Abstract

Techniques for communicating include transporting circuit-switched narrowband traffic over a packet network (101) and delivering the narrowband traffic from the packet network to a circuit-switched network (102B). The circuit-switched narrowband traffic can be transported dynamically over the packet network (101), and multiple circuit-switched narrowband calls can be multiplexed over a single connection in the packet network. A system incorporating such techniques can support voice or other narrowband calls over a packet backbone network, while interfacing seamlessly with an existing SS7-based public telephone network (126) that uses circuit-switched technology.
