Chapter 4 – Leased Line Operation

Four-Wire Setup

1.For four-wire leased line operation, connect one end of the four-wire cable to the LEASED jack on the back of the modem. Connect the other end of the cable to a four-wire leased line 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, Æ, Æ, Æ. The SYNC, NORM? LCD appears.

4.Press the Enter button to select normal synchronous operation.

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

6.Press ÇÅ, ÇÅ, ÇÅ, Æ, Æ, Æ, Æ, Æ, Æ. The 4 WIRE LEASE? ORIG LCD appears.

7.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 4 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.

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

9.This completes the setup for four-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.

Dial Backup

For leased line operation, the MT5600BA-V92 modem has a dial backup capability in which the modem is connected to a standard dial-up line as well as to the leased line. If the leased line fails, the originate modem automatically dials and connects to the answer modem through the standard telephone network. While it is in dial backup mode, the modem periodically checks the leased line to see if it is operational. If the line is operational, the modem then attempts to restore the leased line. If the modem detects that it is not connected to the standard telephone network when the leased line fails, it immediately switches to leased line restore.

The dial-back timer, register S17, determines how long the modem waits after a leased line failure before it attempts a dial backup connection. The S17 default setting is one minute. During that minute, the originate modem tries to establish the leased line link. If the leased line is established during that time, the S17 timer is cleared and everything is back to normal. If the timer expires, the modem attempts a dial backup connection. The purpose of the timer for the answer modem is to determine when it can accept a dial-up call. Dial-back starts only when both timers have expired and the leased line is still down.

The restore timer, register S15, determines how frequently restore attempts occur when the modems are in dial backup mode. S15 can be set from 10 to 255 minutes in one minute increments. A value of 0 disables dial backup. The default value is 30 minutes.

Notes:

•Register S15 must be set identically on the local and remote modems.

•The dial backup number must be set from the front panel of the modem.
