发明名称 Communication line protection
摘要 <p>The circuit (3) has two branches between conductors of a ground or telecommunication line to which an equipment (2) to be protected is connected, where the circuit connects two terminals (A`, B`) by capacitors (C1, C2). The branches respectively comprise diodes (D1, D2), the capacitors and zener diodes (31, 32) in series, where resistances (R1, R2) are respectively connected in parallel over the capacitors. A third resistance (R3) maintains a voltage between two terminals (A, A`). Independent claims are also included for the following: (1) a device for protecting an electronic equipment (2) a method for protecting an electronic equipment.</p>
