Cabling Overview

Overview

Configurations Supported

This chapter provides the procedures to prepare the BTS site cabling, but not attach it to the unit. Chapter 6 shows the scope of work for unit cabling.

You will connect cables to the site and route them to the BTS location. You will attach the cables to the unit in Chapter 6.

Repeat cabling installation as necessary for each unit at the BTS.

NOTE

Cabling is one of the most noticeable aspects of workmanship. Straight runs and proper turns are critical for a positive evaluation of the work.

Power, Ground, and Battery Cabling for Sites Equipped with Customer–Supplied Site I/O Interface

Objective

The objective of this procedure is to install the power, earth ground, and battery cabling for one or more Microcell units at a site equipped with customer–supplied Site I/O Interface.

WARNING

Dangerous voltages, capable of causing death, are present in this equipment. Use extreme caution when handling and testing this equipment.

NOTE

If you are installing the unit outdoors and are not using the Primary Surge Suppressor, then you must connect AC power with the AC Installation Box. The AC Installation Box is included with the non–surge option.

Other Grounding Considerations

This procedure covers only the grounding information for the cables that attach to one or more MicroCell units. Grounding considerations beyond the ground cables that attach to the MicroCell are summarized in Appendix A. Refer to Appendix A and the site documentation for other grounding considerations.

NOTE

Motorola recommends that you use an oxide inhibitor such as Burndy PENETROX or Ilsco DE–OX on all the external ground connections on the unit and on the site I/O interface for all outdoor installations. This includes the ground connections on the mounting bracket, the Site I/O, and the lugs on the customer–supplied site I/O interface.

Power Requirements and Configurations

The power requirements for each unit is: 120–240 VAC (7.5 amps min.) or 20–30 VDC (20 amps min.) power input.

4-10

The AC Installation Box is required for all outdoor installations which use the customer–supplied Site I/O interface.

The customer–supplied site I/O interface must be able to pass the 4kV/6kV transient impulse test (Motorola 12M09154A49 Sec. 3.5.3.2.1: Impulse Surge, Test Condition A).

with the Primary Surge Suppressor.

The Site I/O interface and cabling are customer–supplied. The cable between the Site I/O junction box and the Site I/O interface is part of the Site I/O junction box and is supplied by Motorola. If your BTS uses the customer–supplied Site I/O Interface instead of the Primary Surge Suppressor, then you will need to use the Site I/O Extender Cable (Cable Z). The Site I/O Extender cable is included with this option.

4-18

The customer determines the Site I/O interface configuration. The end result is the correct signals getting to the correct pins on the Site I/O cable.

RGPS Cabling for Multiple BTS Sites

Objective

This procedure gives information to connect multiple BTS sites for both RGPS (synchronous) and HSO (non–synchronous) configurations in both indoor and outdoor applications.

Background

The RGPS only connects to the first unit of a multi–unit logical BTS. This first unit sends timing signals to all other units. You only need to connect the site I/O interfaces of each multi–unit logical BTS to each other. This allows “sharing” of a single RGPS antenna between several single or multi–unit logical BTSs.

This also applies to systems using HSO instead of RGPS. The HSO timing is “shared” in the same way.

Required T ools and Equipment

Cables

Surge suppressors (Polyphaser 097–1017A–A.1) are required for certain installations.

Cable Diagrams and Description

Figure 4-18 shows the RGPS cabling for a multi–BTS configuration for an RGPS (synchronous) configuration. Figure 4-19 shows the RGPS cabling for a multi–BTS HSO (non–synchronous) configuration.

Figure 4-14 shows the general construction of the RGPS Sync Cable (cable X). Cable X is supplied by Motorola with a 7.5 k Ohm, 1W resistor already installed 150 mm from the end of the cable on the blue/black wire. There is 200 mm on each end of the cable where the jacketing has been cut back.

If necessary, the jacketing of cable X may be cut back further for proper strain relief. For installations that require surge protection, you may cut cable X at the dashed lines and insert the surge protection devices. Refer to Table 4-29 for instructions to install the RGPS with surge protection.

In cases where it is impossible or impractical to route cable X in a continuous stretch from BTS N to BTS N+1, you may cut and rejoin the cable using an inline splice (solder or crimp). Both types of connections are acceptable as long as each wire remains electrically isolated from every other wire. The twisted pairs must be kept together. Refer to Table 4-30 for the pairing of the twisted pairs.

RGPS Cabling for Multiple BTS Sites Equipped with Optional Primary Surge Suppressor

Objective

This procedure gives information to connect multiple BTS sites for both RGPS (synchronous) and HSO (non–synchronous) configurations in both indoor and outdoor applications.

Background

The RGPS connects to the site I/O interface of a multi–unit logical BTS. This first unit sends timing signals to all other units in a multi–unit logical BTS. You only need to connect the site I/O interfaces of each BTS to each other. This allows “sharing” of a single RGPS antenna between several single or multi–unit logical BTSs.

This also applies to systems using HSO instead of RGPS. The HSO timing is “shared” in the same way.
