Configuring the POCKET ISDN-TA
**DTE
Selects the Layer 2 link addresses. Only valid for protocols that are HDLC based
(X.75, LAPB).
AT**DTE=0 Calling side reacts as DTE,
called side reacts as DCE (default, X.75 standard)
AT**DTE=1 TA reacts as DTE (own adr = 01)
AT**DTE=3 TA reacts as DCE (own adr = 03)
Note: The value will be changed by setting the B channel protocol (ATBx).
**ISDN
Selects ISDN D channel protocol to the ISDN line. The protocol must fit the protocol
running on the ISDN line otherwise a connection cannot be set up.
Note: after changing and storing the ISDN protocol the POCKET ISDN-TA has to be
reset by powering it off and on (alternately you can use the command
AT&W**RESET).
