Circuit numbering scheme - best practice?

We've grown to the point that "The MCI T-1 in Ontario" or "Bob's 
ethernet to port 6/23 on switch 7" aren't scaling.  Also in working with 
carriers we are frequently asked to provide our internal circuit number.

I've seen a lot of the the LEC scheme NN-XXXX-NNNNNN where XXXX has some 
significance with regard to the speed and type of circuit.  The leading 
NN seems to be a mystery and the trailing NNNNNN is a serial number.

I've also seen DS1-NNNNNNN as a straight speed-serial number type of 
thing and horrendously long circuit numbers including CLLI codes such as 
101/T3/SNLOCAGTH07/SNLOCA01K15 .

Any suggestions from those who have been down this road as to a schema 
that makes sense and is scalable?  Are there documented best practices?
