Bill,
	There is such a document that was written by BBN Communications
for DCA last year.  It is called "C/30E Physical Layer Interface Guide."
I believe that DCA was going to add a few things and publish this in
some easily obtainable mode.  (The cover of the document includes,
"DCAI No: DCAI-350-180-()."  I'm not sure whether or not this will help
uniquely identify the document to DCA.)
	I would check with DCEC (start with Charlie Morgan,
"CEMorgan@DDN1.arpa") to find out the status of this document.  He
might also know how to obtain a copy of it.
