摘要： A communications system is provided which supports asynchronous transfer mode (ATM) communications. An ATM multiplexer is located at a customer's premises and connected to customer premises voice and data equipment. A central office ATM multiplexer is connected to various different networks in the existing network infrastructure. The central office ATM multiplexer is preferably connected to networks such as a low-speed packet-switched network, a public circuit-switched network, a private line network, and a high-speed packet-switched network. The ATM multiplexer located at the customer premises preferably supports dynamic bandwidth allocation. Additional features provided by the communications system include the ability to provide different voice encoding schemes for different users based on calling party or called party information.
