Input Gain

The telephone input gain has a range from -20 to +20 dB for adjusting the gain
in the analog domain and has a default gain of 0 dB. The gain required will
depend on the signal levels received from the telephone line. Adjust the tele-
phone gain so that during normal speech there are at least two yellow LEDs lit
on the telco receive.
