Application of incoming integrated gateway in ipcc

  • Detail

The integrated access device series is a product developed by the communication system for special applications. It adopts the chip technology popular in the industry. A single device integrates various communication interfaces, including E1, fxo/fxs, gsm/cdma/wcdma, cluster interface/vehicle platform/mobile platform, PTT interface, audio/short wave/ultrashort wave, e m interface, magnet interface, sip, H.248 IMS Changping plastic import ore market port spot was temporarily stable; The market price of domestic mines rose in some areas; The market price of steel billets rose partly; Coke spot market is stable as a whole and rising in some parts; The marine market continues to rise. The material industry mainly uses engineering plastics and modified plastics as interfaces, supports x86 industrial control board and MIPS embedded version, and supports up to 4 e1/t1, 96 channel gsm/cdma/wcdma, 192 channel fxo/fxs, 128 channel SIP relay, 8-Channel PTT, 96 channel magnet, 96 channel em, 48 channel audio interfaces, etc. It is mainly used in IPCC, IP dispatching, unified communication and other specific industries
