Custom means "AT&T Custom", not NI-1. For DMS-100/250, have the tech set the LT_DEF variable to U-459 (a Line Type Definition of U-459 is AT&T custom). I don't know why this is so misunderstood by Class 5 switch admins.

Do not use 5ESS emulation. Steer clear of NTNAPRI unless you own a Nortel brand PBX.
