Description

  The present invention relates to a media inventory management technique in a communication station used for commercial purposes, and in particular, a media inventory management device and a media inventory management method for managing a laid medium, and a processing program for performing a media inventory management process. The present invention also relates to a computer-readable recording medium on which the program is recorded.

Prior to the prior art, the features of media inventory management in a communication station targeted by the present invention will be described.
(About service characteristics of communication media in communication stations)
FIG. 7 is an explanatory diagram showing the types of communication services.
In a communication station, there are two patterns mainly as service types.
One of the service types is a service called the direct collection method shown in the upper part of FIG. 7, and a one-to-one relationship is always maintained from the start point (customer side) to the end point (on-site device side). It always takes the form that there is one end point. In this case, a medium such as a cord / terminal that is not always occupied by another subscriber is selected as the communication medium in the communication station.
Next, as one of the service types, there is a multi-branch service shown in the lower part of FIG. 7, and an n-to-1 relationship is established from the start point (customer side) to the end point (in-house device side). This is a form in which a single fiber is shared by a plurality of subscribers to a branching device (hereinafter referred to as a branching device) in the middle of the optical signal emitted from the device that is the end point. After the branch device, the service is provided by a plurality of core wires / terminals. As a feature of this service, in the case of selecting the first subscriber, as with the direct acquisition service, the communication medium in the communication station is always a medium such as an empty core / terminal that is not occupied by other subscribers. It is said.
However, in the case of selection with the same service of the second subscriber, all the core wires / terminals from the device to the branch device are occupied (connected), and there is an empty terminal on the output side in the branch device. Opening is possible.

(Necessity of inventory management)
Disbursement of inventory in a communication station refers to an act of selecting a wiring between a terminal of an outside node connecting a service user and the communication station and a communication device (inside node) that actually provides a service. In this case, the inventory equipment in the communication station refers to terminals in the wiring or node, and in order to open a service, the stock is paid out by efficiently selecting and connecting those inventory equipment. Is called. At that time, it is understood that there is a need for inventory management for the following two reasons in performing the selection process.
First, in order to carry out facility selection, in order to search for the route of any point-to-point terminal (connection between cable and cable rack or in-house device) in the communication medium group in the communication station, the route It is necessary to search for the core wire, the adapter terminal, and the multi-branch / wavelength multiplexing adapter terminal. Also, in order to select the route of any point-to-point terminal in the communication media group in the communication station, service provision conditions, equipment conditions, usage status and status of communication medium components, loss (connection point) / connection A route that takes into account the number of work points must be selected. Here, the service provision conditions are the communication method and the number of optical branches, the communication wavelength, the test wavelength, the connector reflection characteristics (optical characteristics), the optical transmission mode, the number of necessary media, the planned use date / the planned abolition date.

  The equipment conditions are the shape of the connector and adapter terminal attached to the cable core, and connection is not possible unless the shape of both is the same. The usage status of the components of the communication medium means that when the service is provided, the free equipment of each communication medium (equipment that is not used for the service) is used. This is the usage situation here. The status of the components of the communication medium is used to determine whether each communication medium can be used for service. In that state, there is “Reserved with good equipment (in use)”, and the communication medium at the time of service provision When selecting a service, select “Equipment with good equipment” and change it to “Reserved with good equipment (empty)”, then change to “In use with good equipment” after the start of service provision. In addition, when selecting a service when it is abolished, “in use with good equipment” is changed to “reserved with good equipment (in use)”, and after service is abolished, it is changed to “empty equipment with good equipment”. When the communication medium group configures the path of the point-to-point terminals, the communication media must be connected with a connector or the like. Therefore, communication loss increases as the number of connection points between two points increases, and connection work occurs at the connection points. Therefore, the quality of the connection points decreases as the number of connection points decreases. Good and workable.

Therefore, when selecting equipment in a communication station, let's select a route that takes into consideration the service provision conditions, equipment conditions, usage status and status of communication medium components, and loss (connection points) / number of connection work points. To do so, there are an infinite number of core route patterns. In particular, with the recent technological advances, the service forms (direct acquisition, multi-branch / wavelength multiplexing, etc.) have become more complicated, and the selection policy has changed further for the first and second subscribers, covering all conditions. Enormous operation is required to select equipment. Therefore, as a special feature in implementing selection within a communication station, in addition to a communication medium selection method for selecting a route between any two point-to-point terminals, a selection that takes into account multi-branch services and wavelength multiplexing services is efficient. It means that it needs to be implemented.
In this way, in order to carry out the selection process between any two points, it is necessary to carry out many processes to check the inventory equipment status of the route each time it is selected, and to select the optimal selection route. The amount of processing increases in proportion to the number of selections. Moreover, since the usage state of the in-house wiring facility changes every time it is selected, it takes a lot of time to manage the inventory status in advance by the worker and grasp the inventory amount on the route.

Secondly, if the current (service is being provided) equipment is changed to non-current equipment due to the abolition of service (suspension of service), the next demand will be applied rather than opening all the connection points in the route. In preparation for this, it is possible to improve operational efficiency by opening certain connection points. Also, rather than leaving all wires and terminals unconnected, it is necessary to keep specific terminals and wires connected, so that construction can be carried out efficiently when service opening work actually occurs. Is possible.
Thus, in order to quickly select equipment in the communication station, opening work that requires opening work should not be carried out because of problems in speeding up the work, but simply connecting It is required to open the facility using facilities that can be used simply, and it is necessary to grasp the amount of such facilities.

(Characteristics of media inventory management in the communication station)
8 and 9 are explanatory diagrams showing the features (1) and (2) of the inventory quantity in the in-house wiring facility.
The following are the features of media inventory management in the communication station.
First, non-working equipment cannot always be recognized as inventory. The equipment in the communication station has several optical cable connectors already connected to improve the efficiency of the connection work or when certain demand is expected from the outside node. Construction efficiency can be improved by connecting to the node in advance. For example, as shown in FIG. 8, it is assumed that there are two outside nodes ((1) (2)) and one inside node and one relay node.
Assume that the cable connecting the outside node (1) and the relay node is a cable 1, and two core wires among the all core wires on the relay node side are already connected to the terminals in the relay node. Next, it is assumed that the cable connecting the outside node (2) and the relay node is the cable 2, and one core wire among all the core wires is already connected to the terminal in the relay node. On the other hand, the cable connecting the relay node and the inside node is a cable 3, of which three core wires are already connected at both ends, and the cable 1 or the cable 2 core is on the back of the terminal connected to the relay node side. A line is a connected state, and the terminals connected to the inside node are all the empty terminals held by the inside node.

In such a facility form, the service has not yet been opened, and all the facilities are nominally inactive. For this reason, all existing facilities should be used as inventory facilities, and it can be seen that the inventory core dose of the cable 3 is a three-core segment. However, when the demand connecting the outside node (2) and the inside node is actually generated, the number of demands that can be opened is only one line.
This occurs because two of the inventory cores existing in the cable 3 are already connected to the outside node (1). This means that even if the cable has three inventory cores in the cable 3 and two inventory cores in the cable 2, the demand for the maximum two cores will be opened depending on the connection status. It means that it cannot be judged possible.
In this way, it is difficult to show an accurate inventory amount only by management of current / non-current, and workers always need to manage the inventory with the connection status taken into account. There is a special feature.

The second feature is that it takes time to grasp the inventory quantity when multi-stage branch devices are installed.
As shown in FIG. 9, in the case of a service using a multi-branch method, a case where branch devices are installed in a plurality of relay nodes is also assumed. In such a case, the stock quantity in the section of the inside node (1) and the outside node (1) cannot be determined only by the stock quantity of the cable 1 and the cable 4. After confirming whether or not the branch device that can provide the corresponding multi-branch system service is installed in another relay node, grasp the amount of free equipment from the output side of the branch device, and then the cable on the lower side There is a feature that it is necessary to grasp the inventory quantity, and the inventory quantity cannot be defined as an open inventory facility depending on the connection state as described above.

(Prior art 1)
By storing the information on the accommodation location at the end of the unused wiring by associating the wiring identification code and the accommodation location identification code with each other, it is possible to manage unused core wires within a certain node. Inventory grasp was possible. However, in reality, since only the inventory of a specific section can be grasped, the wide-area usage situation at the outside end point (termination frame) and the inside end point (inside device) was not managed. . This means that even if it is an unused core in the specified section, it is a connected core in the next section, so there may be no unused core in terms of inventory. ing. For this reason, the inventory amount of the in-house wiring has not been grasped in a wide area, and the specific management of the true working cord / non-working cord has not been performed. Therefore, the judgment based on the inventory reduction is only for the case where the absolute amount of unused equipment for each section exceeds the manually set threshold value, and it is difficult to accurately determine the inventory quantity in a wide area and on the time axis. Therefore, the usage rate has not been determined accurately, and in order to ascertain the number of stocks required for medium- to long-term demand forecasting, it is necessary to manually check the data. It was necessary.
As a definition of terms, a route refers to a route connecting a specific outside node and a certain inside node. Moreover, a section means between a specific node.

(Prior art 2)
As for one method of wiring management in a communication station, for example, “Network management support device and network management method and storage medium storing program used therefor” described in Japanese Patent Laid-Open No. 10-224351 (see Patent Document 1). is there. This proposes a method for realizing configuration management of a corresponding network by acquiring a message on the network.
The above system is characterized by realizing network configuration management by acquiring transmission path information between nodes from a telegram, and by applying these conditions to wiring management in a communication station. Since the wiring configuration information is known, it can be applied, but it does not take into account that it cannot be recognized as inventory simply by acquiring configuration management information including working and non-working on the network. That is, in the communication station, depending on the connection state, it can be considered that the stock is only between the route of a specific outside node and the inside node. For this reason, the existing technology aims to manage only the configuration of the transmission path, and therefore it has abundant stock in a specific route, but it does not take into account that it is not in stock for other routes.

(Prior art 3)
As one method of wiring management in a communication station, for example, there is a “network management method and network management system” described in Japanese Patent Laid-Open No. 2000-209201 (see Patent Document 2). This is a technique for displaying network logical information or physical configuration information in a view, and realizing network configuration management that enables efficient management even if the network is through different multi-vendor devices. .
The above system is characterized in that it displays physical network and logical network information as a view and realizes network configuration management for managing each service, and these conditions are applied to wiring management in a communication station. Since the configuration information of the wiring can be understood from the above, it can be applied, but it does not take into account that it cannot be recognized as inventory only by acquiring logical or physical configuration management information on the network. That is, in the communication station, depending on the connection state, it can be considered that the inventory can be opened only between a specific outside node and a route of the inside node. Therefore, the existing technology does not take into account the feature that the transmission path is connected in advance.

  In addition, the above system does not take into account the inventory management method in the multi-branch method. As one of the communication services, there is a service characterized by branching a single core wire into a plurality by using a branch device or the like, such as a multi-branch method, and the section from the communication device to the branch device is Although it is an in-use facility, it has the feature that it becomes a stock facility from the unused terminal on the output side of the branch equipment. Therefore, from the start point to a specific node is a facility (transmission path) that is currently in use, but branches from the specific node onward, and there are working lines and non-working lines on the branched output side. However, it is not added.

(Prior art 4)
As a method of wiring management in a communication station, for example, there is “Wiring management system and wiring management method” described in Japanese Patent Laid-Open No. 2000-69106 (see Patent Document 3). This is a technique that makes it possible to manage physical information of a network by giving identification information to an optical fiber or the like that is a passive component.
The system is intended to realize electronic information management by assigning identification information to equipment (such as an optical fiber node) reaching the communication station and converting the equipment information into a DB. By applying these conditions and methods to the wiring management in the communication station, the configuration information and connection information of the wiring can be understood, so it can be applied, but if the operator only acquires the physical connection information, It is not taken into account that the operation of counting inventory information is enormous. Therefore, with existing technology, in order to manage inventory information between routes (between outside nodes and inside nodes), connection information for each section is acquired, and how much demand is required for each service based on that information. It is necessary for the operator to manually manage whether or not the information can be opened, and in order to manage the information in real time, a very large amount of operation is required. Thus, the point of dynamically managing inventory information in real time without being aware of the huge amount of equipment and multiple services is not taken into consideration.

JP-A-10-224351 JP 2000-209201 A JP 2000-69106 A

As described above, in order to always carry out optimal equipment selection, it is necessary to carry out a process for searching for an enormous amount of inventory every time. Moreover, since the use state of the equipment changes each time the equipment is selected, the amount of work for grasping the stock quantity in advance is enormous and takes a lot of time. Furthermore, the definition of inventory in the communication station needs to be defined in consideration of the connection state of equipment as well as the interpretation of simply working / non-working. In addition, in the case of a facility configuration in which multi-branch equipment is installed across multiple stages, not only the equipment status on the output side of the branch equipment installed at each node, but also the lower (outside node) side where the connection occurs It is necessary to calculate the amount of inventory after confirming the equipment status. Inventory management within a communications station with such special factors often relies on manual processing by workers, and in order to quickly replenish the inventory by adjusting the equipment inventory paid out by daily demand It needed a lot of operation.
As mentioned above, in order to carry out optimal equipment selection, it is necessary to grasp the inventory status of equipment each time and to carry out the selection, and the fact that it took an excessive amount of time in advance. From the fact that it takes a lot of operation to grasp, it can be seen that it took a lot of time and operation to grasp the inventory status.

(the purpose)

This ensures that the selection can be successful without having to carry out a huge selection process on the route. For, quick to display and notification to the operator.

Relay node determination step 402, service type determination step 403 for determining a service for aggregating the stock amount of a specific service, and a specific service in a route connecting the outside node and the inside node to a relay node The amount of successful selection in the above is used as the stock amount, and the stock amount summation step 404 for summing up and the stock amount saving step 405 for storing and accumulating the specified stock amount are included.

FIG. 5.1 is a process flow chart of inventory quantity aggregation (direct acquisition method) showing an embodiment of the present invention.
As a procedure for inventory quantity summarization in the direct collection method, the connected terminal in the inside node that acquires the connected terminal (1, 2, 3,... I) in the inside node when summing up the inventory quantity. If the acquisition step 501 and the acquired terminal are not present, the in-house cable cores (1, 2, 3,... J that are laid toward the inside node that can be connected to the inside node terminal are connected. ) To search for a free core connector that can be connected to the inside node terminal to search for, and if the above free core cannot be obtained, step 504 to end the processing, If a free core connector in the in-house cable that can be laid to the connected inner terminal or the inner node can be acquired, step 503 arbitrarily acquires the outer node terminal to search for the next outer node terminal; If all the terminals mounted on the outside node are connected, and no terminal can be acquired in the corresponding outside node, step 504 for ending the process of having no space, and the outside node If there is a vacant terminal that can be acquired within the designated service, the provisional selection is carried out for the designated service type that is to be provisionally selected in the next designated service. The connected terminal in the next inward node is acquired via the successful route definition step 506 for defining the selected route as the stock and the step 508 for searching for the next undefined stock candidate not defined as the stock. If the temporary selection fails in step 501, the number of selections (S) is counted (step 507), and all the connected terminals in all the inside nodes are free. When the number of wire connectors is provisionally selected (S = i + j), the provisional selection is finished, the inventory information storage step 509 for storing the inventory information, and the terminal or the empty core wire connector to be temporarily selected still exist ( i + j> S) includes a step 508 for searching for the next candidate again.

FIG. 5.2 is a processing flowchart of inventory totalization (multi-branch method) showing an embodiment of the present invention.
The procedure for total inventory in the multi-branch method is to count the number of branch devices required in the corresponding service when totaling inventory, and the number of required output terminals (8 branches In this case, step 600 for obtaining the number of branch devices (K) in the route for obtaining the terminal (8) and the number of output ports (h) of the corresponding branch device, and the connected terminals (1, 2 at the inner node) ,...) I) is acquired and the connected terminal acquisition step 601 in the inner node is acquired, and if there is no acquired terminal, it is laid toward the inner node that can be connected to the inner node terminal. Step 602 for acquiring an empty core connector that can be connected to a local node terminal that searches for a local cable core, and if the above-mentioned empty core cannot be acquired, the process ends. Step 604 and, if a free core connector in the in-house cable that can be laid to the inside node is connected to the connected terminal in the inside node, the outside node terminal that searches the outside node terminal next If there are connections for the number of terminals mounted on the outside node, and no terminal can be obtained in the corresponding outside node, there is no space. A process end step 604.

  Furthermore, if there is a vacant terminal that can be acquired in the outside node, the provisional selection is executed in step 605 for the designated service type for which provisional selection is performed in the designated service and the provisional selection is successful. If so, step 606 for defining a successful selected route as inventory, step 606 for defining a successful route as inventory, and step 610 for adding a provisionally selected execution flag to the output terminal in the branch device selected in the provisional selection; A step 611 for calculating the provisionally selected execution flag (P) in the branch device by counting the provisionally selected execution flags existing in the branch device, and the P value is the number of all the output terminals of the branch device. If (P = h), step 601 for obtaining a connected terminal in the next inner node and if there are still output terminals to be temporarily selected (P <h) Step 605 in which temporary selection is performed at terminals in the local node and remote node, and if the temporary selection fails, the number of selections (S) is counted (step 607), and all branch devices When the number of output terminals (K × h = S) is selected, the provisional selection is finished, the inventory information storage step 609 for storing the inventory information, and the output terminals to be temporarily selected still exist (K × h> S) includes a step of searching for the next candidate again.

FIG. 6 is a process flowchart for defining a successful route as an inventory according to an embodiment of the present invention.

In the case where the inside node terminal is not connected based on the above confirmation procedure, the step 702 for saving the inside node unconnected route and the inside node terminal are already connected. In some cases, there are a step 703 for saving as a route connected to the inside node, and a stock definition completion step 704 for finally completing the stock definition.

(Inventory management procedure)
FIG. 10 is an explanatory diagram showing the inventory counting method in the present invention.
(i) Setting of aggregation target table In order to set a route and a service for managing inventory, it is necessary to register the aggregation target table according to the following procedure. The upper part of FIG. 10 is the inventory aggregation method, and the lower part is the aggregation object table registered thereby.
For a unique route name, a node that is an outside node is selected, and a node that is an inside node for this is selected. Next, when it is necessary to insert a relay node existing between both nodes, it is turned on. Next, a service type that performs temporary selection in the set route is input. Mainly, it is possible to register for each service type such as direct acquisition system or multi-branch system.
At this time, if the inventory quantity between the outside node and the inside node is to be managed in a broad sense, the inventory is broadly defined by introducing only the outside node and the inside node without registering the relay node. Can be managed. Conversely, the more detailed the relay nodes are set, the narrower the inventory amount to be managed, but the more targeted management becomes possible.
In FIG. 10, for the route (1), the termination rack (1) as the outside node, the device (1) as the inside node, the intermediate rack (1) as the intermediate node 1, and the service type as the outside node. The direct acquisition system is selected and registered in the table. For route (2), termination rack (1) is used as the outside node, equipment (1) is used as the inside node, intermediate rack (2) is used as intermediate node 1, and multi-branch system is used as the service type. Is selected and registered in the table.

FIG. 11 is an explanatory diagram of a counting method (in the case of direct acquisition service) in the present invention.
(ii) Inventory equipment count (in the case of direct acquisition method)
As a method of counting the amount of inventory equipment in the case of direct acquisition service, provisional selection is made between any terminal in the outside node and the connected or unconnected terminal of the in-house cable laid on the inside node side. It counts by carrying out. Temporary selection is performed at points at both ends, the amount of equipment that can be opened is counted, and the calculated equipment amount can be counted as the inventory equipment amount in the target route.
In FIG. 11, the number of successful routes connected to the inside node is three and the number of successful routes not connected to the inside node is one by performing temporary selection with respect to the current state of the direct acquisition method in the upper stage. Yes, when the successful routes (1) to (4) are actually completed by using the cable 1 and the cable 2 by the inventory totaling table in which they are registered, the figure in the lower stage is obtained. In the intermediate rack (1), terminals of numbers 2, 3, 1, and 5 are used.

FIG. 12 is an explanatory diagram of a counting method (in the case of a multi-branch service) in the present invention.
(iii) Inventory equipment count (in case of multi-branch method)
In the case of the multi-branch method service, the inventory facility amount is counted by carrying out provisional selection in the route as in the direct acquisition method. At this time, the cable cores that are shared up to the input side of the branch device are in stock equipment until all the output terminals of the branch device are used, and even if the temporary selection is successful, the input of the corresponding branch device The equipment above the port on the side is not non-stock equipment, and provisional selection continues until all the output side terminals of the branching equipment are used.
In FIG. 12, there are three successful routes connected to the inside node and 4 successful routes not connected to the inside node by provisional selection for the current state of the upper multi-branch method. When the successful routes (1) to (7) are actually completed by using the cable 3 and the cable 4 by the inventory totaling table in which they are registered, the figure in the lower stage is obtained. In the intermediate rack (2), 7 terminals of numbers 2 to 4 and 5 to 8 are used.
Based on the above steps (i), (ii), and (iii), the total inventory equipment amount is written in the inventory total table and stored as a set inventory amount between routes.

(DB configuration)
FIG. 13 is a configuration diagram of a DB (database) according to the present invention.
The DB configuration according to the present invention includes an in-house wiring facility DB 803, an inventory management DB 802, an inventory totaling table 804 and an aggregation target table 805 held in the inventory management DB 802, and a control unit 801 that controls these DBs 802 and 803. Is done.
The in-house wiring facility DB 803 has a function of storing and managing basic information of communication media. In addition, the inventory management DB 802 holds the aggregation target table 805 and the inventory aggregation table 804, and the information in the inventory management DB 802 is updated every time the configuration of the in-house wiring facility DB 803 changes with daily opening work. To maintain.

A more detailed example of media inventory management is described below.
(Setting table for aggregation)
When carrying out inventory management, a route and a service for which inventory is counted are set. In this case, an example of setting the aggregation target table shown in FIG. 10 will be described.
・ Equipment configuration Outside node: Termination rack (1)
Relay node: Intermediate rack (1), Intermediate rack (2)
Inside node: Equipment (1)
Cable (1): Termination rack (1) ← → Intermediate rack (1)
Cable (2): Intermediate rack (1) ← → Device (1)

・ Service setting Route (1): Direct service Route (2): Multi-branch service

By performing the setting as described above, it is possible to set the inventory of the direct service in route (1) and the inventory of the multi-branch service in route (2) as the aggregation target.

(Update inventory summary table (direct receipt method))
In the following, referring to FIG. 11, an example of counting inventory and putting the acquired inventory quantity into the inventory tabulation table when performing inventory management of the direct-acquisition type service is described below.
STEP1
The connected terminal 1 in the device (1) that is the inside node is acquired, and then any terminal in the termination rack (1) that is the outside node is acquired. Provisional selection is made for direct service at both ends. At this time, since the connected terminal 1 in the device (1) has already been connected to the terminal in the termination rack (1), the selection fails.
STEP2
When the selection fails, the next connected terminal 2 in the device (1) is acquired, and a temporary selection is performed with an arbitrary terminal in the termination rack (1) acquired in STEP1. At that time, the successful selected route is stored as a successful route (1).

STEP3
Similarly, all the connected terminals in the device (1) are provisionally selected in order, and the route that has been successfully selected is stored as a successful route. Next, since all connected terminals in the device (1) have been acquired, if acquisition fails, the unconnected core 5 is connected in the cable 2 connected to the device (1) side. get. Temporary selection is performed between the acquired core wire 5 and an arbitrary terminal in the termination rack (1), and if the selection is successful, it is stored as a success route.
STEP4
The successful routes acquired in the above STEPs 1 to 3 are counted separately for the successful route connected to the inside node terminal and the successful route not connected to the inside node. In this case, the number of routes for which temporary selection has succeeded at the connected terminal in the device (1) and any terminal in the termination rack (1) is three routes of the successful routes (1) to (3). Since there is only one successful route (4) and the number of routes that have not been connected to (1) but have been successfully selected at any terminal in the termination rack (1) The inventory capacity of
Number of successful routes (inside node connected): 3
Number of successful routes (inside node not connected): 1
It becomes.
The interpretation of this result is that the number of routes successfully selected at the terminals of the mounted PKG in the device (1) is 3, and whether or not there is a PKG mounted in the device (1). This means that the number of routes that the selection is successful if PKG is installed is 1. It is assumed that the number of empty terminals in the termination rack (1) is greater than the number of successful routes.

(Update inventory summary table (multi-branch method))
Hereinafter, with reference to FIG. 12, an example of counting inventory and putting the acquired inventory quantity into the inventory totaling table when performing inventory management of a multi-branch service is described.
STEP1
The connected terminal 1 in the device (1) that is the inside node is acquired, and then any terminal in the termination rack (1) that is the outside node is acquired.
The provisional selection with the multi-branch transfer service will be performed at both ends. At this time, since the connected terminal 1 in the device (1) has already been connected to the terminal in the termination rack (1), the selection fails.
STEP2
Due to the failure of selection, the total number of provisional selections among the number of output terminals in the branch device existing in the route is counted. At that time, since there are output terminals (2 to 4) that have not yet been provisionally selected, any connected terminal 1 in the same device (1) and any terminal in the termination rack (1) that is the outside node are included. Select between terminals. At that time, the facility with the flag that has been provisionally selected is not a candidate. In this way, the route that has been successfully temporarily selected is stored as a successful route.

STEP3
When provisional selection is performed at all the output terminals (1 to 4) in the branch device, since there is no output terminal that can perform provisional selection, the connected terminal in the next device (1) is acquired. However, in this case, since there is only one connected terminal in the device (1), acquisition fails. Therefore, an unconnected terminal in the cable 4 that can be connected to a terminal in the device (1) is acquired, and a temporary selection is performed in the same manner. In this case, the temporary selection succeeds via the output terminal 5 in the branch device not connected to the route. In this case as well, a flag that has been temporarily selected is added to the output terminal No. 5, and there is an output terminal that has not been temporarily selected in the corresponding branch device, so all output terminals are temporarily selected. I can continue.

STEP4
The successful routes acquired in the above STEP 1 to 3 are counted separately as a successful route connected to the inside node terminal and a successful route not connected to the inside node. In this case, the number of routes for which temporary selection has succeeded at the connected terminal in the device (1) and any terminal in the termination rack (1) is three routes of the successful routes (1) to (3). Since there is only one successful route (4) and the number of routes that have not been connected to (1) but have been successfully selected at any terminal in the termination rack (1) The inventory capacity of
Number of successful routes (inside node connected): 3
Number of successful routes (inside node not connected): 4
It becomes.
The interpretation of this result is that the number of routes successfully selected at the terminals of the mounted PKG in the device (1) is 3, and whether or not there is a PKG mounted in the device (1). This means that the number of routes that the selection is successful if PKG is installed is 1. It is assumed that the number of empty terminals in the termination rack (1) is greater than the number of successful routes.

(Application example)
As described above, the inventory equipment amount in the communication station is defined as the total amount of equipment that can be opened between routes, and by performing real-time management, inventory management with a clear definition of vacancy can be performed. It becomes possible. According to the present invention, it is possible to instantly determine whether or not a facility can be opened by grasping available facilities before carrying out the selection process. Can be reduced.
Finally, the present invention is a medium inventory management method for speeding up equipment selection in a communication station and improving the efficiency of inventory management. First, the inventory management method is performed by specifying routes and services to be aggregated. To clarify. Next, provisional selection with necessary services between the target routes is performed, and the amount of equipment that can be opened is calculated and defined as the amount of inventory, making it possible for equipment managers to clarify inventory management. It becomes.
