Line Dialer Configuration Options — Multiport Mode l
“,” 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.
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: The range of allowable values may be restricted in some countries.
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.
Line Crnt Disc: Enab(>8msec)
Nxt Enab(>8msec) Enab(>90msec) Disable
This configuration option does not appear on Models 3920-A1-401 and 3921-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.
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.
Enable – 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.
Disable – Modem does not disconnect if it receives a continuous space from the DTE. Modem will not transmit a long
space disconnect.
NOTE: In MUX Mode all enabled DTE ports on the remote modem must be in a continuous spacing condition.
