User-Programmable Components Where ZT is connected between the VTX and RSN pins. The fuse resistors are RF, and Z2WIN is the desired 2-wire AC input impedance. When computing ZT, the internal current amplifier pole and any external stray capacitance between VTX and RSN must be taken into account. Where ZRX is connected from VRX to the RSN pin, ZT is defined above, G42L is the desired receive gain, and ZL is the 2-wire load impedance. Where RDC1, RDC2, and CDC form the network CDC = (1.5 ms)(RDC1 + RDC2)/(RDC1 • RDC2) connected to the RDC pin. RDC1 and RDC2 are approximately equal. Where RD and CD form the network connected from RD to –5V and IT is the threshold current between on hook and off hook.
