AT Commands, Cross-Referenced to Front Panel Options (Continued)

AT	Parameter &
Command	Option	Description

AT*FL5	=TxClk	Transmit Clock. This option applies only in SDC mode. When the Tx Clk flow control option
		is selected, the modem uses a transmit clock for flow control based on available buffer space.
		The transmit clock is stopped when the buffers are full, inhibiting the flow of data from the
		DTE. It is started again when buffer space is available. NOTE: This option is operational only
		when internal timing has been selected (Clock=Internal, AT&X).

	Hold DL Line	Hold Dial Line
		This command forces the modem to hold a dial restoral connection while testing a leased line
		connection. This command applies to modems configured for restoral.
AT*HD0	=Off	The Hold Dialine option is disabled; a dial modem configured for restoral disconnects from the
		dial line normally. A leased line modem configured for restoral disconnects from the dial line
		as soon as it connects to the leased line.
AT*HD1	=1min	A dial modem configured for restoral holds the dial line for 1 minute. A leased line modem
		configured for restoral holds the dial line for 1 minute while testing the leased line.
AT*HD2	=2min
AT*HD3	=3min
AT*HD4	=4min
AT*HD5	=5min
	DTE Ct. 141	DTE Circuit 141
		Controls whether the local DTE can send the modem into a local analog loopback by sending a
		signal on V.24 Circuit 141 (Pin 18) to the modem. The DTE must support Circuit 141 in order
		to use this option.
AT*LA0	=Off	The modem does not respond to a signal on Circuit 141 (Pin 18).
AT*LAl	=On	An off-to-on transition on Circuit 141 (Pin 18) causes the modem to initiate a local analog
		loopback test.
		An on-to-off transition onV.24 Circuit 141 (Pin 18) takes the modem out of a local analog
		loopback test.

	Line Compen	Line Compensation
		Enables the modem to compensate for the effects of low loss in the End Office-to-End Office
		connections.
AT*LC0	=Off	Disables the Line Compensation option.
AT*LC1	=On	Enables the Line Compensation option.
	DTE Ct. 140	DTE Circuit 140
		Controls whether the local DTE can put the modem into a remote digital loopback by sending a
		signal on V.24 Circuit 140 (Pin 21) to the modem.
AT*LD0	=Off	The modem does not respond to a signal on V.24 Circuit 140 (Pin 21).
AT*LDl	=On	An off-to-on transition onV.24 Circuit 140 (Pin 21) sends the modem into a remote digital
		loopback test. An on-to-off transition on V.24 Circuit 140 (Pin 21) takes the modem out of a
		remote digital loopback test.

	D to L	Dial to Leased Option, Automatic Disconnect
		Lets the modem automatically disconnect from the dial line and return to the leased line after a
		specified period.
AT*LE0	=Manual	Pressing the Talk/Data key (at the Home position) returns the modem to the leased line.
