ACA: Automatic Circuit Assurance
Automatic Circuit Assurance (ACA) is a PBX feature that helps one to identify bad trunks. The PBX keeps records of calls of very short and very long duration. If these calls exceed a certain parameter, the attendant is notified. The logic is that a lot of very short calls or one very long call may snidest that a trunk is hung, broken or out of order, The attendant can then physically dial into that trunk and check it.
