communications (PDH) A transmission system for voice
communication using plesiochronous synchronisation.
PDH is the conventional multiplexing technology for network
transmission systems. The transmitter adds dummy information
bits to allow multiple 2-Mbit/s channels to be bit
interleaved. The receiver discards these bits once the
signals have been demultiplexed. [Is this correct?]
