Abstract

LA CAJA DE CONEXION (300) DE UN SISTEMA DE TRANSMISION DIGITAL DE INFORMACION (201) PARA UNA TRANSMISION BIDIRECCIONAL DE SEÑALES DE INFORMACION ENTRE, P. EJ. UNA CENTRAL TELEFONICA (VS1, VS2) Y ABONADOS, TIENE UNIONES ELECTRICAS CONTROLABLES ENTRE LAS CONEXIONES CON LAS CENTRALES TELEFONICAS (VS1, VS2) EN EL PUNTO DE INTERSECCION (A) Y LAS CONEXIONES CON LOS ABONADOS (313) EN EL PUNTO DE INTERSECCION (B). EL PUNTO DE INTERSECCION (A) ES, PREFERENTEMENTE, UN PUNTO DE INTERSECCION PARA UNA SEÑAL MULTIPLE DE TIEMPO CON UNA FRECUENCIA DE TRANSMISION DE 2MBIT/S; EL PUNTO DE INTERSECCION (B) ES UN PUNTO DE INTERSECCION PARA SEÑALES MULTIPLES DE TIEMPO (TDM/TDMA). LA MEMORIA INTERMEDIA (303) DEL SISTEMA TDM/TDMA SE COMPONE DE MEMORIAS PARCIALES (11, 12, 13, 14...; 21, 31, 41,...) DISPUESTAS EN FORMA DE MATRIZ. LAS MEMORIAS PARCIALES (11, 12, 13, 14..; 21, 31, 41...) SE USAN AL MISMO TIEMPO COMO MEMORIAS INTERMEDIAS PARA LA CONEXION DE VIAS.
