DID supervisory signaling
This equipment returns supervisory signals to the public 
switched telephone network (PSTN) when the DID calls are:
answered by the called telephone
answered by the attendant
routed to a customer controlled recorded announcement
routed to a dial prompt
This equipment is designed to return supervisory signals on all 
DID calls forwarded through the system back to the PSTN 
within 20 seconds of call forwarding being initiated. 
Emergency transfer conditions
Every DID Trunk Cartridge has a Control Circuit Interface 
(CCI) which should be connected directly to the central office 
for monitoring purposes.
If the Norstar system loses power or the microcontroller on the 
DID Trunk Cartridge malfunctions, the CCI signals the central 
office that it can no longer handle DID calls. The central 
office, by prearrangement, then forwards the DID lines to 
other numbers. 
Connect the CCI com1 connection to a ground connection. 
Connect the CCI NC1 connection to the central office 
demarcation.
Tips - CCI signaling to report power loss or malfunction 
of the DID Trunk Cartridge is not supported by all carriers. 
For carriers or installations which do not use CCI signaling, 
the CCI and ET connections are treated as not connected.
Wire each  CCI independently to the central office. If the 
connections are wired in parallel, any CCI trouble disables all 
DID Trunk Cartridges. If the connections are wired in series, 
all DID Trunk Cartridges must fail before the central office 
recognizes the trouble condition.

							Emergency telephone / 265
P0992638 03Modular ICS 6. 0 Installer Guide
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. 
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 241 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.
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 / 267
P0992638 03Modular ICS 6. 0 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 jack. This allows the 
moved telephone to retain the programmed settings. 
If a new telephone is plugged into the 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.

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 on 
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 51 and T reference points 
on page 51 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.

U-LT wiring for terminal equipment
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.
