Abstract: A method of managing data transmission is provided and includes measuring a first number of payload bits communicated over a bearer during a first time period. The first number of measured payload bits is divided by a length of the first time period to yield a short term average bit rate for the first time period. Also, a bit rate margin is added to the short term average bit rate for to yield a total bearer bit rate for the first time period. Further, a bearer bit rate can be selectively provisioned based on the total bearer bit rate for the first time period. The bearer bit rate can be provisioned based on whether the bearer is a fixed bearer or an adaptive bearer.

Abstract: A method a system for automatically controlling an adaptive interleaver involves monitoring performance parameters of a transmission system and controlling the adaptive interleaver in response to the performance parameters.

Abstract: A system for implementing multiple communication channels on a single twisted pair transmission line is disclosed. The system derives additional communication channels by way of a separate transceiver unit for each derived line. Each transceiver unit communicates in a separate predetermined frequency band. Each transceiver unit, upon connection to the transmission line, automatically utilizes the lowest unoccupied frequency band by monitoring each frequency band for the presence of signal power. Thus, as many derived lines as will be supported by the customer transmission loop can be readily added.

Abstract: A method and system for optimizing coding gain that alters the backsearch buffer length and/or the input buffer length of a decoder in response to one or more transmission performance characteristics of the system. The performance characteristics are monitored to determine the performance of the system. The measured transmission performance characteristics are used to control the lengths of the backsearch buffer and the input buffer. The measured transmission performance characteristics along with the backsearch length and/or the input buffer length are analyzed and compared with simulated decoding results. In accordance with the simulated results, the system determines the optimal size of the backsearch buffer and the input buffer needed to achieve a desired performance target. The system adjusts the size of the backsearch buffer length and/or the input buffer length to equal the determined optimal lengths.
