Here's my rant for the day: The one thing that's bugged me about Digium's model numbers is the difficulty in determining features just by looking at them. The one thing that is easy to tell is the maximum number of ports/channels the card will take. From there it gets harder. Analog is either TDM* or AEX*. PCI or PCI express can sort of be determined by whether it ends with a P except on the TE122?. Whether hardware echo cancellation is built-in, available or not present can sort of be determined for digital cards if it ends in 2 or 7 except on one port models. PCI card voltage? Again, sometimes you can use the last digit but not on one port models. If you want to know what a card's capabilities are you're better off just memorizing each part number. Maybe there's a scheme I'm just not capable of understanding here. Rant off. -Dave _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
