Figure 146
Ground start call connection sequence - incoming call from CO/FX/WATS
If the threshold count exceeds its limit, an error message is printed and
the trunk is registered as "positively reverse wired." Once identified as
positively reverse wired, the call is presented continuously from the
first ring. When a reverse-wired trunk becomes correctly wired, the first
subsequent call clears the threshold counter and normal ground start
processing is implemented.
