Data Sheet
Signal Processing Channels (CHx)
These blocks do the transmission processing for the voice channels. Part of the processing is analog and is interfaced to the VIN
and VOUT pins. The remainder of the processing is digital and is interfaced to the Time Slot Assigner (TSA) block.
SLIC Device Interface (SLI)
This block communicates digitally with the SLIC device circuits. It sends control bits to the SLIC devices to control modes and to
operate LEDs and optocouplers. It also accepts supervision information from the SLIC devices and performs some filtering.
