rede digital de serviços integrados (ISDN)

Integrated Services Digital Network (ISDN)

Linha telefônica digital usada para fornecer uma largura de banda superior. Normalmente, a ISDN na América do Norte está disponível de duas formas: A interface de taxa básica (BRI) consiste em dois canais B a 64 quilobits por segundo (Kbps) e um canal D a 16 Kbps; a interface de taxa primária (PRI) consiste em 23 canais B a 64 Kbps e um canal D a 64 Kbps. Uma linha ISDN deve ser instalada pela companhia telefônica no ponto que recebe a ligação e no ponto que faz a ligação.
