Two problems with this... 1) If the RBOCs try to keep status quo with the T1 situation, the cable companies may eventually eat the RBOCs' lunch. 2) The RBOCs can deploy fewer HDSL-based T1s due to Near-End cross-Talk (NEXT) concerns... ADSL doesn't have a NEXT problem so they can deploy many more ADSL loops than HDSL loops in the same cable sheath... In this case, volume will win over keeping prices high... --zawada Paul J.
