cabling is shown in Figure 16. Note that the transmit signal is somewhat
attenuated in order to meet the launch amplitude specified by the
standards. The external receive circuitry is designed to attenuate low
frequencies in order to compensate for the high frequency attenuation of
the cable.

receive false signals in the absence of a real signal. This can be important
because the 77V106L25 does not disable error detection or interrupts
when an input signal is not present.
