摘要
In a radiotelephone network, processing steps previously applied to digital voice transmissions received by a regional radio transmitter/receiver but not applied to analog voice transmissions received by the transmitter/receiver are applied to such analog voice transmissions at the transmitter/receiver itself such that analog voice transmissions and digital voice transmissions may be transmitted identically between the regional radio transmitter/receiver and a regional switching center. In particular, a digital speech encoder/compressor and a corresponding digital speech decoder/decompressor (together referred to as a codec) provided at remote transmitter/receivers and the regional switching center are also provided at the regional radio transmitter/receiver so as to apply the same processing to analog voice transmissions received from the remote transmitter/receivers as is applied to digital voice transmissions at the remote transmitter/receivers.
