A Connection Fault Management, CFM, maintenance point and method for providing Data Driven Connection Fault Management, DDCFM, in CFM maintenance points in a communication network. A Reflection Responder (30), an RFM Receiver (40), and a Decapsulator Responder (50) are implemented in existing CFM maintenance points. The Reflection Responder (30) selects frames to be reflected, mirrors the selected frames if a Continuation option is se and encapsulates the selected frames with Return Frame Message, RFM, OpCode. The RFM Receiver (40) sends received RFM frames to an analyzer (42) if addressed to the maintenance point and otherwise to a passive multiplexer (33). The Decapsulator Responder (50) decapsulates Send Frame Message, SFM, frames and sends decapsulated frames toward the destination specified in each frame. |
