The MGC Info Field

This appendix provides further information about the MGC Info Field (Tag 4031), described in "Billing Interfaces," the "MGC Info Field (Tag: 4031)" section. The MGC info field consists of several sub-fields, the sub-fields are stored within the value section of the VSC info field without any Tags and values. The MGC Info fields provide the customer with backward compatibility to MGC Release 5.0 and earlier.

MGC Info Subfields

Table C-1 presents each sub-field with its exact position within the value section of the VSC info field.
