1.General description Gsm fwt-8848 is a gsm to analog converter(single port, insert 1 sim card only), the device can produce a fxs line to allow a regular phone to be connected and used just like a local landline(pstn) except your calls will go out the gsm network. This device can both receive and make calls. The main application is: connecting the rj-11 fxs line to connect ordinary telephone set for voice call; to connect pbx for call extensions; to connect billing systems for public phone use; to connect voip fxo gateway to realize voip call termination; to connect alarm system for security purpose, etc. It is not a voip gateway, nor a gsm+voip gateway, it is a gsm fixed wireless terminal that produces an analog fxs phone line . 2.Features: 1)frequency:gsm 900/1800mhz or gsm 850/900/1800/1900mhz 2) it is a 1 channel gsm gateway which has 2 rj-11 outputs for extensions; 3) it can connect with ordinary telephone set, pbx , voip gateway, billing meter etc. ; 4) dialing tone frequency:450hz; 5) employ industrial module to make; 6) can adjust dial interval from 0.5sec to 9 secs by setting up from telephone set; 7) can adjust voice volume by setting up from telephone set; 8) sim card supported (1.8v, 3v); 9) caller id display; 10) dtmf dialing; 11) bell signal; 12) polarity reversal; 13) the rj-11 socket which connect the phone or billing system for metering purpose; 14) antenna socket (sma); 15) ip presetting; 16) working status and signal strength by led indicator; 17) imei change (optional). 18) back up li-ion battery( optional) 7.2v 1300mah.Standby 24hrs, talking time: 2.5hrs.
Mine detection cable is mainly used in various oil and gas Wells with Oil well wax removal, viscosity reduction and coagulation reduction, coring and well logging, perforation etc., can also be used in ocean research and river, harbor, water conservancy hydrological measurement, as well as coal field geological prospecting, geothermal well logging, etc.,The detection cable is connected with the sensor and the signal terminal, which has a strong anti-interference signal transmission function.
(1)Military cable for ships and oil platforms are suitable for fixed laying of ships and oil platforms, mainly used in power, lighting and control systems.
