Chapter Error! Style not defined. Error! Style not defined. 2-5 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 50mm2, and length as short as possible). If necessary, anti-erosion protection can be provided to the grounding connection parts to guarantee low-resistance connection. 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. 2.1.6 Inspection of the Installation Environment for the Outdoor Antenna Feeder System 1.

Only when the equipment capacity is to be expanded or 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.

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 50mm2 wires, as shown in Fig. 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

It is usually installed on the wall outside the feeder window. The best place for it is right
Chapter Error! Style not defined. Error! Style not defined. 6-3 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. Fig. 6.2-1 Profile 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.
ZXC10-BTS (V5.4) Installation Manual 6-4 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. 6.2.2.2 Installing the Grounding Clip 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 Grounding end Grounding cableFeederLocking spring plateof the grounding cableExternal coppercore of the feederCopper sheet ofthe grounding cable Fig. 6.2-2 Structure of the Grounding Clip 3. Lead the grounding wire of the feeder lightning grounding clip to the ground 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.
Chapter Error! Style not defined. Error! Style not defined. 6-5 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 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.
ZXC10-BTS (V5.4) Installation Manual 6-6 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.

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
ZXC10-BTS (V5.4) Installation Manual 7-2 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 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
Chapter Error! Style not defined. Error! Style not defined. 7-3 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 Installing the Cables for the Single-carrier BTS and the Two-Carrier BTS 7.2.1 Installing the RF Cables for a Single-carrier Single-sector BTS 1.

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

Normally it is not configured. 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.

The installation of the antenna feeder equipment is important to the installation of the BTS equipment. Its construction quality directly affects the operating performance of the entire BTS system. Most of the BTS installation engineering is the installation of the antenna feeder equipment that generally takes up 80% of the installation time of the whole BTS system. The installation of the antenna feeder equipment involves the installation of the antenna, the jumper, the routing of the main feeder, and the installation of the lightning protection system and the GPS system. Different antenna may be used due to different terrain, population density and installation environment.
ZXC10-BTS (V5.4) Installation Manual 10-2 The installation method and procedure differs. In the precondition of quality, the Installation Supervisor should install the antenna as per the actual situation flexibly and reasonably by following the BTS engineering design documents and the installation instructions of the special antenna provided by the manufacturer. Prior to the installation of the antenna feeder system, inspect the qualification of the installation staff to work at heights, check and prepare the installation environment, the installation measures, the installation tools and the antenna feeder to be installed so that the installation can be carried out successfully. 10.1.1 Preparations for Installation Staff Generally, the installation of antenna feeder system is supervised by the Installation Supervisor and carried out by the installation staff. Requirements for the Installation Supervisor: He should be familiar with the materials, tools and operation methods used in the antenna feeder installation, and be responsible for organizing the installation staff and assigning proper tasks (especially working on the tower) to the staff in the principle of "Safety First". The Installation Supervisor should fill in the engineering data faithfully. Requirements for the installation staff: Staff that can conduct the installation professionally under the instruction of the supervisor. The staff working at heights should have no acrophobia and be in good health. In addition, he should have the qualification and certificate for working at heights, observe the requirements for using the safety tools, have purchased life insurance policy, and should not drink. 10.1.2 Installation Environment Inspection The environment inspection focuses on the following: The outdoor lightning protection grounding cable should be in place with the core diameter more than 50mm2. The distance between the antenna lightning arrester, the lightning protection grounding point, the outdoor cabling rack, and the antenna embracing pole should meet the design requirement. The strength and the wind-withstanding capability of the embracing pole should also meet the design requirements. Check the preparation of the compulsory tools and engineering auxiliary materials. Both parties should negotiate and define the specific routing of the main feeder.
Chapter Error! Style not defined. Error! Style not defined. 10-3 As to the installation of the antenna support, the equipment supplier puts forward requirements for the antenna structure and dimensions, while the network operator completes the installation as parts of the equipment room accordingly. The network operator is also responsible for the installation of the antenna feeder installation environment such as the outdoor cabling rack, the lightning arrester, the lightning protection grounding peg, and the outdoor lightning protection grounding cable. The construction of the wall or the hole on the roof for the feeder window where the main feeder enters the room involves the infrastructure of the equipment room. It should be completed as part of the equipment room by the network operator. 10.1.3 Safety Measures Inspection Caution: The staff working on the tower must wear the safety belt and must not wear loose clothes or slippery shoes, while the staff under the tower must wear the safety helmet. 1. Emphasize the safety precautions to the engineering staff. 2. The outdoor engineering of the antenna feeder should be conducted on a fine day without strong wind. 3. Distinct marks should be set up at the engineering site to keep off people irrelevant. The staff working under the tower have the obligation to clear the people irrelevant on-site, especially children, off the site. All the tools and instruments that might fall off the tower and hurt the personnel under the tower must be strictly handled. For example, the tools and metal installation parts that are temporarily not used on the tower should be put in a canvas tool bag. The bag should be closed once you take out the tool you need. 10.1.4 Preparation of Installation Tools Installation tools comprise the following: 1. Measurement tools: Compass, multimeter, angle meter, tape; 2. Communication tools: Two MSs; 3. Hoisting tools: Pulley, rope to pull the main feeder;
ZXC10-BTS (V5.4) Installation Manual 10-4 4. Special tools: Main feeder cutter, special tools for preparing main feeder connectors; 5. General-purpose tools: Adjustable wrench, sharp-nose pliers, diagonal pliers, electrical knife, file, hacksaw; 6. Safety protection tools: Safety belt (used by engineering staff who step out of the platform on the tower), safety helmet, safety rope, thick uniform, RF-proof clothing, canvas tool bag, gloves, multi-purpose power socket; 7. Others: Standing ladder, wooden axle hoisting tool for the main feeder (this can be borrowed from the local user). 10.2 Structure of the Antenna Feeder System As shown in Fig. 10.2-1, the antenna feeder system comprises antenna, antenna jumper, main feeder, lightning arrester, set top jumper, grounding parts and others.

ZXC10-BTS (V5.4) Installation Manual 10-6 Caution: 1. Take careful precautions for the safety of yourself and the equipment during the whole antenna installation process; 2. When adjusting the antenna that is already working, take certain measures (for example, wear radiation-shielding clothing), and turn off the high power amplifier to avoid the direct radiation of the antenna to human body. 10.3.1 Technical Parameters for Antenna Installation 1. Antenna height It is determined by network planning. 2. Azimuth of antenna It is determined by network planning. 3. Pitch angle of antenna It is determined by network planning. Usually 0° ~ 10° adjustable. 4. Antenna direction It is determined by the azimuth of the antenna. Two antennas in the same sector should point to the same direction. 5. Distance between diversity antennas The two antennas in the same sector are diversity receiving antenna to each other with the same vertical height. The horizontal distance (d) is as large as possible to satisfy the engineering requirements just by following the formula below. d ≥ 10~20λ (or H/d = 11), where d is the horizontal distance between the diversity antennas, and H is the vertical height from the antenna to the floor. The diversity distance of the 1900M carrier should be more than 1.5m while that of the 800M carrier should be more than 3.5m. 10.3.2 Antenna Installation Flow The antenna installation flow is shown in Fig. 10.3-1.

And design modification solution should be made then after consultation with the user representative and the design institution, lest the network coverage after the installation be affected. 10.4.2 Handling and Hoisting the Antenna Caution: Personnel both on and under the tower should coordinate to hoist the antenna. During the hoisting process, the personnel under the tower should pull the antenna away from the tower body by pulling the rope, lest the antenna be damaged due to crash with the tower body. In the case the antenna is to be installed on the tower, use the rope and pulley block to hoist the antenna, the 3m antenna jumper and all the accessories (such as tools, safety belts, adhesive tapes and straps) to the tower-top platform and place them in a safe place. Take corresponding safety measures during the process. Small metal staff as antenna fixing parts and wrenches should be put in a sealed canvas tool bag before hoisting, as shown in Fig. 10.4-1. Both ends of the directional antenna and the omni-antenna should be knotted for easy coordination of the staff both on and under the tower during the hoisting. In the case the antenna is to be installed on the roof, move the antenna and the installation materials to the installation position manually.

This section takes the Kathrein antenna as an example to describe the antenna installation process. Please carefully read the installation instructions provided along with the antenna during the installation and install the antenna as per the actual situation. 1. Initial assembly of the directional antenna fittings The directional antenna has a number of installation fasteners. For example, the Kathrein antenna has two types of fasteners: 738516 and 737974. Before fixing the antenna, assemble fastener 737974 to the ends of the antenna, as shown in Fig. 10.4-2, and then connect fasteners 737974 and 738516. Thus the initial installation of the directional antenna is complete. All accessories must be installed with spring and flat washers. Please refer to the instructions attached to
ZXC10-BTS (V5.4) Installation Manual 10-10 the product for descriptions of other fasteners for the antenna of other manufacturers or of Kathrein. Usually the antenna fixing accessories and the angle adjustment device accessories have been installed on the antenna under the tower. 2. Initial fixing of the directional antenna on the antenna embracing pole Mount the directional antenna installed with clamp accessories on the antenna embracing pole: The screw should not be too tight that you are unable to adjust the direction and the pitch angle of the antenna, nor too loose lest the antenna slip downward. 3. Adjusting the azimuth of the antenna 1) Determine the azimuth of the antenna using a compass. And determine the installation direction of the directional antenna according to the engineering design drawing; 2) Turn the antenna slightly to adjust its face direction, as shown in Fig. 10.4-2. At the same time measure the direction of the antenna with a compass till the error is within the engineering design requirements (generally not more than 5°); 3) After adjusting the azimuth of the antenna, tighten the fastener 738516.

ZXC10-BTS (V5.4) Installation Manual 10-12 Fig. 10.4-3 Adjusting the Pitch Angle of the Antenna 10.4.4 Installing and Adjusting the Omni Antenna Take the following steps to install the omni antenna: 1. Put the jacket at the antenna lower part close to the support backbone. The top of the jacket should be flush with or slightly higher than the support top; 2. Fix the jacket at the antenna lower part and the support backbone at two points with antenna fixing clips. They should be fixed tight enough to bear weight and withstand wind, and should not be too loose or too tight lest the antenna jacket be damaged. 3. Check the antenna verticality. The omni antenna must be vertical. Make sure the antenna is vertical, and then fix it to the antenna embracing pole. 4. Stick the support installed with the antenna out of the tower platform, and adjust the support to make the antenna vertical. 10.4.5 Connecting and Sealing the Jumper and the Antenna  Note: The antenna and the jumper can be connected and waterproof treatment can be conducted on the joint before the antenna is fixed on the embracing pole. This can reduce the time working at heights and improve the joint connection and waterproof quality. The installation steps are as follows: 1. Align the connector of the antenna jumper to the antenna interface and screw it tightly.
Chapter Error! Style not defined. Error! Style not defined. 10-13 2. Perform waterproof treatment to the joint (See section 10.6 "Waterproof Treatment on Joint" for details): 1) Wrap starting from the root of the antenna joint with waterproof adhesive tape in the same direction as the fastening direction of the antenna jumper; 2) Stretch the waterproof adhesive tape to double its length, and apply it layer by layer till it covers about 5cm of the bottom of the feeder joint. During the process, make sure the upper layer overlaps the lower layer by half the width of the tape. 3) Grip the tape with hands to make the tape tightly adhered; 4) Apply the PVC tape layer by layer on top of the waterproof adhesive tape. During the process, make sure the upper layer overlaps the lower layer by half the width of the tape. 10.4.6 Installing the Feeder Window  Note: The feeder window provided by ZTE is a four-hole one with the dimensions of 400mm × 400mm. Altogether 12 feeders can go through the feeder window, and the dimensions of the cavity on the wall can be 300mm × 300mm. If the user provides a special feeder window, then make the wall cavity according to the actual dimensions of the feeder window. The feeder window is usually mounted on the wall outside the equipment room between the indoor and the outdoor cabling racks. If the main feeder window is to be installed on the building-top, sealing and waterproof treatment should be conducted on it. You may use asphalt or glass cement to seal the feeder window. The feeder window has four or nine holes and the 4-hole feeder window is as shown in Fig. 10.4-4. Table 10.4-1 shows the specifications of varying feeder windows. Follow the steps below to install the feeder window: 1. Determine the installation position of the feeder window as required by the engineering design drawing; 2. Make a cavity on the wall according to the size of the feeder window;
ZXC10-BTS (V5.4) Installation Manual 10-14 3. Drill holes for the expansion bolts using a percussion drill and fix the main board of the feeder window with expansion bolts; 4. The sealing gasket and sealing tube of the feeder window can be installed when the main feeder is introduced into the room. See section 10.4.7.6 "Introducing the Main Feeder into the Equipment Room"; 5. For cold areas with sand storms, even if the wall is thick, it is necessary to install timber baffle plates inside the equipment room to keep warm and keep sands outside.

If the layout of the feeder need be modified as per the practical situation, you should consult the user representative and try to solve the problem as early as possible. Please note that the length of the main feeder should be as short as possible.
ZXC10-BTS (V5.4) Installation Manual 10-16 10.4.7.2 Preparing the Main Feeder Connectors Caution: The preparation of the feeder connector is the most important part in the antenna feeder installation engineering. The quality of the job directly affects the equipment operation and the network quality. Since the cutting tool used is sharp, use it correctly to avoid body injury. This section takes the Rosenberger 7/8" feeder connector as an example to describe the preparation process. For the installation of the feeder connector of other specifications or other manufacturers, please refer to their installation instructions. Take the 7/8" main feeder connector as an example. The procedure to make the connector is as follows: 1. The common cutting tool to make the feeder connector is as shown in Fig. 10.4-6. Fig. 10.4-6 Cutting Tool for the 7/8" Feeder Connector 2. Measure a straight feeder section of about 150mm to be installed with the connector, and cut and strip the feeder sheath 50mm away from the end using a safety cutting tool. 3. Put the feeder into the notch of the cutter (EASIAX), leaving a length of four sheath threads from the main blade. And then close the cutter handles. Since the position of the cutter is determined according to the threads on the external copper sheath of the feeder, the main blade should just be aligned to the crest at the center of a thread of the feeder.
Chapter Error! Style not defined. Error! Style not defined. 10-17 4. Turn the cutter in the direction as marked on the cutter till the handles are completely closed and cut the internal and external copper conductors of the feeder completely. At the same time, the auxiliary blade of the cutter cuts the external plastic protection sheath of the feeder, as shown in Fig. 10.4-7. Fig. 10.4-7 Cutting the Feeder with a Cutter 5. Check the cutting length of the feeder, as shown in Fig. 10.4-8. Crest position Fig. 10.4-8 Checking the Cutting Length of the Feeder 6. Separate the front part and back part of the feeder connector, and insert the back part into the feeder till it contacts with the first corrugation of the feeder. 7. Firmly insert the tube expander of the cutter into the feeder and turn it left and right to expand the external copper conductor of the feeder, so that it presses against the back part of the feeder connector, as shown in Fig. 10.4-9. Fig. 10.4-9 Expand the External Conductor of the Feeder with a Tube Expander
ZXC10-BTS (V5.4) Installation Manual 10-18 8. Check whether there is residual copper scraps. The external copper sheath should be evenly expanded without burrs. Pull the back part of the feeder connector outward while keeping it from slipping away from the feeder. If it does separate from the feeder, make it again. 9. Connect the front part and the back part of the feeder connector, as shown in Fig. 10.4-10. Fig. 10.4-10 Connecting the Front Part and the Back Part of the Feeder Connector 10. Screw the front part of the feeder connector, and fix it with an appropriate wrench, so that it does not move against the feeder. Then screw the back part of the feeder connector with the wrench till it is fixed, as shown in Fig. 10.4-11.

Chapter Error! Style not defined. Error! Style not defined. 10-19 10.4.7.3 Cutting the Feeders Caution: When cutting the main feeder, label it at both ends. Temporary label can also be attached to the middle of the feeder. All the labels must be consistent. Otherwise, the feeder may not be correctly connected and the sectors may not correspond to the feeder. This is crucial! Usually the feeder is rolled over to the installation site. The length of the main feeder should be exactly measured again on site according to the final route negotiated with the user. And the feeder should be cut into sections as required. The cutting steps are as follows: 1. For the antenna feeder to be installed on the roof 1) Determine the length of the main feeder in each sector again with a tape measure according to the actual route; 2) Cut the feeder to the length of the measured actual length plus 1m to 2m; 3) After cutting a main feeder, attach the corresponding temporary label to both ends of the feeder, for example, ANT1, ANT2, ANT3, ANT4, ANT5 and ANT6. When the feeder is installed, attach the formal label to it. 4) Move the cut feeders to the roof. During the process, take care that the feeders are not damaged or pressed. 2. For the antenna feeder to be installed on the tower 1) Use roller support, pulley block and hoisting rope to lift one end of the feeder to the tower top. The personnel under the tower cut the feeder to the length from the feeder enters the equipment room to the lightning arrester frame plus certain redundancy. Attach temporary labels to the lower part of the feeder. When the feeder enters the equipment room, attach the formal label to it. 2) It is better to make the upper connector of the main feeder before hoisting it to reduce the time that the staff works at heights and to better ensure the installation quality of the feeder connector.
ZXC10-BTS (V5.4) Installation Manual 10-20 10.4.7.4 Hoisting the Main Feeders of the Iron Tower Caution: During the hoisting, rough operations are not allowed, lest the sheath of the main feeder be damaged or scratched. The partial damage of a single main feeder will cause the whole cable be rejected as useless. Take precautions for personal safety when hoisting the feeders. If the main feeder is to be installed on the tower, pulley blocks should be used to hoist the main feeder, as shown in Fig. 10.4-12. Take the following steps to install the main feeder: 1. Check again that the main feeder labels attached 0.3m away from both ends of the main feeder are correct; 2. Wrap the main feeder connector made under the tower with flax (or antistatic packing bag together with foam) and strap it tightly. 3. Knot and fix the hoisting rope 0.4m and 3.4m away from the feeder connector to help the staff both on and under the tower pull up the feeder and to prevent the feeder and its connector from damage caused by their bumping into the tower during the hoisting process. 4. After the feeder is hoisted to the tower platform, fix the upper end of the cable to a proper place at several points, lest the cable fall down from the tower.

Cabling principle of the main feeder ● The main feeder that enters the equipment room from the feeder window and is routed along the indoor cabling rack should be bound neatly without crossing. ● The main feeder that is routed along the indoor cabling rack and the cabling rack on the tower should have no crossing; ● Make yourself familiar with the routing of the main feeder before cabling it. It is better to take down its actual route on paper to avoid rework due to crossing the cable;
ZXC10-BTS (V5.4) Installation Manual 10-22 ● The minimum bending radius of the main feeder should not be less than 20 times the length of the radius of the main feeder. For one-time bending, the minimum bending radius is 90mm. The minimum bending radius of repeated bends is 200mm. ● The maximum spacing between the hangers is 1.65m. 2. Cabling procedure of the main feeder 1) Pre-install the three-feeder clips every 1.5 meters (or as per the actual condition of the iron tower, but no more than 1.65 meters) along the iron tower or cabling rack. Note that the spacing should be as even as possible and the direction of installing them should be the same. When installing two rows of feeder clips inside the same cabling ladder, the two rows should be parallel and arranged neatly. Fig. 10.4-13 shows the outside view of a three-feeder clip.

Installation procedure
ZXC10-BTS (V5.4) Installation Manual 10-24 1) Loosen the fixing hoop from the feeder window to the proper position with reference to Section 10.4.6, "Installing the Feeder Window", and pull away the sealing cover of the aperture to thread the feeders. 2) Lead the feeders into the equipment room: Two persons are needed to cooperate with each other, one indoors and the other outdoors, to introduce the feeders from the outdoor cabling racks into the indoor cabling racks. During this process, care should be taken to avoid damaging the indoor equipment or damaging the feeder due to improper force applied on the outdoor feeder. Fasten the fixing hoop after pulling the feeders in place. 3) Cut the feeders. Pay attention to the following: ● Check the labels: Ensure that the temporary labels on the feeders are complete before feeder cutting and are still attached on the feeders after cutting. This is very important to avoid feeder chaos. ● Determine the cutting position: When cutting the feeders, select the cutting position according to the equipment room conditions (such as the rack installation position, the set top jumper length, the lightning arrester configuration or the installation position of the lightning arrester frame), the bending radii of the feeders and the cabling requirements of the equipment room. 4) Prepare the indoor connectors for the main feeders. 5) Connect the main feeders to the lightning arresters. If a lightning arrester is not grounded, it should be directly mounted onto the feeders to ensure proper insulation between the lightning arrester and the cabling rack. If a lightning arrester is equipped with a lightning arrester frame, each feeder should be thoroughly adjusted to ensure the screw threads properly fit in with the lightning arrester when the main feed and the arrester are connected. For details, refer to Section 6.2.3, "Installing the Indoor Lightning Arrester".
Chapter Error! Style not defined. Error! Style not defined. 10-25 10.4.8 Installing the Indoor Jumpers Indoor set top jumpers are used between the lightning arrester connected to the main feeder and the rack. Usually the finished 2m set top jumpers are used, or the jumpers can be prepared on site as per the actual length required. If the 2m finished jumpers are used, they can be directly installed between the lightning arrester and the rack top. If the jumpers are prepared on site, 1/2'' feeders should be prepared through cutting according to the specific length of each jumper. Assemble proper feeder connectors onto both ends of the feeders according to the feeder connector assembly instructions, and connect the jumpers between the lightning arrester and rack top. 10.5 Checking and Testing the Antenna Feeders After installing all the antenna feeders, conduct the SWR test on each of them. The measured SWR should be less than 1.5 and usually less than 1.3. If this is not satisfied, check immediately the feeder connectors installed, antenna, feeders and lightning arresters to find where the problem comes from. For the method of SWR test with SiteMaster, refer to Appendix G. 10.6 Waterproof Treatment for the Connectors Caution: The waterproof sealing for the outdoor jumpers and the feeder grounding clips of the antenna feeder system is an important part of the antenna feeder installation. It is of special concern. In the installation process, make sure to use waterproof tapes properly to ensure the quality of installing the antenna feeder system. Use 1/2'' jumpers, generally the 3m finished jumpers, between the antenna and main feeder for transition. Connect the 1/2'' jumper and the feeder and seal their connectors as follows: 1. Connect and fasten the antenna jumper and the main feeder connector 2. Make waterproof treatment on the connectors in the following steps:
ZXC10-BTS (V5.4) Installation Manual 10-26 1) Cut waterproof adhesive tapes about 200mm long; 2) Wrap the waterproof adhesive tapes from a low position where the connector is connected and apply them about 200mm long to fill the low-lying parts of the connector, as shown in Fig. 10.6-1. Fig. 10.6-1 Wrap the Waterproof Adhesive Tapes (1) 3) Extend the adhesive tapes to double their length when wrapping them. The direction of wrapping should be the same as the direction of screwing the feeder connector, lest the feeder connector be loosened during the wrapping process. 4) As shown in Fig. 10.6-2, wrap the adhesive tapes layer by layer and then wrap them again in the reverse direction. The upper layer covers the lower layer by about 1/3 to avoid water penetration. Finally, reverse the direction and wrap them layer by layer again. Apply the tape with three layers without any cut in the entire process. Wrap the tapes around the feeder connector till they protrude about 20mm from the feeder connector. Fig. 10.6-2 Wrap the Waterproof Adhesive Tapes (2) 5) Grip the waterproof adhesive tapes after wrapping them to ensure firm bonding between the tapes and the feeders/feeder connectors, as shown in Fig. 10.6-3.
Chapter Error! Style not defined. Error! Style not defined. 10-27 Fig. 10.6-3 Wrap the Waterproof Adhesive Tapes (3) 6) Apply two layers of the PVC tape on top of the waterproof adhesive tape. During the process, make sure the upper layer overlaps the lower layer by half the width of the tape. 7) Grip the PVC tapes and the waterproof adhesive tapes to make them tightly adhered to each other. 8) Tie the two ends of the adhesive tape with straps to prevent it from being aged or falling off.

According to the passive distance measurement principles, GPS antenna receives the navigation positioning signals from the GPS satellites and demodulates frequency and clock signals through the GPS signal receiver for use by the related units of the CDMA base station. Requirements for the installation of the GPS antenna: The installation position of the GPS antenna should have a broad view so that the GPS antenna can track satellites as many as possible. Usually, select a safe place on the roof or at the lower part of the tower and try to make the GPS feeder short to reduce attenuation. Requirements for the lightning protection of the GPS antenna: Usually, the GPS antenna is installed within the 45° lightning protection coverage of the tower. If it is not within the coverage, the user is required to prepare and install the lightning arrester for it.

FAX: 0086-755-26770160 12-1 12 Installing the Boards  Summary This part describes: ● Board types of BTS; ● Installation and replacement methods of the BTS boards; ● Front panel and interface of some BTS boards; ● Installation sequence of the BTS boards. 12.1 Board Types and Functions of BTS Modules of the BTS are: 1. DSM DSM (Data Service Module) lies in the BDS of the BTS. It implements the trunking, data and signaling processing of Abis interface. It provides 16 E1 lines externally. Eight are used to connect upstream BSC while other eight to connect downstream BTS, which support the daisy chain networking mode and can also function as E1 extension to connect upstream BSC. This board may also connect to the transmission network to support SDH optical transmission connections. 2. CCM CCM (Communication Control Module) is the control core for data signaling routing, signaling processing, resources management and operation/maintenance of the whole BDS subsystem in BSS. 3. CHM CHM (Channel Processing Module) conducts modulation and demodulation of various CDMA channels and implements some power control functions.
ZXC10-BTS (V5.4) Installation Manual 12-2 4. RIM RIM (Radio Frequency Interface Module) implements the interface between BDS and RFS. The forward link first sums the baseband data sent from CHM as per different sectors, multiplexes the summation result, HDLC signaling and PP2S from GCM, and then sends them to RMM. Then the reverse link receives the reverse baseband data and HDLC signaling, selects them according to the signaling sent from CCM, then sends the selected data by broadcasting to the CHM and the HDLC data to the CCM for processing. RIM lies in the BDS frame and supports active/standby configuration. 5. SAM SAM (Site Alarm Module) monitors the running status of the PM and fans, as well as access control, flood, temperature, humidity, and smog signals. It will then report the results to the OMC console via CCM. In addition, it provides RS232 and RS485 interfaces for the connections with external monitoring devices. 6. GCM GCM (GPS Control Module) provides reliable and high-stability clock source for various modules of BTS. The major clocks include TOD (UTC timing message), system clock (16CHIP and PP2S), circuit clock (2MB and 8K) and RF reference clock (30M). 7. SNM SNM lies in the BDS and implements STM-1 downlink and uplink functions for BTS. 8. CDM CDM (Clock Distribution Module) distributes the clock of GCM in BTSB to TRX. The RF reference clock in BTSB is transmitted as the 30M MLVDS clock, while TRX needs the 10M/12M analog clock. Therefore, CDM is used to convert the 30M MLVDS clock sent from GCM to TTL signals and generate the 10M/12M analog clock needed by TRX in HIRS through the phase-lock loop. 9. RFE
Chapter Error! Style not defined. Error! Style not defined. 12-3 RFE module is the main module connecting the internal system of RFS in the BTS and the external antenna of the BTS. Its terminal port is the RF port at the top of the BTS and the test port of the BTS for system testing. It has great influence on the receiving sensitivity and exit transmitting power of the whole BTS system. 10. HPA HPA (High Power Amplifier) amplifies the power of TRX’s forward transmission signals so that the signals go through the duplex filter of RFE at a proper power value and then transmitted by antenna into the cell. The CDMA system requires that HPA should have certain linearity. 11. TRX TRX is the junction connecting RF and baseband signals. One TRX corresponds to one sector of one carrier. In the reverse channel, TRX receives the main and diversity receiving signals of the sector, conducts down conversion, median frequency filtering, AGC processing and I/Q demodulation on these signals to convert the received modulated RF signals into baseband I/Q signals. In the forward channel, TRX conducts I/Q modulation, median frequency filtering and upward conversion on the baseband I/Q signals to convert them into modulated RF signals, while also performing TPTL power control. 12. PSMD PSMB is the main power board of the whole BTS. 13. PSMC PSMC (±12V power) conducts DC/DC conversion from -48V to ±12V. The max. output of +12V is 25A and that of -12V is 8A, both providing the RFS with working power supply in the 1+1 backup mode. This module is also available with the remote control and teleaction functions. 14. PPM PPM (27V power board) conducts DC/DC conversion from -48V to +27V. It has protection functions for input over/under voltage, output over/under voltage, output over-current, and over-temperature. It employs the temperature-controlled forced cooling structure and is also available with the remote control and teleaction functions. Output current of one PPM is 25A.
ZXC10-BTS (V5.4) Installation Manual 12-4 When the load exceeds 25A, the board starts limiting current. The HPA is provided with the working power supply by several 27V PPMs connected in parallel to work in the N+1 backup mode. 12.2 Introduction to Main BTS Modules 12.2.1 RFE Module ZTE currently provides two types of RFE (RF Front End) modules. Select the module according to the BTS configuration as follows: ● RFE-DUP: Applicable to single-carrier BTS and two-carrier BTS; ● RFE-DIV: Diversity RX branch, applicable only to single-carrier BTS. The panel of the two types of RFE module is as shown in Fig. 12.2-1. All RF interfaces are located on the front panel, including the interfaces for N connection with the antenna and the connection to TRX and SMA of HPA.

The actual electrically controlled downdip of an antenna conforms to network planning and two unipolarization antennas should have consistent downdips. This is not required if it is not an electrically controlled antenna. 8. All antenna poles should be firmly installed and well grounded. All antenna poles are required to be vertical to the ground and the vertical error should be less than 2º.In particular, all antennas must be vertical to the ground. Check with a line hammer to keep the vertical error less than 2º. 9. The receive/transmit horizontal interval of an omni antenna should be no less than 3.5m. 10. An omni antenna should be at least 1.5m away from the tower while a directional antenna should be at least 1m away from the tower. 11. The jacket top of an omni antenna should be level to a support or slightly higher than the support top. 12. When an omni antenna is installed on a roof, the horizontal interval between the omni antenna and antenna lightning arrester should be no less than 2.5m. 13. An omni antenna installed on a roof should avoid blind area. 14. Check the matching relationship of the main diversity antennas within the sectors and the set top jumpers on the rack. 15. The diversity distance between two antennas within one sector refers to the vertical distance between the parallel lines of the two antennas front surfaces. It is not the distance between two antennas. Diversity distance is irrelevant to bipolarization antenna. The diversity distance should be 3.5m for 800M system, 1.5m for 1.9G system, and 6.7m for 450M system. 16. The vertical interval between directional antennas within different sectors installed on the same antenna support should be more than 0.6m. 17.
