Transformer driver A, used to drive the transformer of the
electrical interface. For E4 operation, this output should be
connected per Figure 19 to provide the correct G.703 compatible
output levels from the transformer when connected to the
specified 75Ω cable.
XFRMDRVB
Transformer driver B, used to drive the monitor transformer of
the electrical interface. This output should be connected per
Figure 20 to provide the correct output levels from the
transformer when connected to the specified 75Ω cable.
