I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Can you expand on the question a little more. What type of T1 is this (T1 from carrier or Pt-To-PT T1)... And of course what is the end goal of the request to make sure I understand this correctly.

As I read this I feel like you are asking if you can channelize a T1 that is not provisioned for services by a carrier but you want to use the "Extra" channels to activate services. 8 of the total 24 are configured and available but  the rest are not used?
