Leased Line Handshaking

In a typical dial-up connection, the originating modem dials the number and waits for the answering modem's carrier signal. The answering modem can be commanded to either answer the call immediately, or after a specified number of rings.

In a leased-line connection, the communication circuit between two modems is always present. Dialing and waiting for rings does not occur in this situation. If these two modems want to establish a data link, one must be designated as the originator and the other as the answerer. You can set this manually or automatically.

Manual Connect

Set the modem to leased-line mode. Type the asynchronous command ATD to the originating modem and ATA to the answering, or press O on the RS1612 control panel for originating mode and then press A for answer mode. Use AT*Mn or set S14b0 to select originate or answer mode.

Auto Handshake

If you want handshaking to occur automatically upon power-up, you have to save the leased-line configuration to the power-on profile. Remember to set the handshake mode before you save the
