PCM Input Clocks.
These inputs are used to sample the incoming PCM data/
CAS from the E1 or DS1 lines.
In Structured CES mode, ST-BUS format STiCLK is
4.096 MHz; Generic format STiCLK is 1.544 MHz or 2.048
MHz for DS1; or 2.048 MHz for E1.
In Unstructured CES mode, these pins accept 1.544 MHz for
DS1 or 2.048 MHz for E1.
Input Frame Pulses.
In Structured CES mode, these pins are input frame pulses
which set the frame boundaries for the incoming data and
CAS. These signals can be either multiframe or frame inputs.
Not used in Unstructured CES mode.
Serial PCM Data Inputs.
In Unstructured CES mode, each pin carries a 1.544 Mbps or
2.048 Mbps serial stream.
In Structured CES mode, each pin carries a 1.544 Mbps or
2.048 Mbps serial stream which contains a 24-channel data
stream in DS1 operation or a 32-channel data stream in E1
operation.
Serial PCM Signalling Inputs or Input Loss of Signal (LOS)
Indicators.
In Structured CES mode, these pins carry CAS signalling
inputs.
In Unstructured CES mode, these pins input LOS signals
from external LIUs.
