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

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

neither. Possible values are 1 (polling for response or responding to
command) or 0 (not polling or unsolicited response).

the message frame is a response, this is a Final bit.
