Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

1 is a block diagram of a circuit distribution apparatus to which the present invention is applied.

The broadband line distribution device receives the channels of the synchronous transmission signals AU4, AU3, TU11, and TU12, processes the distribution / branching function on a line-by-line basis through the cross connection, and then outputs the synchronous transmission channel signals back to the synchronous device.

The circuit distribution control management unit (DCM) 10 interworks with the connection management table 11 to establish a channel management database that is inputted and outputted when the transport channels are cross-connected, and the connection management table 11 is connected to the channel configuration change request. Provide the necessary information.

The circuit distribution control management unit 10 performs a control function for input / output channel management and cross connection necessary for distribution / branching processing of a line processed by the broadband switch control unit (XCC) 19 to process line cross connection, and The switch control unit 19 changes and manages the changed information in the channel management database storage unit 16 again, and manages channel configuration information of transmission devices connected to the broadband circuit distribution unit (BDCS) 17.

Therefore, in order to perform these functions, the circuit distribution control management unit 10 transmits and receives data through message queues with neighboring blocks requiring data transmission and reception, and the broadband switch control unit 19 and the system operation management unit (for data processing). A message is sent and received to the SOM 12, the information model server (IMS) 13, the user interface control unit (MMC) 14, and the database management unit (DBM) 15.

When the operator requests a line change, the user interface control unit 14 converts the requested content into a message and transmits the message to the line distribution control management unit 10 via the information model server 13 and the system operation management unit 12.

The procedure in the circuit distribution control management unit 10 for processing the message received through the system operation management unit 12 is as shown in FIG.

2 is a block diagram of a circuit distribution control management unit (DCM) to which the present invention is applied.

When the message transmitted from the system operation management unit 12 is received by the system operation management message (SOM MSG) receiving unit 101, the message analyzer 102 analyzes what is requested. Here, the contents of the message analysis include device initialization for configuring a channel when the circuit distribution device is installed, a channel configuration change request for the operator to change the channel during device operation, and a configuration inquiry for the device configuration information.

If the message analysis result is device initialization, the system initial information processing unit 103 reconfigures the configuration information necessary for initialization into a message, and then changes the configuration of the channel through the broadband switch control message transmitter 106 to cross the reconstructed message. Transmission to the broadband switch control unit 19 that functions as a connection.

The initialization request information received by the broadband switch control unit 19 is transmitted to the broadband switch control message receiving unit 110 via line connection information.

The broadband switch control message receiving unit 110 receives the result processed by the broadband switch control unit 19 through the message queue and transmits the result to the connection management inquiry / change processing unit 109 and manages the input / output channel information. It is stored in the table 11.

After being stored in the table, these processing results are output to the user interface control unit 14 via the system operation management unit 12 and the information model server 13, and the result message received by the information model server 13. Is transmitted to the database manager 15 to store information about the channel configuration change in the database storage 16.

If the message analysis result of the message analysis unit 102 is a channel configuration change request, the configuration change information processing unit 104 reconfigures the configuration information to be changed, and then reconstructs the reconstructed message through the broadband switch control message transmission unit 106. A configuration change occurs and is transmitted to the broadband switch control unit 19 that functions as a cross connection.

Subsequent processing is the same as the procedure for processing the device initialization message.

On the other hand, if the message analysis result of the message analysis unit 102 is a configuration query request, the received message is transmitted to the configuration query information processing unit 105, the configuration query information processing unit 105 reconstructs the information requested for inquiry and connected If it transmits to the management inquiry / change processing unit 109, the connection management table 11 retrieves the result.

The information retrieved from the connection management table 11 is reconstructed into a message and the result is output to the user interface control unit 14 via the system operation management unit 12 and the information model server 13 through the system operation management message transmission unit 107. Then, the result message received from the information model server 13 is transmitted to the database manager 15 to store information about the channel configuration change in the database storage 16.

The most important functions handled by the circuit distribution control management unit 10 manage the processed result of the channel configuration change and the signal channel, and generate the connection management table 11 to manage the input / output transmission channel for each synchronous signal unit.

Accordingly, the generated connection management table 11 configures a database with eight tables to manage channel information. In addition, the connection management table 11 manages channel information based on the synchronous transmission signal processing path, and is composed of Tables 1 and 2 representing input and output tables for managing four channels, respectively.

Looking at the structure of the connection management table for managing the input channel and output channel used in the present invention.

In the connection management table 11, for storing, inquiring, and changing data, the connection management table 11 should have a reference column for retrieving data. For this purpose, each table composed of signal path units has a signal type, a unit name for processing a signal, and a high speed channel number. Each of these four bytes is allocated by retrieving the data with the reference key value by allocating one byte to each of, and the low speed channel number.

The method of storing the connection management table 11 stores and manages the contents of the database by separately securing logically separated memory areas, and the memory used when changing channel information managed by the connection management table 11 is a service function. As a result, queues for setting and releasing distribution, branching, combining, test signal branching, and test signal combining are allocated to unidirectional and bidirectional directions, respectively, to store data necessary for management of configuration change.

As can be seen from Table 1, in the database constituting the connection management table 11, Ho4Int2OutCm manages configuration information in the order of AU4 (VC4) channel based on the AU4 (VC4) input channel, and HoInt2OutCm is Configuration information is managed in order of AU3 (VC3) channel number, and LoInt2OutCm manages configuration information of AU3 (VC3) signal distributed or branched to the channel of TU1 stage. In addition, TsmLoInt2OutCm manages configuration information of channels distributed or branched to the TU1 (VC1) end channel.

As can be seen from Table 2, the output channel is the same type as the input channel, and is managed based on the output channel.

Ho4Out2IntCm manages AU4 (VC4) channels based on the output channel, HoOut2InCm manages output AU3 (VC3) channels, and LoOut2InCm configures AU3 (VC3) channels distributed or branched to TU1 (VC1). Manage it. In addition, TsmLoInt2OutCm manages output TU11 / TU12 channels.

Twelve service queues are allocated to handle configuration management services for storing these services when the installation initialization of the broadband circuit distribution unit and the configuration information of the active circuit distribution unit are changed. One-to-one and one-to-many connection management queues of these function queues. The structure of the table is shown in Tables 3 and 4.

The structure of the one-to-one and one-to-many connection management queue table used in the present invention is as follows.

The queues for processing these services vary depending on the type of service and include one-way distribution, branching, combining, test signals, branching, and services that store information that requires combining test signals, the same two-way service, one-way distribution, branching, and combining. , Test signal branch, test signal combination release service, the same bidirectional distribution, branch, combination, test signal branch, test signal combination release service, service for storing information that does not exist signal requesting configuration change, distribution, Branch, combining, test signal branch, service that stores the signal that requires the test signal combination when the signal is already in use, distribution, branch, combining, test signal branch, signal information that is not in use by signals that require the release of the test signal combination Service to store, service to store information that could not be distributed due to low speed signal distribution, and to not to distribute high speed signal. The service for storing the missing information uses a queue for storing one-to-one configuration information as shown in Table 3.

That is, CN_uni_queue, CN_bi_queue, DIS_uni_queue, DIS_bi_queue, NOT_exist_queue, CN_used_queue, DIS_used_queue, LSW_unused_queue, and HSW_unused_queue, which handle one-to-one channel configuration changes, use queues in Table 3.

Disabling one or all of the one-to-many distribution and branch output signals, the information you want to connect multiple output signals to one input signal, and one-to-many output of the distribution and branch information If you have a list number, use the cues of Table 4. That is, CN_broad_queue, DIS_br_queue, and BR_list, which process one-to-many configuration information, use queues in Table 4.

3 is a flowchart of a channel configuration change procedure according to an embodiment of the present invention.

First, after receiving a message transmitted from the user interface control unit 14 or the broadband switch control unit 19 of the circuit distribution apparatus (301), it is determined whether there is an error in the received message (302).

As a result of the determination, if an error has occurred, it returns to the beginning again, and if there is no error, it checks whether the received message is sent (303).

If the message transmission destination is the user interface control unit 14 or the system operation management unit 12, it is determined whether it is a configuration inquiry message or a message for requesting a channel configuration change or initialization (305).

As a result of the determination, if it is not a configuration inquiry request message, it is recognized as a channel configuration change request message, and a message is sent to the broadband switch controller 19 (306). If it is a configuration inquiry request message, the message is analyzed (307) and the channel configuration information is retrieved. (308)

If the message transmission destination is a message that a configuration change request for which channel switching is performed by the broadband switch control unit 19 has been processed, the message is transmitted to the connection management table 11 for storing the high speed signal processing board and channel number (304).

Thereafter, it is determined whether the changed configuration information is input channel information or output channel information (309, 311).

If the changed configuration information is input channel information, the channel information is retrieved from each corresponding table according to the signal type of the change channel in the input connection management table 11 (310), and if the output channel information, the change channel is output from the output connection management table 11. Channel information is retrieved from each corresponding table according to the signal type of the signal (312).

Next, it is determined whether the information retrieved from the connection management table 11 is configuration inquiry information (313).

If the determination result is the configuration inquiry information, the result is converted into a message (315), and the result message is transmitted to the system operation management unit 12, the user interface control unit 14, and the database management unit 15 (316).

In addition, if it is not the configuration inquiry information, data is stored in the service queue according to the service type of the configuration change information, and it is changed to the configuration information for which a change request is made to the channel retrieved from the connection management table 11 (314). At this time, the change information is composed of the result message in the same manner as the configuration inquiry information (315) and transmits the result message to the system operation management unit 12, the user interface control unit 14, and the database management unit 15 (316). .

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.
