Could you point to the documentation?

I having trouble with language that sounds like one concept and I  
suspect is in fact another. Take as one example the basic digital  
signaling hierarchy. The specifications call for a certain rate plus  
or minus some number of parts per million. If they are within  
tolerance, the amount that they would speed up or slow down is  
measured in a pretty small number of bits per second. So I don't think  
the speed of the links is materially changing. If on the other hand we  
are discussing the volume of traffic using that available capacity, it  
is absolutely clear that there are diurnal, weekly, and seasonal  
variations as well as growth in time.

Are we talking about bit rate, which one might expect to be modified  
by environmental characteristics and is in fact very tightly  
controlled to prevent that, or traffic volume?
