초록 ▼

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. A method in transceiver, the method comprising: determining a first value for a CRC computation period based on a first communication parameter value;calculating a first number of normalized CRC anomalies based on the first value for the CRC computation period;declaring a severely errored second when the first number of normalized CRC anomalies in a one second interval is 18 or greater than 18. 2. The method of claim 1, further comprising: determining a second value for the CRC computation period based on a second communication parameter value, different than the first communication parameter value, wherein the first value for the CRC computation period is different that the second value for the CRC computation period;calculating a second number of normalized CRC anomalies based on the second value for the CRC computation period; anddeclaring a severely errored second when the second number of normalized CRC anomalies in a one second interval is 18 or greater than 18. 3. The method of claim 2, wherein calculating the second number of normalized CRC comprises incrementing a CRC anomaly counter by a value of M wherein the value M is equal to PERp/K, where K is a positive integer and PERp is the value of the second CRC computation period. 4.
