We were able to run the VOIP traffic using UBR, out network not being saturated, this may have helped, on a busy network, a lot of problems could have arrisen. What is nice, is that QOS is easy to enable in ATM. There are many reasons that ATM has not taken off, from a CLEC perspective, I believe it to be the superior technology. I would much rather have a 10 Mbps Ethernet feed from a company like Cogent but those links do not compare in pricing with DSL. > > -- > Christian Kuhtz <[email protected]> -wk, <[email protected]> -hm > Sr. Architect, Engineering & Architecture, BellSouth.net, Atlanta, GA, U.S. > "I speak for myself only.""
