ABSTRACT:
The invention concerns a method of controlling an access network (AN) with a number of user ports by means of an exchange (LE) connected to the access network (AN) via an interface, as well as such an exchange (LE) and such an access network (AN). The exchange (LE) and the access network (AN) exchange user data via a number of bearer channels, and messages associated with different protocols (PSTNP, LCP, CP, BCCP) via at least one control channel. Each of the protocols (PSTNP, LCP, CP, BCCP) is formed by a set of messages for performing a specific task, and the association of a message to one of the protocols (PSTNP, LCP, CP, BCCP) is entered in the message as part thereof. The exchange (LE) and the access network (AN) exchange messages according to one of the protocols (BCCP) via one of the control channels, which serves to dynamically allocate bearer channels to user ports, and wherein by means of said messages the switching of connections between user ports and the exchange (LE) via a particular bearer channel is controlled by the exchange (LE). Further messages (M7 to M15) are used in the protocol (BCCP) for the dynamic allocation of bearer channels to establish and release interconnections in the access network (AN). The establishment and the release of such interconnections is controlled by the exchange (LE) with the protocol (BCCP) extended in this manner.
