Routing cables

Note

Note

3 Routing cablesThis chapter describes how to route antenna and transmission cables. Therequired cable kit shown in Table 1 accompanies the units in the BTS deliverypackage.

All cable illustrations show one possible path for connecting two ports. Theinstaller determines the exact route of the connecting cable.

3.1 Routing antenna cables

Figure 3 illustrates how to route antenna cables inside the cabinet from theantenna box to the front panel of the unit.

After you route cables, ensure all antenna cables are tied or secured to the cableretainer plates located in the right side of the cabinet.



Note

Routing cables

3.2 Routing transmission cables

The Transmission (VXxx) unit connects Nokia UltraSite EDGE BTS to the Abisinterface through one of the following media:

• radio-link

• wireline

• fibre-optic

Remove the VXxx unit cover to install the VXxx unit(s) and Abis cable(s), asshown in Figure 4. Route the Abis cable(s) through the EMC sleeve.



Note

Figure 4. Route of the Abis cable with VXxx unit cover removed

An E1/T1 adapter cable (RJ48 to TQ) is available to connect the Abis cable to theTransmission units (except for FXC E1 and FC E1/T1 units when using the 75 ΩE1). To order the adapter cable, contact your local Nokia representative.

3.2.1 Routing Flexbus cables to radio transmission units

The FXC RRI transmission unit contains two Flexbus interfaces for connectingto Nokia FlexiHopper or Nokia MetroHopper outdoor units, or to some otherindoor radio unit.

Routing cables

To route the RX/TX Flexbus cable:

1. Connect the RX/TX Flexbus cable to the TNC connector on the FXC RR1transmission unit.

2. Tighten the connector nut.

Figure 5 illustrates how to route Flexbus cables to the FXC RRI unit.

Figure 5. Routing the Flexbus cable to FXC RRI unit

3.2.2 Routing cables to wireline transmission units

This section describes cables for wireline transmission units available with NokiaUltraSite EDGE BTS.

FC E1/T1 unit

The FC E1/T1 unit has the following cables:

• one coaxial 75 Ω TX/RX connector for E1 use

• one twisted pair 120/100 Ω TX/RX interface connector for either E1 or T1use

Caution

Caution

Caution

Use either separate 75 Ω RX and TX connectors (BT-43) or one 120/100 ΩTX/RX connector (TQ).

The 75 Ω TX is grounded only when the grounding bridge between the TX andRX connectors is in place (see Figure 6).

If you remove the grounding bridge, the grounding of the RX connector’s outerconductor changes from direct grounding to capacitive.

To route cables to the 75 Ω connector on the FC E1/T1 unit:

1. If necessary, remove the grounding bridge with a 10 mm spanner (wrench).

2. Connect the RX cable to the 75 Ω RX connector on the front of the FCE1/T1 unit.

3. Connect the TX cable to the 75 Ω TX connector on the front of the FCE1/T1 unit.


To route cables to the 120/100 Ω connector on the FC E1/T1 unit:

1. Connect the TX/RX cable to the 120/100 Ω TX/RX connector on the frontof the FC E1/T1 unit.


Figure 6 illustrates how to route the cables to the FC E1/T1 unit.

The FXC E1 unit has four pairs of 75 Ω connectors (BT-43) for E1 use.

The 75 Ω TX is grounded only when the grounding bridge between the TX andRX connectors is in place (see Figure 7).

If you remove the grounding bridge, the grounding of the RX connector’s outerconductor changes from direct grounding to capacitive.

3. Connect the TX cable to the 75 Ω TX connector on IF1.

4. Repeat steps 1 to 3 to connect the remaining IFs (see Figure 7).

Configuration and combining options

Caution

4 Configuration and combining optionsThis chapter describes the combining options supported in Nokia UltraSite BTSand links them with the cable kits that come with the units in the BTS deliverypackage. Some common cabinet configurations are also illustrated.

Nokia requires that only properly trained and authorised personnel performinstallation, cabling, commissioning, and maintenance operations on any NokiaBTS.

Combining options

Nokia UltraSite EDGE BTS supports various combining options. You canconfigure Nokia UltraSite EDGE BTS in the following ways:

• Combining Bypass: no signal combining is used.

• Wideband Combining (WBC)

- 2-Way WBC – Signals from two TSxx units are combined into oneantenna using one WCxA unit.

- 4-Way WBC – Signals from four TSxx units are combined into oneantenna using two parallel WCxA units in series and a single WCxAunit.

• Remote Tune Combining (RTC)

- Signals from six TSxx units combine into one antenna with oneRTxx unit.

- Signals from twelve TSxx units combine into two antennas (aseparate antenna for RX diversity is unnecessary). Two RTxx unitsare needed.

• Dual Band Combining (GSM 800/1900 or 900/1800 in the same cabinet)

- Use any WBC or RTC combining option within each band.- DU2x combines RX/TX signals into one antenna (optional).

• Horizontal Sectoring (combining signals from different cabinets)



- Use any WBC or RTC combining option.

Cabinet configurations

To accomplish these combining options, Nokia UltraSite EDGE BTS supportsvarious cabinet configurations. The remainder of the chapter presents examplesof various cabinet combining configurations, including:

• 1+1+1, DVxx, Combining bypass, IBBU

• 2+2+2, DVxx, Combining bypass, IBBU

• 2-way WBC, 2-TSxx sector



• 2+2+2, DVxx, 2-way WBC, IBBU

• Midi 4+4+4, DVxx, 2-way WBC

• Midi 2+2+2, DVxx, Combining bypass




• 12+12+12, DVxx, 4-way WBC

• RTC, 6-TSxx sector

• 6+6+6, RTC, IBBU

• 6 Omni, RTC, IBBU

• Midi 6 Omni, RTC

• RTC, 12-TSxx sector

• 12+12+12, RTC

• 6+6+6, 2+2+2, Dual Band Combining without diversity

• 6+6+6, 2+2+2, Dual Band Combining with diversity

• 8+8+8, 4+4+4, Dual Band Combining

In this section, the cable routing illustrated in the figures is for reference only. Theinstaller determines routing during installation.

For information on installing units, see Unit Installation in this manual.

Terminate unused RX outputs and use dust caps for any unused antenna ports.

This section provides figures that illustrate cable connections and cabinetconfigurations for WBC.

4.2.1 2-Way Wideband Combining

With 2-way Wideband Combining (WBC), the WCxA unit combines the transmit(TX) signals from two Transceiver (TSxx) units and feeds the combined signal tothe antenna through the TX port of the Dual Variable Gain Duplex Filter (DVxx)unit.

A sector can have 2-way WBC and 2-way diversity with 2, 4, or 6 TSxx unitsectors.

Figure 12 illustrates the detailed cable connections for a 2-TSxx sector.

4.2.2 4-Way Wideband Combining

With 4-way Wideband Combining, the TX signals from four TSxx units arecombined using three WCxA units in the following manner. The first WCxA unitcombines the TX signals from two of the four TSxx units. The second WCxA unitcombines the TX signals from the other two TSxx units. The third WCxA unitcombines the two combined signals; then feeds the combined signal to theantenna through the TX port of the DVxx unit.

A sector can have 4-way WBC and dual variable gain duplex filtering with 4, 8,or 12 TSxx sectors.

4.4 Dual Band Combining

This section provides figures to illustrate cabinet configurations for Dual BandCombining.

A cabinet can use WBC or RTC when GSM 800/1900 or 900/1800 signals areboth present. (Combining bypass cannot be used.)
