multiplexer system that uses multiple HDSL lines to transport Nx64 or standard
T1/E1 applications. The RS8953B’s PCM timeslot router contains 64 table entries
that extends the maximum PCM channel rate to 64x64 or 4.096 Mbps. RS8953B
allows PCM channels at the central office (CO) and remote ends to operate at
different rates. For example, the PCM channel in a digital switch may connect to a
4.096 Mbps shelf bus, while the remote terminal connects to a T1/E1 standard
PCM channel.
