east Cost Routing (LCR)
Description
3-78
Features
Least Cost Routing (LCR) is a system programmable feature that
automatically selects the least expensive route available at the time
a long distance call is made. Previous programming eliminates the
necessity for the user to dial the access code of the least expensive
carrier. The appropriate CO line group is selected and an
appropriate access code is added before the number is outpulsed.
General Description
The dialling plan for long distance call is as follows:
01NX-NXX-XXXX
01NXX-NXXXXX
(N=2-9; X=0-9)
<Example>
London
Birmingham
Edinburgh
Glasgow
Liverpool
Manchester
Tyneside
Wearside
Other Areas
The charged fee is decided by three digits (NXX) following "0" of
the area codes and time zone per carrier. For example, if charged
fee by a carrier is as follows, program the carrier's fee in time
zones. The system compares each carrier's charged fee and selects
the least expensive carrier for the call.
