2.1.4 Electromagnetic Radiation Protection Requirements

GB8702-88, "Electromagnetic Radiation Protection Regulations" of the People's

Republic of China specifies:

1. Public radiation: For twenty-four hours in a day, the average power density of

electromagnetic radiation (for six consecutive minutes) is < 0.4W/m

3000MHz).

2. Professional radiation: For eight work hours in a day, the average power density

of electromagnetic radiation (for six consecutive minutes) is < 2W/m

~ 3000MHz).

2.1.5 Grounding Inspection

The grounding regulations and resistance requirements (including the lightning

protection requirements) are as follows:

The communication equipment should be well grounded for reliable operation. Good

grounding ensures lightning protection and interference resistance. The grounding

2-4

(30MHz ~

(30MHz

Chapter

cables in the equipment room should be routed in a radiating or flat way. Three

independent grounding cables should be used. The protection ground of the DC power

distribution system, the work ground of the power system and the lightning protection

ground.

The grounding resistance of the BTS should be less than 5Ω. The engineering requires

the grounding resistance to be the smallest possible. The magnitude of grounding

resistance is affected by grounding post resistance, leading wire resistance, contact

resistance between the grounding post and soil, and soil type of. The greatest impact on

grounding resistance comes from soil type. In areas with poor soil conditions, some

resistance-reducing agent (such as propenamide) may be added around the grounding

stake to meet the requirements. Changes in temperature will also cause variations in

resistance. In cold areas, the impact of temperature on the resistance may be reduced

by burying the stake deeply into the ground. Grounding stakes are usually made of

galvanized materials, in proper size. The connection cables from the grounding stake to

the equipment should adopt copper-sheathed wires of good conductivity (core wire

section area less than 50mm

, and length as short as possible). If necessary, anti-erosion

protection can be provided to the grounding connection parts to guarantee

low-resistance connection.

Error! Style not defined. Error! Style not defined.

The working ground refers to the loop formed through the earth to transmit energy and

information. For instance, the 3-phase AC power supply neutral line ground and the

positive battery ground are both working grounds. This grounding approach can resist

electromagnetic interference and crosstalk.

The protection ground refers to the grounding of the metal shell of the power supply

equipment to prevent hazards to human body due to power leakage.

In addition, the ground for lightning protection should be used to prevent lightning

strike from damaging the equipment and to protect the safety of lives and properties.

Drill holes by taking the following steps:

1. Before drilling, use a sample drill bit to drill a hole at the hole position to help

position the right drill bit. If you use the M12 expansion bolt, you should use the

Φ14 percussion drill bit.

2. The hole depth is the tube length of the expansion bolt plus the length of the bit.

After the hole depth is determined, fix the locating rod of the percussion drill;

3. When drilling, it is recommended that one person drill the holes and the other

clean dust with a cleaner;

4. Put an expansion bolt in the drilled hole and hammer it in with a rubber hammer.

Fix the bolt with its nut and then remove the nut to get ready for the rack

installation. Make sure that the expansion bolt must be securely fixed. If not, the

rack cannot be securely installed.

The rack installation check covers the following aspects:

1. Levelness: Since the floor may be uneven, it is necessary to check the levelness

of the rack after installation. Put the level bar on the level section of the rack

front and side to see if the level vial is centered. If not, it shows the rack is not

installed horizontally. In that case, adjust the legs between the rack and the base

at the four corners of the rack bottom. In the case the floor is uneven and there is

big error, use gaskets to adjust the rack levelness;

2. Verticality: Check the rack verticality with a plumb. The verticality error

between the rack bottom and the rack top should be less than 3mm;

3. Stability: The rack should stand still when you push the upper part of the rack

with your hands;

4. Check the corners in the rack. There should be no metallic scraps or wires left

during the installation, and the rack interior should be clean without any

sundries;

5. All screws are tightened with flat washer and spring washers installed in the

correct sequence.

4.5 Cabinet Installation Requirements

The installation of the ZXC10-BTSB I2 rack should satisfy the requirements for

equipment heat dissipation and maintenance space. Therefore, the rack installation

position design should meet the rack layout requirements. The cabinet installation

criteria are as follows:

1. The layout of the cabinets should take into consideration the direction from the

feeder to the BTS. The feeder should meet the bending radian requirement and

be as short as possible.

2. There must be an aisle no less than 1m wide in the cabinet front.

3. There must be maintenance room no less than 0.8m in the cabinet rear.

4. A rack space should be reserved at one side of the cabinet for future system

expansion, and the other side is away from the wall at least 0.1m.

5. When the system is expanded to three carriers and four carriers, two cabinets are

required. If they are placed side by side, it is necessary to remove the cable hole

cover plates on the side panel of the cabinets that contact each other to ease the

backplane is to be replaced, the power cables need to be connected on site.

1. Connection between the DC distribution cabinet and the DC distribution panel

The PE grounding bar of the DC distribution cabinet must be reliably connected

to the protective grounding bar provided by the carrier through the yellow/green

wire with the copper core, plastic insulation layer and the same diameter as the

power cable.

The two -48V terminal blocks of the DC distribution cabinet should be reliably

connected to the -48V DC negative busbars of the active/standby DC

distribution panels respectively. The GND terminal blocks of the DC distribution

cabinet should be reliably connected to the -48V DC positive busbars of the

active/standby DC distribution panels respectively.

If there is no DC distribution cabinet, PE wiring terminals of the cabinets must

be reliably connected with the protective terminal blocks provided by the carrier.

The power cables led out from -48 V and GND wiring terminals of each cabinet

are directly connected to the -48V DC negative busbar and -48V DC positive

busbar of the DC distribution panel.

2. Connection between the DC distribution cabinet and the cabinet

Connect one end of the -48V power cable (blue, 16 mm2) to the -48V wiring

terminal on the filter of the cabinet, and the other end to the -48V busbar of the

DC distribution cabinet.

connected to the PE wiring terminal on the P power supply of the cabinet, and

the other end to the PE busbar of the DC distribution cabinet.

3. Intra-module cabinet cascading

In the same module, the GND wiring terminals of each cabinet should be

connected with each other via a shorted cable.

4. Precautions for connecting power cables

While fixing the lug at one end of the DC distribution frame, add the flat washer

and spring washer to make sure that the lug is reliably fixed and that the cable

and wiring bar are in good contact to minimize the contact resistance. For details,

6 Installing the Grounding System

Summary



This part describes:

● Installation method of the BTS grounding system;

● Installation procedure of the BTS grounding system.

6.1 Overview of the BTS Grounding System

The purpose of grounding is to ensure the safety of human body and equipment and to

improve the capability of the equipment to resist electromagnetic interference.

The grounding system consists of indoor part, outdoor part and underground ground

grid of the building.

As to the engineering, the user is responsible for the basic ground grid construction of

the grounding system, the grounding engineering of the iron tower and the building,

and the provision of the connecting point for the indoor and the outdoor grounding

copper bars to connect the ground grid via separate 50mm

6.1-1.

The wire of the indoor rack PGND (protection ground) is connected to the indoor

grounding copper bar, as shown in Fig. 6.1-1.

The wire of the BTS rack –48VGND (working ground) is connected to the working

ground terminal of the BTS DC power rack.

To ground the lightning arrester, connect it to the outdoor grounding copper bar with a

wire. And to ground the feeder, connect each feeder to the outdoor grounding copper

bar through a grounding clip before it enters the equipment room, as shown in Fig.

6.1-1.

This section describes the grounding of the BTS equipment and the installation of the

grounding device accessories required for the BTS installation. It covers the

wires, as shown in Fig.

under the feeder window or on the rainproof wall of the feeder well on the roof top. In

principle, it is better to put it close to the feeder window.

During the practical installation, first determine the installation position of the

grounding copper bar by following the engineering design drawing, and then install the

grounding copper bar on the wall with the expansion bolts. See Fig. 6.2-1 for the

structure of the grounding copper bar.

6.2.2 Installing the Feeder Grounding Clip

Caution:

No installation of grounding clip should be performed in case of any lightning strike,

lest bodily injury may be incurred.

When installing the grounding clip, keep the feeder at the joint of the grounding clip

and the feeder straight.

6.2.2.1 Grounding Principles of Main Feeders

1. Usually, each main feeder should be grounded with grounding clips at least at

three positions: on the tower platform, at the place where the main feeder leaves

the tower for the outdoor cabling rack, and before the cable enters the equipment

room. When the main feeder is over 60m, grounding clips should be added in

the middle of it. Generally, a grounding clip is installed on the feeder every 20m.

6-3

ZXC10-BTS (V5.4) Installation Manual

2. The antenna feeder system, antenna support and new cabling rack installed on

the roof top should be welded to the lightning protection grid of the building.

The feeder should also be grounded at three positions: where it leaves the

antenna embracing pole, where it leaves the roof top, and where it enters the

equipment room.

3. When the main feeder enters the equipment room from the roof top along the

wall, the outdoor cabling ladder provided by the network operator must be

grounded. If not, urge the network operator to finish it as soon as possible.

Installing the Grounding Clip

6.2.2.2

1. Prepare the tools: Paper cutter, flathead screwdrivers, wrench and sharp-nose

pliers.

2. Select a proper installation position for the grounding clip. And cut open the

sheath of the 7/8" feeder to the size of the grounding clip. The structure of the

grounding clip is as shown in Fig. 6.2-2

grid. No reverse direction is allowed. The angle formed by the grounding wire

and the main feeder should not be more than 15°C. No reverse folding is

allowed.

In the case the antenna feeder system is installed on the tower, the grounding

wire of the grounding clip should be led downward along the tower body.

6-4

Chapter

In the case the antenna feeder system is installed on the roof top, the grounding

wire of the grounding clip should be led close to the building lightning

protection grid.

4. Before installing the grounding clip, wrap the grounding wire at the grounding

clip end that is close to the grounding wire copper sheet with the waterproof

adhesive tape, as shown in Fig. 6.2-3. This can improve the sealing effect and

prevent the rain from falling into the feeder interior along the grounding wire.

Fig. 6.2-3 Wrapping the Grounding Wire of the Grounding Clip with Waterproof Tape

Error! Style not defined. Error!

Style not defined.

5. Clamp the feeder external conductor with the grounding wire copper sheet and

the locking spring plate, so that the grounding wire copper sheet and the feeder

external conductor are fully meshed.

6. Take the following steps to conduct the waterproof treatment to the joint of the

grounding clip and the feeder:

1) First wrap the waterproof adhesive tapes and then wrap the PVC tapes.

2) To wrap the waterproof adhesive tapes, apply them layer by layer from bottom

to top first, then from top to bottom once again, and finally from bottom to top

thrice, that is, wrap three layers of them. During the process, make sure the

upper layer overlaps the lower layer by about half the width of the tapes.

7. The grounding end of the grounding clip can be connected to the main tower

body or the outdoor cabling rack (connected to the lightning protection grid of

the building) on the roof top. Remove paint and oxide within the radius of about

13mm at the connection place, and cover the clean area with antioxidant to

ensure good electric contact. When the grounding end is connected, paint

another coat of antirust paint.

8. Before the main feeder enters the room, the grounding end of the grounding clip

can be connected to the outdoor grounding bar.

6-5

ZXC10-BTS (V5.4) Installation Manual

6.2.3 Installing the Indoor Lightning Arrester

For the wide-band lightning arrester that need not be grounded separately, you may

directly connect it in serial to the place between the main feeder and the indoor set top

jumper. During the installation, the lightning arrester and indoor equipment as the

cabling rack should be insulated.

For the lightning arrester that need be grounded, a lightning arrester frame should be

provided. Please refer to the assembly instructions provided by the supplier for the

assembling of the lightning arrester frame. The installation steps are as follows:

1. Install the lightning arrester on its frame in advance.

During the installation, please note that the connectors at both ends of the

lightning arrester are different: One end is a DIN male connector (DIN-M) and

the other is a DIN female connector (DIN-F). Make sure that the DIN-M

connector of all the lightning arresters installed on the frame are in the same

direction, and the DIN-F connector of all the lightning arresters are in the same

direction. The lightning arrester should be securely installed on the frame and in

close contact with the frame.

2. Fix the assembled lightning arrester to the cabling rack.

Plan the installation position carefully to make both the main feeder and the set

top jumper easily be connected to the lightning arrester and to enable easy

cabling.

The lower part of the lightning arrester frame that is secured to the cabling rack

can be adjusted according to the width of the cabling rack.

When the lightning arrester frame is installed on the cabling rack, make sure that

its DIN-M connector points to the main feeder and its DIN-F connector points to

the connection line from the jumper to the rack.

3. The lightning arrester is installed indoor. Its grounding wire should be connected

to the outdoor grounding copper bar and should not contact with the conductor

of the indoor cabling rack. The lightning arrester frame is insulated from the

cabling rack.

The installation of the lightning arrester frame is as shown in Fig. 6.2-4.

7 Installing the Cabinet Internal Cables



Summary

This part describes:

● Configuration types of BTS and precautions of the

installation of the front panel RF cables;

● Cable installation in BTS single-carrier and two-carrier

configurations;

● Cable installation in BTS three-carrier above

configurations.

7.1 Overview of the Internal Cable Installation

7.1.1 Configuration Types of BTS

A macro BTS can be configured in various ways, e.g., single-carrier three-sector,

two-carrier three-sector and four-carrier three-sector as required by the installation

environment and traffic conditions.

The RFE model varies with the BTS configuration and the number/length of

connection lines configured for the front panel of the rack. The following sections

describe the typical configurations: Single-carrier single-sector, single-carrier

two-sector, single-carrier three-sector, and two-carrier three-sector.

7.1.2 Precautions for Installing the RF Cables on the Front Panel

The front panel of the BTS rack uses RF cables to transmit the uplink and downlink RF

signals between RFE, HPA and TRX. N-type interfaces and SMA interfaces are use.

During the cable installation, make sure to align the cables to the interfaces and screw

them tight.

Generally, the RF cables have been deployed for a new base station and what needs to

do is only take the feeder connectors out of the cabling trough on the front panel and

7-1

ZXC10-BTS (V5.4) Installation Manual

connect them to the RF interfaces on the front panel. However, re-cabling is required

for a base station to be expanded in capacity. Note that the RF cables are attached with

labels at both ends. The details are as follows:

1. The upper end (DIN connector) of the 1/2'' feeder from the RF front end to the

rack top has been installed to the rack top before factory delivery, so the onsite

installation only involves its lower end. During the installation, remove

dustproof cap from the lower end (N-type connector) of the feeder, hold the

lower end and slightly push the middle part of the feeder so that the feeder bends

naturally and its lower port aligns to the ANT port on the front panel of RFE,

and then fasten the screw cap. Please be noted that during the installation you

should align both the port and the screw cap to smoothly screw tight the 1/2''

feeder because it is short and has a certain rigidity.

2. Fig. 7.1-1 shows the structure of the RF connection lines between RFE, HPA

and TRX. The cables have all been deployed for the rack before factory delivery

if the base station is newly built. During the installation, open the baffle of the

cabling slot on the front panel and take out the connectors (SMA) and connect

them to the corresponding positions against the labels on the cables. For the

specific content of these labels, please refer to the information about "End A

Direction" and "End B Direction" given in Table 7.2-1, Table 7.2-2, Table 7.2-3

and Table 7.2-4 concerning the "Front Panel Wiring List" of multiple

configurations. Please also be noted that you should check the connectors

against the cable labels once again after installing them.

Label

Fig. 7.1-1 Structure of the RF Cables on the Front Panel of the Rack

3. Some additional RFE, HPA and TRX modules are needed for a base station

requiring capacity expansion. The RF cables connecting them need onsite

connection. To do so, you should select the RF connection cables according to

the configuration requirements of the base station to be expanded, deploy the

feeders tidily and bind them securely inside the cabling troughs in accordance

7-2

Chapter

Error! Style not defined. Error! Style

not defined.

with the route requirements as regulated in the cabling diagram, and then

connect them one by one as instructed by their labels.

4. A load of 50Ω should be matched to each port that does not connect any RF

cable.

5. The cabling should be neat and in order, and no cable should be damaged during

the bundling or cutting of their cable ties.

7.2.5 Connecting the Backplane Signal Cables for the Rack of a Single-carrier or Two-carrier BTS

The internal signal cables at the BTS rack’s backplane are: transit cable from rack top

to GPS antenna of GCM board, T1 transit cable from rack top to DSM board, LVDS

cable, HPA unit cable and BTM cable.

The ZXC10-BTSB I2 backplane cables are ready connected and tested before rack

delivery and it’s unnecessary to lay them over again during installation. For easier

expansion, the backplane cables are already laid out for the configuration of two

carriers and three sectors. For just in case, check if the cables are fast connected before

the rack is powered on. If there is a need to shoot a trouble while commissioning for

expansion purpose, the backplane indications and signal cable labels may be checked

for any connection error or cable problem.

7.3 Installing the Cables for the BTS of Three Carriers and Above

Two BTS cabinets should be combined for the BTSB I2 configuration of three carriers

and above: One basic cabinet (1#) that accommodates the GCM, DCM and SNM

modules, and one extended cabinet (2#).For easier expansion, all backplane cables for

the BTS of three carriers and above are deployed as required by the four-carrier

three-sector configuration, while the front panel cabling can be either for three-carrier

three-sector configuration or four-carrier three-sector configuration.

7.3.4 Connecting the Backplane Signal Cables of the BTS Rack

For three-carrier BTS and four-carrier BTS, the extended rack does not contain the

GCM and the DSM. Therefore, the signal transmission is made from the basic rack to

the extended rack through the rack top jumpers.

1. Connecting the backplane clock cables of the basic rack

7.4 T1 Cabke

7.4.1 Functions

Abis interface adopts T1 cable as the 100Ω coaxial cable and connects the T1 interface

of board DSM to set top. The characteristic resistance of T1 cable is consistent with the

input and output resistance of the line transceiver set by the transceiver of board T1.

7.4.2 Connection Position of Two Ends, Wiring and Signal Flow Direction of Cable

One end of the T1 cable is connected with the D-shape 44-core connector on the

backplane of BDS frame, while the other end is fixed on the transfer installation hole

of set top.

When DSM is configured as 100ΩT1, a D-shape 44-core connector is adopted on the

backplane of BDS frame. 8-channel T1 is supported; meanwhile extended 8-channel

T1 is provided. The system supports maximum 16-channel T1.

7.4.3 Function

The T1 cable used at the Abis interface is the 100Ω coaxial cable twisted pair. It

connects the board interfaces to the rack top. The characteristic impedance of the T1

cable is the same as the input/output impedance of the line transceiver set for the

board’s T1 transceiver.

7.4.4 Connection Positions of Both Ends, Cabling and Signal Flow Direction of Cables

One end of the T1 cable connects to the connector on the backplane of the IP_BDS

shelf, and the other connects to the conversion card at the rack top.

If the 100Ω T1 is used, then the DB44 high-density connector should be employed on

the backplane of the IP_BDS shelf, while the CC4 standard T1 coaxial socket should

be employed to connect the conversion card, as shown in Fig. 7.4-1 and Table 7.4-1.

On the BTS rack top, there are totally 16 T1 interfaces marked as “BSC_IP_T1-0-7”

and “EXT_IP_T1-0-7” (100Ω cable terminals are shown in ). 8 out of the 16 are active

for connecting with the BSC. The rest T1 interfaces are standby or will be used for the

daisy chain configuration of a BTS.
