inserted in the COT shelf.

a. Verify that there is between -42 V dc and -56 V dc between the –48 V dc

and GND screw terminals on the COT shelf.

orientation.

Note: If the HDSL lines are not connected properly, the COT will not

communicate with the RT.

c. Verify that the HDSL lines are "dry":

1) There should be 0 V dc between the tip and ring, tip and ground, and

ring and ground of each of the HDSL circuits terminated on the shelf.

2) There should be > 100 kohm resistance between the tip and ring, tip
