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.

NOTE

The 391x Series modem must be configured for V.25bis dialing.
