ABSTRACT:
The invention concerns an arrangement for the supervision of a number of devices belonging to a group of devices in a telecommunication system, concerning seizure statistics, i.e. the ratio between the number of normal seizures and the total number of seizures, which devices, (relays, relay sets, registers etc) alternately are seized and released. Two counters are connected to each of the individual devices, a first counter for the registration of the total number of seizures of the device, and a second counter for the registration of the number of seizures of the device exceeding a certain minimum time. A first quotient between these numbers is periodically established for each individual device. A first adder adds the total number of seizures for each device belonging to the device group. A second adder adds the number of seizures exceeding a certain minimum time for each device in said the group. A second quotient is established between such two numbers concerning the whole device group. In a comparing circuit a comparison is made in turn between said first quotient for the individual devices and said second quotient. An alarm arrangement delivers alarm signals when the difference between these quotients exceeds a certain value.
