How to use this document
This guide provides core installation and programming 
information for MICS 6.0 and MICS-XC 6.0 systems. If you 
are installing a MICS-XC system, also refer to the Modular 
ICS Companion Installer Guide for Companion installation 
and programming. 
The MICS system can be a mini (no expansion cartridge 
installed), a midi (installed with a two-port expansion 
cartridge), a maxi (installed with a six-port expansion 
cartridge), or a mega (Combination Fiber six-port Services 
Cartridges and Services cartridges) system. For more on 
the configurations, see Connecting expansion modules on 
page 224.
This version of the software does not support Companion.
The MICS-XC system has all the functionality of MICS, 
plus it supports the Companion wireless functionality. 
Both systems support ISDN PRI and BRI, and T1 
functionality. All MICS 6.0 functionality is described in this 
book. For system coordinators, the MICS 6.0 System 
Coordinator Guide explains how to perform common 
telephone programming.
Companion wireless programming and installation 
instructions are documented in the Modular ICS Companion 
Installer Guide and the Modular ICS Companion System 
Coordinator Guide.
Information that is specific to MICS-XC systems or MICS 
systems is clearly marked within this guide.
Note:Throughout this guide, reference to KSU refers to 
the Integrated Communication System (ICS).

What’s new with Norstar
The Norstar 0X32 MICS 6.0 includes several new features and 
a few functionality changes.
New features for version 6.0
Distinctive ring for lines and hunt groups
You can now assign distinctive ring patterns (DRP) to both 
lines and hunt groups. This is similar to the feature that 
allows you to assign different rings to your telephone so 
you can distinguish which phone is ringing. All three of 
these features work in concert with each other. Which ring 
will be used depends on the priority that is assigned to 
each, and the order in which the assignment occurred. 
Refer to Programming distinctive ring patterns on page 
348 and Assigning a distinctive ring pattern to a Hunt 
Group on page 392. 
System wide call appearance feature codes (SWCA)
Sixteen new feature codes allow you to assign indicator 
memory buttons with SWCA codes. These buttons provide 
call appearance for both incoming and outgoing calls to 
any group of telephones with the same assigned buttons. 
This allows a call to be parked on a SWCA button, and 
then the call can be retrieved by any other member of the 
group.
To upgrade from any previous version of 
MICS software to MICS 6.0, refer to 
Upgrading your Norstar system on page 189 
for detailed instructions. 
						

							34 / What’s new with Norstar
Modular ICS 6.0 Installer GuideP0992638 03
Calls are assigned to the SWCA buttons, either 
automatically or manually, at the telephone that receives or 
makes the call. This frees up the line for other calls while 
maintaining an appearance of the call in the group. Refer 
to Setting SWCA controls on page 403.
CLID display enhancements:
—alpha tagging using system speed dial name and CLID 
match
—system speed dial codes increased to 255
—Caller ID indicated for telephone rather than for 
individual lines
Alpha tagging is an enhancement to the CLID 
functionality of the system. This feature matches incoming 
call numbers with system speed dial entries. If enough 
digits match (CLID match), and the telephone is set to 
receive caller names (Caller ID set), then whatever name is 
entered into the system speed dial for that number will 
display when the call comes in. Refer to Sys speed dial on 
page 381. 
Note:Alpha tagging  activates when the CO line service 
supplies only a number for the incoming call. 
Otherwise, the system uses the name supplied by the 
CO line service.
To support this feature, the system speed dial codes have 
been increased to 200 entries, with three-digit codes from 
001 to 255. Refer to the MIC ICS 6.0 System Coordinator 
Guide for a detailed description of System Speed dial 
programming.

off-core DTI for profiles 1 and 4, allowing additional PRI 
lines (new line pool)
Profile 1 and 4 customers can now add an additional DTI 
card to their midi (module 3 or 4) and maxi systems 
(module 7 or 8) to provide extra T1 or PRI lines to their 
system. Since the card uses all available lines on the 
module, no other cards can be installed into the module 
with this card.
Further enhancements have been made to MCDN 
functionality, which is supported in profiles 1, 2, and 3.
—TAT Refer to Trunk Anti-tromboning on page 140.
—ICCL Refer to ISDN Call Connection Limitation on 
page 136.
—Centralized voice mail and auto attendant on Norstar 
Voice Mail platform
—Centralized voice mail provided by Meridian Mail 
provides attendant features: camp-on (Camp-on on 
page 142) and break-in (Break-in on page 143)).
Functionality changes for version 6.0
Profile 2: This profile has been adjusted to accommodate 
systems which use ETSI PRI lines with an a-law 
companding protocol. 
—The off-core DTI module is not supported on this 
profile.
—T1 functionality has been removed from this profile.
—The PRI SL-1 MCDN protocol, and all the networking 
features this protocol supports, is supported on this 
system. Refer to MCDN services (profiles 1, 2, 4) on 
page 445. 
						

							36 / What’s new with Norstar
Modular ICS 6.0 Installer GuideP0992638 03
—As well, the EURO PRI protocol is supported for this 
profile.
—In addition, the central office ETSI PRI features: 
Network Call Redirection and Malicious Caller ID 
(MCID) can be used if they are allowed by your service 
provider. Refer to ETSI: Network diversion and MCID 
(profile 2 only) on page 442.
Line renumbering: Due to the addition of ETSI to Profile 
2, the line numbering for the entire system has been 
realigned to accommodate the extra lines provided by 
ETSI lines. When you perform an upgrade, existing line 
assignments will be automatically updated. Refer to Trunk 
module line numbering on page 205 for a comparison table 
of line numbering based on software versions. Refer to 
TrunkMod on page 467 for detailed line numbering based 
on the type of trunk module that is installed. This change 
includes the target line numbers.
Due to the expansion of the system speed dial feature 
codes up to 255, the user speed dial list has been changed 
to codes 256 to 279 (24 codes, no change from existing 
systems). Refer to User prefernces on page 321.

Welcome to ISDN
This chapter provides you with some background information 
about ISDN, including information about:
analog vs. ISDN
type of ISDN service
ISDN layers
ISDN bearer capability
services and features for ISDN PRI and BRI
ISDN hardware
ISDN standards compatibility
Integrated Services Digital Network (ISDN) technology 
provides a fast, accurate, and reliable means of sending and 
receiving voice, data, images, text, and other information 
through the telecom network. 
ISDN uses existing analog telephone wires. The signal on the 
wire gets divided into separate digital channels, which 
dramatically increases the bandwidth.
ISDN uses a single transport to carry multiple information 
types. What once required separate networks for voice, data, 
images, or video conferencing is now combined on to one 
common high-speed transport.
Note:  Nortel endeavors to test all variations of ISDN BRI and 
PRI on Norstar. However, due to the number of 
variations, this is not always possible. Check with your 
service provider about compatibility.

Modular ICS 6.0 Installer GuideP0992638 03
Comparing ISDN to Analog
ISDN offers significantly higher bandwidth and speed than 
analog transmission because of its end-to-end digital 
connectivity on all transmission circuits. Being digital allows 
ISDN lines to provide better quality signaling than analog 
POTS (plain ordinary telephone) lines. Also ISDN out-of-
band data channel signaling offers faster call setup and tear 
down.
While an analog line carries only a single transmission at a 
time, an ISDN line can carry one or more voice, data, fax and 
video transmissions simultaneously. 
An analog modem operating at 14.4 K takes about 4.5 minutes 
to transfer a 1MB data file and a 28.8K modem takes about 
half that time. Using one channel of an ISDN line, the transfer 
time is reduced to only one minute. If two ISDN channels are 
used, transfer time is just 30 seconds.
When transmitting data, the connect time for an average ISDN 
call is about three seconds per call, compared to about 21 
seconds for the average analog modem call.
Type of ISDN service
Two types of ISDN services (lines) are available: Basic Rate 
Interface (BRI) and Primary Rate Interface (PRI). Each line is 
made up of separate channels known as B and D channels 
which transmit information simultaneously.
BRI is known as 2B+D because it consists of 
2 B-channels and one D-channel.
PRI is known as 23B+D because it consists of 
23 B-channels and one D-channel.

B channels
B channels are the bearer channel. They are used to carry voice 
or data information and have speeds of 64 kbps. Since each 
ISDN line (BRI or PRI) has more than one B-channel, more 
than one transmission can occur at the same time, using a 
single ISDN line. 
D channels
The standard signaling protocol is transmitted over a dedicated 
data channel called the D-channel. The D-channel carries call 
setup and feature activation information to the destination. 
This channel has speeds of 16 kbps (BRI) and 64 kbps (PRI). 
Data information consists of control and signal information 
and packet-switched data such as credit card verification.
ISDN layers
ISDN layers refer to the standards established to guide the 
manufacturers of ISDN equipment. The layers include both 
physical connections, such as wiring, and logical connections, 
which are programmed in computer software. 
When equipment is designed to the ISDN standard for one of 
the layers, it works with equipment for the layers above and 
below it. 
There are three layers at work in ISDN for Norstar. To support 
ISDN service, all three layers must be working properly. 
Tip - Norstar PRI supports the D-channel on the 24th 
channel only. Norstar does not include support for a 
backup D-channel on the span.

Modular ICS 6.0 Installer GuideP0992638 03
Layer 1: A physical connection that supports fundamental 
signaling passed between the ISDN network (your service 
provider) and the Norstar ICS. When a DTI card configured as 
BRI or PRI is used for a network connection, the LED for the 
loop on the card is lit when the layer 1 is functioning.
Layer 2: A logical connection between the ISDN network 
(your service provider) and the Norstar ICS. Norstar has two 
of these connections for each BRI line, one for each of the 
logical lines. Without Layer 2, call processing is not possible, 
and there is no dial tone. 
Layer 3: Also a logical connection between the ISDN network 
(your service provider) and the Norstar ICS. For BRI lines, 
layer 3 is where call processing and service profile identifier 
(SPID) information is exchanged. This controls which central 
office services are available to the connection. For example, a 
network connection can be programmed to carry data calls.
The system of layers is important when you are installing, 
maintaining, and troubleshooting an ISDN system. See 
Problems with BRI service on page 570 for more information 
about working with the layers.
ISDN bearer capability
Bearer capability describes the transmission standard used by 
the BRI or PRI line that allows it to work within a larger ISDN 
hardware and software network. 
The bearer capability for BRI and PRI is voice/speech at 
3.1 kHz audio, and data at unrestricted 64 kbps, restricted 
64 kbps, 56 kbps.
