FF-8 LCR mode
3 - 8 LCR
(Least
cost routinq) mode
Outside calls can be made at less cost by using MU,
SPRINT, etc. than through the ordinary ATfines.
The LCR (Least Cost Routing) function has been
devised to enable the automatic use of the
cheapest line when dialing out
A table is preparedaccording to the programming
and the line is automa tically selected by the system
searching this table when calls are made.
With this function telephone charges can be
substantially reduced, particularly in that there is a
tendency
to
make oukide calls without being
conscious of the fact.
The procedure for setting the LCR mode involves
firstly checking the cheapest trunk number when
calling at each time and in each outside line group
based on the telephone numbers of the parties to
be called. Then the order of priority fram the
point telephone call costs is determined and
stored in the table.
The following is a description of a stnrcture for a
simple LCR system.
