Line Dialer Configuration Options

Fast Disconnect: Disable

Nxt Disable Enable

Fast Disconnect. Allows the modem to disconnect immediately after receiving a disconnect command from a local DTE or its own diagnostic control panel.

Disable – The modem follows its normal disconnect sequence by issuing a cleardown sequence or long space disconnect. This is also known as a graceful disconnect since the other modem receives advance notice of a disconnection.

Enable – Use this setting if the DTE requires that the modem be made available as soon as possible after receiving a disconnect command.

NOTE: This abrupt method of disconnecting may cause problems with the remote modem, which may interpret the disconnection as an error instead of a valid disconnect.

The factory default is Disable.

AT command is S-register S85 = n, where n is 0 for Disable and 1 for Enable.

Line Crnt Disc: Enab(>8msec)

Nxt Enab(>8msec) Enab(>90msec) Disable

Line Current Disconnect. Determines the modem’s response to short interruptions of line current. The loss of line current is one method of disconnecting a call.

Enable > 8-millisecond– Disconnects the modems if line current is disrupted for more than 8 milliseconds.

Enable > 90-millisecond– Disconnects the modems if line current is disrupted for more than 90-milliseconds. Use this setting if the modem constantly disconnects when set for Enab(>8msec).

Disable – Ignores any disruptions in line current such as call waiting.

The factory default is Enab(>8msec).

AT command is S-register S65 = n, where n is 0 for Enable (>8 msec), 1 for Enable (>90 msec), and 2 for Disable.

Long Space Disc: Enable

Nxt Enable Disable

Long Space Disconnect. Determines the modem’s response to a continuous spacing condition sent from the remote modem when it goes on-hook. Issuing a long space is one method of disconnecting a call.

NOTE: This configuration option is ignored when the modem operates in Synchronous mode or Dial Backup mode.

Enable – Modem disconnects if it receives a continuous space from the DTE. The modem’s transmitter will transmit 4 seconds of long space upon a disconnect.

Disable – Modem does not disconnect if it receives a continuous space from the DTE. Modem will not transmit a long space disconnect.

For Async Dial, UNIX Dial, and Sync Leased, Enable is the factory default.

For Sync Dial, Disable is the factory default.

AT command for Disable is Y0.

AT command for Enable is Y1.
