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.
