Abstract
A voice adaptation device (18) provides an interface between a narrowband local access network and a broadband asynchronous transfer mode (ATM) backbone network (16). The voice adaptation device (18) includes a T1/E1 network adaptor (50) that converts T1/E1 signals carrying narrowband voice traffic into an ATM cell format. The T1/E1 network adaptor (50) also performs echo cancelling, voice enhancement, digital voice protocol conversion, and compression/decompression on the narrowband voice traffic. The voice adaptation device (18) also includes a synchronous optical network formatter (52) that places ATM cells generated by the T1/E1 network adaptor (50) into synchronous optical network signals. The synchronous optical network signals are transmitted across the broadband ATM backbone network (16).
