Chapter 4 - Leased Line Operation

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.
