stream, and it delivers the contents of those codeblocks to the layer above. (2) A PHYSICAL LAYER, which contains the radio frequency and modulation
capabilities that may be invoked to establish the physical data channel: these
capabilities are fully described in Reference  and are only addressed within this
document as required for clarity. The Physical layer also contains PHYSICAL
LAYER OPERATIONS PROCEDURES (PLOPs) which provide the methods
of activating and deactivating the physical channel. A complete, detailed specification of the services provided by each layer within the Channel
Service is presented in Annex B. The first-time reader should digest Annex B before
proceeding further in this document.
1 Figure 2-1 represents a logical view of the TC System and physical implementations
may not necessarily correspond to the flow of operations implied by the figure. 2 This Recommendation primarily specifies the data structures and procedures flowing
ACROSS the layers from the sending to the receiving end of the TC System, since
these have a direct...
