I think it is really depending on what kind of provisioning system you have. Circuit ID is determined by your provisioning system for CLR/DLR reference. As long as you can find circuit info quickly, it doesn't matter that much. Alex Jay Hennigan wrote:
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?
