Abstract
Transient voltage surge protection circuitry for a plurality of transmission line-pairs (10-18) utilizes a single multi-terminal protective network (34) coupled to individual lines (52-56) of the transmission line-pairs by full-wave diode bridge circuits (48) and resettable fuse elements (62,64).
Claims8
A circuit arrangement comprising;
- a plurality of telecommunications line-pairs connected to first and second terminals of a protective network,
- first lines of said plurality of line-pairs connected to a first common terminal through a means for isolating respective first lines, said first common terminal connected to the first terminal of the protective network through a first fuse element.
