Patent ID: 7961713

Claim:
A method for exchanging signaling information between a PRA ISDN connection and a packet-oriented exchange via a peripheral adapter, comprising: processing by the packet-oriented exchange signaling information transferred from the PRA ISDN connection signaling information of a BRA ISDN connection out of a plurality of BRA ISDN connections; adapting in the peripheral adapter the signaling information transferred from the PRA ISDN connection in accordance with the ISDN connection type of the BRA ISDN connection; and adapting signaling information transferred from the packet-oriented exchange to the peripheral adapter in accordance with the ISDN connection type of the PRA ISDN connection, wherein the PRA ISDN connection is represented by said plurality of BRA ISDN connections in the packet-oriented exchange, and wherein call identifiers of said plurality of BRA ISDN connections are adapted in said peripheral adapter with respect to uniqueness within the D-channel of said PRA ISDN connection and wherein call identifiers transmitting via the D-channel of said PRA ISDN connection in the direction of said packet-oriented exchange are allocated to the D-channels of said plurality of BRA ISDN connections without adaption.
