modulation schemes. Microcom employed a variation of V.29 modulation which is half-duplex 9600 bit/s. MNP 6 utilized the compression of MNP 5, and with the fast training capability of the Rockwell V.29 devices. the AX/9624c achieved full-duplex 9600 bit/s at a price lower than its competitors. Like other 9600 bit/s modems, it was required to have the same hardware on both ends of the link, however, the modem also supported V.22bis at 2400 bit/s.

Microcom introduced a new series of
