clec vs ilec, how do you know who's lying?

Hello everyone, not sure if this is off topic or not since it is will be operational in nature if I can ever get the service set up. :-) I'm having the pleasure, or lack thereof, of ordering some data connectivity via a very large clec which requires the ilec to provide the local loops. Well we'

Providers that support prepending to specific remote AS's?

PBR needing to hit the cpu?
