Tx ABCD BITS
The Transmit ABCD bit parameter has two options:
mon
(allowing you to observe the bit
pattern being sent on the transmit side of the line), and
set
(to choose a different pattern for
testing that portion of the circuit). Choosing
set
brings up a small four-character window at
the bottom of the screen, where you can type in a new pattern of ones and zeros.
Figure 4-43 shows a diagram of the test process. When Tx ABCD for w2-1 is set to
mon
, the
w2-1 column reflects the ABCD bits being sent out on w2-1. This pattern should be identical
to Rx ABCD on w2-2, unless the conversion table is used. When Tx ABCD for w2-1 is
