Step 10 Backhaul Connections (Iub) to INC
The backhaul connections can be selected from the following interfaces
 100BaseT
 E3/T3

E1/T1
The connections are labeled and shown in the figure below. To install any of the cables remove
the blanking plug in the appropriate position to align with the interface selected. The cable gland
to seal plus strain relief the cable is as illustrated for the power connection above.
Note: If the Node B is in not in the same site location as the serving INC, there must be no
greater than a 5 millisecond delay on the backhaul connection. This can be provided by
microwave or land based facilities with a very high reliability rate of 99.9995%.

Feed the cables through the cables glands external from the enclosure before feeding the cable
through the appropriate gland hole at the base of the Node B.
Terminate the Ethernet cables with RJ45 connectors and secure the cable gland to the Node B.
Test the continuity for the Ethernet cables with test equipment consisting of a main and a remote
unit.
The termination for these interfaces is specified within the datasheets for the interfaces. The
specification for both cables should be CAT5 - 4 pair, screened cable, recommended Alcatel
LANmark-5 F2TP or equivalent.
