ABSTRACT:
Methods and apparatus are disclosed for end-to-end ATM calls based on the interworking of ATM SVC signaling (such as private network-network interface signaling) with A.2630.1 AAL2 signaling. In one network, Q.2630.1 AAL2 signaling in the originating access segment triggers, on proper authentication, ATM SVC signaling (e.g., PNNI, IISP, AINI, etc.) in the core, which triggers Q.2630.1 AAL2 signaling in the terminating access segment. The triggering is done at the edge-core boundary where an AAL2 switch and/or multiplexer or an ATM switch with AAL2 multiplexing/switching capabilities is located. In the access network between the ATM-AAL2 edge switch and the edge gateway, multiplexed AAL2 virtual channel connections (VCCs) are typically used. Single-CID AAL2 SVCs are typically used in the core network, and between the ATM-AAL2 edge switch and PSTN trunk gateways. The binding of voice calls to ATM bearer channels is done at the edge gateway when triggered by a call agent.
