[c-nsp] Lab setup

[Clinton Work]

You can connect the cards back to back and they should work fine.  Just 
a couple of notes:

a) Set both POS interfaces to "clock source internal" because there is 
no network clock  in a back to back configuration.
b) Looks like the POM-OC3-MM and POM-OC3-SMIR optics are safe in a back 
to back configuration without optical pads.  If you using the 
POM-OC3-SMLR you will need at least 10db pads on a short fiber patch.  
c) Make sure you to cross over the transit/receive on the back to back 
fibers patch cables. 

Clinton.
