Probably not. More likely your CAC ABI is set up to run in TR08 mode 
which is incompatible with standard T1 framing.

Check the LIU board (the Line Interface Board -- as opposed to the FXO 
or FXS cards) and look at the PROM. It usually will be marked TR08. If 
that is the case you will need to order a D4/ESF upgrade kit. If you 
have a 1.x revision TR08 chip, you will need P/N 750-0018. If you have a 
3.x revision TR08 chip, you will need P/N 750-0019.

Good luck!
