1. Show
the 4B/5B encoding, and the resulting NRZI signal for the following bit
sequence.
1110 0101 0000 0011
2. Assuming
a framing protocol that uses bit stuffing, show the bit sequence transmitted
over the link when the frame contains the following data. Mark the stuffed bits.
1101 0111 1101 0111 1110 1011 1111 10
3. Assuming
a framing protocol that uses bit stuffing, the following bit sequence is
received.
1101 0111 1101 0111 1100 1011 1110 110
Show the resulting frame after any stuffed bits have been removed. Indicate any errors that might have been
introduced into the frame.
4. What bit sequence should never appear in an HDLC information bit stream?
