A time-division multiplexing system for asynchronous high-rate telemetry.
A time-division multiplexing system has been developed that is significantly different from commercially available equipments. Multiplexing is achieved by interleaving blocks of data from each source, preceded by a short coded bit pattern specifying the source of that particular block of data. Data blocks are transmitted as they become available from each particular source. Hence, synchronism of the input and output rates is not required. The prototype system can accommodate input rates as high as 461 kbit/sec on a single input channel, and output rates as high as 953 kbit/sec. The system makes possible use of an excess of 90% of channel capacity for information transmittal.
