Question:
Is there anything wrong in the below pic?
I think picture is ok.
You may think that option 3x is not well repesented, but keep in mind that eNodeB also has a S1-U with EPC.
My concern was about option 3a, where there is no X2 shown.
That is limitation of option 3a.
Interview question as well.
But there is X2-C in 3a.
No X2-U.
Yes that’s why option 3x chosen.
With option 3a no option to transmit data through LTE leg.
Right, so in the figure I expected a dotted x2-C for option 3a…
