摘要

#CMT# #/CMT# The method is for the determination of the time delay in the report of an occurrence of a communication fault in at least one communication unit to be tested out of a number of such interconnected units in a network. The alarm system (1) used involves a number of components connected to a telecommunication network (8). An alarm transmission station (3) is connected to a network nodal point (12), and can send signals to alarm central control (5) connected to a network nodal point (10). The alarm system has a control center (7) connected to a network node point (11). The network contains four nodal points, mutually connected to each other (9,10,11,12). #CMT#USE : #/CMT# For the determination of the time delay in the report of an occurrence of a communication fault in at least one communication unit. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure presents the alarm system as per the invention, with which it is possible to deduce the method of operation. 1 : Alarm system 3 : alarm transmission station 5 : Alarm central control 7 : Control center 9,10,11,12 : nodal points.
