Please pardon my ignorance.  I don't work in the telecom industry and
I don't know many of the technical details.

Several contributors to c.d.t. have discussed the method of
transmission of data calls vs voice calls over the network.  They have
pointed out the higher bandwidth utilized by data calls and the
problems of multiplexing such calls.

I would like to better understand the nature of this multiplexing.
Suppose that we have enough simultaneous voice calls to saturate the
capacity of some portion of the network.  As the other writers have
mentioned, these voice calls are assumed to have a duty cycle of less
than 100% - let's say 50%.

What happens if all those callers simultaneously break into song or in
some other way push their duty cycles up to 100%?  Do they start
losing parts of their conversations?  Or do pieces merely get delayed?
Or does something else happen?
