Restrictions — Individual and Group-Controlled
(DEFINITY ECS, DEFINITY G1, G3, and
System 75)
For DEFINITY ECS, DEFINITY G1, G3, and System 75, individual and
group-controlled restrictions allow an attendant or voice terminal user with
console permission to activate and deactivate the following restrictions for an
individual terminal or a group of voice terminals:
 Outward — The voice terminals cannot be used for placing calls to the
public network. Such call attempts receive intercept tone.
 Total — The voice terminals cannot be used for placing or receiving calls.
DID calls are routed to the attendant or a recorded announcement. All
other calls receive intercept tone. As an exception, the following call types
are allowed: calls to a Remote Access extension, terminating trunk
transmission tests, and Emergency Access to Attendant calls.
 Station-to-station — The voice terminal cannot receive or place
station-to-station calls. Such call attempts receive intercept tone.
 Termination — The voice terminal cannot receive any calls. Incoming calls
are routed to the attendant, are directed via Call Coverage, or receive
intercept treatment.
All voice terminals with the same COR are affected by a group restriction. When a
call is placed, both the individual and group restrictions are checked.
To activate the desired Controlled Restriction, the attendant or voice terminal user
with console permission dials the feature access code for either the extension or
the group, followed by either 1 for Outward, 2 for Total, 3 for Termination, or 4 for
Station-to-Station, and then dials the voice terminal extension number (Attendant
Control — Extension) or the COR for a group of voice terminals (Attendant
Control — COR).
This feature is especially helpful in businesses such as hotels, where you might
want to restrict phones in empty conference rooms or in guest rooms after a client
has checked out. You might also want to restrict phones in an entire wing of a
building at times.
Central Office Restrictions
Some Central Offices offer additional services that screen long distance calls,
such as 0 + calls and 101xxxx+ calls. Contact your local telephone company for
details.
