X100P mod or USB relay box, RE: [Asterisk-Users] Line Override Device
The best solution would be an enhancement to the X100P card. If the 2nd RJ jack was a pass through for the line except when the card had power and was initialized. Some kind of watchdog functionality would also be nice so that if, for example, Asterisk dies then pass through functionality would take effect after n seconds. This would probably mean adding a relay to the board which would raise to cast a little. But, as the original poster indicated this is critical for a serious system. An alternative would be an extra relay box, maybe powered by USB. One mode could be to switch based on presence of power, another mode could require periodic watchdog pings via the USB. I always wanted to build something using a USB flavored PIC... I can see this for small offices (like ours). We have 4 incoming lines in a hunt group. If Asterisk is not running I want one of those lines to ring the receptionist (maybe using a simple dedicated phone since they'd otherwise have an IP phone) and the others looped for busy. I can see a box with USB and 12 RJ jacks (4 x (1 in, 2 outs)) to make that work. Would anyone buy a product like that? -reed At 07:12 AM 7/14/2003 -0500, jltaylor wrote: This power failure thing does not have to be complicated. A few solutions come to mind: 1) A 3,5,12 (whatever is needed) power supply (wall wart)used with a relay (DPDT). When the wall wart has power, the computer takes the call. When power fails, the POTS line falls in to place. Now, this does not delay while the computer is booting up. 2) A basic stamp computer - about $25-30. It has 8 programmable i/o pins that will drive relays. One pin monitors either a wall wart or 5v from one of the plugs on your computer's power supply. When pin 1 goes low (no power) relay kicks in to bypass computer and connect POTS line direct. When power returns program jumps to a sleep or delay statement for xMINS until computer boots. And then releases relay for normal operation. www.parallaxinc.com and resellers.

We get a relatively small number of calls but any one of them could be worth a large stack of cash for our business. A stinky phone system can make us look bad. The main reason I'm looking at Asterisk is to improve the reliability and control over our phone system. All the other great things it provides really are secondary for the folks who pay my salary. Only if you aren't pulling power from the USB bus. There isn't much there. There may be just enough depending on how many relays are needed, but it would be too close. I agree, better off not trying to get power from there. I do like the idea of some kind of watchdog functionality. Simply having power isn't sufficient to trust that a call is getting routed. -reed ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users

Re: X100P mod or USB relay box, RE: [Asterisk-Users] Line Override Device
The Voicetronix Openline6 and Openline12 cards have the functionality you want built in. You can configure (jumpers) which ports are FXO and which are FXS (in groups of 2 IIRC) and 1st FXO goes to 1st FXS etc. in case of power failure. Apparently these cards work with Asterisk (chan_vpb). I think cost is AU$1500 and AU$3000 for 6 and 12. cheers, Wooody On Mon, Jul 14, 2003 at 02:17:59PM -0400, Reed Wade wrote: At 12:57 PM 7/14/2003 -0500, you wrote: This makes me think that you could take this a step further too and incorporate an external power supply and a relay that could interupt mains power so that you could power cycle the PC if the watchdog had power to operate and the PC wasn't responding or generating pings. i like that -reed ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users -- Woody ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
