In this document, the cable color and equipment appearance is for reference only. The actual cables and equipment may differ from what are shown in the figures.

Attach labels before routing cables.When cutting the BTS3900L input power cable, reserve an extra length of 300 mm. Add an OT terminal to the

cable on site.

Fan boxE1 cable or FE cable can be configured according to the transmission

mode of the base station. Only one transmission mode is supported by the base station working in the GSM standard, and two transmission modes can be supported by the base station working in the UMTS standard. For details about the configurations and cable connections, see the BTS3900 Hardware Description.

For a multi-mode base station, only SRAN5.0 supports the LTE mode.

Installing Transmission Cables

Installing the E1 Cablea

Ensure that both ends of the E1 cable are disconnected. Then, weld connectors to the bare wires at one end of the E1 cable all at once.

Color RingSectorSystem

Attach color rings by referring to the following table.

If main and diversity are not distinguished, the RF signals transmitted from the left RF unit are regarded as the main signals by default, and the RF signals transmitted from the right RF unit are regarded as the diversity signals.

If an antenna system serves six sectors, the colors of the rings for sectors 4, 5, and 6 are purple, orange, and green respectively.

Insulating tape

The waterproof tape should be wrapped for an extra length of 20 mm away from the connectors at both ends.

The tapes should be wrapped around the connector from the lower part to the upper part. When wrapped for another layer, the tapes may not be cut.

When wrapping the waterproof tape, ensure that the upper layer of the tape covers at least 50% of the lower layer.

The insulating tape should be wrapped for an extra length of 20 mm away from the waterproof tapes at both ends.
