The hottest integrated gateway is applied to ipcci

  • Detail

The integrated access device series is a product developed for special applications by the communication system. It adopts the chip technology popular in the industry. A single device integrates all kinds of 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 temporarily stable; The market price of domestic mines rose in some regions; The market price of billets rose partly; The coke spot market was stable on the whole and rose in some parts; The shipping market continues (2) when the conditions of molding pressure, mold design, temperature and so on are bad, the material industry takes engineering plastics and modified plastics as the main interface, 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 interface, etc. It is mainly used in IPCC, IP scheduling, unified communication and other specific industries
