Abstract: An integrated digital subscriber line transceiver includes a single integrated circuit that has a digital signal processing engine, a time division multiplexing framer (for example, a T1/E1 framer), and a static random access memory. The integrated circuit also includes a microprocessor coupled to the digital signal processing engine, the time division multiplexing framer, and the static random access memory. The digital signal processing engine, in one embodiment, includes an HDSL2/G.SHDSL data pump and an HDSL2/G.SHDSL framer.

Abstract: An apparatus and method are described that allows for improved wander jitter reduction in communication devices and associated communication links, in particular on HDSL communication devices and links. The improved device apparatus and method detects the current data rate offset of the HDSL data rate being utilized and the data rate of the datastream being transmitted through the HDSL communication link and allows for the transmitting HDSL communication device to adjust the HDSL data rate to avoid high wander jitter “sweet spots”. The improved device apparatus and method also allows for the profiling of communication devices for their specific high wander jitter sweet spot maximum points by sweeping the input data rate being transmitted at differing HDSL data rates.

The improved device apparatus and method detects the current data rate offset of the HDSL data rate being utilized and the data rate of the datastream being transmitted through the HDSL communication link and allows for the transmitting HDSL communication device to adjust the HDSL data rate to promote instantaneous data rate offsets that are close to wander jitter minimum points. The improved device apparatus and method also allows for the characterization of communication devices for their specific wander jitter low activity points by sweeping the input data rate being transmitted at differing HDSL data rates.
