Abstract: An integrated access device is automatically configured to conduct packetized voice and data communications between a customer's voice/data equipment and a digital communications switch. For this purpose, the IAD's communication control processor is programmed to perform an automated analysis of the digital communications link and thereby identify communication interface circuits such as DSLAM and voice gateway units, that have been installed by the service provider. It then automatically configures the communication parameters of the IAD for communication compatibility with the communication interface circuits.

Abstract: A byte boundary information recovery mechanism locates the first bits of respective bytes of an asynchronous transfer mode (ATM)-based serial data stream, used by a frame synchronization mechanism to delineate respective cells of the ATM stream, and thereby enables transceiver equipment to successfully receive and parse ATM traffic. The invention employs a counter offset-based scheme that generates an output signal in potential alignment with the (first bit) boundary of a byte of the data stream, in response to the contents of a counter reaching a prescribed count value. It then iteratively shifts, as necessary, the bit time at which the output signal is produced relative to the counting operation of the counter, until the output signal is aligned with the boundary of a byte of the data stream.
