Figure 3. RJ45 Connector Wiring

3.2.2 Craft Interface Connection

SeRF front panel provides a craft port that can be used to provision remote units through the

optical protocol supported by a single RJ-45 connector. The Craft connector provides an

Ethernet interface.

Craft interface connection between the HU and the network is supported by a RJ-45 jack 10/

100Base-T (IEEE802.3 compliant) with integrated green ACTIVITY and LINK LEDs. The

Ethernet port supports a maximum cable length of 100 meters (328 feet) to a hub or back-to-

back nodes. CAT5 or better cable should be used when making this connection.

1. The IEEE Specification for Ethernet 100BaseT requires that two twisted pairs be used and that

one pair is connected to pins 1 and 2, and that the second pair is connected to pins 3 and 6.

2. Pinout information is shown in Table 1. See Figure 3 for RJ45 connector wiring

information.

3.2.3 Optical Interface

Optical connections between the HU SeRF card and the RU are supported through Small Form-

factor Pluggable (SFP) transceivers. The optical interfaces are standard single-mode duplex LC

(flat polished UPC). There are 8 duplex optical interfaces, one for each simulcast remote.

3.3 DART Card

The host DART provides the interface between base station equipment and the SeRF. It is a

band specific assembly and exists in the following versions:

• Cellular

•SMR 800

•SMR 900

•PCS

The following features and capabilities are available on the DART Card:

• Amplifies, down-converts, filters and digitizes from a 1.5MHz to 35MHz band of the

incoming RF signal
