0 dBm0, D_R0 or D_R1 = 0 dBm0 PCM code. Transmit and receive gains programmed for maximum 0 dBm0 test levels (0 dB
gain), hybrid balance filter disabled. All other limits are assured by correlation with other production tests and/or product de-
sign and characterization. All signals referenced to GND. Typicals specified at V_CC = +5V, V_BB = −5V, T_A = 25˚C.
