Caution: Feeder connector cutting tool is very sharp. Take care while using cutting tool to avoid serious injury.



3. Feeder Cutting

i. Determine the main feeder length in each sector with a tape measure according to actual route.

ii. Use hacksaw to cut the feeder sufficient length. Usually add some margin about 1 ~ 2 m (4 ~ 7 feet) to measured lengths when cutting cables.

iii. Attach corresponding temporary labels (such as “RFE0-ANT0”, “RFE0-ANT1”, “RFE1-ANT0”, “RFE1-ANT1” and so on) at both main feeder ends after each cut. Attach formal labels after feeder installation.

iv. While feeder cutting, label its both ends and stick temporary labels to the feeder middle. Labels must be correct to get correct connections and sector matching.

NOTE: Labels are very important. Make sure all necessary labels are correctly and reliably stuck.

v. In roof installation, carry cut feeder cables to roof. And in tower installation, refer to “4. Hoisting Feeders to Tower” to take feeder cables to iron tower platform. In this procedure, ensure feeder cables in proper pressure and not damaged.

4. Hoisting Feeders to Tower

i. Wrap the main feeder connector made under the tower with flax (or antistatic packing bag together with foam) and strap it tightly.

ii. Knot and fix the cut feeder cable with hoisting rope at two points. One is 0.4 m (1 5/16 feet) away from the feeder connector and the other is 3.4 m (11 2/16 feet) away. Employees must cooperate to hoist feeder cables to avoid feeder and its connector from colliding with the iron tower.

iii. After hoisting main feeder cables to the tower top, fix upper end of cable at multiple points to prevent it from slipping down the tower.

Take care for personnel safety when hoisting the feeders.

5. Connect Feeder and Antenna Jumper

i. Fix the main feeder cable connector and antenna jumper.

ii. To ensure feeder cable performance, seal connectors with waterproof self-adhesive tape and PVC tape.

6. Fixing Feeder Cables

Determine the path of feeder cables while reaching an agreement with owner to avoid any disturbance in future. Satisfy the following requirements during fixing the feeder cables.



Fix the feeder cables neatly without crossing with each other, especially in the part of entering equipment room and on indoor cabling rack.

Make the route clear before fixing feeder cables. It is recommended to note down feeder actual route on paper to avoid rework for crossed feeder cables.

The minimum bending radius of the main feeder cable can not be less than 20 times the radius of the main feeder cable.

As to 1/2” jumper, the minimum single-bending radius is 80 mm (3 inches), and the minimum multi-bending radius is 125 mm (5 inches). The cable can not be bent more than 15 times.



Maximum spacing between 3-feeder clips:

As to 1/2” feeder cable, the maximum space is 1 m (3 4/16 feet);

As to 7/8” and 5/4” feeder cable, the maximum space is 1.5 m (5 feet);

In any case, the maximum space between 3-feeder clips can not be more than 1.65 m (5 7/16 feet).

When the wind speed of CBTS I2 site is often over 160 km/h (100 miles/h), reduce the spacing between feeder clips properly.

Here is an example of fixing 7/8” feeder cable. Perform this procedure to fix the feeder cable:

i. Follow above requirements to install 3-feeder clips.

Note: Keep spacing as even as possible and ensure feeder clips installation direction same. While installing two rows of feeder clips inside same cabling ladder or cabling rack, keep the two rows parallel and arrange them neatly.

ii. Sort the feeder cables in order.

iii. Fix the main feeder cables from top to bottom and sort them into 3-feeder clips. Fasten the feeder clips after smoothing the main feeder cables. Keep main feeders flat and straight. It is not permitted to fix feeder cables in both ends at same time.

iv. Fix the main feeder cables with 3-feeder clips along the outdoor cabling ladder or the cabling rack to enter equipment room.

7. Installing Feeder Grounding Clips

Ensure these grounding requirements while installing feeder grounding clips:

Roof installation mode

In roof installation, the following items must be grounded to building grounding network:

Main antennas system

Antenna pole

Outdoor cabling rack or cabling ladder

Ground the main feeder cable at two positions:



Where it leaves antenna pole

Where it enters equipment room

If the feeder cable is rather long, add grounding points according to feeder length.

Tower installation mode

Usually at least three feeder grounding clips are required to be installed in tower installation mode. Ground the feeder cable at the following positions:

Where it leaves antenna installation pole

Where it leaves iron tower

Where it enters equipment room.

When feeder cable is longer than 60 m (197 feet), then install a grounding clip on the feeder cable after every 20 m (66 feet) distance.

If outdoor cabling rack or outdoor cabling ladder is used, ground it reliably.

Antenna poles and iron tower need to be grounded reliably.

In tower installation mode, grounding cable is installed downwards and finally connected to tower;

In roof installation mode, grounding cable is installed in the same direction with feeder cables.

v. Make joint of grounding clip and feeder waterproof using waterproof adhesive tapes, then use insulation tapes to cover the joint.

vi. Connect the grounding end of the grounding clip to the grounding network.

Connect it to the main tower body in tower installation mode.

Connect it to the grounded cabling rack in roof installation mode.

When connecting, remove the paint and oxide at connection place within a radius of 13 mm (8/16 inches) around the joint, and daub the place with antioxidant cream to ensure good electric contact. After connecting, paint the joint with anticorrosive paint.

Caution: Do not install grounding clip in case of any lightning strike.

8. Routing Feeders into Equipment Room

Following are the feeder entering requirements:

Use cabling racks both indoors and outdoors to guide the feeder cables.



Make proper arrangement to avoid rain from flowing into the equipment room through feeders. It is required to route feeder cable in the shape of a bow, as is shown in Figure 81 and Figure 82.

i. Loosen the sealing fixture hoop in the feeder window to a proper degree. Remove the holes covers to run the feeder cables through.

ii. Lead the feeder cables into equipment room.



Two employees are required to stay inside and outside equipment room respectively to cooperate to lead the feeders into equipment room so as to avoid damage to the indoor equipment and hurt to the feeder sheath. Fasten the fixing hoop after pulling the feeders in place.

iii. Measure the required length of feeder cable precisely and cut feeder cables with hacksaw.

Select the cut point according to cabinet position, cabinet jumper length, lightning arrester configuration and lightning arrester position, and take feeder cable bending restriction and equipment room neatness requirement into consideration.

Ensure that the temporary labels on the feeders are complete before and after feeder cutting.

iv. Make the indoor connectors for main feeder cables.

v. Use 3-feeder clips to fix main feeder cables onto indoor cabling rack in proper spacing.

END OF STEPS.



Lightning Arrester Installation

Perform this procedure to install lightning arrester.

Broadband lightning arrester does not need independent grounding system. It is placed between main feeder cables and indoor cabinet jumper.

Lightning arresters that need grounding system must be grounded with 12×M6 copper bar. Adjust each feeder cable to ensure that feeder connector is connected with lightning arrester reliably.

Figure 83 illustrates widely used grounding lightning arrester.

VSWR Test After installing all antenna feeders and jumpers, conduct SWR test. The SWR must be less than 1.5. Otherwise, check all main antenna and feeder system, including:

Feeder connecter

antenna and jumpers

whether the sheath is broken

whether the bending radius is too small

whether the lightning arresters are not installed properly

Adjust until VSWR is less than 1.5.

Waterproofing Joints Perform this procedure to seal joints between feeder and jumper. It is an example for waterproofing all kinds of joints.

The 1/2'' jumper and the main feeder are connected.

Seal 1/2'' jumper and feeder connectors for waterproof treatment as follows:

1. Wrap one layer of insulation tape to feeder and jumper connectors. Cover the lower layer with upper layer about 1/2. The tape coverage is required to be 10 mm (6/16 inches) longer than connector tails. When wrapping, pull the tape with enough strength.

2. Wrap waterproof adhesive tapes from lower position of connectors and fill the lower-lying parts of the connectors, is as shown in Figure 91.

F I G U R E 91 - W R AP P I N G W AT E R P R O O F AD H E S I V E T AP E S (1 )

GPS Antenna Feeder System Installation with 1/4” cables Most of the installation is similar to the main antenna feeder system. So in the following sections, only some key installation steps are introduced.

Prepare 1/4” Feeder Cable N-model Connector

Perform this procedure to prepare 1/4” feeder cable N-model connectors.

It is suggested to prepare following tools:

A ruler with minimum scale of 1 mm ( or 1/16 inches);

Paper knife;

Wrench;

A file;

A brush.

If a feeder connector knife is equipped, it will be much easier to prepare a connector.

Important! 1/4” cable’s copper bellow is thin and easy to be broken. So in engineering field, it is forbidden to stand on the 1/4” cables. And other operations which are probable to damage 1/4” cables are forbidden, too.

2. Use paper knife to cut the external conductor of feeder cable. Figure 100 illustrates the position to cut external conductor.

Steps



NOTE:

i. The cut position is just 14.5 mm (9/16 inches) away from the cable sheath edge. (The metric measure value is the exact value, and there are small errors in the British measure value.)

ii. Ensure that the cut position is just on the wave crest of a feeder corrugation.

iii. If the above two requirement can not be satisfied simultaneously, measure and adjust the cable sheath edge’s position until two requirements are both satisfied.

3. Use a file to file the inner conductor gently, and make it satisfy the requirement of “0.3×45°”. “0.3×45°” means:

File the top of the external conductor flat and smooth. And the length of the stuck-out inner conductor must be 5.5 mm (21/97 inches);

File a slope at the edge of inner conductor’s top. Ensure the angle between the slope and the inner conductor just



45°, and the inner conductor length corresponding to the slope is 0.3 mm (1/85 inches).

Ensure that no burr is on the surface of inner conductor. If any burr exists on the surface, the GPS signal quality will reduce a lot.

Appendix B

Compact BDS Module (CBM)

This Appendix describes the following topics:

Salient features of CBM

CBTS I2 configuration with CBM.



Salient Features A single Compact BDS Module (CBM) replaces CCM, CHM, RIM, RMM, GCM, and DSM. A single CBM board can provide all the functions of BDS subsystem (except SAM and BIM), and that of RIM board. However, configuration supported by the CBTS I2 with CBM board is less as compared to CBTS I2 without CBM board.

CBM board performs the following functions:

Provide functions of GCM board, such as receives and process the GPS signal. At the front panel of CBM board, there is an interface for connecting with GPS antenna. In addition, there are two test interfaces at the front panel of CBM board for PP2S and 10 MHz clock respectively.

Provide functions of DSM board, such as it provides eight E1/T1 interfaces, and process the Abis data from 8 E1/T1 interfaces.

Provide functions of CHM board, such as performing baseband modulation and demodulation, diversity, etc. With typical configuration a single CBM board supports 6 Carrier-Sector 1X configuration. With extended configuration (either CEB5 (6700) or CEB4 (6800)), a single CBM board can support 12 Carrier-Sector 1X configuration (Using CEB5 (6700) Sub-card), or can support 6 Carrier-Sector 1X configuration and 3 Carrier-Sector DO configuration (Using CEB4 (6800) Sub-card).

Provide functions of RMM board, such as Local RFS centralized control, including a TRX module, a PA module and a RFE module. It provides six interfaces to connect with TRX boards. In addition, it collects all the alarm information from PIM module.

Provide functions of RIM board, such as it provides three fiber interfaces to connect with RRFS. Like RIM board, these fiber interfaces are located at the front panel of CBM board.

Provide functions of CCM board, such as controlling the entire CBTS I2, communicating with OMC, etc.

CBTS I2 with CBM does not support extended cabinet configuration.

CBM board does not support 1+1 backup.

CBM board does not support Abis fiber links.

Appendix A Compact BDS Module (CBM)


CBTS I2 Configuration with CBM

Figure 126 shows the typical CBTS I2 configuration when CBM board is used in place of CCM, CHM, RIM, RMM, GCM, and DSM.

F I G U R E 126 TY P I C AL C O N F I G U R AT I O N

Note: The Type of SAM board is SAM3, and Type of BIM board is BIM7-E.

The description of CBTS I2 with CBM is as follows:

CBM board is plugged in to slot earlier used for RMM board. CBM board does not support backup. There is one fan in lower row under the CBM as compared to earlier CBTS I2 because the right part of baseband frame has no board.

CBM board has a DB44 interface connected with BIM board DB44 interface via internal cable. Figure 127 illustrates this scenario.

Typical Configuration

Description



F I G U R E 127 IN T E R N AL E1 /T1 C O N N E C T I O N

1. DB44 Interface 2. Internal Cable

When CBTS I2 is configured with CBM, one fan is reduced.

The power consumed by CBTS I2 with CBM is 150 W less when compared with power consumption of CBTS I2 without CBM.

To enhance the baseband resources and Carrier-Sector configuration, additional sub-cards can be installed on CBM board.

Either CEB5 (6700) or CEB4 (6800) can be added to CBM board. One CEB5 Sub-card can support 6 Carrier-Sector 1X service, while one CEB4 sub-card can support 3 carrier-sector DO service.

To support RRFS, add OIB2 sub-card. A single OIB2 sub-card supports three pairs of fiber. Figure 128 shows a maximum RRFS configuration.

CBTS I2 with CBM provides GPS interface that connects with GPS antenna. Figure 129 illustrates this connection.

1. Lightening Arrester

CBTS I2 with CBM does not support extended cabinet configuration, so EXT_BDS, S_FE1, M_FE1, S_FE0, M_FE0, EXT_MON, M_TEST, and S_TEST interfaces are not used. Moreover, CBM support 8 E1/T1 Abis interface, so BSC_E1_G1 is not used. In addition, CBM support the BSC_FE interface. The functions of all other interfaces are same as CBTS I2 without CBM board.

Description System features

LS Local single mode Supports 4C3S (1X/DO) and most cost effective

RS Remote single mode

Supports 4C3S (1X/DO)

LEA Local extended mode A

This mode use two rack configuration with single BDS rack. It supports up to 24 CS (1X) or 12 CS (DO)

LEB Local extended mode B

This mode uses two BDS rack configuration. It supports up to 48 CS (1X) or 24 CS (DO)

RE Remote extended mode

Use optical fiber to enable remote extension RRFS. It supports up to 24 CS (1X) or 12 CS (DO)

ME Mix extended mode This mode extends RFS/BDS in local side and extends RFS in remote side with optical fiber. It supports 24 CS for EV-DO and 48 CS for 1X. Uses optical fiber to enable remote extension, remote side can be CBTS I2 and MBTS-RFS.

Note: Installation in LS mode is described before.

Cabling Following section introduces cabling for remaining five modes.

In RS mode, baseband module is not needed in remote CBTS I2. Insert optical fibre from baseband side into RMM board on remote CBTS I2.

In RE mode, CBTS I2 is primary base station. Upon completion of other equipments, it is only needed to lead an optical fibre out from RIM board. Then lead optical fibre to remote RF module via transmission device.

LEA refers to extension of CBTS I2 RF module. Use optical fibre to connect RIM on primary CBTS I2 and RMM on extended CBTS
