Test Modes
Each SICOFI
4-μC channel has four test loops that feed the analog input signal back to
the analog output (analog test loops), and five test loops that feed the PCM input signal
back to the PCM output.
Note: The signal path can also be cut off at two different points per receive and transmit
direction.
9.1
Analog Loops
The four analog loops feed signals from the transmit path back into the receive path.
Figure 33
shows the locations of the analog loops.
