We have 3 information sources, generating traffic at rates 300bps, 450bps and 600 bps respectively. The sources are active 25%, 50% and 75% respectively. They are to be multiplexed using multiple-slot (each slot supporting 2 bits), synchronous TDM. Ignore any synchronization bits.

A) the minimum slots in the tdm frame is

B) the multiplexor but rate is

c) the tdm fram rate is

D_ the slot duration is

#### Homework Answers

Answer #1

Synchronous TDM:

• it is time division multiplexing
• These are used allow multiple signals to be sent over a single faster connection by sectioning a link into time slots
• Time slots are fixed
• Time is assigned to each signal dynamically

In above problem

given that

traffic rate are 300bps 400bps 600bps

Sources are active some percentages are given in the above problem

A) the minimum slots in the TDM frame is 641 bits

B) The multiplexed rate is 1600 bps

C) The frame rate is 25 frame/sec

D) The slot rate is 800 slots/sec
