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).
