shareControlHeader (6 bytes): Share Control Header (section 2.2.8.1.1.1.1) containing information about the packet. The type subfield of the pduType field of the Share Control Header MUST be set to PDUTYPE_CONFIRMACTIVEPDU (3), and the PDUVersion subfield MUST be set to TS_PROTOCOL_VERSION (0x1).

shareID (4 bytes): A 32-bit, unsigned integer. The share identifier for the packet (see [T128] section 8.4.2 for more information regarding share IDs).

originatorID (2 bytes): A 16-bit, unsigned integer. The identifier of the packet originator. This field MUST be set to the server channel ID (0x03EA).

lengthSourceDescriptor (2 bytes): A 16-bit, unsigned integer. The size in bytes of the sourceDescriptor field.

lengthCombinedCapabilities (2 bytes): A 16-bit, unsigned integer. The combined size in bytes of the numberCapabilities, pad2Octets and capabilitySets fields.

sourceDescriptor (variable): A variable-length array of bytes containing a source descriptor (see [T128] section 8.4.1 for more information regarding source descriptors).

numberCapabilities (2 bytes): A 16-bit, unsigned integer. Number of capability sets included in the Confirm Active PDU.

pad2Octets (2 bytes): A 16-bit, unsigned integer. Padding. Values in this field MUST be ignored.

capabilitySets (variable): An array of Capability Set (section 2.2.1.13.1.1.1) structures. The number of capability sets is specified by the numberCapabilities field.
