Night Service with Outward Restriction 4
Apply to: Whole system
Use with: Night Service Emergency List and Night Service Exclusion List.
Includes emergency numbers (including, for example, the number
dialed by a HotLine) that can be dialed regardless of restrictions. No
password is required.
When the Password option of the Night Service feature is programmed, outgoing
calls can be restricted by requiring the user to enter a password. The operator
who turns Night Service on and off must also enter a password.
A Night Service Exclusion List exempts certain extensions (a HotLine, for
example) from the password requirement. Normal calling restrictions, however,
are still in effect.
NOTE:
For more information about Night Service, see the
Feature Reference

‘‘
Covering Calls’’ on page 4-32, and ‘‘Night Service Groups’’ on page 4-50.
Pool Dial-Out Code Restriction 4
Apply to: Extensions and remote access barrier codes, in Hybrid/PBX mode only
Use with: Any other restrictions
This restriction prevents an extension from dialing specific pool dial-out codes.
This restricts outgoing calls from specific pools and can be used to reserve pools
for specific purposes, for example, data communications. Beginning with Release
3.1, the default setting for this restriction is on; no extension or remote access
user with a barrier code has access to pools until the restriction is removed.
Facility Restriction Levels (FRLs) 4
Apply to: Extensions in conjunction with lines/trunks, in Hybrid/PBX mode only
Use with: Any other restrictions. Use Disallowed Lists if an FRL is unrestricted,
and Allowed Lists if an FRL is highly restricted, especially for
emergency numbers. Not necessary for remote access trunks if barrier
codes are used. Can be used on all tie trunks.
Automatic Route Selection (ARS) is a Hybrid/PBX mode feature where the
system is programmed with dialing plans (called
routes
) that specify certain
lines/trunks or network services for outgoing calls, and can choose the most
economical facility for a given call at a given time of day. Facility Restriction
Levels (FRLs) are assigned to specific routes in an ARS table. There are seven
different FRLs that can be assigned to routes, ranging from 0 to 6, where 0 is the
least restricted and 6 is the most restricted.
