RE: [Asterisk-Users] Any 24 (or 30) way FXS PCI cards?
Just found a 12 port single card with opensource drivers 12 user configurable FX0/FXS analogue ports for $1,680 at asterisk mall ( http://www.asteriskmall.com ). I am not sure how well this card works with asterisk. Has anyone used these cards? Voip supply has a few 24 port gateways that are FXS based. The biggest one for FXO is 10 ports. They are not cheap the both cost about $2000 USD. a Channel bank with a T1 card will cost you about the same at least with a FXS ports.

Hi Mr. Alsina, We are currently using Asterisk SIP server and 3 Quitum A800 for office used. Our Quintum run in SIP and work well. Im sure you can find refurb quitum that cost half the brand new... or you can look on the new Quintum AX series hence the A series were phaseout already. I can help you on configuration free...

Re: [Asterisk-Users] Any 24 (or 30) way FXS PCI cards?
It seems to me silly to have a T1/E1 card to connect to a channel bank when you could just have a 24/30 way FXS card in the slot in the first place. Does such a thing exist? Wouldn't Digium have a lot of customers if they could produce one for say $1000 retail? Trouble is power. Unless there is more power made available, you may not be able to drive the ring voltage of several consecutive lines at once. Take for instance the Adit 600, it has a 130w power supply for just 25 ren capability. Think of the troubles that would cause trying to be regulated through your standard PC PSU of 300w. Won't you just love trying to diagnose random reboots right after a phone call comes in and over draws your PSU capacity and it goes into short protection where it begins pulsing power. The entire telephony system relies heavily on statistical probabilities, including central office switches, inter-office trunking, and ringing. Applying the above thought process to a central office, there is no way a single central office could possibly ring all telephones associated with that office simultanously. The ring generators could never handle it. Likewise for a pc card supporting 24 fxs lines. The probability of three or more lines ringing at exactly the same time are very small. With at least a little engineering forethought, its not that difficult to create ring cycles where ports 1 through 6 ring during some period, followed by 7 through 12, etc. (That's actually how most central offices handle ringing now with a couple of exceptions.) A bigger issue is really oriented around how many ringers exist on a single fxs port, and that _could_ be limited by specifically limiting user implementation (via specs) to one phone per port (or whatever), etc. Couple that with the fact that current ringer designs require substantially less power then the old electomechanical ringers, it certainly isn't that difficult to design a PC board to support 24 fxs ports. ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Yeah, with the most obvious except being that in a very large number of cases, subscriber loops are now serviced by SLC/DLC systems, instead of direct analog transmission from the CO :-) However, I'd bet money that the SLC/DLC systems use this technique as well, for the very same reasons. ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Won't you just love trying to diagnose random reboots right after a phone call comes in and over draws your PSU capacity and it goes into short protection where it begins pulsing power. The InterTel Axxess had a good solution to this. Each station card had it's own ringing generator which produced ringing voltage at about 70 volts. It worked for most things but we had problems with a few modems and double-gong ringers. If you needed more, you would move a jumper on the card which would disable the internal generator. Then, you would provide 90/20 on the 25th pair of the AMP connector. In my mind, I imagine something very similar. It would look like an old SCSI card from the back of the PC with the big 25 pair connector. Pairs 1-24 would be the station lines and pair 25 would be for the external ring generator. --Shane ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [Asterisk-Users] Any 24 (or 30) way FXS PCI cards?
I think first we would need to clarify the use of the term FXO in this context. I'm not a telco expert by any stretch, but it appears to me the term is used misleadingly sometimes. It seems to me that an FXO port is a port that you can plug an external phone line into - it can then allow you to dial calls out on that line, or receive calls in on that line. I see all these FXS/FXO SIP devices on the market where the FXO port is just a 'pass-through' for power-failure protection, or it allows the connected phone to dial a string that lets them bypass the PBX and use the POTS. From my minimal knowledge that isn't really FXO. Is it? I'd like to see an ethernet FXO device that does what a Zap FXO device does. If it's out there, can someone point me at it? regards, Paul - Original Message - From: Nabeel Jafferali [EMAIL PROTECTED] To: Asterisk Users Mailing List - Non-Commercial Discussion asterisk-users@lists.digium.com Sent: Saturday, March 19, 2005 10:04 AM Subject: RE: [Asterisk-Users] Any 24 (or 30) way FXS PCI cards?
