Corporate comprehensive communication platform
Introduction:
XD corporate comprehensive communication platform is an advanced communication platform that Hangzhou Xinda Electronic Technique Co., Ltd. proposes and successfully develops for the first time based on many years’ experience in work related to SPC exchange, teleconference, command and dispatch as well as research and developing of signaling processing equipment. Its hardware is based on IPC and XD communication integration module, and its software is under the environment of Windows and adopts TCP/ IP protocol to provide advanced and reliable comprehensive communication service for users. On the basis of this platform, interactive teleconference, rapid command and dispatch, voice notification system and value-added telecom service can be realized.
XD communication integration module is a programmable multifunctional module as well as achievement of researchers’ studies at the company’s research institution. It integrates digital programme-controlled exchange network, support signaling and multi-E1 digital junction interfaces of R2/MFC Chinese No.1 and Chinese No.7 signaling, and PCM multichannel conference processor, satisfies units like clock system of ETSI 300 011synchronous requirement and PCM digital voice record-replay interfaces and has D10 bus that is developed by the company independently. Thus, it can be connected with any type of the company’s telephone interface card to realize network interconnection and resource sharing. In addition, it uses the most advanced dedicated chip in the world and is equipped with specific board card location technique and automatic detection method, which makes its stability, expandability and portability of application program stay at an advanced level in domestic industry and keep synchronous with international level.
