
by the remote restrictions and remote package assigned to a 
line, or by the set restrictions, line restrictions and remote 
package assigned to the COS password.
Callers can also access the system by using the Auto 
Attendant features. See the Compact ICS Coordinator Guide 
for more information.

BRI trunks
BRI trunks give you incoming and outgoing access to an ISDN network. 
Like loop start trunks, they can be configured as manual-answer or auto-
answer. See the Loop start trunks information that starts on page 48 for 
information on setting the answer mode.
BRI trunks provide a fast, accurate and reliable means of sending and 
receiving data, images, text and voice information. Using BRI lines allows 
for faster transmission speeds and the addition of a variety of powerful 
business applications, including remote LAN access, video conferencing, 
file transfer and Internet access.
For more information see Welcome to ISDN on page 27 .
Target lines
A target line is a specific communication path that is reached by means of 
digits received from an incoming BRI trunk. Target lines are used to 
answer incoming calls but cannot be used to make outgoing calls.
You can program auto-answer BRI trunks to map to target lines to provide 
for attendant bypass (calling directly to a department or individual) and line 
concentration (one trunk can map onto several target lines).
No target lines are assigned to sets by default.
Target lines are referred to by line numbers (061-086) in the same way as 
physical lines.
Privacy issue
You can set a target line to Private (default is 
Public), however, such features as Call Pickup 
can still answer these lines from other system 
telephones.
