Note:
1. Resistors are 1%, 0.1Watt; Unless stated, capacitors are 5%, 6.3 V.
2. All diodes in the circuit are 1N4148 or equivalent.
3. Xtal is 3.579545 MHz, 0.1% crystal or ceramic resonator.
4. Tip/Ring op amp gain = 0 dB; Hybrid Receive op amp gain = -3 dB.
5. For 1000 Vrms, 60 Hz isolation from Tip to Earth and Ring to Earth:
R1, R2 = 430 k, 0.5 W, 5%, 500 V min.
C1, C2 = 2n2, 250 V min.
6. For BT application, R3=R4= 422k;
For Bellcore application, R3=825k, R4=226k.
