For the purposes of the present document, the terms and definitions in TS 25.401 [5] and the following apply:

Common Transport Channel: it is defined as a transport channel that is shared by several users i.e. DSCH [TDD], USCH [TDD], RACH, FACH [FDD and 1.28Mcps TDD -, E-DCH for CELL_FACH and Idle] and HS-DSCH.

Transport Connection: service provided by the transport layer and used by Frame Protocol for the delivery of FP PDU

[FDD – …] This tagging indicates that the enclosed text following the "[FDD – " applies only to FDD. Multiple sequential paragraphs applying only to FDD are enclosed separately to enable insertion of TDD specific (or common) paragraphs between the FDD specific paragraphs.

[TDD – …] This tagging indicates that the enclosed text following the "[TDD – " applies only to TDD including 7.68Mcps TDD, 3.84Mcps TDD and 1.28Mcps TDD. Multiple sequential paragraphs applying only to TDD are enclosed separately to enable insertion of FDD specific (or common) paragraphs between the TDD specific paragraphs.

[7.68Mcps TDD – …] This tagging indicates that the enclosed text following the "[7.68Mcps TDD – " applies only to 7.68Mcps TDD. Multiple sequential paragraphs applying only to 7.68Mcps TDD are enclosed separately to enable insertion of FDD and TDD specific (or common) paragraphs between the 7.68Mcps TDD specific paragraphs.

[3.84Mcps TDD – …] This tagging indicates that the enclosed text following the "[3.84Mcps TDD – " applies only to 3.84Mcps TDD. Multiple sequential paragraphs applying only to 3.84Mcps TDD are enclosed separately to enable insertion of FDD and TDD specific (or common) paragraphs between the 3.84Mcps TDD specific paragraphs.
