User's Manual

The recommendations for NIU conduit are as follows:
• The rigid NIU conduit must be installed from the NIU to the 9927 Distributed Base
Station Outdoor Cabinet.
• Use PVC conduit instead of rigid NIU conduit if it is to be buried. Use metal conduit
if it is to be exposed. The NIU end of the conduit must be bonded if it is metallic.
Flexible T1/E1 conduit is also required. It is the responsibility of the customer to provide
flexible conduit and all required connectors and fittings, and to hold them for the installer.
See “Conduit requirements” (p. 5-7) for specifications for the required conduits.
Route the T1/E1 and User Alarm cables through the conduits
After the T1/E1 and User Alarm cables have been connected to the NIU, and the conduits
have been installed, the T1/E1 and User Alarm cables must be routed through the NIU
conduit, and coiled approximately 6 meters (20 ft.) at the end of the conduit.
To prevent damage to the twisted-pair cable inside the conduit, the conduit end must be
properly protected against the environment, rodents, and other interferences. This can be
done by stuffing the twisted-pair cable into the conduit, and capping the end of the
conduit.
