An Overview of Toll Restrictions
FF7
Notes:
Operator Calls. Under the old dialing plan, operator calls for TRS types 3-6
are permitted if international calls are permitted system-wide (FF7 l# l# l#).
The Office Code Tables (FF7 3#) are used to restrict all 0+ dialing; the next
two digits will also be analyzed. (Operator calls are always restricted for TRS
types O-2 -- and always allowed for TRS type 7.)
Under the new NAiVP dialing plan, operator calls can be allowed or restricted
on individual extensions (using FF'7 l# 17#), as long as the extension uses a
trunk assigned TRS type 2-6. (Operator calls are always restricted for TRS
types 0 and 1 -- and always allowed for TRS type 7.)
Area Codes and O@ce Codes. Under either dialing plan, outgoing calls on
trunks assigned TRS types 3-6 can be allowed or restricted based on the area
code and/or office code dialed. When a number is dialed, the system first
checks arealofice code combinations entered in the "Special Area Code/
Office Code Tables" (FF7 4# and 5#). If it doesn't find any restrictions there,
the system then checks the office codes assigned to TRS types 2-6 as a group
(FF7 l# 21#) -- if the system is programmed to use the new NANP dialing
plan. If not (or if the system doesn't find a match), it then checks the
individual area codes and office codes assigned to individual TRS types in
FF7 2# and 3#.
International Calling. Under the old dialing plan, international calls are
allowed or restricted on a system-wide basis using the TRS type assigned to
the trunk. Under the new NANP dialing plan, international calls on trunks
assigned TRS types 3-6 can be allowed or restricted on individual extensions
(FF7 l# 18#). Furthermore, these extensions can also be programmed to
allow or restrict individual calls based on the Country Code dialed (FF7 l# 1#
and FF-7 l# 19#).
