摘要 |
A voice gateway ( 64 ) includes an input port ( 70 ) that receives a voice signal from an unbundled analog line ( 62 ) coupled to a Class 5 switch ( 52 ). The voice signal is converted to a digital format by an analog-to-digital and digital-to-analog converting unit ( 76 ). The voice signal is placed into a compressed format by a compressing/decompressing unit ( 80 ) using a selected one of a plurality of compression ratios. The voice signal is placed into a transport frame by a packetizing/depacketizing unit ( 84 ) according to a selected packet format. The voice signal is multiplexed with other voice signals by an output port ( 88 ). The output port ( 88 ) places the voice signal onto a selected one of a plurality of output lines in order to transport the voice signal in its transport frame to one of an office customer premises ( 12 ) and a residence customer premises ( 14 ).
