Connect the NV-450M(Master) and the NV-450S(Slave) to the Line

The objective for LAN extender is to pass high speed data over a twisted pair cable. In the setup, connect NV-450M(Master) to NV-450S (Slave) through phone wire(24~26 AWG) or line simulator or any other hardware representation of a cable network, with or without noise injection and crosstalk simulations.
