Trunk modeInstaller password required
Trunk mode allows you to specify either disconnect 
supervision or unsupervised. Disconnect supervision, also 
referred to as loop supervision, releases an external line when 
an open switch interval (OSI) is detected during a call on that 
line. This prevents the line from remaining unavailable for 
other Norstar users.
Press CHANGE
 to select the setting: Unspr or Super.
Unspr (the default) turns disconnect supervision off for the 
line.
Super assigns supervised mode, if supported by the line. 
otherwise, the line functions as unsupervised.
Ans mode
Installer password required
The Answer mode setting appears on the display during 
programming for loop start and BRI lines with a Trunk mode 
setting of Super, for groundstart (T1) lines, and for E&M lines. 
Press CHANGE
 to select the setting: Manual or Auto.
Tips - The duration of an open switch interval (OSI) before 
Norstar disconnects a call is programmed by the Discon timer 
setting under 
Hardware. 
Tips - Disconnect supervision is required for loop start 
trunks to operate in auto-answer mode or with DISA. It is also 
required to conference with two external callers. The line must 
be equipped with disconnect supervision from the central 
office for the Super option to work.

Ans with DISAInstaller password required
When activated, the Answer with DISA setting specifies that a 
trunk is answered with stutter dial tone. This feature is only 
active if Ans Mode is set to Auto.
Press CHANGE
 to select the setting: Y (Yes) or N (No). 
To program DISA on PRI trunk, see Programming Direct 
Inward System Access (DISA) on PRI trunks on page 64.
Tips - If loop start lines are set to Auto, you will require an 
E&M card for the DTMF receivers to function properly.
Remember that disconnect supervision is required if loop start 
trunks need to operate in auto-answer mode. 
You should change the Answer with DISA setting to N for 
E&M trunks in a private network operating in auto-answer 
mode. The default, Y (Yes), causes the system to expect a Class 
of Service password after it automatically answers a trunk.
Tips - For loop start and E&M lines this setting only 
appears if Answer mode is Auto. 
Set Ans with DISA to No for E&M lines on an enhanced 
switched network (ESN) to operate properly in auto-answer 
mode.
Tips - When an incoming call comes in on an auto-answer 
loop guarded or Earth calling line that is not configured to 
answer with DISA, the caller hears system dial tone. They can 
then enter a DIA line public received number to dial direct to 
an extension, a line pool access code to break out, or a remote 
feature code from a DTMF telephone if a suitable remote 
access package has been assigned.

Link at CO (loop trunks only)Installer password required
Some exchanges respond to a Link signal (²àÚ) by 
providing an alternative line for making outgoing calls. 
When Link at CO is set to Y (Yes), the system applies the 
restrictions on outgoing calls to the digits dialed after the 
Link signal, and the call on the alternative line will be 
subject to all restrictions. 
Setting Link at CO to N (No) prevents a Link signal from 
resetting the Norstar restrictions in cases where the host 
exchange does not provide an alternative line.
Press CHANGE
 to select the setting: Y (Yes) or N (No).
For more information about host signalling options, refer to 
Modular ICS 6.0 System Coordinator Guide.
Aux. ringer
Installer password required
This setting allows you to turn the auxiliary ringer on or off. 
An auxiliary ringer can be programmed on a line or a set. 
When programmed on a set, the auxiliary ringer will ring 
every time a call is received. When programmed on a line, the 
auxiliary ringer will not ring when a transferred call is 
received. 
Press CHANGE
 to select the setting: Y (Yes) or N (No).
Tips - The auxiliary ringer is an optional device that 
should be connected by the installer.
If you have an auxiliary ringer programmed to ring for calls 
on an external line, and you transfer a call on that line without 
announcing the transfer, the auxiliary ringer will ring for the 
call transfer.

Full AutoHoldInstaller password required
Full AutoHold on idle line is a variation of the Automatic Hold 
feature. If you select an idle line, but do not dial any digits, that 
line is automatically placed on hold if you select another line. 
Press CHANGE
 to select the setting: N (No) or Y (Yes).
The line you first selected is held until you press the line 
button. The line is not available for use by anyone else . 
LossPkg
Installer password required
Loss Package allows you to select the appropriate  loss/gain 
and impedance settings for each line. The setting is based on 
the distance between the ICS and the terminating switch, and 
the terminating switch type. When measuring the distance 
from ICS to CO and from ICS to PBX, use 600 ohms as the 
termination resistance setting.
A loss of 4 dB corresponds to a cable length of approximately
2700 m (9000 ft.).
Press CHANGE
 to select one of the following settings.
Tips - An auxiliary ringer can also be programmed in 
Services to ring for a line placed into a scheduled Ringing 
service. See the Modular ICS 6.0 System Coordinator Guide 
for more information.
Tips - The Full AutoHold setting appears only during loop 
start trunk programming. Full AutoHold is always in place for 
E&M trunks; it has no meaning for incoming-only DID trunks.
Only change the default setting if Full AutoHold is required 
for a specific application.

GainInstaller password required
Select the appropriate gain level for the line. 
Press CHANGE
 to select either: Normal or High. 
The default value Normal induces zero loss. Use it when the 
E&M trunks are connected to facilities that present 0 dBm at 
the interface, for both the transmit and receive paths.
Normal gain level (0dBm)
The value High induces 7 dB of loss in the receive path and 
16 dB of loss in the transmit path. Use it when the E&M trunks 
are connected to facilities that present +7 dBm in the receive 
path, and -16 dBm in the transmit path, at the interface.
High gain levels
Tip - Control over the gain on transmission levels can only 
be set for lines on E&M Trunk Cartridges.

Programming distinctive ring patternsInstaller password required
When lines are configured on your system, they can be 
assigned one of four distinctive ring patterns (DRP). The 
default for all telephones is 1; the default for lines is None, 
which is the lowest priority.
Call ringing: When multiple calls are presented to the 
telephone, the call with the highest priority DRP setting will be 
the call that rings at the telephone. 
Call answering: When multiple calls are presented to a 
telephone, and the user picks up the handset, the call with the 
highest priority DRP setting is the call that is presented.
Note:  External calls always have a higher priority than 
internal calls.
Note:  If the ring type is changed on a telephone after the DRPs 
are set on the line, the line DRPs are overwritten by the 
telephone settings. If the line DRPs are set after 
telephone programming, then the telephone ring 
programming is overridden by the DRP. Refer to the 
Modular ICS System Administrator Guide for details 
about setting ring types on a telephone.
If Hunt group DRP has a higher priority than the line 
DRP, the system will use the Hunt Group DRP within 
the Hunt Group. (Refer to Assigning a distinctive ring 
pattern to a Hunt Group on page 392.)

Restrn filters
Restriction filters are groups of dialing restrictions and dialing 
overrides for external numbers or feature codes. By packing a 
set of restrictions and overrides in one group, you can assign 
them to a line in one step, as a single package.
You can make changes to restriction filters under both 
Terminals&Sets, and Lines. Any changes will take affect 
for any telephone, line, or line on a telephone, regardless of 
where the programming was changed.
See the description and procedures in Restrictions on page 
349.
Line restrns
Specify the filter to be applied to this line to restrict the 
numbers that can be dialed on it. You can assign a different 
restriction filter for normal service and for each of the six 
schedules. See the section on Services for more information 
about the schedules.
Use ≠, CHANGE
 and the dialpad to enter the number 
of the restriction filter to be assigned as the line restriction for 
each schedule. 
The default restrictions are shown in the table below:
Default filters for lines 
Schedule Restriction filter
