19、the definitions of the parameter types used in this Standard.1.1 CHOICECHOICE is used to select one of mutually exclusive parameters. The encoded type identifier used isthe chosen parameter type.Optional CHOICEs may be extended in future releases.1.2 DigitsTypeThe DigitsType parameter type is based
20、on the Digits parameter defined in Section 3 of ANSIT1.114-1988. Where there are differences, this Standard takes precedence.New address parameters each use a unique and distinct identifier and an IMPLICIT DigitsType. Thisallows messages with multiple address parameters to be decoded by examining on
21、ly the messageidentifiers.1.2.1 DigitsType variant for BCD digitsField Value Type Reference NotesIdentifier DigitsType IMPLICIT OCTET STRINGM Part 550 Section 1.2Length 4 or more octets M Part 550 Section 1.1bContentsHGFEDCBAocteNotesType of Digits 1Nature of Number 2Numbering Plan Encoding 3Number
