Restriction — Miscellaneous Terminal
Feature Availability
This feature is available with all Generic 3 releases.
Description
Restricts callers at specified voice terminals from accessing certain other voice 
terminals.
Misc ellaneous Terminal Restrictions can be used whenever it is undesirable for 
users at certain voice terminals to access other specific voice terminals.
Considerations
The Miscellaneous Terminal Restriction is controlled by the COR assigned to the 
calling voice terminal user and to the voice terminal being called. Any COR can 
be a dministered to allow or deny access to any other COR. Restricted calls are 
routed to intercept tone.
Interactions
A voice terminal user with authorization to access an Ab breviated Dialing 
Privileged Group Number List or Privileged System Number List can place calls 
to any number on that list.  COR assignments are not checked.
Administration
Misc ellaneous Terminal Restriction is administered via the COR feature by the 
System Manager.  The only administration required is the permission for each 
COR to access other CORs.
Hardware and Software Requirements
No a d ditional hardware or software is required.

Restriction — Miscellaneous Trunk
Feature Availability
This feature is available with all Generic 3 releases.
Description
Restricts users at specified voice terminals from accessing certain trunk groups, 
such as WATS.
For a  detailed description of Miscellaneous Trunk Restrictions, see the Class of 
Restriction (COR) description.
Considerations
Misc ellaneous Trunk Restriction can be used whenever it is necessary to restrict 
users at certain voice terminals from accessing specific trunk groups.
The Miscellaneous Trunk Restriction is controlled by the COR assigned to the 
calling voice terminal user and to the trunk group being accessed. Any COR can 
be administered to allow or deny access to any other COR. Restricted calls are 
routed to intercept tone.
Interactions
The following features interact with the Restriction — Miscellaneous Trunk 
feature.
nAbbreviated Dialing
A voice terminal user with authorization to access an Ab breviated Dialing 
Privileged Group Number List or a Privileged System Number List can 
place calls to any number on that list.  COR assignments are not checked.
nARS 
This feature overrides the Miscellaneous Trunk Restriction feature.  
Permission or denial of ARS  calls is determined by the FRL.
Administration
Misc ellaneous Trunk Restriction is administered via the COR feature by the 
System Manager.  The only administration required is the permission for each 
COR to access other CORs.

Restriction — Toll
Feature Availability
This feature is available with all Generic 3 releases.
Description
Restricts users at specified voice terminals from placing calls that have been 
designated as toll calls by system administration.
With the Toll Restriction feature, a Toll Analysis table can be administered to 
assign certain d ialed digit strings to a ‘‘toll list.’’ A call containing one of the 
dialed digit strings assigned to the toll list is designated as being a ‘‘toll call.’’
When a user attempts to dial a toll call, as defined in the Toll Analysis table, he or 
she may or may not b e able to p lace the call, depending on his or her assigned 
COR:
a. If the user has a COR with a calling party restriction of ‘‘All-Toll,’’ that user 
is prevented from making ARS or CO/FX trunk access calls to certain toll 
areas as d efined in the Toll Analysis table, unless the number is on an 
UCL associated with the user’s COR. (Information on Restricted and 
Unrestricted Call Lists is provided in the COR feature description 
elsewhere in this manual.)
b. If the user has a COR with a calling party restriction of ‘‘TAC-Toll,’’ that 
user is prevented from making trunk access calls to certain toll areas as 
defined in the Toll Analysis table, unless the numb er is on an UCL 
associated with the user’s COR. TAC-Toll restrictions are included with the 
All-Toll calling party restriction. The only difference is that All-Toll also 
a p plies to ARS calls.
If a user is restricted from making an attempted toll call, the user receives 
intercept treatment.
If the system is connected to a CO that uses a step-by-step switch, all seven 
digits which are normally dialed for a local call may not be required by the CO to 
route the call.  For example, the central office may only require the last five of the 
normally dialed seven digits.  If all seven digits are dialed, the step-by-step 
switch uses digit absorption to absorb the unneeded digits. Digit absorption can 
be provided within the system to emulate the absorption at the central office.  
This prevents users from bypassing code and toll restriction b y d ialing unneeded 
d i gits. For exam ple, assume that the central office absorbs leading sevens 
before processing a number and that a toll-restricted user wants to dial a toll 
code of the form 1-201 plus seven more digits.  The user can dial 77-1-201 plus 
seven more digits. The Toll Restriction feature does not recognize the call as a 
toll call and the central office routes the call. With digit absorption, the 77 is  
						

							Restriction — Toll
Issue  3   March 1996

absorbed by the system before Toll Restriction is used.  Thus, the call is denied, 
as intend e d. Up to five d i git absorption lists can be assigned.
If digit absorption is administered, 0/1 toll restriction is used to determine whether 
or not the call is allowed.  The Toll Analysis table is not checked.
Considerations
Toll Restriction is used whenever it is necessary to restrict users at certain voice 
terminals from making toll calls.  The customer can define what numbers are to 
be considered toll calls.
One toll list can be assigned per system.
Dialed Digit Strings administered as toll calls in the Toll Analysis ta ble can be a 
maximum of 18 digits in length.
The Toll Analysis table can have a maximum of 1,000 dialed string entries. Each 
entry can be assigned to the toll list. However, the 1,000 entries in this table are 
also used to assign restricted and unrestricted call lists.
Interactions
None.
Administration
Toll Restriction is administered by the System Manager, and is normally enabled 
for each of your foreign exchanges (FX) and central office (C0) trunks. This 
means that a toll-restricted user is not able to make a toll call using the trunk 
group’s TAC.  If the System Manager wishes to allow toll-restricte d users to place 
toll c alls over a particular CO/FX trunk group, the “Toll Restricted” field should  be 
set to ‘‘n.’’ The “Toll Restricted” field is ignored if the originator of the call is not 
toll-restricted.
Toll Restriction is also a dministered by the System Manager to the following by 
the COR:
nAttendant consoles as a group
nIncoming tie trunks on a trunk group basis
nVoice terminals on a per-terminal basis
nData mo dules on a per-mo dule basis
The Toll Analysis table must be a dministered by the System Manager to define 
which calls are toll calls.

The System Manager may also administer digit absorption lists containing 
absorption treatment of each digit zero through nine.
Hardware and Software Requirements
No a d ditional hardware or software is required. 
						

							Restriction — Voice Terminal — Inward
Issue  3   March 1996
3-1053
Restriction — Voice Terminal — Inward
Feature Availability
This feature is available with all Generic 3 releases.
Description
Restricts callers at specified voice terminals from receiving public network, 
attendant-originated, and attendant-extended calls. A denied call is routed to 
intercept tone, a recorded announcement, or the attendant.
Calls can redirect to an inward-restricted voice terminal.  The COR of the 
originally called extension number is the only one checked unless the three-way 
COR check on Conference and Transfer calls is provid e d (see Interactions).
Considerations
Inward Restriction is used whenever it is necessary that users at certain voice 
terminals receive only internal calls from other voice terminals.
Interactions
The following features interact with the Restriction — Voice Terminal — Inward 
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 an inward-restricted voice terminal, override the Inward 
Restriction.

nTie Trunk A ccess
Incoming dial repeating tie trunk calls can be completed directly to an 
inward-restricted extension number. However, such calls cannot be 
extend e d by an attendant to an inward-restricted voice terminal.
nTransfer
Incoming trunk calls can be transferred from an unrestricte d extension 
number to an inward -restricte d extension numb er unless the three-way 
COR check on Conference and Transfer (G3i-global and G3V2 only) is not 
overridden.
NOTE:
With G3i, G3vs/G3s, G3r, and the default o peration on G3i-global, 
G3V2, and later releases, no 3-way COR check is made.  In 
G3i-global, G3V2, and later releases, the 3-way COR check can  be 
optionally allowed for all stations and attendants, or for all stations 
only.  When a 3-way COR check is made, Incoming Trunk calls 
cannot be transferred to an inward-restricted extension number.
Administration
Inward Restriction is administered b y the System Manager to voice terminals by 
the COR feature.
Hardware and Software Requirements
No a d ditional hardware or software is required. 
						

							Restriction — Voice Terminal — Manual Terminating 
Line

Restriction — Voice Terminal — 
Manual
Terminating Line
Feature Availability
This feature is available with all Generic 3 releases.
Description
Restricts callers at specified voice terminals from receiving c alls other than those 
from an attendant. All other calls are routed to intercept tone, a recorded 
announcement, or an attendant. The voice terminal user can originate calls and 
activate features.
Calls can redirect to a voice terminal assigned this feature.  The COR of the 
originally called extension number is the only one checked.
Considerations
Manual Terminating Line Restriction is used whenever it is necessary to have 
users at certain voice terminals receive only calls from or extend e d by an 
attendant.
Interactions
The following features interact with the Restriction — Voice Terminal — Manual 
Terminating Line 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 or Night Station Service feature, if 
assigned to a restricted voice terminal, overrides Manual Terminating Line 
Restriction.
Administration
The Manual Terminating Line Restriction feature is administered by the System 
Manager to voice terminals by the Class of Restriction feature.
