Description

  The present invention relates to an ATM device and a device identification code setting method, and in particular, in a network system in which a plurality of ATM devices are hierarchically arranged and connected, each ATM device is monitored, controlled, and managed from a monitoring control terminal. The present invention relates to a technique for automatically assigning and setting a device identification code used for identifying and specifying each ATM device when appropriately operating and operating each ATM device.

  FIG. 5 shows a configuration example of a network system in which a plurality of ATM devices are hierarchically arranged. In the figure, 1 is a supervisory control terminal (OPS) for monitoring and controlling each ATM device, 10 is a first-tier ATM device, 20, 21 are second-tier ATM devices, and 30, 31 are first-tier ATM devices. It is a three-tier ATM device.

  When each ATM device 10, 20, 21, 30, 31 is monitored and controlled by the supervisory control terminal (OPS) 1, conventionally, each ATM device can be identified separately from other devices. A device identification code (hereinafter referred to as a device ID) is set for the ATM devices 10, 20, 21, 30, and 31. The conventional device ID is set by the user or maintenance person by selecting and setting the device ID for each ATM device 10, 20, 21, 30, 31, or by setting each ATM device 10, 20, 21. , 30, 31 and the like, the device ID is determined and set based on the machine number assigned at the time of manufacture.

Japanese Patent Laid-Open No. 10-4373

  As described above, in a conventional method in which a user or a maintenance person appropriately determines and sets a device ID for each ATM device, the determined device ID is assigned to each ATM device from the monitoring control terminal (OPS) 1. It is necessary to set one by one by manual input operation. As the number of ATM devices monitored and controlled by the supervisory control terminal (OPS) 1 increases, more time and effort are required. Setting errors are likely to occur because of input.

  Any of the ATM devices 10, 20, 21, 30, and 31 that perform monitoring control from the monitoring control terminal (OPS) 1 by sharing a common communication line in in-channel communication, due to a setting error. If the same device ID as the device ID is set, monitoring control cannot be performed normally.

  In addition, as a method for setting the device ID, there is a method of assigning a unique device ID by setting each device ID with a dip switch or the like when each ATM device is installed. However, the setting value of the dip switch is set incorrectly. If this happens, the supervisory control terminal (OPS) 1 cannot communicate with the ATM device, and a maintenance person goes to the installation location of the ATM device to check the setting value of the DIP switch. Must be set again.

  According to the present invention, it is possible to automatically set a device ID to each ATM device while avoiding duplication of setting values of the device ID, and it is easy to grasp the connection form of each ATM device from the device identification code for management. An object of the present invention is to provide an ATM device and a device identification code setting method capable of generating and assigning a device identification code.

  The ATM device according to the present invention is (1) a hierarchically arranged ATM device that constitutes a network system, and for each ATM device in the immediately lower hierarchy, represents a hierarchy and has different hierarchy identification information for each ATM device. A hierarchical identification information setting unit that is assigned and set as an identification code, and for each ATM device in the immediately lower hierarchy, a virtual path identifier and a virtual channel identifier for in-channel communication for monitoring control are further added to the hierarchical identification information Virtual circuit identification information setting means for giving and setting.

  (2) Virtual line identification information setting in which a slot number indicating a slot position of a panel in which an interface panel to which each ATM device in the immediately lower layer is connected is accommodated is further added and set as the device identification code Means are provided.

  Also, (3) device identification code setting that sets the device identification code including the layer identification information, virtual path identifier, and virtual channel identifier assigned by the higher layer ATM device, and holds the history of the set device identification code A history information holding unit is provided.

  The device identification code setting method is (4) a device identification code setting method in which device identification codes are set for ATM devices that are arranged hierarchically and constitute a network system.

  (5) In the virtual circuit identification information setting process, a slot number indicating a slot position of a panel in which an interface panel to which each ATM device in the immediately lower layer is connected is further assigned as the device identification code. Including a setting process.

  (6) Device identification code setting that sets the device identification code including the layer identification information, the virtual path identifier, and the virtual channel identifier assigned by the higher layer ATM device, and holds the history of the set device identification code It includes a history information holding process.

  According to the present invention, each ATM device arranged hierarchically assigns a device ID including hierarchical identification information and virtual circuit identification information to each ATM device directly below, so that the device ID of the maintenance person etc. Setting time is saved, duplication of setting values of device IDs can be avoided, and communication failure due to erroneous setting of device IDs can be prevented.

  Further, for management, the hierarchical position information and the virtual circuit identification information can be obtained from the device ID, and it becomes easy to grasp the connection form of the ATM device. Also, by holding the device ID setting history, it is possible to easily grasp the past connection form based on the device ID setting history, and effectively use it for network system operation management, failure investigation, etc. It becomes possible to do.

  In the present invention, the maintenance control terminal (OPS) 1 does not set the device ID by manual input operation to each ATM device 10, 20, 21, 30, 31 from the monitoring control terminal (OPS) 1. 1) Each ATM device 10, 20, 21, 30, 31 is automatically assigned and set in accordance with its connection form by only the command command for setting device ID assignment.

  FIG. 1 shows a format of a device ID given by the present invention. As shown in (a) in the figure, the device ID is represented by 6 bytes, and the first 3 bytes (first to third bytes) of the device ID are the hierarchy of the ATM device (as viewed from the monitoring control terminal (OPS) 1). Information indicating in which column the connection device is located) and identification information for each hierarchy (hereinafter referred to as hierarchy ID).

  The next byte (fourth byte) after the byte representing the layer ID represents the slot number in which the interface circuit board (hereinafter referred to as IF board) to which the ATM device directly below is mounted, and the next 1 byte. (5th byte) represents a virtual path identifier (VPI: Virtual Path Identifier, hereinafter referred to as VPI) value of a line connected to the IF board of the directly connected ATM device, and the next 1 byte ( The sixth byte) represents a virtual channel identifier (VCI) value of a line connected to the IF board of the directly connected ATM device.

  The example of the device ID shown in FIG. 1A is located in the second layer when viewed from the supervisory control terminal (OPS) 1, and the IF board of the higher connection destination ATM device is mounted in the slot 1, This indicates that the ATM device is connected to the VPI value and the VCI value through lines of VPI = 32 (0x20) and VCI = 255 (0xFF), respectively.

  As a hierarchy ID assigned to the first to third bytes of the device ID format, as shown in FIG. 1B, a 4-bit identification code (values “1” to “15” can be set) in each hierarchy. 15 ATM devices can be identified by one layer ID in one layer. Since one byte is 8 bits, the layer ID can be set up to the first to sixth layers with the first to third bytes.

  The setting of the hierarchy ID will be described below. For setting the device ID to each ATM device, first, the device ID “100000000 (hex)” is uniformly assigned to the first ATM device 10 connected immediately below the supervisory control terminal (OPS) 1. Set. From the ATM device 10 immediately below the supervisory control terminal (OPS) 1, “1” is entered in the portion representing the second layer of the layer ID and the device ID “110000000000000 (hex)” is set in the second layer device. Then, using the device ID setting command, the virtual board information of the slot number, VPI value, and VCI value of the IF panel as described above is used as the lower 3 bytes of the device ID for the device of ID “110000000000000”. Set.

  In order to perform monitoring control by in-channel communication for each ATM device, the slot number of the IF panel to which each ATM device is connected, the VPI value and the VCI value of the connection line as the in-channel communication line connection information Is determined and set in advance by a maintenance person. By using the set value as it is and setting it in the lower 3 bytes of the device ID, a unique device ID can be automatically determined and set for each ATM device.

  When a plurality of ATM devices are connected to the second layer, the second layer portion of the device ID (see FIG. 1B) is sequentially incremented by +1 in the ATM device 10 of the first layer, and the second It is set in each ATM device 20, 21 in the hierarchy. The ATM devices 30 and 31 in the third hierarchy inherit the portions of the layer IDs of the first layer and the second layer from the ATM devices 20 and 21 in the upper second layer, and the portion of the layer ID in the third layer The ATM devices 20 and 21 in the second hierarchy are sequentially incremented by +1 and set in the ATM devices 30 and 31 in the third hierarchy.

  For example, when the hierarchy ID of the ATM device 20 in the second hierarchy is “120,000...”, The hierarchy ID of the first ATM device 30 in the third hierarchy is “121000. The second hierarchy ID of the third hierarchy is “122000...”.

  FIG. 2 shows an apparatus ID automatic assignment sequence. This figure shows an example of a procedure for registering a device ID in the ATM device in the second layer. In this procedure, first, a host device connection information registration command is transmitted from the supervisory control terminal (OPS) 1 to the ATM device 10 (2-1). When the ATM device 10 directly under the supervisory control terminal (OPS) 1 receives the command and “100000000000000” is registered as the device ID of the own device, polling for confirming the startup state from the ATM device “100000000000000”. A command (POL) is transmitted to the ATM device 20 in the second hierarchy (2-2).

  If the device ID is not set, the second layer ATM device 20 returns startup status response information indicating that the device ID is not set as a polling command (POL) response (2-3). Since the ATM device “100000000000000” in the first layer recognizes that its own device is the first layer, it can recognize that the layer of the ATM device 20 immediately below is the second layer, and the ATM device directly below 20, the device ID “110000000000000” (operating the lower 4 bits of the first byte of the layer ID (representing the second layer)) is set by the device ID layer setting command (2-4).

  Upon receiving the device ID “110000000000000”, the second layer ATM device 20 returns a response to the first layer ATM device 10 (2-5), and the first layer ATM device 10 sets the device ID. To set the lower 3 byte device ID for the second layer ATM device 20 (2-6), and the second layer ATM device 20 receives the lower 3 byte device ID, for example, The device ID “1100010001211” is set, and a response is returned to the ATM device 10 in the first layer (2-7).

  When an ATM device 21 other than the device ID “1100010001211” is connected to the second layer, a supervisory control terminal (OPS) 1 sends a host device connection information registration command to the ATM device 10 (2-8), The ATM device 10 receives the command and transmits a polling command (POL) for confirming the startup state to the ATM device 21 in the second layer (2-9).

  If the device ID is not set, the second-tier ATM device 21 returns startup state response information indicating that the device ID is not set as a polling command (POL) response (2-10). The ATM device “100000000000000” in the first layer recognizes that the layer of the ATM device 21 directly below is the second layer, and increments the second layer portion of the device ID by +1 with respect to the ATM device 21 directly below, The device ID “120000000000000” (operating the lower 4 bits (representing the second layer) of the first byte of the layer ID) is set by the device ID layer setting command (2-11).

  Upon receiving the device ID “12000000000000”, the second layer ATM device 21 returns a response to the first layer ATM device 10 (2-12), and the first layer ATM device 10 sets the device ID. The device ID of the lower 3 bytes is set for the second layer ATM device 20 by the command (2-13), and the ATM device 21 of the second layer receives the device ID of the lower 3 bytes, for example, the device An ID “120000022021” is set, and a response is returned to the ATM device 10 in the first layer (2-14). Thereafter, the device ID is set for each ATM device in the third layer and lower by the same method.

  The device ID is held as a device ID setting history in a non-volatile memory mounted on each ATM device. As the device ID setting history, for example, the set date and setting device ID are recorded for about 50 device IDs. An example of recording of device ID setting history information is shown in FIG. As a result, it is possible to easily specify the connection form such as which host device the ATM device has been connected to in the past, and which VP path and VC path it has been connected to. It can be used for operations management and trouble investigation.

  FIG. 4 shows an embodiment of a network system to which the present invention is applied. As shown in FIG. 2A, the supervisory control terminal (OPS) 1 and the first layer ATM apparatus 10 are one, and the supervisory control terminal (OPS) 1 and the ATM apparatus 10 are connected by a LAN line. It can be set as the structure to do. Communication for operation management with each ATM device 20, 21, 30, 31 under the ATM device 10 in the first layer is performed by in-channel communication using an ATM line for service provision, and between each ATM device. In this connection, it is assumed that one lower ATM device is connected to the IF panel of one panel of the upper ATM device.

  On the display screen of the supervisory control terminal (OPS) 1, a graphical interface capable of inputting and setting the IF board mounting position (slot number) and connection path (VPI, VCI) of the upper ATM device to which the lower ATM device is connected. It is assumed that a user interface is incorporated. Further, the history of the connection form of each ATM device can be read on the display screen of the supervisory control terminal (OPS) 1.
