Toll Restriction
Program 45-1 – LCR/Toll Restriction Dial Plan
4-18 Strata DK Programming 5/00
Plan 7 - (10XXX)+1+NXX+NXX/NXX
The Strata DK systems in this Programming Manual default to this plan. Used when dialing 1
before the long distance number. Call is placed to a destination outside the area code by dialing a 1
before dialing the area code.
The user places a local code plus distance call to a destination in the same area code by simply
dialing the number, without a 1 in front. The area and office codes may be interchangeable. The
system differentiates between them whenever it sees the digit 1 dialed. This plan supports five-
digit Carrier Access (CA) codes (10XXX) compared to seven-digit CA codes.
When using this plan, the system recognizes the following:
♦ If 1 is the first number dialed in an 11-digit string, the next three digits are an area code
(
+ $&+ 7 digit number). A ten-digit string is not recognized ($&+ 7 digit number).
♦ Digits 2~4 and 5~7 in an 11-digit string are NXX format and are interchangeable.
♦ The first three digits in a seven-digit string are an office code. (There is no distinction between
local call dialing and long distance dialing within the area code.)
♦ If 16-digit dialing (Area Code + 7 digits) is required to be unrestricted and routed over the
local LCR route, program the Area Code in Program 46-2~4 and Program 45-2.
Plan 8
Same as Plan 7 except a new 7-digit carrier access code must be 101YXXX format (where Y is 0,
5 or 6; X is 0 to 9).
Plan 9
Same as Plan 7 except a new 7-digit carrier access code must be 101XXXX format (where X is 0
to 9).
Area codes and office codes in XXX format (where X is 0 to 9) are allowed to be programmed in
the area code and office code tables for Toll Restriction and Least Cost Routing purposes.
Only area codes formatted N(0/1)X and office codes formatted NNX are valid on call processing
for the old dial plans 1, 2, 3.
New area codes NXX are valid only in NANP dialing plans 7, 8, 9.
Office codes of the form NNX and NXX are valid on call processing for the old dialing plans 1, 2,
3, and new dialing plans 7, 8, 9, respectively. For international calls, area code 011 and office
codes XXX (as country codes) are valid on the call processing for all dialing plans.
