One card acts as a receiver for the +transmitting direction on the S0 bus while the other card acts as a receiver +for the receiving direction on the S0 bus. Complete traffic monitoring is +possible using this setup. +.It Fl b +switch B channel tracing on (default off). +.It Fl d +switch D channel tracing off (default on). +.It Fl f +Use +.Ar filename +as the name of a file into which to write tracing output (default filename is +isdntrace<n> where n is the number of the unit to trace). +.It Fl h +switch display of header off (default on). +.It Fl i +print layer 1 (I.430) INFO signals to monitor layer 1 activity (default off). +.It Fl l +switch displaying of Layer 2 (Q.921) frames off (default on). +.It Fl n +This option takes a numeric argument specifying the minimum +frame size in octetts a frame must have to be displayed.
