Multiplexer system providing improved bit count integrity |
摘要 |
A multiplexer system providing a transmission frame field containing information derived from the cumulative total of stuff bits used over a plurality of frames. The stuff bits which also have assigned positions in the transmission frame are generally used in asynchronous systems to compensate for the input data rate of a group not being a fixed submultiple of the transmission rate. The demultiplexer system uses the information derived from the cumulative total to improve the bit count integrity performance of data channeled out to a user device. Also, during transmission fade conditions, the demultiplexer uses information derived from the frequency of past stuff operations to maintain group bit count close to its expected value.
