In general, programmers have used simulation environments and cross-debugger techniques as the primary way to check the status and information of a signal.

The simulation environment described above provides an environment similar to the target system on the host, and then simulates the operation of the exchanger specific software blocks so that most errors can be detected and resolved early before being loaded into the target system. Also, the cross debugger technique is a source level debugger that provides the ability to debug a particular software block running on the target system on a host using Ethernet.

The conventional techniques described above are only available for specific software blocks because they depend on the host for signal tracking, so they can be applied to a large number of software blocks at the application level without changing the software blocks and operating system. This required problem has arisen.

And, using the makefile provided by the makefile generating means, extract only the names used in the program to ensure the consistency of information on processes, signals, property names for process or signal, mode definition, etc. during software development. By A means for generating a table of contents for generating a file, a means for generating signal related data for generating a file having a user-defined signal related information and a communication message data structure by receiving a common file generated by the make table of contents generating means; Analyze means for scanning the file generated by the signal-related data generating means to extract the information required for signal tracking and store the information in the form of a table, and to generate a final information table for signal output information by inputting such a table; A hand table, an index, a field name, and a field composed of a signal number, a signal name, a message data structure name, a message size, and an index for referencing field information of the data structure by receiving a final information table generated by the analysis means.

The signal data analysis and information generation area is composed of an analysis step 402 and a generation step 403. The compiler area includes a makefile generator ( 405, make table of contents generator 406, and make sections (407, 408).

Looking at the characteristics of the configuration as described above, in the analysis step 402 scans a file 401 having a user-defined signal-related information and a communication message data structure to extract the information required for signal tracking and store in a table form And, input these table to create final information table for signal output information.

In addition, the generation step 403 consists of a head table consisting of a signal number, a signal name, a message data structure name, a message size, an index for referencing field information of the data structure, an index, a field name, and field attributes. Generate an object code 404 that is combined with the field table being referred to and the operations that reference these tables.

In addition, the makefile generator 405 uses a make function provided by a current UNIX system for managing a separated compiler. Provide a makefile containing the time dependencies between the files and compiler instructions to perform the make.

In addition, the make table of contents generator 406 generates a common file by extracting only the names used in the program to ensure the consistency of information on processes, signals, property names for processes or signals, mode definitions, and the like during software development. It plays a role.

The user terminal 500 is connected to the subsystem-specific processors 501 to 507 loaded with the final execution modules through the RS-232c interface A to perform input / output operations for requesting and outputting signal information.

At this time, the functions of the processors are as follows.

OMP (Operation and Maintenance Processor) oversees a series of operations and maintenance functions for the system.

Therefore, the secondary storage device required for this is provided with an MT and a disk.

The MT includes charge records, statistics, maintenance and operation management information, and the disk contains general programs and data.

Man-machine processors (MMPs) enable communication between operators and systems, or between operations centers and systems.

For the dialogue between the operator and the system, VDUs (Visual Display Units) including the system console and printers for hard copying the output data are used.

Synchronous / asynchronous channels are used for data linking with the remote operations center.

The local disk is used to supplement the VDU's visualization and store command files.

The INP (Interconnection Network Processor) controls all the switch networks, such as searching, assigning and managing a call using a spatial switch.

In addition, NTP (Numver Translation Processor) manages the information about the route and number according to the configuration of the system, responds to the number translation request from each ASP, and performs the route control function.

The Access Switching Processor (ASP) performs all call processing functions that suggest searching by centralized number and call, and performs NO.7 maintenance, ASS maintenance and management.
