Abstract

There is provided a multiplexer which in a multiplexing process selects an output signal from a plurality of input signals, a protection switch unit which includes one such demultiplexer and a telecommunications network which includes one such protection switch unit, the multiplexer has an output (OUT+, OUT-) and at least two inputs (IN1+, IN1-, IN2+, IN2-) where two input signals corresponding to the inputs are received. A first connection point (IN1+, IN2+) in each input is connected to a first transmission line (TLINE_1) via a respective first controllable signal forwarding device (Q1, Q2). An externally controllable switch means (S2, S1) is also connected to each output for forwarding a signal or at least a part thereof delivered to said input to a first transmission line (TLINE_1). The first transmission line (TLINE_1) is connected to a first connection point (OUT+) in the output, where a signal of good quality is obtained.
