Abstract

An access platform pools a plurality of different signal processing resources, herein represented by different types of speech-coding algorithms. The access platform is coupled to the Internet, a local-exchange-carrier (LEC), and other communications facilities such as, but not limited to, a plurality of long-distance facilities provided by any one of a number of long distance carriers, e.g., AT&T. For each call through the access platform, one of the plurality of signal processing resources is allocated as a function of signal type either through signal detection or out-of-band signaling. For example, the access platform first determines if the call is an audio call or a non-audio (or data) call by detecting the type of signal. If the call is an audio call, the access platform switches in echo canceling resources. On the other hand, if the call is a data call, the access platform determines if a speech-coding algorithm is being used and, if necessary, switches in a compatible speech-coding resource.
