US 2002/0118673 A1 · Method for eliminating multiple modulation and demodulation of voice band data communication over packet and low data rate digital networks

Abstract

A method of processing Voice band Data in a communication path in a telecommunication network. The communication path consists of a plurality of Voice band Data relay gateways, including a first Voice band Data relay gateway, a last Voice band Data relay gateway, and at least one Voice band Data relay gateway between the first and last Voice band Data relay gateways. The method includes steps of detecting the Voice band Data relay gateway, and disabling the at least one Voice band Data relay gateway between the first and last Voice band Data relay gateways, whereby the at least one Voice band Data relay gateway between the first and last Voice band Data relay gateways does not encode and decode the Voice band Data.
