Description

 The invention relates to automatic switching and can be used to build nodes for automatic switching of quasi-electronic automatic telephone exchanges of small and medium power.

 Known switching systems containing m nodes of incoming communication and m nodes of outgoing communication, each of which contains n blocks of switching of the first link. n switching units of the second link, as well as an additional switching unit (RU, patent N 2041570, CL H 04 M 3/00, 1995). This system allows you to reduce the blocking of ordinary subscribers and to eliminate privilege blocking (priority) subscribers. However, this system does not allow subscribers to have additional types of services related to access to the data bank.

Known switching systems containing m nodes of incoming and m nodes of outgoing communication, each of which contains n blocks of switching of the first link and n blocks of switching of the second link, an additional switching block and a storage unit and storage of information (RU, patent N 2041567, class H 04 M 3/00, 1995). The system allows providing subscribers with additional types of services related to access to the data bank, however, a large number of information storage and delivery units, the number of which is equal to the number of incoming and outgoing communication nodes (2 _m ), containing the same information, significantly increases the cost of the system.

 The technical result achieved by the invention is to simplify the system while reducing its cost.

 The drawing shows a structural electrical diagram of a switching system, storage and processing of information.

The system for switching, storing and processing information contains n switching blocks of the first link 1 ₁ - 1 _n , n switching blocks of the second link 2 ₁ - 2 _n , additional switching blocks 3, the storage and output unit 4, m incoming communication nodes 5 ₁ - 5 _m and m outgoing nodes 6 ₁ - 6 _m .

 The system of switching, storage and processing of information works as follows.

A call coming from a regular subscriber arrives at the corresponding switching unit of the first link 1 ₁ - 1 _n-1 , corresponding to the incoming communication node 5 ₁ - 5 _m . From the output of this switching unit of the first link 1 ₁ - 1 _1-n , a connection is made with the required switching unit of the second link 2 ₁ - 2 _n . If you want to make another connection between these units, it is made through an additional switching unit 3. Thus, the throughput for ordinary subscribers is doubled.

Privileged subscribers are included in the nth switching unit of the first link 1 _n . For communication with other subscribers of the same category, L lines are allocated connecting the n-th switching blocks of the first and second links 1 _n and 2 _n incoming nodes 5 ₁ - 5 _n and n-1 lines connecting n switching blocks of the first and second link 1 _n and 2 _n in the communication nodes of the outgoing communication 6 ₁ - 6 _m . Thus, blocking for privileged subscribers is unlikely. In addition, these subscribers can communicate with ordinary subscribers through an additional switching unit 3. Privileged subscribers have an additional service, namely that they can connect to the information storage and delivery unit 4, record and receive information from it. This block can be made in the form of a computer or other database.

Each n-th switching unit of the first link 1 _{n of} each of the m incoming communication nodes is connected to the information storage and output unit by 4, nL-2 lines, and therefore the number of inputs and outputs of the information storage and output unit is m (nL-2) . Since the unit for storing and issuing information 4 is one, the cost of the entire system is quite small, and privileged subscribers can access it without significant locks.
