VTR = The tip to ring voltage including the voltage across the
protection resistors.
ZL = The line impedance.
ZTR = The input impedance of the SLIC including the
protection resistors.
(AC) 4-Wire to 2-Wire Gain
The 4-wire to 2-wire gain is equal to VTR/VRX.
From Equation 21 and the relationship ZT = 200(ZTR-2RP).
Notice that the phase of the 4-wire to 2-wire signal is 180°out
of phase with the input signal.
(AC) 2-Wire to 4-Wire Gain
The 2-wire to 4-wire gain is equal to VTX/EG with VRX = 0
From Equation 18 with VRX = 0
Substituting Equation 24 into Equation 23 and simplifying.
By design, VTX = -VTX, therefore
A more useful form of the equation is rewritten in terms of
VTX/VTR. A voltage divider equation is written to convert
from EG to VTR as shown in Equation 27.
Rearranging Equation 27 in terms of EG, and substituting
into Equation 26 results in an equation for 2-wire to 4-wire
gain, that’s a function of the synthesized input impedance of
the SLIC (ZTR) and the protection resistors (RP).
Notice that the phase of the 2-wire to 4-wire signal is in
phase with the input signal.
(AC) 4-Wire to 4-Wire Gain
The 4-wire to 4-wire gain is equal to VTX/VRX, EG = 0.
From Equation 18.
Substituting -VTR/ZL into Equation 29 for IM results in
Equation 30.
