摘要: A communication apparatus connected to a PBX and an ATM network is provided with DTMF signal detecting portion for whether or not contained in voice from the PBX, monitoring portion, cell generating coding sending out signal, decomposing decoding coded on basis of information content decoded this transmission side codes specified form transmits reception decodes and, information, restores portion. By doing so, even case transmitting by way performing code compression, it made possible (PBX) judge/recognize without error.
