NEW YORK (Bloomberg) — Bermuda-based Tyco Electronics Ltd., a maker of electronic connectors, was accused in a lawsuit by ADC Telecommunications Inc. of infringing five patents for fibre-distribution terminals.

ADC, which makes phone equipment for AT&T Inc., claims Tyco uses its technology in CSX-3 cabinets, according to the lawsuit filed September 19 in federal court in Minneapolis. ADC seeks an order stopping Tyco's actions, plus unspecified damages.
