Answer: Faulty Transmission

This weeks issue was identified with on of the simplest RA controls to put in place. It was identified with a CDR sequence number checker. The majority of switches tag each CDR with a unique sequence number(a 6 or 8 digit number). By simply ccomparing the difference between the first and last sequence numbers to the total CDRs within a file, along with the last sequence number in file A to the first sequence number in file B, you have a fool proof way of identifying whether you are receiving all data at the collector.
