Overview

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 3800Plus modems support V.25bis request and answer commands that initiate and cancel dialing, program commands that allow you to create and enter telephone numbers to memory, and list commands that display all telephone numbers stored in directory locations. As commands are entered from the DTE,

3800Plus 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 section discusses those V.25bis commands supported by 3800Plus modems and the response to those commands.

Tables F-1 and F-2 in the Command Response section list the V.25bis command and response and the analogous AT command.

NOTE

The 3800Plus modem must be configured for V.25bis dialing. Refer to DTE Dialer Type configuration option in Chapter 8, Configure Branch.
