Instead, a transparent NAT is used. Network An array of points interconnected by communications channels. Network Management Fun

8、ction to check the Layer 1-3 connectivity of any device in the home. NID Network Interface Device. Regulatory term of key importance to telephone companies. There is a physical point and a device where the telephone network terminates and the customer premises network begins. Sometimes this is simpl

9、y a passive device, and sometimes this is a powered device. For a typical FTTP network, the ONT is at the NID. For a typical early stage FTTN network, the NID is simply a passive device at the side of the house and the VDSL signal actually continues into the house. ONT Optical Network Termination. T
