Abstract

"DISPOSITIVO DE PORTA VOIP E MéTODO DE CâMBIO EM SéRIE DE LIGAçãO úNICA DIGITAL". Um dispositivo de porta VoIP (Voz através de rede IP) inclui uma seção d inserção de padrão de identificação, seção de detecção de padrão de identificação, seção de montagem de quadro de passagem, e seção de processamento de quadro de passagem. A seção de inserção de padrão de identificação insere um padrão de identificação de um padrão de bit predeterminado em um sinal de recepção a partir de um tronco de trânsito IP, e envia o sinal para um câmbio digital. A seção de detecção de padrão de identificação detecta um padrão de identificação de um sinal de recepção a partir do câmbio digital. A seção de montagem de quadro de passagem converte um pacote RTP (Protocolo de transporte em tempo real) obtido do tronco de trânsito IP em um sinal de voz digital em um formato de quadro de passagem tendo uma taxa de bits de 64 kbps quando a seção de detecção de padrão de identificação detecta um padrão de identificação. A seção de processamento de quadro de passagem converte um sinal de voz digital no formato de quadro de passagem recebido do câmbio digital em um pacote RTP quando a seção de detecção de padrão de identificação não detecta padrão de identificação. Um método de câmbio em série de ligação única digital também é divulgado.
