V.25 bis Protocol Overview

This chapter describes the operating procedures for the Dual V.34 Modem when using the
ITU-T (formerly CCITT) V.25 bis compatible command protocol. Although the AT command set
is the primary command set for configuring the modem, the modem provides an enhanced ITU-T
V.25 bis command protocol that permits you to configure modem dial parameters and establish data
communications.
After configuring the modem by using the AT command set, use the
V.25 bis command set.
