The KDE desktop is represented by the “kde-workspace” and “plasma-desktop” packages and the Xfce desktop by the “xfdesktop” package. The control unit is thus replaced – the user’s point of view – a logical network of machines.
: Put the fun back into computing. Use Linux, BSD.
The description was made of the system and the overall defense scheme helps to understand how are made the already mentioned functions of detection, defense, locating faults, signaling, helps repair. For this purpose ccours 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.
Please select two distributions and then a specific version of each distribution to compare.
We find the functions for a division into three levels: Disques d 1d2 ; tent of couplers C 1, C 2, 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 Paxb and terminal units UT couplers.
Naturally oscillators have their own fault detection means. It is particularly applicable in the industries of telecommunications and telematics.
For example, suppose a group of GUT terminal units is supervised by a CPU control unit which performs a cyclic scanning autocommutatfur all terminal units UT it supervises.
For reasons of defense and modularity, the connections between the central switching network and the groups of terminal units GUT, GUC and control are organized in bundles F Figure 1each beam combining two multiplex links, a link distribution of clock and synchronization link.
Compare Packages Between Distributions. Alarm monitoring arrangements for digital telecommunications switching networks. 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.
Figure 3 shows an example of MD signal distribution module. Autocokmutateur 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 two clock and synchronization circuits CBT of a group are connected to different planes of the switching network and distribution modules independent MD signals. Autocommutwteur AM module is tested by looping the information on a time interval of each control channel.
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. In the case of controlled exchanges by the central computer, technical more developed in autocommutwteur 70s, the defense is centralized: The fault messages are transmitted to the logical machine management control network filter before signaling.
Telecommunication switch having programmable network protocols and communications services. 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. The MTA call processing logic machine control in applicant stall phase, active control of the conversation path including the network.
The configuration shown includes the system management tasks and exchanges mentioned above, and designated SGTE, and the following logical machines: Each pair the signals are transmitted in a bipolar mode. These tests are performed by robots located in units of special terminals. A defense device of a distributed control PABX.
La figure 3 montre un exemple de module de distribution de signaux MD. These principles are applied to all types of terminal units: En outre les modules correspondants sont desservis par des alimentations distinctes.

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.
An example of unit of subscriber terminals is shown in Figure 2.
Asymmetric digital subscriber line provision flow control on digital subscriber line access multiplexer switches. Special Task alarm management and TGA an alarm panel. A control unit UC is shown schematically in Figure 5. We now know the advantages of distributed control systems, due in particular benefits to changing mieroproces- sors and software.
The autockmmutateur beams F serving the same body are completely independent because their links come from different planes. One can thus increase the capacity of the Autoocmmutateur by adding additional control units. In addition the corresponding modules are served by separate power supplies.
Method and system for providing redundancy for signaling link modules in a telecommunication system. The logical machine MLR management control network provides runtime control by delay. Each D1 binding Dr comprises a clock and a synchronization signal. The software is distributed by the nature of the system.
