Ground Connections
¢
In Central Office:
There should be a CO GND that is adequately grounded. If the measured resistance
from the grounding screw (on the rear panel of the DSLAM, refer to below figure)
to CO GND is less than 5 Ohm, then it can be assumed that the system is well
grounded. If the measured resistance is larger than 5 Ohm, it is recommended
to connect the grounding screw to CO GND using #14 or #12 AWG wire gauge
conductor.
¢
In Remote Cabinet:
The IDL-4802 should be grounded by connecting a #14 or #12 AWG conductor
between the grounding screw (on the rear panel of the DSLAM, refer to below
figure) and the earth ground or main grounding bar. The resistance between the
chassis and the grounding bar should be less than 25 Ohm.

Ensure that all power sources to the device are turned off during
the installation.
