Abstract
The transmission of signaling information between network nodes connected to one another ensues in separate signaling channels. A signaling protocol corresponding to a broadband ISDN layer model is respectively defined for such signaling information. Among other things, an ATM adaption layer (S-AAL) is defined therein which, in addition to having a general adaption sub-layer (AAL5), also has two service-specific sub-layers (SSCOP, SSCF) available to it. One of these service-specific sub-layers (SSCF) is thereby modified, as compared to ITU Recommendation Q.2140, each that, for a call set up, a communication over the respective signaling channel occurs between two network nodes connected to one another without a previous check of the transmission link.
