Chapter 4 - Leased Line Operation

This chapter describes how to use the MultiModem II 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 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; 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 modem also supports dial backup, which enables the modem to automatically switch to a dial-up connection if the leased line goes down.

The modem supports both two-wire and four-wire leased-line operation.

Two-Wire / Four-Wire Setup

1.For leased line operation, plug one end of a two-wire phone cable into the modem’s LEASED jack. Connect the other end to a leased line wall jack or terminals.

2.Turn on the modem.

3.Starting at the STATUS LCD, press the following buttons on the front panel: È, Æ, È, È, È, Æ. The CURRENT SETTING= LCD appears.

4.If the CURRENT SETTING= LCD shows ASYNC AT, press ÇÅ and go to step 7. If it shows anything else, press Æ to go to the ASYNC, NORM? LCD.

5.Press the Enter button to select normal asynchronous operation.

6.The OPTION SET LCD appears. Press ÇÅ to exit to the SYNC/ASYNC OPTIONS LCD.

7.Press ÇÅ, ÇÅ, ÇÅ, Æ, Æ, Æ, Æ. The 2 WIRE LEASE? ORIG LCD appears.

8.Choose one of two actions:

•To set up the modem as the originate modem, press the Enter button.

•To set up the modem as the answer modem, press Æ to display the 2 WIRE LEASE? ANSWER LCD, and then press the Enter button.

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

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

10.This completes the setup for two-wire leased line operation. Upon completion, the modem attempts to connect to the modem at the other end of the leased line. If the remote modem has not yet been configured for leased line operation, you may turn off the local modem until the remote one is ready.
