ATU-C Side Block Diagram
The transformer at the ATU-C side has a 1:2 ratio. The termination resistors are 12.5
in case of 100
lines. The hybrid bridge resistors should be < 2.5 k
for low-noise.
An HP filter must be used on the TX path to reduce DMT sidelobes and out-of-band noise influence on the
receiver.
On the RX path, a LP filter must be used in order to reduce the echo signal level and to avoid saturation
of the input stage of the receiver.
The POTS filter is used in both directions to reduce crosstalk between ADSL signals and POTS speech
and signalling.
