Assume synchronous time division multiplexer with three inputs - channel 1, channel 2, and channel 3. The output of this multiplexer produces synchronous 18-bit frames that are provisioned for stuffing as shown in the figure. The stuffing process can occur with each frame. The output link of this multiplexer operates at 36 Mbps. Determine the upper and lower bound of data rate at each input channel.
