Notes/Equations
  1. This model is used to divide the bit sequence of one CCTrCH frame into different DPDCHs.
    Each firing, Mp tokens of out signal are produced when Mp × Np tokens of in are consumed. Refer to the following table for the value of Mp.
    The DL_PhyCHType parameter is used only when LinkDir = Downlink; UL_DPDCHType is used only when LinkDi = Uplink.
  2. When multiple dedicated physical channel are used (Np > 1), the input bit sequence is divided among these channels. Mp × Np input tokens are one frame of CCTrCH data bits. All physical channels belonging to the same CCTrCH use the same SF. Thus, the bits of one CCTrCH frame are equally divided into Np different physical channels. Each channel has Mp tokens in one frame.
