I know that there's a few people on this list who mess around with homebrew GSM networks and OpenBTS, so I'll offer these here first.
I am getting rid of my two Telular Phonecell SX5 fixed GSM terminals. These are 2G devices that present a phone line and a serial port. They have dial tone emulation and can allow a regular phone handset to send and receive calls. (There is some fax support but I've never used that functionality.) The serial port is directly connected to the GSM modem so that you can also use it for sending and receiving SMS text messages, which is the primary purpose it served here (so I could ping the house sensor network if the server line was down). The reason I'm getting rid of them is because 2G is being sunsetted in the USA and T-Mobile, the last 2G carrier, will dismantle its nationwide 2G network by the end of this year. DO NOT BUY THIS IF YOU WANT TO USE IT FOR THAT PURPOSE unless you are using a regional carrier you know will support it. On the other hand, if you want a fixed box (or both of them) for your own private GSM network, such as with an OpenBTS base station, then this will serve you hopefully as well as it has served me. Both units were purchased new and I have been their only owner. They include manuals, power supplies, spike antennae and power cords in the original boxes. SIM cards are not included and I have removed their old lead-acid battery backups for weight and because those died long ago. I'm asking $60 each, or $100 if you want them both, plus shipping. I'm open to other offers. Please E-mail me off list. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckai...@floodgap.com -- FORTUNE: You're wise, but not wise enough not to read this sort of drivel. -
