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. -- Steven Critchfield <critch@basesys.com>
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?

I know Wasam (ala Farfon) is try to build something like this using IAX, but is anything currently available? Nabeel
I haven't used their 24 port gateway, only the four port gateway, but they have been excellent. http://www.mediatrix.com/products_devices.php?prodid=3 Paul Paul Mahler www.signate.com

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. FXO costs more usually because that is typically the Office station side that has much lager power requirements. Where FXS is the phone/customer side of the Communications. .

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.

Of course you could look around ebay for cheaper channel banks too.> > Voip supply has a few 24 port gateways that are FXS based. The biggest > > one for FXO is 10 ports.
