BSMI Debugging

	Table 2. Trace Report Values
Value	Meaning
Ch#	Lapdid number. This is an even number where
	0=Port A
	2=Port B
Time	Hexadecimal timestamp incremented at 1 ms intervals.
Direct	Direction of frame; possible values are Xmit (transmitted by module)
	and Rcvd (received by module).
SAPI	Service Access Point Identifier which identifies the type of D-channel
	signaling performed; possible values are 00 (ISDN call control) or 63
	(management procedures).
TEI	Terminal Endpoint Identifier that identifies a particular endpoint
	device.
C/R	Command/Response bit that identifies the frame as either a command
	(C) or response (R); possible values vary depending on whether the
	module is performing user side or network side signaling. For user side,
	0 indicates a command and 1 indicates a response. For network side,
	0 indicates a response and 1 indicates a command.
Type	Q.921 UNKNI message frame for unknown information frames or the
	Q.931 message contained in the I (information) frame.
N(s)	Sequence number assigned to the frame sent by the transmitting
	device.
N(r)	Expected sequence number of the next frame to be received from the
	transmitting device.
P/F	Poll/final bit which indicates the device is polling for a response from
	the other end, sending a final frame in response to a command, or
	neither. Possible values are 1 (polling for response or responding to
	command) or 0 (not polling or unsolicited response).
	If the message frame is a command (based on the C/R bit), this is a Poll
	bit; if the message frame is a response, this is a Final bit.
Size	Number of bytes in frame (shown in hexadecimal).
