Recrifier

For power rectification from very low to very high current, semiconductor diodes of various types (junction diodes, Schottky diodes, etc.) are widely used. Other devices which have control electrodes as well as acting as unidirectional current valves are used where more than simple rectification is required, e.g., where variable output voltage is needed

Network Terminal

device that connects the customer's data or telephone equipment to a carrier's line that comes into a building or an office. The NT device provides a connection for terminal equipment (TE) and terminal adapter (TA) equipment to the local loop. The network termination used in the specific case of an ISDN Basic Rate Interface is called an NT1
