sonetLineDayCVs

The line code violation (CV-L) count is the number of BIP-8
errors which were detected at the SONET line layer
interface in a previous 1-day interval.  Each line BIP-8
can detect up to eight errors per STS-1 frame, with each error
incrementing the CV counter.  CVs for the line layer are
collected using the BIP-8s in the B2 byte located in the
line overhead of STS-1.  (Since all CVs on an STS-N line are
counted together, this is equivalent to counting each error in
the BIP-8N contained in the B2 bytes of the STS-N line
overhead.)  Thus, on an STS-N signal, up to 8 x N CVs may
occure in each STS-N frame.
