Manner of control panel operation and telephone exchange system

The subject of the invention is a method of controlling the operation of a telephone exchange, and in particular a method of obtaining information about the states of line systems and central units needed to control these units and systems.

The method according to the invention is particularly applicable to telephone exchanges with commutation in a time division system. The invention also includes a time-division switched telephone exchange system, in particular an internal telephone exchange system.

There are also known system solutions of telephone exchanges working with commutation in a system with a time division.

A system of exchange is known in which subscriber units and central units are connected to a common telestrada. These units are also connected directly to the processor. In such a system, the processor directly controls the operation of all central units using the multiplexing technique. The processor cyclically addresses the central units taking part in the connection, causing their activation. In such a solution, the possibility of handling telephone traffic depends directly on the speed of the processor. A faster processor is required to handle higher volumes of traffic.

In the method according to the invention, linear systems and central units are examined cyclically and simultaneously, the address of a specific linear system or central unit is determined, then this information is transferred to the information set from where the data is downloaded for processing at any time.

In the control panel system according to the invention, the line systems are connected to one address output of the tracking system, the second address output of which is connected to the central units. These units are connected to the information input of the transient register system, to which both address outputs of the searching system are connected. Between the output of the transient register system and the control data input of the central units, the data processing system and the central registers are connected in series. In such a control panel solution, the processor is not involved in activating the hardware units, which increases the commutation speed, and at the same time the processor can be fully used to increase the connection and functional capabilities of the control panel.

The invention will in the exemplary embodiment shown in the drawing, which shows a block diagram UKB ^{d y} in ^k centrah tectonic with omutacj ^± system ^{to the} p ^clad em the times ^y m.

As shown in the figure, line systems 1 and central units 2 are connected to the telestrada 7. The line systems 1 are also connected to the address output of the searching system 3. Central units 2 are connected to the address output b of this system. Both address outputs a and b of the tracking system 3 are connected to the address input d of the transient register system 4. Central units are connected to the information input c of this system. The output of the transient registers system 4 is connected to the data processing system 5, which through central registers 6 is connected to the control data input e of central units 2.

In the exchange according to the invention, the development of data for the control of switching processes is programmed, and the execution of decisions and the collection of information are systematic. The probing system 3 generates sequentially and cyclically addresses of central units 2, activates these units, enabling them to commutate, with common for each type of units, transition registers 4 and further with the data processing system 5. The information obtained as a result of the scanning is transferred to the system of transition registers 4 synchronously , that is, at strictly defined time intervals. The collection of data by the data processing system 5 follows the so-called interrupt principle. Each type of central unit 2 has a specific interrupt level.
