ABSTRACT:
A line protection device for signal and control lines accessing a telecommunications, data communications and/or distributed computer system comprises a modular unit which includes input and output sockets and one or more two-stage protection circuits housed within an electromagnetically shielded enclosure in the form of a metal box. Each two-stage protection circuit comprises a transient/surge part and a suppression part. The modular units are adapted to be fitted into signal lines leading to equipment cabinets or vaults at positions externally of such equipment cabinets or vaults so as to remove unwanted pulses in the signal lines upstream of the cabinets and to shield the signal lines against further introduction of unwanted pulses prior to entry of the signal lines into the cabinets.
