Re: Final draft of response to the OIF
You quoted T1.105:

i refer you to section 7.3.1 of ANSI T1.105 - 2001 (aka SONET base spec)
you will that your interpretation is not the one specified in this
" Super rates services are mapped into and transported as STS-Nc SPE
[N=3X there X = 1, 4, 16, 64 or 256]"
Somehow you left out the last part between the square brackets:
"or SDH VC-4 or VC-4-Xc, where X=N/3]"
This clearly means that an STS-3c == VC-4 == super rate of STS-1.
this is exactly what we used in RFC 3946
Always remember that you are unique...just like everyone else...
