What is ccasBwdRSSubscriberLineBusy?

This object specifies the backward signal indicating that the line or lines connecting the called subscriber to the exchange are busy or otherwise engaged. This is the R2 signal that ultimately produces the busy tone or busy-call-disposition a caller experiences, so a gateway that fails to recognize this signal correctly might instead let a call ring indefinitely against a genuinely busy line. When a called subscriber is already on another call, the terminating exchange sends this backward signal, which the originating gateway translates into a busy indication back to the calling party.
