  • Page 24: Cabling Verification

    Verify the following connections: Perform the following verifications before inserting any cards in the COT shelf. Visually ensure that the ground wire is tightly secured to the grounding lug inside the FRE-765 and at the ground termination point. 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.
