Design and Implementation of Ethernet-Based VoIP Communication System Management Software

Abstract

In order to solve the higher cost of system maintenance and higher risk bringing by MSP430 MCU and DSP site commissioning by using emulator, the Ethernet-based telephone communication system management software was designed based on the hardware platform of VOIP telephone communication system, which realize the remote management, maintenance, and the DSP and MSP430 MCU software online update for the network telephone communication system. The management software developed in Visual C # platform, using a Socket to the network communications. This management software has been put into use, which shows the advantages’ of good stability, simple operation and work efficiency, etc.

Remote Update on Flash-Based Hydrologic Remote Terminal through GPRS Technology

“…Previous programs in the microcontrollers were mostly loaded in the field through Joint Test Action Group (JTAG) or Bootstrap Loader (BSL), and these two methods must be done on site, which were inconvenient for remote maintenance and update. For these defects, many scholars have studied the remote update deeply using different types of microcontrollers [2][3][4], but existing methods are still imperfect for complex procedures and link transmission, updated programs may break down during program execution [5,6]. As a product, stability is crucial, the situation of updated programs running away should not occur.…”
