A broadcaster broadcasts all network cells received via a receive channel of a telecommunication line serving the installation to digital loops including terminals. A hybrid of dielectric defined and non-dielectric defined electrical interconnects reduces the potential for electrical interconnection failure without having to control the dielectric defined interconnect ratio of substrates. The CDMA receiver includes a reception unit for obtaining one received signal from the transmission signals from the plurality of transmission antennas of the CDMA transmitter in consideration of reception quality, and a unit for transmitting antenna control signals corresponding to reception power values of the received pilot signals to the CDMA transmitter.
