1 ms intervals.
Direct
Direction of frame; possible values are Xmit (transmitted by module)
and Rcvd (received by module).
SAPI

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

0 indicates a command and 1 indicates a response. For network side,
0 indicates a response and 1 indicates a command.

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.
