CRC counter normalization
View Patent ↗The ability to accurately and efficiently calculate and report communication errors is becoming more important than ever in today's communications environment. More specifically calculating and reporting CRC anomalies in a consistent manner across a plurality of communications connections in a network is crucial to accurate error reporting. Through a normalization technique applied to a CRC computation period (e.g., the PERp value), accurate error identification and reporting for each individual connection can be achieved.
1. An apparatus comprising:
a transceiver operable to:
normalize a CRC anomaly counter based on a value for a CRC computation period (PERp) when the value of the PERp is less than 15 ms;
