System and method for real-time monitoring soft switching fax

Abstract

The system includes following parts and functions: main controller (MC) in use for controlling and configuring information; network interface module (NIM) and soft exchange establish load-bearing channel for controlled user to send and receive faxes as well as filtering and distributing the received data; fax protocol conversion module (FPCM) receives IP code flow transmitted by NIM, as well as converts IP code flow to TDM code flow and sends the TDM code flow to TDM exchange module; through Ethernet port, FPCM receives setting and controlling commands from MC; receiving TDM code flow sent by FPCM, TDM exchange module exchanges TDM time slot with fax demodulation module; through HDLC, communication is carried out between MC and TDM exchange module as well as unitive managements and calls are controlled by MC; through HDLC to communicate with MC, fax process module is in use for demodulating, saving or playing back fax data. The invention also discloses corresponding method.

Description

technical field [0001] The invention relates to a monitoring technology in the communication field, in particular to a system and method for monitoring softswitch faxes in real time. Background technique [0002] At present, system equipment capable of monitoring telecommunication switches has been put into commercial use, and these system devices can monitor all services of traditional digital program-controlled switches. [0003] Digital signal processing technology (DSP, Digital signal processing) is to convert analog signals or some signals in our real life into digital signals for mathematical processing. The signals that can be transformed include, for example, audio and video signals, temperature, velocity, pressure, position, and so on. After the signal is digitized and subjected to a series of calculations and analysis, it can be used to complete some specific functions required by users. [0004] Peripheral Component Interconnect (PCI, Peripheral Component Interc...

AI Technical Summary

Problems solved by technology

[0009] With the development of technology, telecommunication equipment based on softswitch technology will gradually replace traditional digital program-controlled switches. Both voice and fax are transmitted on the IP network based on Internet Protocol. Therefore, in the future all-IP network, the monitoring of fax will also be It will be a relatively strong demand from the security departments of various countries, and it is an important function that a monitoring system must have. However, the existing technology has not realized the effective monitoring of faxes.
