摘要
An apparatus (200) and method are provided for data transmission and data reception over telephony channels in a cable communications environment. The apparatus (200) includes a cable network interface (210) coupleable to a communications channel (103 see Fig 1) for data transmission and reception utilizing a first protocol; a processor arrangement such as a microprocessor subsystem (235); and a user modem interface (250). The user modem interface (250) and the processor arrangement are responsive when operably coupled, through a set of program instructions, to establish a communications connection and determine whether the communications connection is direct digital; when the communications connection is direct digital, the user modem interface (250) is further responsive to transfer data to the processor arrangement and the cable network interface (210) to process data in a digital mode for data transmission and data reception; and when the communications connection is not direct digital, the user modem interface (250) and the processor arrangement are further responsive to process data in an analog mode for data transmission and data reception.
