OTE: Parameters expressed in dBm0 refer to
signals at the telephone line, i.e., across
R2 in Figure 1. All units in dBm0 are
measured at the line input to the
transformer.
The
(Figure 1) inserts an 8 dB loss in the
transmit path (TXA1 - TXA2 to line), and
a 3 dB loss in the receive path (line to
RXA).
