Class OriginalCalledNumber

  • All Implemented Interfaces:
    DataObject, FastSerializable, Serializable

    public class OriginalCalledNumber
    extends AbstractLazyEncodedByteArray
    implements FastSerializable
    Class OriginalCalledNumber represents an original called number. It represents the ASN.1 OCTET STRING type Core-INAP-CS1-DataTypes.OriginalCalledPartyID.

    The API offered by this class is as if the type were specified in ASN.1 as follows.

     OriginalCalledNumber ::= SEQUENCE {
         nature        Nature,
         numberingPlan NumberingPlan,
         presentation  Presentation,
         address       DigitString
     }
    The class takes care of encoding the field values into a byte-array and decoding field values from a byte-array, the encoded representation being as tabulated below.

    Data Encoding - based on ITU-T Q.763 (12/1999) §3.39 p45
    87654321
    Octet 1Odd?Nature of address
    Octet 2SpareNumbering planAddress presentation restrictedSpare
    Octet 2+1Address digit 2Address digit 1
    .........
    Octet 2+nFiller (0000) or Address digit 2nAddress digit 2n-1

    The length of the data encoding depends on the length of the address. The octet numbering in the above table is based on that used in the cited standard, tweaked to ease specification of the address encoding. Field names ending in ? are booleans: 1 for true, 0 for false.

    Each digit of the address field is encoded into a semi-octet, and if there is an odd number of digits then the last semi-octet is assigned a filler. Unless overridden by a particular StringCodec, the filler is 0 and the encoding to semi-octets is as tabulated below. Since 0 is also the encoding of a valid digit, a separate indicator is required to encode whether there is an odd number of digits or not.
