Abstract

PROCEDIMIENTO PARA EL DESARROLLO DEL SERVICIO DE COMUNICACONES, EN REDES TELEFONICAS, DE CENTRALES SECUNDARIAS CON SUBINSTALACIONES AUTOMATICAS, MEDIANTE INTERCAMBIO DE SEÑALES DE CONMUTACION. CONSISTE EN EMPLEAR SEÑALES DE AUDIOFRECUENCIA Y DE CORRIENTE ALTERNA, ENTRE LA CENTRAL SECUNDARIA (HA) Y LA SUBINSTALACION (UA), TANTO PARA EL ESTABLECIMIENTO Y ANULACION DE COMUNICACIONES COMO DURANTE LA EXISTENCIA DE ESTAS. LA DESCONEXION SE EFECTUA MEDIANTE UNA SUCESION DE SEÑALES (HKA Y HKE) QUE DEPENDE DE LA DIRECCION DE ANULACION DE LA CONVERSACION.
