Abstract

1. A system for electrically transmitting information with a high level of security, in particular a radio relay system, wherein a plurality of transmission channels are provided, and monitoring- and switch-over devices which, in the event of disturbances in a transmission channel, initiate a stand-by connection, characterised by a stand-by transmitter (hot stand-by) (Sh ) which is in the operating state, is connected to a control device (StE) and which can be connected via a routing line (RL), without the interposition of a channel separating filter, to the input of a transmitting channel separating filter which includes the routing lines for the connection of the individual transmission channels, further characterised by short-circuiting or interrupting elements (X) which are arranged in the individual transmission channels, can be controlled by the control device (StE) and which disconnect the disturbed transmitter (S) when the stand-by transmitter is connected and additionally prevent the absorption of the same-frequency hot stand-by signal in this channel separating filter (KF), and further characterised by the connection and disconnection, without the use of a channel separating filter, of a hot stand-by receiver (Eh ) which is arranged at the receiving end.
