Yes indeed.I'm curious too as to what happened to the ring final circuit? Hopefully it wasn't needed for anything!
On the RFC, you are allowed a spur at the origin, and thus keep the ring.
You said the customer "only wanted a twin socket changed" yet you ripped out a RFC from the CU? I think that's what he is trying to say.
