Pssst - don't tell anyone, but if you have a dual T1/E1 box, if =
you have a clock source on line 0, line 1 will use the incoming =
signal on line 0 as the transmit clock source on line 1.

I haven't been able to prove this, since I do not have a PM3, but =
it sure looks like it behaves in this manner. I have brought this =
to LE's attention, but have not heard anything back from them.
