2.2.7 LCR (Least Call Routing)
Description
LCR is a system programmable feature that is automatically selected the least expensive available
route when an outgoing CO call is made. This programming eliminates the necessity for the user to
dial the access code of the least expensive carrier. There are three types of operation to activate
LCR;
Internal LCR
- It can be activated during internal dial tone. If the dialed digits are matched with
internal LCR code, the system will seize a CO Line from the programmed CO group and send the
modified digits according to LCR programming.
Loop LCR
- It can be activated by dialing the first accessible CO group code ('9' or '0') or by pressing
Loop button. If the dialed digits are matched with COL LCR code, the system will seize a CO Line
from the programmed CO group and send the modified digits according to LCR programming.
Direct CO LCR
- It can be activated during CO dial tone. After dialing CO Line or CO group code( 9
or 0, depend on nation), or pressing CO Line or CO group button, it can be activated. If the dialed
digits are matched with COL LCR code, the system will seize a CO Line from the programmed CO
group and send the modified digits according to LCR programming.
The following figure 2.2.7 describes LCR.
When a user seizes CO Line and dial destination number, the system checks the LCR programming
and send the call to least cost route according to the ADMIN program.
Assuming LCR code is ‘9’, the 001 network is least cost during the daytime, and the 002 network is
least cost during the night. Caller dials same number and system routes it through least cost network.
