The apparatus and method for high speed data and command transfer over an interface (202), such as an ISA or PCMCIA bus or interface, includes a transceiver (206) and a processor (210) having a direct memory access (DMA) controller (240), a memory (211) for storage of data, and a channel interface (218) for connection to a communications channel. The processor (210) is responsive through a set of program instructions, such as software or firmware, to receive an interrupt signal (310, 315) and, when the interrupt signal indicates a write command (320, 330), to transfer data via the transceiver from the interface to the memory for transmission over the communications channel (335), and when the interrupt signal indicates data received from the communications channel (350), the processor further responsive to generate a read command and transfer data from the memory to the interface via the transceiver (355).

The apparatus (101) and method provide for data transmission capability on bonded data channels of a communications network (104), such as an integrated services digital network, utilizing a single serial communication controller ('SCC') for the bonded data channels. The apparatus (101) includes an interface transceiver (210), interface circuitry (220), and an integrated multiprotocol processor (200). The integrated multiprotocol processor (200) contains an SCC (420) which may be utilized for data transmission on bonded data channels, with other SCCs (430, 440) available for use on other channels. The apparatus and method provide for proper data alignment of primary (or master) channel data and secondary channel data on the bonded channels, through the same SCC, through utilization of a predetermined information pattern transmitted in a loopback mode (810, 820) of the interface transceiver (210), to the receiver of the SCC (830). The received information pattern is compared to the transmitted, predetermined information pattern (850). If the patterns do not match, the data for transmission is realigned for transmission in proper time division multiplexed slots for the primary and secondary channels of the bonded channel (850,860). The interface transceiver (210) may then be reconfigured for a transmission mode (845), and data transmission activities may commence.
