I know that in Chicago, as part of your ICA, you had to connect to the 
sector tandems, however, you could 'overflow' onto another tandem if necessary.

I was under the impression (now remember, this is 1996-1998 timeframe), that the 
'not taking kindly' reason was that Wabash and Dearborn Tandem switches were being 
overloaded by all the CLECs locating switches in the loop area to take advantage of
cheap transport...  (MFS/Worldcom/Intellinet/whatever they were called that week 
at RVC with that nasty nasty, nasty, E1-native Ericom switch, 
Focal over in the Floorshime building, Teleport/TCG up in the Sears Tower, 
and all the other carriers that I can't remember anymore ;)

Weren't the ICA's timed?  I would have assumed you would have been grandfathered
until you reupped your ICA, although, you did have the right to 'use' another party's
ICA during the beginning ICA negotiations, so if they didn't change the wording I
guess you would have been stuck.  But... if you're profitiable, who pulls out 
facilities anyways?
