synchronized to a DS1 facility and that the reference frequency provided by
the DS1 drifted beyond a range that could be tracked by the TN2182.
Therefore the TN2182 is no longer synchronized to that DS1 reference. If
a second DS1 is available, the tone-clock may be synchronized to that
reference. If no secondary DS1 reference is available, the tone-clock will
run off of its internal clock. This may result in slips being reported by the
tone-clock and every DS1 facility.
