Abstract

"TERMINAL DE SISTEMA PARA UM LAçO LOCAL SEM FIO". Um terminal de sistema para um laço local sem fio é conectado a uma pluralidade de telefones e conectado a uma estação base para o laço por um canal de rádio. Um circuito para detecção de circuito detecta um telefone dentre os telefones que estão fora-do-gancho, e interrompe uma CPU (unidade processadora central). Um seletor de dois fios conecta o telefone fora-do-ganho a uma interface. O terminal de sistema, por conseguinte, permite que uma pluralidade de telefones sejam seletivamente usados com uma interface única isto é, sem recorrer a uma pluralidade de LSIs (circuito integrado de grande escala) de conversão de dois fios.
