Abstract
A (DS3) network interface unit (NIU) by-pass architecture places the NIU on its own circuit card and exclusive of by-pass switching (and relay) components, which are installed in the equipment shelf, proper, so that physical removal of the NIU card will leave the by-pass circuitry intact. The by-pass circuit responds to an abnormality of the NIU card, such as malfunction or physical removal of the NIU from its card slot, and also to a power supply failure. It also contains an indicator to draw attention to a failed NIU, increasing the likelihood that someone will notice a damaged card.
