BECN & FECN

Experts,
I have read a number of books on these two topics and I'm yet to find
a uniform explanation. Below are my explanations correct me if I'm
wrong,

BECN- FR switch sets this bit in a frame header as the destination
replies to the sender - to inform the sender of congestion.

FECN - This bit is set when traffic is unidirectional (eg video
stream), but only this is addressed to destination to generate a
pseudo packet so that FR switch can set the BECN back to the sender.

Am I correct?

Thanks in advance.
