Line Dialer Configuration Options Ð Singleport Mode A

BusyTone Detect: Enable

Nxt Enable Disable

Busy Tone Detect. Sets the modem to monitor for Busy Tone (Enable) or ignore Busy Tone (Disable).

NOTE: This configuration option is normally enabled; however, if the modem receives false busy tones, this configuration option can be disabled and the modem ignores all busy tones.

The AT commands for Disable are X0, X1, and X2.

The AT commands for Enable are X3, X4, X5, X6, and X7.

ª,º Pause Time: 2sec

Nxt 2sec 4sec 6sec 8sec 10sec 20sec

Pause Time. Determines the number of seconds the modem pauses when it encounters a comma (,) in the dial command string.

NOTE: Although DCP selections are limited (2, 4, 6, 8, 10, or 20), values set by the AT commands can display from 0 to 255 seconds.

The AT command is S-Register S8=n, where n is from 0 to 255 in 1-second increments.

NoAnswer Timout: 45sec

Nxt 45sec 30sec 60sec

No Answer Abort Time-out. Determines the number of seconds an originating modem waits before abandoning a call attempt when no answer tone is received.

NOTE: Although DCP selections are limited (30, 45, or 60), values set by AT commands can display from 1 to 255 seconds.

NOTE: The range of allowable values may be restricted in some countries.

The AT command is S-Register S7=n, where n is from 1 to 255 in 1-second increments.

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 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 3920Plus-A1-401 and 3921Plus-B1-001.

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 to Enab(>8msec).

Disable ± 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.
