Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch configuration method, particularly to a switch configuration method applied to a communication path switch network of a common control type automatic exchange.

A call path switch network of a common control type automatic exchange such as an electronic exchange exchanges and connects an incoming line and an outgoing line of a two-wire system or a four-wire system using a large number of switching elements.
In order to reduce the number of switching elements that make up the communication path switch network when there are a large number of incoming lines and outgoing lines to be exchanged and connected, for example, a grid that interconnects 8 incoming lines and 8 outgoing lines is used as a unit. A so-called multi-stage link configuration in which a plurality of grids are connected by links is widely used.

FIG. 1 is a connection diagram showing an example of conventional switch elements constituting such a grid. In FIG. 1, the switch element SU has 16 mechanical make contacts 1 to 16 and 16 electromagnetic or electronic drive sources (not shown) for opening and closing each make contact. The static contact terminals of each make contact are output to the outside of the switch element SU as independent terminals T1 to T16, respectively. On the other hand, each movable contact terminal of odd numbered contacts 1, 3...15 and even numbered contacts 2, 4...16
Each of the movable contact terminals is connected in multiple ways, and the switch element SU is connected as common terminals T17 and T18.
Output to the outside. FIG. 2 shows an example of a method for configuring a two-wire two-stage link switch using such a switch element SU in a communication path switch network of an electronic exchange. In FIG. 2, the independent terminals T1 to T16 of the eight switch elements PSU11 to PSU18 whose configuration is shown in FIG.
A ×8 primary lattice PG1 is constructed. Similarly, a total of eight primary gratings including the primary grating PG8 constituted by switch elements PSU81 to PSU88 are constructed. Similarly, 64 switch elements SSU
11 to SS88, 8×8 quadratic grid SG1
SG8 to SG8 are configured. Eight 2-wire incoming lines are connected to the double-connected independent terminals T1 to T16 of each primary grid, and eight 2-wire outgoing lines are connected to the double-connected independent terminals T1 to T16 of each secondary grid. Connect to the line. Further, the common terminals T17 and T18 of the eight switch elements constituting each of the primary gratings PG1 to PG8 and each of the secondary gratings SG1 to SG8 are 64
The paired links L11A/B to L88A/B interconnect each other to form a single link configuration as shown in FIG. As a result of the above, 2-wire input line 1 for 64 lines
A two-stage link switch network is constructed that connects 1A/B to 88A/B and 64 two-wire output lines 11A'/B' to 88A'/B'.

As is clear from the above description, in the conventional switch configuration method using the switch element SU, it is necessary to interconnect the switch element connecting the incoming line and the switch element connecting the outgoing line with a link. Therefore, it is necessary to provide common terminals T17 and T18 for each switch element SU, which makes the structure of the switch element complicated and large. Also, the switch element
The shape of the communication path switch network constituted by SUs also becomes large, and as the scale of the communication path switch network becomes larger, the link connection work becomes enormous.

The object of the present invention is to eliminate the drawbacks of the conventional switch construction methods as described above, to realize a switch construction method that is simple in structure and effective for miniaturization, and that can further reduce link connection work.

This purpose is to
One terminal of the switching element that opens and closes between the terminals is double-connected within the switch element, and the other terminal is independently outputted to the outside of the switch element, and some of the independent terminals of the plurality of switch elements are connected. The remaining independent terminals of the plurality of switch elements are used as incoming connection terminals, and the remaining independent terminals of the plurality of switch elements are used as outgoing connection terminals, and the plurality of switch elements are divided into one or more first groups, and the switches in each first group are Multiple incoming lines are connected to the incoming line connection terminals of the elements, and the plurality of switch elements are divided into one or more second groups different from the first group, and the switch elements in each second group are A plurality of outgoing lines are connected to the outgoing line connection terminal, and connected to a first grid determined by the number of incoming lines connected to each of the switch elements and the number of switch elements constituting the first group, and each of the switch elements. This is achieved by link-connecting a second grid determined by the number of outgoing lines and the number of switch elements constituting the second group using the multiple connection terminals within the plurality of switch elements.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 6. FIG. 3 is a connection diagram of a switch element according to an embodiment of the present invention, and FIGS.
The figure is a diagram showing a switch construction method according to an embodiment of the present invention using the switch element shown in FIG. 3, and FIG. 6 is a diagram showing the basic concept of a switch construction method according to an embodiment of the invention. In FIG. 3, the switch element SU has 16 mechanical or electronic make contacts 1 to 16 and 16 for opening and closing each make contact.
and a driving source (not shown). The static contact terminals of each make contact are output to the outside of the switch element SU as independent terminals T1 to T16, respectively. On the other hand, the movable contact terminals of the make contacts 1 to 16 are connected in multiple ways by multiple connections M within the switch element SU, and are not output to the outside of the switch SU. FIG. 4 shows a switch configuration method according to an embodiment of the present invention, in which eight two-wire incoming lines and eight two-wire outgoing lines are connected using such a switch element SU. In Figure 4, the switch whose configuration is shown in Figure 3 is
Make contacts 1 to 16 of SU3 and SU4

The B lines 1B' to 8B' of the two-wire system output lines are connected to the four independent terminals T9 to T16. Now entering line 1A/
When a request to connect 1B and outgoing wires 1A'/1B' arises, by operating make contacts 1 and 9 of switch elements SU3 and SU4, respectively,
The desired connection is achieved via a double connection M in both switches SU3 and SU4. Similarly, connection between any incoming line and any outgoing line is made using switch element SU3.
By simultaneously operating the connected make contacts of the input line and the output line of SU4,
This is achieved via a double connection M in switch elements SU3 and SU4.

Next, based on the switch configuration shown in Figure 4,
Similar to FIG. 2, FIG. 5 shows a two-stage link configuration method according to an embodiment of the present invention, which connects 64 lines of two-wire incoming lines and 64 lines of two-wire outgoing lines. Note that in FIG. 5, as in FIG. 4, the connection for the A line and the connection for the B line of the two-wire incoming and outgoing lines are performed in complete contrast, so the switch related to the A line connection is Only the configuration is clearly shown, and the B line connection relationship is omitted. The following explanation will also be made regarding the A line connection relationship. In FIG. 5, eight switch elements SU11A to SU18 whose configuration is shown in FIG.
The independent terminals T1 to T8 of A are each connected in multiple ways to form an 8×8 primary lattice PG1. Similarly, the independent terminals T1 to T8 of 64 switch elements are connected to switch elements SU81A to SU88A.
A total of 81 primary lattices PG1 to PG8 are constructed by multiple-connecting each of the 8 switches to 8 switches. Next, the remaining independent terminals T9 to T16 of each switch element are connected to the switch elements SU11A to SU81.
A, ..., SU18A to SU88A are connected in multiple ways for 8 pieces, and 8 x 8 secondary grids SG1 to SG8 are connected to 8
Configure. With the above configuration, the primary lattice PG1
PG8 to PG8 and secondary gratings SG1 to SG8 are composed of 64 switch elements SU11A to SG8, as shown in FIG.
The double connection M in SU88A automatically connects them to form a single link configuration. Each primary grid PG1
Double-connected independent terminals T1 to T of PG8 to PG8
8, 2-wire input A lines 11A to 18A,...
..., 81A to 88A are connected to eight lines, and the two-wire output A lines 11A' to 18A', ..., 81A are connected to the double-connected independent terminals T9 to T8 of each secondary grid SG1 to SG8. ' to 88A' are connected to eight lines. By using it together with the B line related switch configuration of exactly the same type, 64 lines of 2-wire input line 11

A two-stage link switch network connecting 1A'/B' to 88A'/B' is constructed. In the switch network, when a request to connect incoming lines 11A/B and outgoing lines 11A'/B' arises, the primary lattice to which the incoming lines 11A/B and outgoing lines 11A'/B' are connected is
Switch element spanning PG1 and secondary lattice SG1
Focusing on SU11A and SU11B, the desired connection can be made between the switch elements by simultaneously operating make contacts 1 and 9 as in FIG.
It is configured via a double connection M in SU11A and SU11B. Similarly, when connecting any incoming line and any outgoing line, the related primary lattice and secondary
This is achieved by focusing on the switch elements spanning the next grid and performing the same operation as in FIG. 4.

Although the above explanation has been made in comparison with a conventional switch construction method in order to easily understand the principle of the embodiment, the true intention of the present invention is to use a switch element SU as shown in FIG. A conventional switch network could be configured as shown in FIG. That is, conventional switch construction methods have mainly been constructed using grids and link connections, but the switch construction method according to the present invention focuses on switch elements and connects incoming and outgoing wires in multiple ways as appropriate, allowing for arbitrary configuration. Since it can have a switch configuration, it can be expressed using a more general notation. In FIG. 6, the switch element SU (FIG. 6a) having eight make contacts is treated as the configuration shown in FIG. 6b, and
By connecting the incoming lines 11 to 14, the incoming lines 21 to 24, the outgoing lines 11' to 14', and the outgoing lines 21' to 24' in multiple ways to the four switch elements SUA' to SUD' as shown in FIG. An equivalent switch configuration is realized as shown in . Similarly, Figure 6c
The sixth switch element SU has four switch elements SU configured as shown below.
As shown in Figure e, 12 incoming lines 11 to 16 and 21 to 26 and four outgoing lines 11', 12', 2
By double connecting 1' and 22', the 6th
An equivalent switch configuration is implemented as shown in Figure g. In addition, in the configuration method shown in Figure 6, the conventional link connection is included in the switch element SU, so even in the case of expansion, a switch is added to support the link connection, and there is no uneconomical effect due to imbalance, and the link It exhibits features such as eliminating the need for wiring work.

As is clear from the above description, according to this embodiment, any two-wire incoming line and any two-wire outgoing line are
By closing the make contact of the switch element to which these incoming and outgoing lines are connected, the connection is made via a double connection within the switch element, and there is no need to provide a link as in the conventional switch configuration method. . Therefore, each switch element does not need to output a common terminal for link connection to the outside, and the communication path switch network constituted by the switch elements does not require link connection work.

Note that FIGS. 3 to 6 are only one embodiment of the present invention, and for example, the 16 make contacts 1 to 16 included in the switch element SU are divided into test point groups and 2, respectively. Although the present invention is not limited to a single make contact and may be modified, for example, by dividing the contact into 12 or 4 make contacts, the effects of the present invention remain the same in either case. Further, the number of make contacts included in the switch element SU is not limited to 16, and the effects of the present invention will not change even if the number is arbitrary and suitable for the configuration of the channel switch network. Further, the constructed communication path switch network is not limited to a two-wire system, and even if it is a four-wire system or any other arbitrary configuration, the effects of the present invention will not change. Note that the switching element included in the switch element is not limited to a mechanical make contact.

As described above, according to the present invention, the connection between the incoming line and the outgoing line is achieved by a double connection in which the switching element inside the switch element and one end thereof are connected in a double way inside, and the switch element is provided with a common terminal for link connection. It is not necessary, and the structure is simple and compact. Furthermore, the communication path switch network constituted by such switch elements is also made smaller, and the link connection work is reduced.
