SBX IP 320 Features & Operation Guide

Least Cost Routing (LCR)

LCR is a system programmable feature that automatically selects 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 ways to activate LCR:

Internal LCR - If dialed digits match an internal LCR code, the system secures a CO Line from

the programmed CO Group and sends the modified digits according to LCR programming.

Loop LCR - When dialing the first accessible CO Group Code (9 or 0), or pressing the [Loop]

button, if the dialed digits match a COL LCR code, the system will secure a CO Line from the

programmed CO Group and send the modified digits according to LCR programming.

Direct CO LCR - After dialing a CO Line or CO group code (9 or 0, depending on the nation

you are calling from), or pressing a CO Line or CO group button, LCR can be activated. If the

dialed digits match a COL LCR code, the system will secure a CO Line from the programmed

CO group and send the modified digits according to LCR programming.

When a user selects a CO Line and dials a destination number, the system checks the LCR

programming and sends the call according to the least cost route according to the ADMIN

program.

Operation

To activate Internal LCR:

Dial the internal LCR Code after lifting the handset or pressing the [SPEAKER] button

(on-hook dialing can also activate LCR). It is an internal LCR Code if the code is

programmed with internal or both in the Leading Digit Table.

To activate Loop LCR:

1. Dial COL LCR code after dialing the first accessible CO Line or CO Group access code

(0 or 9), or press the [Loop] button.

2. It is a COL LCR code if the code is programmed with COL or BOTH in the Leading

Digit Table.

To activate Direct CO LCR:

Dial the COL LCR code after dialing a CO or CO Group Access code, or press a CO or

CO Group button. It is a COL LCR code if the code is programmed with COL or BOTH

in the Leading Digit Table.

Ex. 1 Add Prefix Digit - The long distance call access code starts with 0 (e.g., 02, 031, 051). If

a cheaper carrier exists, the user can access it with the carrier access code 082 and the long

distance access code without 0.
