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 increment a CRC anomaly counter by a value of M, wherein the value M is equal to PERp/K, where PERp is a CRC computation period and K is a positive integer.
2. The apparatus of claim 1 , wherein K is equal to 20 or 15.
3. The apparatus of claim 1 , wherein a Severely Errored Second (SES) is declared if there are more than 18 CRC anomalies in a period of one second.
4. The apparatus of claim 1 , wherein the apparatus is a linecard that is capable of supporting ADSL2 and VDSL2.
5. The apparatus of claim 1 , wherein the apparatus is a customer premises equipment that is capable of supporting ADSL2 and VDSL2.
6. The apparatus of claim 1 , wherein the transceiver includes at least one digital signal processor.
7. The apparatus of claim 1 , wherein the transceiver includes at least one ASIC.
8. A method comprising:
incrementing, in a transceiver, a CRC anomaly counter by a value of M, wherein the value M is equal to PERp/K, where PERp is a CRC computation period and K is a positive integer.
9. The method of claim 8 , wherein K is equal to 20 or 15.
10. The method of claim 8 , wherein a Severely Errored Second (SES) is declared if there are more than 18 CRC anomalies in a period of one second.
11. The method of claim 8 , wherein the method is performed in a linecard that is capable of supporting ADSL2 and VDSL2.
12. The method of claim 8 , wherein the method is performed in a customer premises equipment that is capable of supporting ADSL2 and VDSL2.
