Are you using a terminal to talk to the CAC? Depending on configuration 
you may have the DIP switches disabled and changing them will do no 
good. Connect to the CAC and ask it for the T1 configuration to verify 
what it really is.

Also make sure you rerun ztcfg after any changes to zaptel.conf.

What does zttool tell you?
