Chapter 4 - Leased Line Operation
29
Multi-Tech Systems, Inc. MT5600BA/BL Series User Guide
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 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.
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.
1. For two-wire leased line operation on the MT5600BA modem, connect the
provided modular telephone cable to the LINE jack. For two-wire leased line
operation 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.
2. Turn on the modem.
3. Starting at the STATUS screen, press the following buttons on the front panel:
â, à, â, â, â, à. The CURRENT SETTING= screen appears.
4. If the CURRENT SETTING= screen shows ASYNC AT, press á

step 7. If it shows anything else, press à to go to the ASYNC, NORM? screen.
5. Press the Enter button to select normal asynchronous operation.
6. The OPTION SET screen appears. Press á

to exit to the SYNC/ASYNC
OPTIONS screen.

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 à to display the 2 WIRE
LEASE? ANSWER screen, 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 screen appears. Press á
ß
to exit to the ONLINE OPTIONS
screen, or à to exit to the CURRENT SETTING= screen 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.
