Abstract (en)
[origin: WO0013361A1] The invention relates to a ring network subdivided into a first and a second part, wherein working signals are fed to the first and the second part of the ring network from a central network element. Protection signals are transmitted in the direction of the working signals to the network elements of the other part of the ring as far as the network elements that close the parts of the ring. The protection signals are then transmitted in the direction opposite the working signals in the corresponding part of the ring in the direction of the central network element. -
