Abstract
A system and method for allocating signal types to transmission channels in a multi-channel, multi-signal transmission system uses one or more decision rules to determine a signal-to-channel mapping based on a predetermined performance criterion, such as signal-to-noise ratio (SNR), SNR margin, or target transport margin at a particular bit error rate (BER), rather than random assignment. The system and method improve overall performance of a transmission system carrying multiple signal types, such as telephony, compressed digital video, broadcast video, and low and high speed data. The decision rules are implemented over the entire transmission system to simplify recordkeeping and associated aspects of network operations.
