BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0013]
FIG. 1 is a circuit block diagram showing a first embodiment of the control system according to the present invention. The control system monitors N line cards 1, N SW (switch) boards 2 of the same number as the line cards 1, and package types of the SW boards 2, and monitors SW (switch) on the SW boards 2. It is composed of a control circuit 4 for controlling the control unit 22 and a BWB (back wire board) 3 for connecting each unit.
[0014]
The line card 1 has a function of terminating the main signal 101 via each subscriber and the SW board 2, and the SW board 2 has a function that the line card 1 does not have. Here, the SW panel 2 is provided with a SW 22 for redundancy switching for convenience, and several types exist for each desired function. In order to specify this type, it is assumed that each SW board 2 has a unique package type. In this case, the control circuit 4 needs to accurately determine the position where the package is mounted and the type, and control the SW 22 in the SW panel 2 for each type.
[0015]
Therefore, the control circuit 4 transmits the address signal 103 to the SW board 2. The SW board 2 obtains mounting position information 102 that differs for each mounting position from the BWB 3 and compares the address signal 103 from the control circuit 4 with the package type transmitting circuit 21. When the mounting position signal 102 and the address signal 103 match, the package type information 104 is transmitted to the control circuit 4 as parallel data. If the mounting position signal 102 and the address signal 103 do not match, a high impedance state is set so as not to collide with the output from another SW board 2. The control circuit 4 controls the SW 22 by outputting a SW control signal 105 to each SW board 2 according to the obtained package type.
[0016]
Next, the operation of the control system having the above configuration will be described in detail with reference to FIGS. In the following description, the number N of the line cards 1 is set to 7 and the type of the SW board 2 is set to 3 for convenience.
[0017]
If N = 7, the mounting position information of the BWB 3 can be represented by 3 bits, and information “000” to “110” is assigned to each SW board 2 from the mounting position. “111 (= ZZZ)” should not be assigned when the control circuit 4 is not mounted, in order to prevent abnormal operation. Also, two bits are prepared for the package type and assigned to “01”, “10”, and “00”, and “11 (= ZZ)” indicates an unmounted state.
[0018]
The control circuit 4 outputs an address signal 103 of the SW board 2 whose package type is to be collected to all the SW boards 2. For example, when mounting position information “000” is input from the BWB 3 and package type information of the SW board 2 whose package type is “00” is collected, first, the control circuit 4 sends the address signal 103 "000" is output.
[0019]
The package type transmission circuit 21 in each SW 2 compares the address signal “000” with the mounting position information 3 bits input from the BWB 3 by the comparison circuit 201, and outputs the output / output of the 3-state buffer 203 based on the control signal 202. Perform stop control. If the mounting position information is "000" and matches the address signal, the package type information 104 "00" is output from the three-state buffer 203. If the mounting position information is other than "000", the three-state buffer 203 is output. In the high impedance state does not hinder the operation of the other SW boards 2. When the corresponding SW board 2 is not mounted, the package type is recognized by the control circuit 4 as “11 (= ZZ)”.
[0020]
According to these procedures, the control circuit 4 periodically collects the package type information 104 and controls the SW 22 in the SW panel 2 by the SW control signal 105 corresponding to the function / performance.
[0021]
As a second embodiment of the control system according to the present invention, the basic configuration is as described above, but a case where the transmission method of the package type is further devised will be described.
[0022]
As shown in FIG. 3, this control system converts the package type information 104 transmitted as parallel data into serial data by the control clock 106 by the P / S converter 204, thereby providing a physical The wiring is reduced.
[0023]
Accordingly, the timing chart of the operation of the package type transmitting circuit 21 using the P / S converter 204 is as shown in FIG. That is, the control circuit 4 outputs an address signal 103 of the SW board 2 whose package type is to be collected to all the SW boards 2, and the corresponding SW board 2 is serialized by the package type transmitting circuit 21 in the SW board 2. The package type information 104 of the data is generated and transmitted to the control circuit 4 via the BWB 3. The control circuit 4 controls the SW 22 by outputting a SW control signal 105 to each SW board 2 based on the received package type information 104.
[0024]
