Backplanes

This handles all the interconnect to the units modules and additionally in the Quantro discrete interconnects to the IPA which are behind the PA.

The Telco 50 pin is used for interfacing most of the Wireline and IO, I typically use a punch down block for this, as it provides an easy way to test and a clean looking hookup.

Note the Quantro has two connecotrs on the front station side of the board which are typically used by the PA interconnects, you have to reach in and connected these from the back of the unit next to the IPA module.
