Operation
SOP’ Communication is recognized by electronics in
one Cable Plug (which may be attached to either the
UFP or DFP). SOP Communication between the Port
Partners is not recognized by the Cable Plug. the term
Cable Plug in the SOP’ Communication case is used to
represent a logical entity (RT1710S) in the cable which
is capable of PD Communication.
Both SOP Communication and SOP’ Communication
take place over a single wire (CC pin). For a product
which does not recognize SOP’ Packets, this will look
like a non-idle channel.
