Cabling Verification. 

Verify the following connections:

1

Visually ensure that the ground wire is tightly secured to the grounding lug inside the FRE-765 and at the 
ground termination point.

2

Visually verify that the HDSL lines are terminated properly and with the correct orientation.  If the HDSL 
lines are not connected properly, the COT will not communicate with the FRE-765.

3

Verify that the HDSL lines are "dry."

a

Verify 0 Vdc between the Tip and Ring, Tip and ground, and Ring and ground of each of the HDSL pairs 
terminated at the FRE-765.

b

Verify a value greater than 100 k

 resistance between Tip and ground, and Ring and ground for each of 

the HDSL pairs terminated at the FRE-765.
