In my opinion the circuit ID should be an abitrary (but unique) value
and nothing more. As Nick suggested start at 1 and go up. If your
company is called ABC Ltd then maybe have your first circuit ID as
ABC00000001 and count up from there, it's as simple as that.

For me, all the circuit ID should be is a record number/ID of a
database entry and nothing more (or a search string). Some people like
to have circuit IDs which include circuit types, or circuit speeds, or
interface type, but as you asked, do you then change the circuit ID if
the circuit speed changes, or the interface types changes, or the
medium etc?

No, it's just a pointer to a database record, KISS.
