Abstract  Abstract

Method for transmitting a digital broadband signal in a tributary unit concatenation via a network of a synchronous digital multiplex hierarchy. A pointer for positional identification in a frame is allocated to the first tributary unit in a tributary unit concatenation; instead of a pointer the further tributary units receive a concatenation indicator. Every cross-connect equipment along a transmission link recognizes the tributary unit concatenation and forwards the tributary units thereof in the correct sequence. When a clock matching is required in the case of a first tributary unit a pointer skip is initiated at all further tributary units. This requires hardware and software. This is eliminated when all tributary units (TU-12. sub.1 through TU-12.sub.5) containing the broadband signal (DSa) have a pointer (PTR1 through PTR5) having the value of the positional identification of the first tributary unit (TU-12. sub.1) allocated to them. The individual tributary units (TU-12.sub.1 through TU-12.sub.5) can then pass the cross-connect equipment if necessary with an individual pointer skip (PS) independently of one another. A restoration of the tributary unit concatenation occurs at the reception side after the recognition of the pointers (PTR1 through PTR5) in that leading tributary units (TU-12.sub.2 TU-12.sub.5) are delayed by delay elements (L2 L5).
