Abstract

PURPOSE:To locate a fault part early even in a system of a package with complicated constitution by allowing a sender side to make fault management and detecting a management code between a couple of packages. CONSTITUTION:A management code generating section 3 gives a management code '1'.'0'.'1' to a synthesis section 6 so as to insert the code to a location of an idle bit of an input signal 10, management code detection sections 4,5 provided respectively to packages 1,2 detect the management code and output alarm signals 20,21 from each respective package when the management code is in error. Moreover, a management code of an inter-package signal 11 is inserted to an input signal 10 having an idle bit by the synthesis section 6 to be an inter-package signal 11, and the code is detected by the management code detection sections 4,5. The management code is eliminated from a signal outputted from the package 2 and the output signal 12 with an idle bit is sent.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a transmission signal management system for digital signals used in data communication equipment, and in particular, to a transmission signal management method for transmitting digital signals used in data communication equipment, and in particular, to control the transmission of individual signals in the transmission section of data communication equipment composed of a plurality of packages. This invention relates to a transmission signal management method for identifying faulty packages.

[Conventional technology]

Conventionally, the transmission signal management system for this type of data communication equipment has been equipped with alarm equipment on the receiving side, but no equipment has been installed on the transmitting side to generate an alarm. Therefore, on the basis of alarms from both the sending and receiving sides, transmission/reception and multiple packages have to be separated individually.

[Problem to be solved by the invention]

This conventional data communication equipment does not perform any alarm detection on the sending side, so it has the disadvantage that it takes time to identify each package on the sending and receiving sides where a failure has occurred in a complex system. be. In other words, an alarm is issued only to the receiving side, and alarms are issued to devices and failed packages that pass along the way, and it is necessary to investigate the packages in all devices.

[Means to solve the problem]

The transmission signal management method of the present invention is a transmission ratio signal management method for a transmitter in a data communication device composed of a plurality of packages, in which a predetermined code is inserted into an empty bit fixed position of an input signal to the transmitter. The code is detected in each of at least one pair of packages to detect a failure in each package of the transmitter.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a signal format for explaining this embodiment. In FIG. 1, the management code generation unit 3 generates a management code °゛1°″・”o”・at the empty bit position of the input signal 10.
'1'' is inserted by the combining unit 6, and package 1.2
This management code is detected by the management code detection units 4 and 5 provided in each of
．． 21 is output from each corresponding package.

Incidentally, as shown in FIG. 2, the management code of the inter-package signal 11 is inserted into the input signal 10 having empty bits by the synthesis section 6, so that it becomes the inter-package signal 11.
It is detected by the management code detection section 4.5. The management code is removed from the signal outputting the package 2, and an output signal 12 in the state of empty bits is sent out.

〔Effect of the invention〕

As explained above, the present invention performs failure management on the sending side as well, and detects the management code between a pair of packages, so even in systems with complex packages, failure parts can be identified quickly. Can be done. Furthermore, since the management code is inserted and removed in a pair of packages, there is also the effect that the increase in circuit scale is small.
