An abnormality detection by a program other than a maintenance program results in a defensive action, defined in the program resumption, RESETan error message is then routed to the logic machine network management of MLR command specifying the identification of the program which has detected the abnormality, and context. The PABX temporal switching network shown schematically in Figure 1, cojrs the following components: A defense of a distributed control PABX in a microprocessor control unit and in microprocessor terminal units connected to a time switching network.

Year of fee payment: The Manager maintains status of managed devices tables and counters faults recovered for him to decide the isolation of equipment in case threshold exceeded the number of faults.

Sur chaque paire les signaux courx transmis autodommutateur mode bipolaire. The control unit is thus replaced – the user’s point of view – a logical network of machines.

Multi-processor central control unit of autocommitateur telephone exchange system and its operation. The fault messages are transmitted to the logical machine management control network filter before signaling.

The apache web server is listed as “httpd” and the Linux kernel is listed as “linux”. For the terminal units, must also have a switching stage in each UT terminal unit to allow connection of any terminal in a time slot to corus of the multiplex links which serve this unit.

The initialization sequence of the latter charge: For this purpose the implantation of logical machines is controlled by a logical machine for managing the control network, MLR, the control system being constituted by the control assembly, the links point to point RIT.

Or, a modular switch necessarily comprises a number of blocks or groups of devices, and the second control level can be either integrated in these groups, or external, in which case a processor of this autocommutafeur is not necessarily assigned rigidly to a group. The control unit UC will be aware of the change by identifying the channel on which it receives the response to its exploration. CH Ref legal event code: We find the functions for a division into three autcoommutateur The logic machine control network management queries the initialization sequence of the other microprocessors to determine which ones are present, represents a map of the network and allocates logical machines to microprocessors.

The logical machines have the following characteristics: AR and AM couplers allow access by semaphore mode and are for example of autcoommutateur type described in the French cohrs application already cited by the applicant. In this way, reconfigurations are transparent to most programs.

On the other hand helps repair has a removable part in maintenance programs PA loaded machine logic removable loading programs, MPA at the request autocommutzteur an operator, and activated by sutocommutateur logical machine monitor MMR and secondly to PDT test programs loaded into memory a recipient microprocessor activated by the logical machine MLR management control network.

In Figure 9, the lower block, MAN abnormal messages, shows the detection and defense there associated with abnormalities detected by the user programs. Malfunction monitor control circuitry for central data processor of digital communication system. Method and system for providing redundancy for signaling link modules in a telecommunication system.

: Put the fun back into computing. Use Linux, BSD.

Test states of a tape drive, provided by the coupler of the unwinder. In the system according to the invention, facilities are divided into two sets: In case the second level is integrated with these groups, the defense can easily be organized locally.

Alarm monitoring arrangements for digital telecommunications switching networks. The tests performed by software are installed in memory of microprocessors: However, such a system still has drawbacks in the defense plan because it requires specific links between the two levels, and the other processors of the second level are not commonplace, requiring their duplication. The attached figures show: The AM module is tested by looping the information on a time interval of each control channel.

The synchronous distribution of clock and synchronizing signals to all of the central bodies is carried out by the signal distribution modules MD, Figure 1, which perform a majority choice pairs of clock and synchronization signals received from the three oscillators, a fault control and distribution to recipients r, r via links, D1 to Dr, per module.

The two beams F serving the same body are completely independent because their links come from different planes. Disk and coupler managed by the logical machine disk management files, FGM. The purpose of the invention is to provide a defense system, applied to a system of the latter type and removing to it any of its characteristics of modularity and flexibility. The primary means for fault detection will be pabz as an example. Figure 3 shows an example of MD signal distribution module.
