Abstract:
A telecommunications network operating according to the SONET/SDH standard, comprising:a pair of transparent multiplexers (T-Muxs) connected over a bidirectional high speed span for transparently transporting high rate traffic; anda plurality (I) of bidirectional self-healing rings, each ring (K.sub.i) having a ring rate R.sub.i, and including at least two nodes (A.sub.i, B.sub.i) connected to each other and to said transparent multiplexers over a i-th WIP line for transporting working and protection traffic in a forward direction, and a i-th P/W line for transporting protection and working traffic in a reverse direction,wherein I is four, i is the index of a respective bidirectional self-healing ring, and said high rate is the sum of all said ring rates R.sub.i and is an STS-48/STM-16.
