Long day, but in the end I got it all working. Here is what I did wrong...

I forgot about setting the bank of 4 dipswitches to 1&2 On and 3&4 Off on the T1/PRI combo card when using as PRI.

The T1/PRI card worked fine in Cabinet 1 as currently poplulated. Had to set the LMU1 switch in Cabinet 0 to down position (PRI). Mandatory when installing T1/PRI combo in cabinet other than 0.

No clocking wires needed for Point-to-point. Just set Hub to clock off and Node to clock on.

When networking systems with a Telco point-to-point, the hub definately needs a T1 cross-over cable between it and the CSU/Telco. The node is straight-thru.
