Error Detection and Framing in Packets Transmitted in a Sequence of Fixed-length Cells A digital error check sequence for detecting errors in messages. The error check sequence has a form such that it is distinguishable from a sequence of padding bits, and can thus be employed to both mark the end of the message and determine whether there was an error in the transmission of the message. In one embodiment, the error check sequence includes a single-bit first field and a cyclic redundancy code (CRC) whose least significant bit is always 1. The value of the first field is chosen such that when it is appended to the message, the result is a CRC with a least significant bit of 1. Also disclosed are methods and apparatus for generating the error check sequence and transmission and receiving systems employing the error check sequence.
