... The suppression also depends on the accuracy of the match between Z line. The anti-sidetone network for the UBA1706 (see Fig.15) ) attenuates the receiving signal from the line before it enters the receiving amplifier. The attenuation is almost constant over the whole audio frequency range. ...

... PIN RAGC2, SAGC AGC) AND The UBA1706 performs automatic line loss compensation. The AGC varies the gain of the transmit amplifier and the gain of the receive amplifier in accordance with the DC line current. The control range is 6.5 dB (which corresponds roughly to a line length of 5.5 km for a 0.5 mm diameter twisted-pair copper cable with a DC resistance of 176 /km and an average attenuation of 1 ...
