Circuit id
From Wikipedia, the free encyclopedia
A circuit id is a company specific identifier assigned to a data or voice network between two locations. This circuit is then leased to a customer by that id. If and when a subscriber has an issue with a circuit, the subscriber contacts the telecommunications provider to provide this circuit id for action on the designated circuit.
