The present invention relates to a back board for a network management system (hereinafter referred to as NMS) of a communication / video service integrated access system, and includes cable broadcasting (CAble TeleVision: hereinafter called CATV) and video on demand (Video On). Demand: It is easy to configure the hardware when replacing the board for the board configuration and maintenance of the communication / video service integrated access system, which is a large-capacity system requiring various services such as VOD) and home shopping. The present invention relates to a back board for an NMS of an integrated access system for communication / video services.

In general, the NMS back board of the integrated communication / video service connection system applies the NMS back board of the conventional video service connection system, but the NMS back board of the conventional video service connection system requires more services. It is inconvenient to use in the communication / video service integrated access system, and it is impossible to make various configurations to various boards, and it is impossible to configure the system board only by a defect of a specific slot.

1 is a block diagram of a distribution center main control processor hardware block (DMHK), which is a back board for an NMS of a conventional video service access system. FIG. 1 is a power supply for powering each board of a DMHK block. Matching data input through the board 11 and the MPS bus (VME (Versa Module Europe: 32-bit system standard bus under development by Motorola, hereinafter referred to as VME) is a SCSI bus. Computer System Interface: A generic term for the standard device for matching computer system auxiliary storage devices according to the International Organization for Standardization. The data input through the bus is matched and controlled, and the FIFO (First-In First-Out: Mass Storage Interface Board (MSIB) for controlling one that is waiting first (12) and a processor for matching data input through the MPS bus and matching and outputting data input through the Q-bus (modified RS232, multiple boards can be used in a round robin method). Processor Inter-Communication Control Board (hereinafter referred to as PICB) 13 and a maintenance communication matching circuit pack that outputs serial alarm signal collection commands through the MPS bus and receives serial alarm signals. Assembly (hereinafter referred to as IOIB) (14, 15) and a message communication control circuit pack (LAN) performing a LAN (Local Access and Network) interface by matching data input through the MPS bus. 16) and a higher level main processor processor that controls the exchange of messages between the boards in the DMHK block and the redundancy of the DMHK block. A main and duplication control board (hereinafter referred to as MDCB) 17 and a distribution main back board (hereinafter referred to as DMBB) 18 for realizing termination of the MPS bus and the Q-bus. .

DMHK of the above configuration collects alarms through each IOIB (14, 15), and stores the information collected by the control of the MDCB (17) through the MSIB (12), such as a hard disk and a compact disk, MCCB ( 16) interface with a maintenance communication matching hardware block (hereinafter referred to as MIHK) (II-1) (not shown) in the communication / video service integrated access system.

In the DMHK as described above, each board has magnetic slot recognition logic as shown in FIG. 2, which compares a value input to a jumper 21 in which a jump value of the magnetic slot is set, and a value set in the jumper 21. Comparator 22, the comparator 22 is a jump value (VA <23 .. 19>) of the input signal and the jump value (D <7 .. 0>) set to the jumper 21 is the same The board outputs a match signal (match *) to operate the board. Otherwise, it outputs a match signal (match *) to high so that the board does not operate.

As described above, each board of the DMHK has a fixed slot position on which the magnetic board is to be mounted. If the boards are not mounted at the predetermined slot positions, the DMHK does not operate. As shown in IOIBs 14 and 15 in FIG. If there are two or more boards performing the same function, each board must be secured with jumper pins and mounted on a board in the specified slot.If you want to operate IOIB1 (15), you must jump from IOIB0 (14) to IOIB1 (15). Each board configures the address mapping of the magnetic board upon board initialization after board mounting. For this purpose, each board enables the SR3 * signal of the magnetic board recognition logic to enable the magnetic board set in the jumper 21. When the jump value is read and the signal to be processed by the DMBB 18 and the board to process the signal are designated and transmitted to each board, each board jumps the signal input from the magnetic slot recognition logic inside the board. The value and the jump value set in the jumper 21 are compared to check whether the input signal is for the magnetic slot (see the magnetic slot recognition logic operation).

In the DMHK for NMS of the video service access system having the above-described configuration, since the board is designated by a jumper value, the arbiter board (where MSIB 12 corresponds to MSIB 12) in which the arbiter 31 arbitrates the data bus is present. As in Figure 3 it must be located in the first slot.

The present invention is to solve the above problems, to give a fixed specific address for each slot, to recognize each fixed fixed address of the magnetic slot to each board, even if the boards performing the same function in the board 0 Rather than having to operate board 1 by jumping to 1, each board is operated by a specific fixed address of each board, and the output BGOUT * signal of the arbiter board where the arbiter is present is connected to the BG3IN * terminal of the first slot. By connecting, the present invention provides a back board for NMS of a communication / video service integrated access system configured not to be restricted in the position of the mounting slot of the arbiter board.

When described in detail with reference to the drawings as follows.

The same parts (functions and names) as in the prior art have the same reference numerals.

Each of the boards has magnetic slot recognition logic, and the magnetic slot recognition logic includes a fixed specific address (VA <23..21>, AM <2 .....) included in the input signal, as shown in FIG. 0>) and a comparator 22 which compares a fixed specific address (PA <3 .. 1>, PAM <2 .. 0>) of the magnetic board recognized by each board, and the comparator 22 If the comparison result is the same, the match signal (match *) is output low so that the board operates. Otherwise, the match signal (match *) is output high so that the board does not operate.

In the above-described I / O block, the arbiter board in which the arbiter 31 exists (corresponding to the NMCB 41) corresponds to the output signal SR3 * of the arbiter board and the BG3IN * terminal of the first slot as shown in FIG.
