Next, one apparent vertical path of the switch matrix is switched by a switching relay arranged horizontally and horizontally, and used as two vertical paths of functional soil, and the above-mentioned primary switch matrix and secondary switch matrix are connected. A switch network construction method is known in which the vertical paths of the two are connected together.

If this known switch network configuration method is configured by arranging relays at each crosspoint without using a crossbar switch, the circuit configuration will be as shown in FIGS. 1 and 2.

In other words, relays with two sets of contacts that can be used as cross points are connected in a matrix, with 8 relays in the horizontal direction and 4 in the vertical direction, and a switching relay is provided on the vertical road side, and the relays are connected up and down on the horizontal road. The above-mentioned relays are connected in a matrix with four relays in the horizontal direction and eight in the vertical direction of the matrix, and a switching relay is provided on the horizontal road side, and the vertical road is When configuring a two-stage link connection in which there are two groups of primary switch matrices and two groups of secondary switch matrices by using vertical path left/right switching matrices that can be used by switching to the left and right, and the required number of each, If the conventional method using a crossbar switch is adopted as is, the connection method of the switch matrices (communication path matrix) that make up the communication path will be as shown in Figure 1, and each switch matrix shown in Figure 1 will be driven.

That is, as shown in FIG. 1, a primary switch matrix (switch matrix consisting of LSO to LS3) and a secondary switch matrix (switches consisting of TSO, TSL, etc.) constituting the communication path matrix. The vertical levels of the first switch matrix (the group consisting of LS1 and LS3, that is, the odd numbered group) are connected in duplicate for each group and level, and half of the vertical levels of the first switch matrix (the group consisting of LS1 and LS3, that is, the odd number group) are The first group of the next switch matrix (TS

The two-stage link connection method described above, which replaces the switch network of the conventional crossbar exchange with relays, has a drive path matrix in which each matrix constituting the primary drive coil matrix and the secondary drive coil matrix Although there is an advantage that multiple vertical path drive levels can be connected to each level, cross-point relay drive circuits must be provided separately for the primary drive coil matrix and the secondary drive coil matrix, and In order to selectively connect the cross-point relays to be closed or opened to the drive circuit, in addition to the contacts of the channel selection relays, the contacts of the even-numbered group selection relays of each sweet matrix in the communication path matrix and There is a drawback that the configuration of the equal-pass selection circuit is complicated, since it is necessary to use the contacts of the odd-numbered group selection relay.

A switch is connected to the vertical path (or horizontal path) of the primary switch matrix (consisting of contacts of a relay).

) so that the apparent one horizontal path level (or vertical path level (c)) can be used functionally as two horizontal path levels (or vertical path levels), and similarly the horizontal path level of the secondary switch matrix. A changeover switch (consisting of relay contacts) is placed on the road (or vertical road) to convert the apparent one vertical road level (or horizontal road level (c)) into functionally two vertical road levels (or horizontal road level). The link connections between the primary switch matrix and the secondary switch matrix are configured as follows: vertical path level (or horizontal path level) of the secondary switch matrix. Among levels (c), one group of the vertical path level (or horizontal path level) and the primary switch matrix that can be connected to the horizontal path (or vertical path) by the operation of the changeover switch, e.g. A vertical road level (to which a link connection is made between the vertical road level (or horizontal road level) of the odd numbered group, and connection to the horizontal road (or vertical road) is possible when the changeover switch is inoperative) or horizontal path level) and the other vertical path level (or horizontal path level) of the other even-numbered group of the primary switch matrix.
Drive path matrix: In the above communication path matrix, in the drive path matrix of the primary switch matrix in which the switching level node is on the link side, the vertical path and drive level (or horizontal path drive level) are divided into two types for each level across all groups. In the drive path matrix of the secondary switch matrices where the non-switching level is the link side, the vertical path and drive level (or horizontal path drive level) are connected in duplicate for each level in each group, and the primary switch The vertical path drive level (or horizontal path drive level) of the drive path matrix that drives the matrix is divided into two, and each is divided into two vertical path drive levels of each group of drive path matrices that drive the secondary switch matrix. (or horizontal path drive level), the Talos point relays to be driven in the primary switch matrix and the secondary switch matrix are operated in series (in a skewered manner).
