If the NT1 indicators are not as shown above, it is not ready for use with
the M5209; contact your supervisor for direction.
Once you have checked the cable connections and power supply, and
the M5209 is still not responding:
8
Unplug the RJ45 line cord from the wall jack or TR box for five
seconds, then plug it back in and perform a power reset on the M5209.
9 If problems still exist, try another M5209T set, using the existing
cables. If this set works, the problem is with the original set; it should
be replaced.
If the replacement M5209T does not work, replace the existing cables
with your spare cables; repeat step 8.
If problems persist, contact your supervisor.
