Cut-Off
s
The transmit path and the receive path can be cut off at two locations each.
Figure 35
shows the locations in the signal paths.

Cut-Off
s in the Transmit and the Receive Paths
All Cut-offs disabled (Normal Operation).
COT16
Cut Off Transmit path at 16 kHz (input of TH-Filter).
COT8
Cut Off Transmit path at 8 kHz (shortens the input of the
compressor unit to ground, resulting in PCM idle codes in the
transmit time slot).
COR4M
Cut Off Receive path at 4 MHz (POFI-output).
COR64
Cut Off Receive path at 64 kHz (IM-filter input).
