Cyclic redundancy checks to improve link initialization processing and to exchange system error information are described. A cyclic redundancy check (CRC) checker including a unique pattern detector (710), a CRC generator (720), a CRC initializer (730) and a CRC verifier (740) is described. The CRC checker prepopulates the CRC generator for a unique pattern. Upon receipt (850) of the unique pattern within a data stream received over a digital transmission link such as an MDDI link, the CRC checker checks CRCs (860) without queueing and storing data. The CRC generator system can also intentionally corrupt CRC values to transmit system error information, the CRC generator system including a CRC generator (910), a CRC corrupter (920), and error detector (930) and an error value generator (940).
