HRE-454
The HTC-400 extends beyond the front plane of the shelf or enclosure into which it is inserted. This permits easy
access to the test points. However, this limited extension is such that the HTC-400 could be inserted into the
HRE-454 outdoor enclosure with the card cage retaining/locking bar in place. This allows the HTC-400 to be
permanently installed in any slot where it provides loop-through of the cable pairs. This allows end-to-end metallic
cut-through access to Sides 1 and 2 cable pairs without the need to rewire the shelf slots.
