MSBearerCapability.GSM.Content

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.

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

Octet 6g*	ext. 1	Acceptable channel codings extended			Asymmetry indication		Spare (00)
Octet 7*	ext. 1	Layer 2 id. (10)		User information layer 2 protocol

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.
