Abstract
EN UNA UNICA RED DIGITAL DE SERVICIOS INTEGRADOS ESTANDAR INTERNACIONAL (ISDN), SE DISPONE UNA INTERFAZ DE REGIMEN BASICO (BRI) DE MANERA QUE PUEDAN OPERARSE SIMULTANEAMENTE UNA TERMINAL DE DATOS Y DOS TERMINALES DE VOZ, TRES TERMINALES DE VOZ O CUATRO TERMINALES DE VOZ A TRAVES DE LA INTERFAZ. LOS CONVERTIDORES DE CODIGO (65, 66) ASOCIADOS CON LAS TERMINALES DE VOZ (24-29) Y CON UN CONMUTADOR DE OFICINA CENTRAL (30), CONVIERTEN AL CODIGO DE MUESTRA DE VOZ DE OCHO BITS, PROVENIENTE DEL TERMINAL DE VOZ O DEL CONMUTADOR DE LA OFICINA CENTRAL, EN UN CODIGO DE MUESTRA DE VOZ DE CUATRO BITS LO QUE PERMITE QUE LAS CORRIENTES DE BITS PROVENIENTES DE DOS TERMINALES DE VOZ SE MEZCLEN Y PUEDAN SER TRANSMITIDAS A TRAVES DE UN UNICO CANAL B EN LA INTERFAZ. CUANDO SE OPERAN DOS TERMINALES DE VOZ SIMULTANEAMENTE A TRAVES DE UN CANAL B, CADA UNO DE ESTOS TERMINALES POSICIONA MUESTRAS DE VOZ CODIFICADAS EN CUATRO BITS EN UN SUBCANAL B DEL CANAL B Y RELLENA 4 BITS EN EL OTRO SUBCANAL B. SE CONVIERTEN LAS MUESTRAS DE VOZ CODIFICADAS A CUATRO BITS PROVENIENTES DE LOS SUBCANALES B EN MUESTRAS DE VOZ EN LOS TERMINALES DE VOZ Y EN MUESTRAS DE VOZ DE CODIGOS DE OCHO BITS EN EL CONMUTADOR DE LA OFICINA CENTRAL.
