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.

HDisable

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.

HEnable

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 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

This configuration option does not appear on Models 3910-A1-401 and 3911.

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.

HEnable > 8-millisecond

Disconnects the modems if line current is disrupted for more than 8 milliseconds.

HEnable > 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 to Enab(>8msec).

HDisable

Ignores any disruptions in line current such as call waiting.

The 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 before it goes on-hook. Issuing a long space is one method of disconnecting a call.

HEnable

Modem disconnects if it receives a continuous space from the DTE. For modulations lower than 4800 bps, the modem’s transmitter will transmit 4 seconds of long space upon a disconnect.

HDisable

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

The AT command for Disable is Y0.

The AT command for Enable is Y1.
