Below is an example of transport characteristics of an interactive service through DCH

The below is an example of the transport characteristics of a Signaling Radio Bearer through DCH

These two DCHs are multiplexed into a CCTrCH with the following TFCS (transport format combination set).

For a given TTI, TFC (Transport format combination) is chosen and used.

Transport format combination set is the set of all transport format combination.
This is equivalent to transport format set for transport format when several transport channels are multiplexed.
