Class MSBearerCapability.GSM.Content.NonSpeech

  • All Implemented Interfaces:
    DataObject, FastSerializable, Serializable
    Enclosing class:

    public static final class MSBearerCapability.GSM.Content.NonSpeech
    extends AbstractLazyEncodedByteArray
    implements FastSerializable
    Class NonSpeech represents the non-speech forms of a MSBearerCapability. It represents part of a larger octet string; it is not transmitted on a network by itself.

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

     NonSpeech ::= SEQUENCE {
         transferCapability TransferCapability,
         dataProtocol       DataProtocol       OPTIONAL,
         access             Access             OPTIONAL,
         layer1Capability   Layer1Capability   OPTIONAL,
         layer2Protocol     Layer2Protocol     OPTIONAL
    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.

    The octet numbering in the above table is that used in the cited standard for the octets encoded here. Field names ending in ? are booleans: 1 for true, 0 for false.
