Introduction

This chapter describes how to use the MultiModemII modem on a 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 auto- matically 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.

In the event of an interruption, leased line modems automatically reconnect when the data line or power is restored. The MT5600BL modem also supports dial backup, which enables the modem to automatically switch to a dial-up connection if the leased line goes down.

The MT5600BA modem supports two-wire leased-line operation, while the MT5600BL modem supports both two-wire and four-wire leased line operation.

Two-Wire Setup

1.For two-wire leased line operation on the MT5600BA modem, connect the pro- vided modular telephone cable to the LINE jack. For two-wire leased line op- eration on the MT5600BL modem, connect the provided modular telephone cable to the LEASED jack. Connect the other end of the cable to the two-wire leased line jack or terminals supplied by the telephone company.

Note: One of the modems in a leased line pair must be configured as the origi- nate modem, and the other as the answer modem, but it does not matter which is which.

9.The OPTION SET screen appears. Press to exit to the ONLINE OPTIONS screen, or to exit to the CURRENT SETTING= screen to verify the selection.

10.Configuration for two-wire leased line operation is now complete. The modem immediately attempts to connect to the modem at the other end of the leased
