Abstract
A method for identifying faulty modules within telecommunication devices, such as ATM switches, involves generating and attaching verification codes, such as a CRC or checksum codes, to data packets at an upstream location determining the integrity of the verification codes at each of multiple downstream location within a telecommunication device; and signaling an error condition where a corrupted data packet has been detected. A verification code may be written to a field of a data packet which is not used while the packet is in transit through the telecommunication device.
