  + 3.1.2 + Time-division multiplexing 
+ + + + + + +
+ + Time-Division Multiplexing (TDM) is the + transmission of several sources of information using one common + channel, or signal, and then the reconstruction of the original + streams at the remote end.

+ + In the example shown in the first figure, + there are three sources of information carried in turn down the output + channel. First, a chunk of information + is taken from each input channel. The size of this chunk may vary, but + typically it is either a bit or a byte at a time. Depending on whether + bits or bytes are used, this type of TDM is called bit-interleaving or + byte-interleaving. +

+

+ + Each of the three input channels has its + own capacity. For the output channel to be able to accommodate all the + information from the three inputs, the capacity of the output channel + must be no less than the sum of the inputs.

+

+ + In TDM, the output timeslot is always + present whether or not the TDM input has any information to transmit. + TDM output can be compared to a train with 32 railroad cars. Each is + owned by a different freight company and every day the train leaves + with the 32 cars attached. If one of the companies has product to + send, the car is loaded. If the company has nothing to send, the car + remains empty, but it is still part of the train.

+

+ + TDM is a physical layer concept, it has no + regard for the nature of the information that is being multiplexed onto the output channel. TDM is independent of the Layer 2 + protocol that has been used by the input channels.

+

+ + One TDM example is Integrated Services + Digital Network (ISDN). ISDN basic rate (BRI) has three channels + consisting of two 64 kbps B-channels (B1 and B2), and a 16 kbps + D-channel. The TDM has nine timeslots, which are repeated. + This + allows the telco to actively manage and troubleshoot the local loop as + the demarcation point occurs after the network terminating unit (NTU).
