The present invention relates to a method for connecting a signal line allocated to itself among signal lines in a plurality of subunits connected to a plurality of signal lines in a cascade structure, each of which performs the same function. In particular, each subunit is located at a certain position on the cascade structure. The present invention relates to a method for internal wiring in cascaded cascade units to be able to connect to a signal line assigned to itself among a plurality of signal lines even without a separate switch operation.

In general, in a large and complex system such as an electronic exchange, a cascade of a plurality of subordinate units performing the same operation as a concept of a module is performed to perform each specific function, and the number of subunits is a capacity, that is, an exchanger. For example, the number of subscriber boards varies depending on the number of subscribers, so the system does not provide signal lines directly to each slave unit, but allows each slave unit to share signal lines that combine the signal lines for each slave unit.

Referring to the accompanying drawings, a common signal line connection method according to the conventional method in each subordinate unit having such a cascade structure is as follows.

FIG. 1 is a diagram illustrating a connection relationship between a conventional slave unit and a signal line and a wiring structure, and illustrates a connection relationship between the microprocessor 10 and three slave units U1, 2, and 3.

The subunits U1 to U3 shown in FIG. 1 have the same structure. Looking at the detailed structure, four signal lines a, b, c, d (dependent unit) from the microprocessor 10 are shown. Data input terminals IC1 to IC4 to which the number of signal lines +1 is applied, the data output terminals OC1 to OC4 connected one-to-one with the data input terminals IC1 to IC4, and the data input terminals IC1 to IC4. ) And an internal signal receiving a common signal line shared by all gates in common among the data signal lines between the data output terminals OC1 to OC4 and the corresponding signal lines in the order adjacent to the microprocessor 10 to perform a predetermined function assigned thereto. A circuit section 20 and a switching section SW for connecting any signal line except for the common signal line among the signal lines to the internal circuit section 20 are provided.

The method of connecting the corresponding signal line among the signal lines connected to the microprocessor 10 in order to perform the function assigned by the subordinate unit composed of the cascade configured as described above will be described first. The explanation is as follows.

Among the signal lines a, b, c, and d, the first signal line a is a signal line necessary for the first slave unit U1, and the second signal line b is a signal line required for the second slave unit U2. The three signal lines (c) are necessary for the third subordinate unit (U3), and can be changed as many as the initial setting (unit existence position). Also, all subordinate units have the same structure in U1 to U3 attached to the subordinate unit. Since it has the same function, it is a symbol attached in order from the right side based on the microprocessor 10.

In addition, since the fourth signal line d of the predetermined signals applied through the signal lines a, b, c, and d connected to the microprocessor 10 is a signal line necessary for all of the subordinate units U1 to U3, the internal circuit part is provided. A signal line other than the fourth signal line d is connected to the first signal connection terminal A of 20, and the signal line and the internal circuit unit are adjusted by adjusting the switching unit SW according to the position of the unit. The second signal connection terminal B of 20 is connected.

Therefore, in order for the first slave unit U1 to perform a predetermined function, the fourth signal line d and the first signal line a must be connected to the internal circuit unit 20, and the second slave unit U2 has a predetermined function. Since the fourth signal line (d) and the second signal line (b) must be connected to the internal circuit unit 20 in order to perform the following, each time the position shift of the slave unit is added or a new slave unit is added Since the magnetic signal lines must be connected by operating the switch, the cost of the connection switch is increased and the trouble of the connection switch operation is generated.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram illustrating a connection relationship between a subordinate unit and a common signal line and a wiring structure according to the present invention. The microprocessor 10 outputs different specific signals through a predetermined number of output terminals, and the microprocessor 10 The signal output from the output terminal of the () through the predetermined number of signal lines (A, B, ..., N) is applied to only the signal input through the corresponding signal line to perform a predetermined function and the microprocessor 10 It consists of a certain number of subordinate units (UA, UB, ..., UM) that output all the signals that are output and authorized. The configuration and wiring structure inside the subordinate units (UA, UB, ..., UM) Looking at it as follows.

Input terminals IC1 to ICN used as connection terminals of a predetermined number of signal lines A to N for transmitting signals output from the microprocessor 10 are connected one-to-one with the input terminals IC1 to ICN. The output signal OC1 to OGN and the connection signal line between the N-th input terminal ICN and the N-th output terminal ONC of the input terminals are applied to the first data input terminal X, and the first input terminal IC1 of the input terminals is applied. ) Is connected to the second data input terminal (Y) and the M-th output terminal (OCM) is composed of an internal circuit section 30 to perform a predetermined function.

Referring to the magnetic signal line connection connection method according to the present invention in the cascade unit configured as described above is as follows.

First, the wiring structure between each of the subordinate units UA to UM and the microprocessor 10 will be described. A common signal line necessary for all of the subordinate units UA to UM from the Nth signal line A among the signal lines A to N will be described. The first signal line (A) to the M-th signal line (M) are set to the unique signal lines allocated to the units (UA to UM), respectively, and the output terminal of the microprocessor 10 and the first slave unit ( The micro terminal is connected to the M slave unit UM in such a manner that the input terminals of UA are connected one-to-one, and the output terminal of the first slave unit UA and the input terminal of the second slave unit UB are connected one-to-one. The processor 10 and the slave units UA to UM have a cascade structure by the signal lines A to N. FIG.

At this time, the number added to each subordinate unit UA to UM is assigned according to the position based on the microprocessor 10. The operations performed in each subordinate unit UA to UM are the same, but are assigned according to the position. The signal line is changed and thus the object of the operation to be performed is changed.

At this time, the wiring structure inside the subordinate unit, that is, the wiring structure between the input terminals IC1 to ICN and the output terminals OC1 to ONC is divided into three types. First, the input terminals IC1 to ICN are primarily connected. The signal applied to the N-th input terminal (ICN) is connected to be output from the N-th output terminal (OCN). Thereafter, a signal applied to the first input terminal IC1 of the input terminals IC1 to ICN is connected to be output from the Mth output terminal OCM. Finally, the signals applied from the second input terminal IC2 to the Mth input terminal ICM among the input terminals IC1 to ICN are sequentially one-to-one so that they can be output from the first output terminal OC1 through the L output terminal OCL. Please wire in correspondence.

Thereafter, the connection for signal transmission between the N-th input terminal ICN and the N-th output terminal ONC is connected to the first data input terminal X of the internal circuit unit 30, and the first input terminal IC1 and the M-th output terminal ( The connection for signal transmission between the OCMs is connected to the second data input terminal (Y) of the internal circuit unit (30).

When the internal wiring structure is as described above, as shown in FIG. 2, the first output signal A of the microprocessor 10 is connected to the internal circuit unit 30 of the first slave unit UA. And the N-th output signal are applied through the first and second data input terminals (X, Y), the internal circuit unit 30 can perform a predetermined function normally.

In addition, since the second slave unit UB receiving the output signal of the first slave unit UA has the same internal wiring structure as described above, the second circuit unit 30 of the internal slave unit UB in the second slave unit UB is formed. The Nth output signal of the first slave unit UA, that is, the Nth output signal N of the microprocessor 10 is applied to the first data input terminal X, and the Nth output signal N of the microprocessor 10 is applied to the second data input terminal Y. Since the first output signal of the first slave unit UA, that is, the second output signal B of the microprocessor 10 is applied, the internal circuit unit 30 in the second slave unit UB performs a predetermined function normally. It becomes executable.

By providing the internal wiring method in the cascade connected cascade according to the present invention to operate as described above, a predetermined number of slave units (UA to UM) can be connected to the signal line corresponding to them normally and the position between the units Even when moving or expanding the number of units, there is an effect of eliminating the trouble of manipulating the connection switch in the conventional subordinate unit and suppressing an increase in the cost of the connection switch.

In addition to the internal wiring method described in the above-described embodiment of the present invention, a wiring method that can achieve the same effect will be briefly described with reference to FIG. 3 below, and the connection between the input terminals IC1 to ICN and the output terminals OC1 to ONC is described below. As described above with reference to FIG. 2, the structure is divided into three types. First, a signal applied to the first input terminal IC1 of the input terminals IC1 to ICN is first applied to the first output terminal OC1. In order to output from) Thereafter, a signal applied to the Nth input terminal ICN among the input terminals IC1 to ICN is connected to be output from the second output terminal OC2. Lastly, the signals applied from the second input terminal IC2 to the Mth input terminal ICM among the input terminals IC1 to ICN are sequentially outputted from the third output terminal OC3 through the Nth output terminal OCN. Connect in a one-to-one correspondence.

Thereafter, the connection for signal transmission between the first input terminal IC1 and the first output terminal OC1 is connected to the first data input terminal X of the internal circuit unit 30, and the Nth input terminal ICN and the second output terminal ( The wiring for signal transmission between OC2 is connected to the second data input terminal Y of the internal circuit unit 30.

Although the wiring method having the above structure seems to be different from the wiring method described in FIG. 2, when the characteristics of the output signal of the microprocessor 10 are actually set, the common signal of the slave unit is output to the first output terminal. When the signal to be applied to the first slave unit is output to the Nth output terminal and the signal to be applied to the second slave unit is output to the Mth output terminal, the same effects as described above with reference to FIG. 2 may be obtained.
