Its kind of hard to figure out exactly what you're asking based on the 
wording of the above, but I'll give it a try.

Yes, T1's do support callerid.  If you are asking whether asterisk is 
capable of generating callerid towards your T1 provider, the answer is 
yes.  Whether your T1 provider "accepts" callerid is dependent on their 
configuration and policies. Some will accept anything, others will not 
accept anything, some will accept callerid numbers "if" those numbers 
are within a range of supported phone numbers for your account (eg, did 
numbers).

Note those that will accept callerid will only accept calleridnum, not 
calleridname.

If you are talking about your T1 provider sending callerid to your 
asterisk box, yes they are capable of doing that. Its an option on their 
equipment they have to turn on.
