In a method of transmitting data in a ring-shaped teletransmission network (1; 11), such as e.g. an MS SPRing, a plurality of primary channels (W1, W2, W3, W4) and secondary channels (P1, P2, P3, P4), respectively, may be transferred on the transmission lines between the network elements, so that a secondary channel is provided for each primary channel. Connections may be set up in the network which in each transmission line uses one of the primary channels thereof, it being possible for a connection to use different channels in each transmission line. In case of drop-out of the transmission line or a network element, respectively, an auxiliary connection may be established via the secondary channels in the remaining transmission lines. In a first one (K2) of the two closest network elements, the secondary channel (P1) associated with each auxiliary connection is connected to the corresponding primary channel (W1), and in the second one (K4; K5) the secondary channel (P1) associated with the auxiliary connection is connected to the primary channel (W2) which, before the rupture, was connected via the connection now interrupted to that of the primary channels (W1) in the first network element (K2) which corresponds to the secondary channel (P1). |
