Abstract (en)

[origin: WO9638943A1] A demultiplexer which in a demultiplexing process selects an output for a signal received on input, a protection switch unit which includes one such demultiplexer and a telecommunications network which includes one such protection switch unit, wherein the demultiplexer has an input (IN+, IN-) and at least two outputs (OUT1+, OUT1-, OUT2+, OUT2-). A first connection point (IN1+) in the input is connected to a first transmission line (TLINE_1) for conducting an input signal thereto. A first connection point (OUT1+, OUT2+) in each output is connected to the transmission line (TLINE_1) via a respective first controllable signal forwarding device (Q1, Q2). An externally controllable signal switch means (S1, S2) is also connected to each output. A switch means (S1) controls one of said first signal forward devices (Q1) to forward the signal that is applied over the first transmission line (TLINE_1) to the first connection point (OUT1+) in a selected output.
