users can receive calls.
If a voice terminal user attempts to place a call, intercept tone is received. A 
voice terminal can, however, activate certain features by dialing the assigned 
feature access codes.
Considerations
Origination Restriction is used whenever a voice terminal is to be used only for 
answering incoming calls.
Interactions
When the system authorizes a call, Controlled Restrictions are checked as well 
as those restrictions assigned by COR.
Administration
The Origination Restriction feature is administered by the System Manager to 
voice terminals by the Class of Restriction feature.
Hardware and Software Requirements
No a d ditional hardware or software is required.

Calls can be placed to other voice terminal users, to the attendant, and over tie 
trunks.
Considerations
Outward Restriction is used whenever it is desired that a voice terminal make 
only internal calls.
The attendant or an unrestricted voice terminal user can extend a call to an 
outside number for the outward-restricted voice terminal user.
Interactions
When the system authorizes a call, Controlled Restrictions are checked as well 
as those restrictions assigned by COR.
Administration
The Outward Restriction feature is administered by the System Manager to voice 
terminals by the COR feature.
Hardware and Software Requirements

							Restriction — Voice Terminal — Pu blic
Issue  3   March 1996
3-1059
Restriction — Voice Terminal — Public
Feature Availability
This feature is available with G3i-Global and all Generic 3 V2 and later releases. 
Description
Restricts callers at specified voice terminals from receiving public network calls. 
A denied call is route d to intercept tone, a recorded announcement, or the 
attendant.
Calls c an redirect to an p ublic-restricted voice terminal. The COR of the originally 
called extension number is the only one checked.
Considerations
Public Restriction is used whenever it is necessary that users at certain voice 
terminals receive only internal calls from other voice terminals or calls extended 
from the attendant.
Interactions
The following features interact with the Restriction — Voice Terminal — Public 
feature:
nControlled Restriction
When the system authorizes a call, Controlled Restrictions are checked as 
well as those restrictions assigned b y COR.
nNight Service
The Trunk Answer From Any Station and Night Station Service features, if 
assigned to a public-restricted voice terminal, override the Public 
Restriction.
nTie Trunk A ccess
Incoming dial repeating tie trunk calls can be completed directly to an 
public-restricted extension number.
nTransfer
Incoming trunk calls can be transferred from an unrestricte d extension 
number to an public-restricted extension number.

Termination
Feature Availability
This feature is available with all Generic 3 releases.
Description
Restricts voice terminal users on specified extension numb ers from receiving any 
calls.  The restricted users can, however, originate calls.
Considerations
Termination Restriction is used whenever a voice terminal is to be used only for 
making calls.
Interactions
When the system authorizes a call, Controlled Restrictions are checked as well 
as those restrictions assigned by COR.
Administration

Ringback Queuing
Feature Availability
This feature is available with all Generic 3 releases.
Description
Places outgoing calls in an ordered queue (first-in, first-out) when all trunks are 
busy.  The voice terminal user is automatically called back when a trunk 
becomes available.  The voice terminal receives a distinctive three-burst alerting 
signal (Priority Calling) when called back.
If a multiappearance voice terminal user has an idle Automatic Callback b utton 
and tries to access an all-trunks-busy trunk group, Ringb ack Queuing is 
automatically activated, the lamp associated with the Automatic Callback button 
lights, and confirmation tone is heard. The multia p pearance voice terminal user 
must also be authorized to make the c all, Rin g back Queuing must be allowed on 
the trunk, and the trunk queue must not be full.
Ringback Queuing is automatic for a single-line voice terminal. After dialing is 
complete, the user hears confirmation tone if the queue is available.  No action is 
required by the voice terminal user.  The user hangs up and waits for callback.
The callback call is automatically placed to the terminal when a trunk becomes 
available. When the user answers the callback call, the original call automatically 
continues.  Redialing is not required.
Queuing can be specified for any non-DCS outgoing only trunk group, or for the 
outgoing direction of a non-DCS 2-way trunk group.
Considerations
With Ringbac k Queuing,  users do not have to keep trying to access a trunk 
group when all trunks in the group are busy.  This feature provides for the caller 
of a busy trunk group to automatically be called back when a trunk b ecomes 
available.
Queuing can reduce the numb er of trunks required.
A single-line voice terminal can have only one call waiting at a time; therefore, 
Ringback Queuing is denied to these voice terminals if a call is already waiting.
A multiappearance voice terminal can have one callback call associated with 
each Automatic Callback button assigned to the terminal.
A q ueue request is canceled for the following reasons: 
						

							Ringback Queuin g
Issue  3   March 1996
3-1063
nA trunk is not available within 30 minutes.
nThe voice terminal user does not answer the callback call within the 
administered interval (two to nine ringing cycles).
nThe voice terminal is busy when the callback call is attempted.
nThe voice terminal user dials the Ringback Queuing cancellation code or 
presses the Automatic Callback button associated with the queued call.
Incoming tie trunk calls cannot queue on an outgoing trunk group. The system 
does not know the calling number and cannot originate the callback call.
The system checks the busy/idle status of the trunk group just once (immediately 
after the trunk access c ode is dialed).  If at this time all of the trunks are b usy, the 
call is put into queue, even if a trunk has become available by the time the caller 
has completed dialing the numb er. This occasionally results in the caller being 
called back immediately after receiving confirmation tone and  going on-hook.
At times, a trunk appears to be available, but outgoing calls are still placed in a 
queue.  In this case, a trunk is not free, but is b eing reserved for a previous 
Automatic Callback request.
Interactions
If Ring back  Queuing is provid e d, Automatic Callback must also be provided.  
Automatic Callback is administered through the Class of Service.
Ringback Queuing affects the following features:
nARS 
If a multiappearance voice terminal user has an Automatic Callback 
button, makes an ARS call, and all trunks are busy, Ringbac k  Queuing  is 
activated automatically.
nBrid ged Call Ap pearance
Ringback Queuing is not provided on calls originate d from a bridged call 
appearance.
nCall Coverage
Callback calls do not redirect even if Send All Calls is activated.
nCall Forwarding All Calls
Callback calls are not forwarded.
nCall Pickup
Callback calls cannot be picked up. 
						

							Feature Descriptions

nConference or Transfer
A single-line voice terminal cannot receive a callback call while it has a 
call on hold and can have only one active call at a time.
nInternal Automatic Answer (IAA)
Automatic calls generated by Rin g back Queuing are not eligible for IAA.
nRemote Access
A callback call cannot be made to a Remote Access user because the 
system does not know the calling number.
Administration
Ringback Queuing is administered by the System Manager.  The following items 
require administration:
nCallback call no-answer time-out (from two to nine ringing cycles)
nAutomatic Callback button (per multiappearance voice terminal)
nRingback Queuing cancellation c o de
nQueue length (p er outgoing trunk group)
Hardware and Software Requirements
No a d ditional hardware or software is required. 
						

							Ringer Cutoff
Issue  3   March 1996
3-1065
Ringer Cutoff
Feature Availability
This feature is available with all Generic 3 releases.
Description
Allows the user of a multiappearance voice terminal to turn certain audible 
ringing signals on and off. Visual alerting is not affected by this feature.
When this feature is enabled, only Priority ring (three-burst ringing), Intercom 
ring, and Manual Signaling rings at the voice terminal.  One-b urst, two-burst, and 
redirection notification does not ring. When this feature is disabled, the voice 
terminal has normal ringing.
Table 3-74 summarizes the call types affected by the activation of Ringer Cutoff. 
The type of ring depends on whether Redirect Notification is active.
NOTE:
If Call Coverage is set to ‘‘Cover All’’  and Ringer  Cutoff  and Re direct 
Notification are both active,  then there is no audible alerting.
There are occasions when a user does not wish to be disturb e d by the arrival of 
incoming calls, and does not want the call to be immediately redirected to 
Table 3-74. Summary of Call Types Affected by Ringer Cutoff
Will The Voice Terminal Ring 
If Ringer Cutoff Is Active?
Redirect Notification =

coverage. For example, an executive may have a secretary who has bridged call 
appearances of his or her extension. If the executive does not wish to be 
disturbed, this feature can be used to allow the secretary a chance to answer the 
incoming call before it redirects to c overage. The  bridging user (the secretary) is 
not affected by the executive’s activation of Ringer Cutoff.
If a brid ging user has Bridg e d Call Alerting administered for his or her voice 
terminal (and does not have Ringer Cutoff administered), the bridging user 
receives ringing for the principal’s call.
If a primary extension and all other users with bridged appearances of the 
primary extension activate Ringer Cutoff, an incoming call silently alerts all of 
those voice terminals before the call redirects to coverage.
To activate Ringer Cutoff, the user pushes the voice terminal’s Ringer-Cutoff 
button. The associated green status lamp then lights. This lamp  remains lighted 
until the feature is d eactivated. If the feature is activated while the voice terminal 
is ringing with a one-burst  ring, two-burst ring, or redirection notification, the 
ringer is silenced.
To deactivate Ringer Cutoff, the user pushes the active Ringer-Cutoff button on 
his or her voice terminal. The green status lamp associated with the button then 
goes dark. If the selected call is in any ringing state, the ringer returns to the 
proper audible ring. If there are no calls ringing at the voice terminal, the ringer 
remains silent.
Considerations
The Ringer Cutoff feature allows a user to turn off audible ringing on his or her 
voice terminal.
Each multiappearance voice terminal user may have one Ringer Cutoff button on 
his or her voice terminal
Interactions
The following features interact with the Ringer Cutoff feature.
nAutomatic Callback
Even if the Ringer Cutoff feature has been activated, the Automatic 
Callback call returns to the user’s voice terminal with the normal 
three-burst ring.
nBrid ging
A brid ging user is not affected by a primary extension’s activation of 
Ringer Cutoff; nor is the p rimary extension affected by the activation of 
Ringer Cutoff by a bridging user.
