Auto Start-up Does Not Automatic detection of the line type (LineType=Auto) and link protocol Include Async (OWNer=Auto) do not include recognition of Async PPP and AT dial. For Async PPP

and AT dial (which must be used together), the following parameters must be explicitly configured:

-PATH LineType=Dialup

-PATH DialMode=ATdial

-PATH ExDevType=Async

-PORT OWNer=PPP

The PATH service parameter TransferMode should not be changed from its default value of AUto. Other settings of this parameter are reserved for future extensions.

Bandwidth-on-Two PORT Service parameters are used to configure bandwidth-on-demand ports. Demand Timer The DialIdleTime parameter sets the time in seconds before all dialup lines in a

Precedence port are disconnected if the port is not in use. The DialSamplPeriod parameter sets the time (in seconds) to sample before taking an action to bring additional paths up or down, based on traffic load for bandwidth-on-demand. The value specified for the DialIdleTime parameter takes precedence over the value specified for the DialSamplPeriod parameter.

	■	1200	■	112 K
	■	1800	■	128 K
	■	2400	■	256 K
	■	3600	■	384 K

If you configure a baud rate that is different from those listed, the system will fall back to the nearest lower supported rate.
