Ground :
This is the ground pin for the
speech network.
GND for REC/PLY,
VREG, SPEECH and
LINK
Line power input:
Connects to the positive out-
put of the diode bridge.
Side-tone adjustment:
Grounded through R1 (27
)
Connects to the side-tone
adjusting circuit to adjust side
tone and receiver level.
Line voltage control (1) :
Int. ref. voltage output (2) :
Output impedance=50
Int. ref. voltage output (1) :
Outputs half the Vreg reference
voltage.
Trans. preamp. output :
C7 as connected between this
pin and the ground forms a
low-pass filter.
