A TDM system has five 64 Kbps sources and one 56 Kbps source. Pulse stuffing is used to match the lower rate source to the others. The frames generated by the system have 1 extra bit for synchronization 6. a. To have the extra dummy bit(s) always appear in every frame and always in the same position in the frame, what is the size of the smallest possible frame in bits? b. What is the frame rate? c. What is the duration of a frame? d. What is the data rate? e. What percent of the frame is overhead
