Overview
ITU-T 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 Model 3830 modem
supports 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, the 3800 Series modems issue a response to the
DTE which indicates if the call failed or connected, or if the command
is valid or invalid.
