PCM Clock: For PCM Highway operation, [PCM_CLK_C] is the
single transmit and receive data clock input pin for the channel
C PCM Highway interface. [PCM_CLK_C] becomes a clock
source output when the GCI to PCM Highway clock and frame
synchronization conversion are enabled.

PCM Frame Synchronization Clock: For PCM Highway
operation, [PCM_FSC_C] provides the Frame Synchronization
Clock input (usually 8 kHz) for the channel C PCM Highway
interface. [PCM_FSC_C] becomes a frame synchronization
source output when the GCI to PCM Highway clock and frame
synchronization conversion are enabled.
[PCM_TSC_C]
[DCE_CTS_C]
PIO44
OD
PCM Time Slot Control C enables an external buffer device
when channel C PCM Highway data is present on the
