Abstract

PURPOSE:To accommodate terminal equipments installed decentralizingly at remote location to a common line control exchange by adding a signal processing device converting a terminal control interface to a common line interface. CONSTITUTION:A data line 3 of a terminal equipment 2 and a terminal control signal line 4 are connected to a relay line 9 by a multiplexer 8 to apply long range transmission with a multiplexer 8' of the exchange side and the signal of the signal lines is converted into a signal for the common line interface from the terminal control interface by a signal processing unit 11 and connected to the common line signal device 12 of the exchange 1 and the data line 13 is accommodated directly to the channel of the exchange 1. Thus, terminal equipments installed decentralizingly to a remote location are accommodated to the exchange without using lots of installation investment newly.
