Emergency telephone
You can connect an emergency telephone to an ICS or Trunk 
Module (TM) with a Loop Start Trunk Cartridge to provide 
emergency service when there is no power to the ICS. The ICS 
has emergency telephone connections for lines 002 and 026 
(profile 1, 3 and 4) or 002 to 030 (profile 2). Each Trunk 
Module has one emergency telephone connection.
1. Wire a modular jack or equivalent to each set of 
emergency telephone pins on the 50-pin distribution block 
for the ICS or Trunk Module external lines. 
Refer to Wiring charts on page 252 for the pin numbers.
2. Connect a single-line telephone (500/2500) to the modular 
jack.
3. Prepare to test the emergency telephone by removing the 
Trunk Cartridge from the slot (slot 3 or 4 on the ICS, and 
slot 1 on the TM).
4. Connect the power, then connect the central office lines to 
the ICS.
5. Pick up the emergency telephone receiver and listen for 
dial tone.

do not support emergency telephones:

6. Disconnect the central office lines, then remove power 
from the system.
7. Replace the Trunk Cartridge in the left slot.
8. Continue with procedures for powering up the system.
Tips - The emergency telephone connections on the Trunk 
Module will not work if there is an E&M/DISA, a BRI-ST or 
BRI-U card, or a DID Trunk Cartridge in the first slot of the 
Trunk Module. The emergency telephone connections on the 
ICS will not work if DTIs or PRIs are used.
Tips - Norstar telephones and Business Series Terminals 
cannot be used as off-premise telephones (OPX). For OPX 
applications, use the Norstar Analog Terminal Adapter 
(ATA2) and a single-line telephone. Refer to the ATA 
Installation Card for details. 
						

							Moving telephones / 283
P0603534  02Modular ICS 6.1 Installer Guide
Moving telephones
You can move a system telephone to a new location within the 
Norstar system without losing the programmed settings. 
When Set relocation is enabled in system programming, 
the internal numbers, autodial settings, and personal speed dial 
codes remain with the telephone when it is unplugged. 
To move a telephone, simply unplug it and plug it in again at 
another location. It may take up to 45 seconds for the ICS to 
recognize the telephone. Automatic telephone relocation is 
disabled by default.
Tips - Relocate the disconnected system telephone before 
connecting a new telephone into the vacated jack. This allows 
the moved telephone to retain the programmed settings. 
If a new telephone is plugged into the vacated jack before the 
old telephone is reconnected at a new location, Norstar will 
give the current telephone information to the new telephone. 
The old telephone will no longer be recognized by the system. 
When reprogramming the internal number of a telephone, wait 
one minute after Automatic Telephone Relocation.
When you relocate a telephone, the telephone must remain 
installed and connected in the new location for at least three 
minutes for the programming relocation to be complete. 
Moving the telephone again before the three-minute period 
may result in losing the programming on the telephone. 
						

							284 / Installing ISDN BRI terminal equipment
Modular ICS 6.1 Installer GuideP0603534  02
Installing ISDN BRI terminal 
equipment
For each S or T or U-LT reference point, an eight-position 
miniature unkeyed plug from the terminal equipment (TE) is 
plugged into a jack connected to Norstar wiring. The pin 
connections for the jack and plug are shown in the following 
charts.
S or T wiring for terminal equipment
S or T extension wiring configurations
The last connection on any ISDN S or T extension wiring must 
have terminating resistors to ensure correct timing of the 
signaling circuits. Failure to install terminating resistors will 
degrade performance. Terminating resistors should not be 
connected on a TE which is not the last connection on the loop.
Terminating resistors are provided on terminal equipment. See 
the instructions that come with your TE for information about 
how to enable or disable the termination, as required.

The maximum length of spur and ISDN connection cord 
(the extension from the main line or bus) is 10 m (30 ft). 
Refer to S reference point on page 57 and T reference points 
on page 58 in the Welcome to ISDN chapter for information 
about wiring arrangements for ISDN terminal equipment (TE) 
on an S or T loop.
Additional power
A Norstar S or T-loop does not provide power on Power 
Source 1 (PS1), Power Source (PS2), or Power Source or 
Sink 3 (PS3). If you are installing ISDN terminal equipment at 
the S-reference point, and the equipment requires additional 
power on PS1, PS2, or PS3, then you can install a suitably-
approved power supply unit. See ANSI T1.605 or the 
documentation that comes with your TE for details.
The Modular ICS does not require power on PS3.
Wiring arrangements using side circuits, also called phantom 
circuits, may affect loop performance when they are used to 
provide power to the TE (PS1). You must account for any 
effects. For example, you may need to reduce the number of 
TEs on a passive bus.

No power supply is provided for the U-LT wiring. If 
equipment attached to the U-LT loop requires optional power, 
install an approved power supply unit. See ANSI T1.601-1992 
Annex H or the documentation that comes with your TE for 
more information.

Installing optional equipment
This section describes the installation procedures for optional, 
customer-suppled equipment.
Auxiliary ringer (customer supplied)
The Norstar ICS provides a control contact to operate an 
auxiliary ringer. 
1. Follow the installation instructions provided by the 
manufacturer.
2. Connect the auxiliary ring generator to the 50-pin 
distribution block as shown in the wiring charts.
The pins in this chart provide a control contact. They do 
not provide ring current or DC voltage. The ringer must 
not draw more than 50 mA from a 40 V DC source.
Auxiliary ringer programming
The auxiliary ringer can be activated by setting auxiliary ring 
for specific external lines, and auxiliary ring for specific 
telephones. Refer to the Modular ICS 6.1 System Coordinator 
Guide for programming details.

External music source (customer supplied)
The music source can be any approved low-power device such 
as a radio with a high-impedance earphone jack. The 
recommended ICS input level is 0.25 V rms across an input 
impedance of 3300 Ω.
1. Connect the music source output to the 50-pin distribution 
block, as shown in the wiring charts.
2. Adjust the volume of the music source to a comfortable 
level by activating Background Music (
≤°fl) and 
adjusting the volume at the music source. 
External music source programming
Music for callers on Hold and for Background Music must be 
enabled through programming. Refer to Backgrnd music on 
page 419 for more details. 
Confirm that the following settings are implemented:
Tips - Background Music volume can also be adjusted at 
each telephone.

External paging system (customer supplied)
You can connect an external paging system to provide paging 
over external loudspeakers. The paging output from the 
Norstar ICS is 100 mV rms across an input impedance of 
600 Ω.
1. Follow the installation instructions provided by the 
manufacturer.
2. Connect the paging system audio input to the 50-pin 
distribution block as shown in the wiring charts.
3. Connect the paging system relay to the 50-pin distribution 
block as shown in the wiring charts.
External paging contacts
Tips - Norstar external paging does not support talk-back 
paging equipment unless an external line port is used.
The Norstar system provides paging over the Norstar 
telephone speakers, even when no external paging equipment 
is connected.

							290 / Powering up the system
Modular ICS 6.1 Installer GuideP0603534  02
Powering up the system
1. Double-check all wiring before turning the system power 
on. Ensure all outlets where you will plug in the modules 
are non-switchable, third-wire ground AC outlets.
2. Route the module power cords through the lower shelf of 
the cable trough and out through the bottom of the ICS 
cable trough.
3. Route the ICS power cord through the bottom of the ICS 
cable trough.
4. Connect each power cord to an electrical outlet.
If you are using a power bar, plug the power cords into the 
power bar, and then connect the power bar to the 
AC outlet.
Do not connect central office line cables to the 
modules until after the system power is on.
Companion: Install Base Stations before powering 
up the MICS-XC system.
Do not fasten power supply cords. 
Do not fasten the ICS power supply cord or module 
power supply cords to any building surface, including 
the backboard.
