Abstract

PURPOSE:To economize a communication equipment and to improve the reception line quality by allowing a 2nd communication equipment to apply conversion processing in packet unit to a multiple transmission channel in the same carrier frequency set by a 1st communication equipment. CONSTITUTION:The 1st communication equipments A, B utilize a voice 32kb/s line and the 1st communication equipment D utilizes a 64kb/s data line to communicate the 1st communication equipment C using a 128kb/s line. The 1st communication equipment C multiplexes three packets as packet to A [C A] (32kb/s), packet to B [C B] (32kb/s), packet for D [C D] (64kb/s) in the carrier frequency F(c1) and sends the multiplex transmission channel in 128kb/s to the 2nd communication equipment. The 2nd communication equipment extracts the packets A, B [C A] (32kb/s) and [C B] (32kb/s) from the multiplex transmission channel C to apply 4 times of time expansion, converts it into carrier frequencies F(a2), F(b2) in the unit of packets and sends the result to the A, B.
