I did some digging and also enlisted Stephen Botzko to dig around a bit, 
too.  There are many references to cascaded MCUs, with the earlier 
document Steve was able to find being H.140 from 1988.  Figure 1 shows a 
cascaded MCU, but is not called that.  There are also references in 
F.702, H.323, and a few other ITU documents.  It's also mentioned in RFC 
4575, but also not explicitly defined.

Perhaps we just leave it alone.  "Cascade" is defined in the dictionary 
as "Arrange (a number of devices or objects) in a series or sequence".  
And, that's what we're describing.  So perhaps rather than go with 
looking for a technical definition, we just leave it up to Websters?
