A CDE Definition
(Network Interface Unit) See network interface device.
network interface device
Equipment from the telephone company that terminates its lines at the customer's premises. The network interface device (NID) provides the demarcation point between the telephone network and the customer's internal wiring. Residing outside the building or in a basement, residential NIDs are no more than a wiring panel that connects the lines. More elaborate NIDs for commercial customers include circuit boards that can report problems. See optical network terminal.
