Abstract

PROCEDIMIENTO DE ACCESO DE UNIDADES DE TRATAMIENTO DE DATOS A UNA LINEA GENERAL DE DATOS. CADA UNIDAD (21, 22, 23) SE AUTOASIGNA NUMEROS DE SECUENCIA PARA FINES DE IDENTIFICACION. LA UNIDAD QUE TIENE EL NUMERO DE SECUENCIA MAS BAJO OBTIENE ACCESO INMEDIATO A LA LINEA GENERAL (21) Y PUEDE RENUNCIAR A LA UTILIZACION DE LA LINEA GENERAL TRANSMITIENDO UNA PALABRA DE CONTROL, O INDICATIVO, CON UN NUMERO DE SECUENCIA INCREMENTADO. TODAS LAS UNIDADES RECIBEN EL INDICATIVO, PERO SOLAMENTE LA UNIDAD QUE TIENE EL NUMERO DE SECUENCIA INCREMENTADO OBTIENE ACCESO A LA LINEA GENERAL. EL PROCEDIMIENTO PERMITE EL FUNCIONAMIENTO CONTINUO DEL SISTEMA SI SE AÑADEN O SE ELIMINAN UNIDADES, SIN INTERRUMPIR EL FUNCIONAMIENTO DE LA LINEA GENERAL.
