No crazy carrier diveristy, etc. All just T1's with other customer T1's on
Channelized DS3's in a PA-MC-T3 in a 7200:

Here is a really good curve ball. My crunch was we had a new customer
turning up this morning that was going to do MLPPP so I figured we would
have a problem, but it worked fine. I will go back through and double check
the circuits again. Has anyone ever seen the need to remove parts from the
config and recreate them ? Maybe remove, reboot, rebuild ? This is rather
bizarre !
Thanks
