Independent Direct Mode - Interphase 4538 Hardware Reference Manual

TDM Bus Configurations

Independent Direct Mode

In this mode, PA(7) = SWMODE_N = 1 and PA(0) = COMCLK_N = 1.
In independent direct mode, each framer can have its own rhythm. Each QuadFALC TDM
bus is directly tied to a CPM TDM bus and has its own clock and frame synchronization
signal provided by the QuadFALC. In NT mode, each framer can synchronize on an
external network reference clock provided on connector P4.
