Abstract:
A facsimile apparatus for use in transmitting audio signals from one communication terminal equipment via a communication network to another communication terminal equipment using a facsimile transmission protocol of ITU-T.T4 and ITU-T.T30, comprising:an image scanner;a printer operatively connected to said scanner;a facsimile coding/decoding device operatively connected to said scanner and to said printer;a memory operatively connected to said scanner, said printer and said facsimile coding/decoding device;a modem operatively connected between said facsimile coding/decoding device;an arrangement for processing input/output audio signals;a speech signal coding/decoding device for respectively compressing and decompressing said input/output speech signals, said speech signals coding/decoding device operatively connected to said arrangement and to said memory;communication controller for controlling at least said arrangement, said speech signal coding/decoding device; said facsimile coding/decoding device and said modem;wherein a digital input audio signal is compressed in the sending communication terminal equipment; where the compressed audio signal is divided into data frames according to ITU-T.T4 Annex A and ITU-T.T30 Annex A; wherein every data frame is identified as an audio information data frame; wherein the audio information data frames are transmitted from the sending communication terminal equipment to the receiving communication terminal equipment using the facsimile transmission protocol and are stored in the receiving communication terminal, a transmission duration of the compressed audio signals being shorter than a duration of the digital input audio signal dependent on a data frame transmission rate between the sending and receiving communication terminal equipment; andwherein the stored audio information data frames are output as digital audio signal after application of a decompression method or are further-processed.
