1000BaseT Connection - (Eth)

Terminate the Ethernet cables with RJ45 connectors and the cables may be secured to the

brackets on the face of the Control Shelf (

Figure 5-13). 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.

Notes:

Points to remember when installing Category 5 cables for the Node B 1000Base T

Ethernet Backhaul.

1. Do not kink the cable as the pairs are twisted to support 100MHz operation and splitting the

pairs could reduce the performance of the cable.

2. When installing the RJ45 plugs onto the cable ensure pairs are untwisted to the minimum

and that the cable sheath is clamped within the connector. Again this is to ensure the

performance of the cable is not reduced.

The pin-outs for the external Ethernet interfaces are given in the following table & figure.
