Abstract
A system terminal for a wireless local loop is connected to a plurality of telephones and connected to a base station for the loop by a radio channel. An open circuit detection circuit detects one of the telephones which is off-hooked, and interrupts a CPU (Central Processing Unit). A two-wire selector connects the off-hooked telephone to an interface. The system terminal therefore allows a plurality of telephones to be selectively used with a single interface, i.e., without resorting to a plurality of two-wire conversion LSIs (Large Scale Integrated circuits).
