Hi Ti Folks,
I went through AIF2 UG, wiki and cpri specification. I have doubts on control word arrangement onto a hyperframe.
Lets say i have CW words [continous data from cw0 to cw15]
cw0,cw1,cw2,cw3,cw4,cw5,cw6,cw7,cw8,cw9,cw10,cw11,cw12,cw13,cw14,cw15.
1. Are the control words[according to CPRI Specification V4.2 (2010-09-29) page 45 --> Figure 15] put into following byte positions
[16,17,18,19,80,81,82,83,144,145,146,147,208,209,210,211]. In other words,
cw0 is into 16th position, cw1 is into 17th position, cw2 is into 18th position, cw3 is into 19th position..so..on...
or
2. Are the control words[according to CPRI Specification V4.2 (2010-09-29) page 45 --> Figure 15] put into following byte positions
[16,80,144,208,17,81,145,209,18,82,146,210,19,83,147,211]. In other words,
cw0 is into 16th position, cw1 is into 80th position, cw2 is into 144th position, cw3 is into 208th position..so..on...

I do understand that AIF2 doesn't support cpri specification v4.2, at the sametime i think the question i put is independent of the cpri specification version.
Thanks
