The deletion of an entry in the DNI or GDTR table can be accomplished by the function DELETE. To delete an entry in the GDTRSR table use the function CHANGE by setting DNISRULE to zero (e.g. CHANGE-DNIT:GDTRSR,<TGRP>,0;).
To delete an entry in the DNI table, the INTRTDN parameter must be specified. Deletion of the entry cannot occur if the internal routing number is still being referenced by the GDTR table. If AMO DIDCR was referencing this internal routing number, it will be intercepted. To delete an entry in the GDTR table, the GDTRRULE and DGTSTR parameters must be specified.
