This appendix describes the fields in tables accessed through the Configure menu. The following legend refers to the Notes column. Refer to this legend when deciding whether to edit an NMT default value.
An asterisk in the Configuration Extraction Tool (CET) column or the Third Party Interface (TPI) column indicates that application supports a particular field. For instance, the CET extracts site names from the StrataView Plus database, so there is an asterisk in the site row of the CET column.
