Abstract
A method and system provides connections to an ATM system and includes selective echo cancellation. The system includes two interworking units, an echo canceller, and a signaling processor. The signaling processor receives and processes signaling to provide connection control instructions to the interworking units. The first interworking unit will accept a connection, and if the connection does not require echo cancellation, interwork the incoming connection with an ATM connection to the ATM system. If the incoming connection requires echo cancellation, the first interworking unit will interwork the incoming connection with an ATM connection to the second interworking unit. The second interworking unit will interwork the ATM connection with another connection to echo cancellation. After echo cancellation, the second interworking unit will interwork the connection from echo cancellation with another ATM connection to the ATM system.
