extends AbstractLazyEncodedByteArray
    Class O6b represents data that is relevant to octets 6b* to 6g*. 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. 

     O6b ::= SEQUENCE {
     parity                            Parity,
     networkIndependentClockOnReceive  NetworkIndependentClockOnReceive,
     networkIndependentClockOnTransmit NetworkIndependentClockOnTransmit,
     intermediateRate                  IntermediateRate,
     o6c                               O6c 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.

    Data Encoding -based on 3GPP TS 24.008 v4.17.0 (2007-09) §10.5.4.5 pp343-361

    The octet numbering in the above table is that used in the cited standard for the octet encoded here.

    There is a static condition in standard 24.008 that says if octet 6b is present then octet 6c shall also be present, in the GSM encoding. Contradicting that, the standard allows the ext bit in octet 6b to be 1, which would indicate that there is no following octet 6c. As a compromise, this API offers field O6c as an OPTIONAL field, but with this recommendation: you should always provide a value for field O6c.
