Abstract

"TRANSPORTE DE PROTOCOLO DE INTRANET DE SERVIçOS DE TELEFONIA PSTN PARA PSTN". Um sistema para transportar sinalização terminada em rede comutada pública (PSTN) (25a e 25b) através de uma rede de protocolo de Internet (IP) (13) inclui uma porta de acesso (29a) entre a PSTN (25a e 25b) e a rede IP. A porta de acesso recebe uma mensagem de sinalização de telefonia a partir da PSTN e determina se a mensagem de sinalização de telefonia mapeia para uma mensagem de sinalização IP. Se a mensagem de sinalização de telefonia não mapeia para uma mensagem de sinalização IP, a porta de acesso empacota a mensagem de sinalização de telefonia em uma mensagem de sinalização IP especial para transporte pela rede IP. Se a porta de acesso recebe uma mensagem especial de sinalização IP especial, a porta de acesso desempacota a mensagem de sinalização de telefonia a partir da mensagem especial para transporte pela PSTN (25a e 26a). Se a porta de acesso (29a) recebe sinais DTMF da PSTN (25a e 25b), a porta de acesso traduz os sinais DTMF em dígitos e empacota os dígitos em uma mensagem de sinalização IP especial para transporte pela rede de IP (13). A porta de acesso (29a) também empacota os sinais DTMF em uma mensagem de protocolo de transporte de meio de IP para transporte pela rede de IP (13).
