Nice huh?
When we moaned to our SE's about this the response was, "Just move to fractional T3's". It appears that Cisco is now try to drive carrier behaviors in addition to end-user behaviors.
We are working on a work around using the AIM-ATM with two VWIC-2MFT's. But this also means we have to introduce ED code using T train into our *stable* GD mainline environment.
