About the Leased-Line Operation Feature

The MultiModemIND can be used on a two-wire leased line.
A leased line is a private, permanent telephone connection between two points. Unlike normal dialup connections, a
leased line is always active. The modems automatically connect when they are attached to the line and are turned
on. Because a leased line is always active, one of the two modems on the line must be configured as the originate
modem and the other as the answer modem; however, it does not matter which is which.
You must enter these commands in your communication program's terminal window.
In the event of an interruption, leased-line modems automatically reconnect when the data line or power is restored.

Setup

1. Connect a modular telephone cable to the LINE jack. Connect the other end of the cable to a two-wire
lease-line jack or terminals supplied by the telephone company.
2. Turn on the modem.
3. To configure a modem as the originating modem, use this AT command:
AT&L1&W fro L-L Orig
4. To configure a modem as the answering modem, use this AT command:
AT&L2&W for L-L Ans
