Transfer network for transferring multiple information streams and danger reporting facility

摘要

The transmission network has two information flows, a circuitry unit that is provided in a frequency band (FB1) with a lower threshold frequency (f-u) of 1kilo hertz for coupling signals in a transmission channel. A switching unit has appropriate filter characteristic, a transmission channel takes place with an arbitrary type information transfer and another transmission channel takes place an information transfer with unit of the digital transmission technique.
