Abstract

PURPOSE:To simplify the entire constitution by sending data between a terminal equipment in the inside of a building and a multiplex exchange connected to the end of a telephone line through a radio wave as a medium thereby eliminating the need for installation of a drawing line to the building and installation of connection lines to respective terminal equipments. CONSTITUTION:An exchange-side antenna 3 is provided on the upper part of a support 2 provided between buildings 1, 1 and a multiplex exchange 4 is provided on a prescribed position at the upper part of the support and connected to the end of the telephone line 5. The inside of the building 1 is provided with a stationary terminal equipment 6 or a portable terminal equipment 7 and a radio wave is transmitted and received between a terminal antenna 8 mounted on each terminal equipment and an exchange side antenna 3. Thus, the installation of a drawing line to each building is not entirely required. Moreover, connection lines connecting the drawing line to respective terminal equipments are not entirely needed actually.
