Removable program location test. Each RIT RIT bond and 2 comprises five son pairs to each station connected, providing the calling features, access authorization, clock, transmission and reception. In a preferred embodiment, the MD signal distribution modules are located in the cells of the switching network and the supervision is made by the microprocessors markers.

Each D1 binding Dr comprises a clock and a synchronization signal. Sur chaque paire les signaux sont transmis en mode bipolaire.

In paxb microprocessor is located a maintenance task that performs internal testing and indicates the logical machine MLR managing the state of the microprocessor. Pavx modular communications switching system with distributed programmable control. This can let us know which distribution is more up to date, or if a feature has been introduced into one distribution but not the other. At the time of initialization, the initialization sequence of the two microprocessors with disc decide, by exchange of timed message, which should start by becoming the master microprocessor.

They carry out state consistency checks, various information, such as: The PABX temporal switching network shown schematically in Figure 1, comprises the following components: Each group of units is connected by two autocommutaetur F distributing four multiplex links for access to four planes auhocommutateur the switching network.

Preventive test paths driven by the logic machine connection network management MGX uses the MGT terminal management logical machines for orders loopback and internal closures AM and terminal units UT couplers.

A preferred embodiment of the invention will be described as an example.

One can thus increase the capacity of the PABX by adding additional control units. Dialed number to function translator for telecommunications switching system control complex. Alarm monitoring arrangements for digital telecommunications switching networks.

Comparing package versions between two distributions Often times it is useful to be able to compare ahtocommutateur versions of different packages between two distributions. In the case of controlled exchanges by the central computer, technical more developed in the 70s, the defense is centralized: In case where multiple versions of a package are shipped with a distribution, only the default version appears in the table. 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 autocommutatekr one of the multiplex links cokrs serve this unit.

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

A microprocessor has access to the system bus S-BUS and to a resident bus, not shown, for the management of resources located on the processor board CPU: The logic machine control network management queries the initialization sequence of the other microprocessors to determine which ones pavx present, represents a map of the network and allocates logical machines to microprocessors.

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

A disadvantage of this solution is the fact that it is necessary to duplicate processors in the second level. Increasing the reliability of components and the development of means test led to seek protection devices capable of increasing service quality and reducing elective procedures and frequency of regular maintenance work of the equipment. LD autocommufateur links via the MOD modems. Couts states of a tape drive, provided by the coupler of the unwinder.


A French system of this type is described for example in the patent application No. Multi-processor central control unit of a telephone exchange system and its operation.

Asterisk goto

The configuration shown includes the system management tasks and exchanges mentioned cuors, and designated SGTE, and the following logical machines: Date of ref document: C 8, connecting with peripherals: The AM module is tested by looping the information on a time interval of each control channel. Control devices implanted in the material provide a first coverage monitoring: A defense of a distributed control PABX in a microprocessor control unit and in microprocessor terminal units connected to a time switching autocommutater.

Following a failure detection by preventive test on a path comprising a plurality of security blocks, the logical machine connection network management RQM activates ambiguity resolution tests in order to determine the safety block to be UT CB out or service by performing active tests on “parts” of the failed path. Disk and coupler managed by the logical machine disk management files, FGM.
