Abstract

"APERFEIçOAMENTO INTRODUZIDO EM TELEFONE SEMI-PúBLICO". No qual um primeiro e um segundo canais telefónicos independentes são digitalmente multiplexados e transmitidos por uma linha (12) constituída por um único par de fios, a dita linha terminando num conjunto de meios demultiplexadores que encaminham os ditos canais telefónicos a um primeiro e um segundo telefones públicos acondicionados num gabinete único. Os conjuntos de elementos externos de cada telefone - compreendendo monofone, teclado, visor e entrada do elemento de crédito - podem ser instalados lado a lado na mesma face do gabinete, ou em faces opostas do gabinete, sendo a privacidade dos usuários assegurada mediante anteparos verticais separando as porções do gabinete em que estão instalados os ditos primeiro e segundo telefones.
