Title: Some basic question from iDirect HUB teleport.
Post by sohel2020 on Apr 23^rd, 2014 at 8:53am

i am a new hub Station Engineer. we are using iDx 3.1. I have
some question.

1. what is frame length? (we see from iBuilder that Frame length is 125ms. What does it means?)
2. How does iDirect calculate its time slots?
3. iDirect 3.1 introduce 2D-16 State FEC type instead of TPC. When we create B/W profile we see some FEC Type.

(like, 2D16S-170byte 3/4, 2D16S-100byte 3/4) what is the significant of 170 byte and 100 byte.

Thanks is Advance.
