1. A method of reporting severely errored seconds (SES) in a consistent manner across a plurality of connections in a service provider network comprising:

  • computing a local CRC octet based on a received bit stream;

    comparing, by a processor, the local CRC octet to a received CRC octet;

    identifying a CRC anomaly when the local CRC octet is not identical to the received CRC octet; and

    normalizing a CRC anomaly counter based on a value for a CRC computation period (PERp), wherein a Severely Errored Second is declared if there are more than N CRC anomalies in a second.
