(c) the duration of a time slot and
(d) the duration of a frame.
Ans: (a) The duration of one bit before multiplexing is 1/1 kbps, that is, 0.001 s or 1 ms.
(b) The transmission rate of the link will be five times the data r te of the connection, that is, 5 kbps.
(c) The duration of a time slot will be one-fifth of the duration of each bit before multiplexing,
that is, 1/5 ms or 200 μs.
(d) Since there are five slots in a frame, the duration of a frame will be equal to five times the
duration of a time slot, that is, 5 × 200 μs or 1 ms.
