CCITT V.25bis Dialing Commands
Overview
This appendix describes V.25bis dialing commands and responses. CCITT V.25bis is an
international dialing protocol that permits direct and stored number dialing using DTEs in either
Asynchronous, Bisynchronous, or HDLC operating mode. The 391x Series modems support
V.25bis request and answer commands. As commands are entered from the DTE, the 391x Series
modems issue a response to the DTE which indicates if the call failed or connected, or if the
command is valid or invalid.
The following sections discuss those V.25bis commands supported by the 391x Series modems and
the response to those commands. Tables D-1 and D-2 list the V.25bis commands and response
messages.
