Interesting points. I can see things like video conferencing\streaming being important considerations (for the upload and jitter you described above). For high bandwidth applications I can see the need for circuits on the SONET ring. For run of the mill internet access though I don't see the need. Hell I've seen call centers run off the cable co, VOIP and all.

Yes but short of a piece of paper in all practicality the leased lines are near as likely to go down as the regular connections. Also you can get two different feeds from two different providers (say FIOS and cable) and still pay next to nothing compared to the DS3 with a more robust connection. The SLA doesn't seem to justify THAT much of an increase to where people pay upwards of $1000 for 1.544 Mbps.

comment Why do modern routers not require clock settings anymore?
Thanks. I thought T1 and T3 (could have) the same physical layer (coax). I didn't think there was a "ds3 card", I thought it could be used for a T1 or T3 connection in which case how would it know what standard to use? Back in the CSU\DSU days could you set the clock to whatever you wanted or did the telco still provide it? If so then I suppose setting clocking is only useful in the lab and for QoS as you said.
