Electronic switching systems
Professionals dealing with telephone switching systems are well aware of the problems with program control of modern electronic telephone exchanges. It is not always possible to pay for high-quality switching systems, so you have to use cheaper options.
One of such examples is the electronic telephone exchange of a Ukrainian factory located in the city of Kharkov. The switching system of the EU-11 type has become widespread throughout Ukraine across all regions, both among Ukrtelecom PBXs and in private offices and large enterprises.
The configuration of the switching system makes it possible to obtain both the terminal station and the backhaul. Almost everyone who operates a telephone exchange of this type encountered the same problems. The main one is a significant lag in software from the element base and electronic filling. The Lviv company is engaged in software development, because the introduction of new programs is very slow. Without actual modernization of TEZs, software versions are changed from one version to another, which negatively affects the processor load, the stations malfunction.
Malfunctions in the work of stations are not noticeable to personnel with a low level of qualification, but having an additional program for monitoring the operation of the station, you can notice peaks and failures in the load of processors of the control complex.
We found the best solution to this problem. The main mistake of most programmers involved in the registration of types of sets, internal and external numbering is too complicated approach to parsing numbers. The volume of the parsing file often exceeds 85 percent of the maximum file size allowed by the station’s memory, which greatly affects the load on the control processors. By reducing the file size to 70 percent, we reduced the peak time by six times!
Analysis of the number can be carried out both in the dietary supplement and in the BCC. Here you should choose the best option, the sets that do not have differences for different dietary supplements, you need to disassemble only in the BCC, and not duplicate in the dietary supplements, that is, we release the set according to the first or second digit in the BCC. By this, we reduce the parsing files of the number.
Another important point. During long-term operation, errors accumulate in the program, which are not visible by the alarm, but increase the number of cases when the connection to the subscriber fails, although the acoustic signal “CPV” exists. In this case, the easiest way is periodic (once a month) cleaning of TEZs by pressing the "reset" button.
The most convenient version in the work of META-TG, this version allows you to change the program in the "hot" mode, without interruption of the station, as it was in older versions (about 5 minutes).
