Functional Description

Cabling Verification

Verify the following connections:
Perform the following verifications before inserting any cards in the COT shelf.
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 kΩ resistance between Tip and ground, and Ring and ground for each of
the HDSL pairs terminated at the FRE-765.
