l The RFC can only be stacked below the APM30H or TMC11H.l The IBBS200D or IBBS200T can be stacked only with the IBBS200D, IBBS200T, or

TMC11H. The IBBS200D or IBBS200T can only be stacked below the TMC11H.



19

l When a site is configured with over six RFUs and only one IBBS200D or IBBS200T, theIBBS200D or IBBS200T must be configured with at least two groups of 92 Ah storagebatteries to avoid overcurrent of a single battery group during discharging.

l If an auxiliary cabinet such as the IBBS200D/IBBS200T or TMC11H is required duringinitial site deployment, the auxiliary cabinet is positioned on the left side of the basiccabinet. If both the battery cabinet and transmission cabinet are required, the battery cabinetis positioned on the left of the basic cabinet, and the transmission cabinet is stacked on thebattery cabinet or positioned on the left of the battery cabinet.

l During base station deployment, space must be reserved for capacity expansion in thefuture. Unless otherwise stated, during capacity expansion the original cabinets remain inthe original positions and new cabinets are added to the right of original cabinets. In aspecial scenario, new cabinets can be added to the left of original cabinets.

l When a BTS3900A is configured with two BBUs and both BBUs are connected to RFUs,the BBUs must be interconnected.

l A BTS3900A configured with one APM30H and one RFC is configured with one BBU bydefault. It can be configured with a maximum of two BBUs, and the power consumptionof all BBU boards cannot exceed 1000 W. This principle applies to a new or expansionscenario.

Cabinet Configurations of a Single- or Dual-mode Base StationA single- or dual-mode base station is configured with only one BBU, and the BBU is installedin the APM30H or TMC11H. When seven to twelve RFUs need to be configured, two RFCs arerequired.

3.3 Application Scenarios of a BTS3900A Configured withRFUs and RRUs

When RFUs and RRUs are configured, different configurations of cabinets can be used for theBTS3900A in the 110 V AC/220 V AC power supply scenario and –48 V DC power supplyscenario.

Cabinet Configuration Principlesl A single BTS3900A can be configured with a maximum of six RFUs and nine RRUs.

Therefore, more than one BTS3900As must be deployed if more than six RFUs and nineRRUs are required.

l When a BTS3900A is configured with both RFUs and RRUs, a DCDU-12B is needed tobe installed in RFC, the maximum configuration of RRUs is six RRUs of 2*60 W and threeRRUs of 2*40 W.

l When both the RFU and RRU support the GSM mode, the BBU3900 must be configuredwith a GTMUb. In addition, the RFUs supporting the GSM mode are connected to theGTMUb, and the RRUs supporting the GSM mode are connected to the UBRI.

122

12.1 Cabling RequirementsRoute cables according to the specified cabling requirements to prevent signal interference.

NOTE

If a cable listed below is not required, skip the routing of the cable.

General Cabling Requirements

Bending Radius

l The bending radius of a 7/8'' feeder must be more than 250 mm (9.84 in.), and the bendingradius of a 5/4'' feeder must be more than 380 mm (14.96 in.).

l The bending radius of a 1/4'' jumper must be more than 35 mm (1.38 in.). The bendingradius of a super-flexible 1/2'' jumper must be more than 50 mm (1.97 in.), and the bendingradius of an ordinary 1/2'' jumper must be more than 127 mm (5 in.).

l The bending radius of a power cable or PGND cable must be at least three times the diameterof the cable.

l The bending radius of a fiber optic cable is at least 20 times of its core diameter. The bendingradius of a breakout cable is at least 30 mm (1.18 in.).

l The bending radius of an E1/T1 cable must be at least three times its core diameter.

l The bending radius of a signal cable must be at least five times its core diameter.

Binding

l Cables of the same type must be bound together.

l Different types of cables must be separately routed and bound, with a minimum distanceof 30 mm (1.18 in.) from each other.

l The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged.

l The cable ties must face the same direction, and those at the same horizontal line must bein a straight line.

l The extra length of the indoor cable ties is cut off. The extra length of 5 mm (0.2 in.) of theoutdoor cable ties is reserved, and the cut surfaces are smooth without sharp edges.

l After cables are installed, labels or nameplates must be attached to the cables at their ends,curves, and interconnection positions.

Security

l When routing cables, avoid sharp objects, for example sharp edges on the wall. If necessary,use tubes to protect the cables.

l When routing cables, keep the cables away from heat sources and use heat insulationmaterials to insulate the cables from the heat sources.

l Reserve a proper distance (0.1 m is recommended) between equipment and cablesespecially at the cable curves to protect the cables and equipment.

Room Entry

l Route each cable into the room through the feeder window.



123

l Reserve drip loops for all cables outside the feeder window before routing them into theroom. Ensure that the radiuses of the drip loops are more than or equal to the minimumbending radiuses of the cables.

l When routing a cable into the room, ensure that a person is assisting you in the room.l Take waterproof measures to the feeder window.

Outdoor Cabling Requirementsl Protect outdoor cables against potential damage. For example, put the cables through tubes.l The cables to be protected consist of AC power cables, transmission cables, and cables

routed underground.l When routing cables through protective tubes on the ground below the cabinet, put a 3 cm

to 5 cm (1.18 in. to 1.97 in.) length of the protective tubes into the base of the cabinet butdo not put the protective tubes into the cabinet. Use waterproof tape or waterproof silicongel to block both ends of the protective tubes and use sheet metal tabs to secure the protectivetubes to the cable holes in the base.

l When routing cables through protective tubes along a metal cable trough below the cabinet,do not put the protective tubes into the base of the cabinet but cover the cable trough andconnect the protective tubes to the cable holes in the base.

l Use clips to secure cables outdoors.l Arrange cables neatly along the routing direction and use clips to secure the cables.l Determine the positions where the clips are installed according to the actual situation. For

example, 7/8" feeders are secured with clips at an interval of 1.5 m to 2 m (4.92 ft to 6.56ft), and power cables are secured with clips at an interval of 1 m to 1.5 m (3.28 ft to 4.92ft). Ensure that the clips are evenly spaced and in the same direction.

l Clips are vertical with the cables and not bent. Cables secured with the same clips areparallel to each other.

l When using clips to secure cables, do not tighten the screws on the clips until all cables arearranged and routed.

Figure 12-1 shows the cables secured on a cable tray.



124

Figure 12-1 Cables secured on a cable tray

Figure 12-2 shows the cables secured on a tower.



125

Figure 12-2 Cables secured on a tower

Special Cabling RequirementsRouting of Power Cablesl Power cables must be installed in the position specified in engineering design documents.l If the length of power cables is insufficient, replace the cables rather than adding connectors

or soldering joints to lengthen the cables.l Cabling activities require strict organization and coordination, and are allowed only when

qualified personnel and communication facilities are available.l Circling and twisting of cables are prohibited.l After routing a DC power cable onto the platform on a tower, route it along the shortest

path to the rails surrounding the platform, and route it along the inside of the rails.l After routing a DC power cable close to the equipment on a tower, use clips to secure the

power cable onto a pole or the rails surrounding the platform. Ensure that there is no



126

excessively long distance between the equipment and the position where the power cableis secured.

Cabling of PGND Cablesl PGND cables for a base station must be connected to the same group of ground bars.l PGND cables must be buried in the ground or routed indoors. They should not be routed

overhead before they are led into the equipment room.l The exterior of the coaxial wire and the shield layer of the shielded cable must have proper

electrical contact with the metal surface of the equipment to which they are connected.l PGND cables and signal cables must be installed in an untangled and orderly manner. A

certain distance must be reserved between them to prevent interference from each other.l Fuses or switches must not be installed on the PGND cables.l Other devices must not be used for electrical connections of the PGND cables.l All the metal parts in the housing of the equipment must be reliably connected to the ground

terminal.

Cabling of E1 Cablesl E1 cables must not cross power cables, PGND cables, or RF cables when routed. If

transmission cables are routed with power cables, PGND cables, or RF cables in parallel,the spacing between them must be greater than 30 mm (1.18 in.).

l E1 cables are routed straightly and bound neatly with cable ties.l Sufficient slack is provided in E1 cables at turns.l Prevent the E1 cables routed in a cabinet from being pressed by the door of the cabinet, as

shown in Figure 12-3 and Figure 12-4.

Figure 12-3 Routing an E1 cable in a cabinet from the left side of the cabinet



127

Figure 12-4 Routing an E1 cable in a cabinet from the right side of the cabinet

Cabling of Fiber Optic Cables

l At least three persons are required for routing fiber optic cables. The cabling activities offiber optic cables are allowed only when qualified personnel and communication facilitiesare available.

l The operating temperature of fiber optic cables is from -40oC to 60oC (-40oF to 140oF). Ifthe actual temperature is beyond this scope, take protective measures or select another route.

l Circling and twisting of cables are prohibited.

l Do not bind a fiber optic cable at the position where it bends.

l Do not stretch, step on, or place heavy objects on fiber optic cables. Keep the fiber opticcables away from sharp objects.

l When fiber optic cables are routed, the extra length of the fiber optic cables must be coiledaround special devices, such as a fiber coiler.

l When coiling fiber optic cable, apply even strength. Do not bend the fiber optic cable withforce.

l Vacant optical connectors must be covered with dustproof caps.

l Prevent the fiber optic cables routed in a cabinet from being pressed by the door of thecabinet, as shown in Figure 12-5, Figure 12-6, Figure 12-7, and Figure 12-8.

12.4 Installing Transmission CablesThis section describes the procedures and precautions for installing transmission cables betweena cabinet and external transmission equipment.

12.4.1 Installing the E1/T1 CableThis section describes the procedure and precautions for installing the E1/T1 cable.



170

PrerequisitesEnsure that both ends of the E1/T1 cable are disconnected from any equipment. Then, solder aconnector to each of the E1/T1 cable during the same session.

Contextl Contact with Huawei engineers to confirm the following issues:


– Some cables of fixed lengths need to be shortened.l The principles for routing the E1/T1 cable are as follows:

– When not more than eight E1s are configured, one E1/T1 cable (on the SLPU side) isrouted along the inner right side of the cabinet.

– When more than eight E1s are configured, an additional E1/T1 cable (on the SLPU side)is routed along the inner left side of the cabinet.

l When the TMC11H uses the -48 V AC power supply, the connection and routing of theE1/T1 cable in this cabinet are the same as the cable connection and routing in the APM30Hthat is shown in Figure 12-41.

Procedure

Step 1 Connect one end of the E1/T1 cable to the OUTSIDE port on the UELP, as shown in Figure12-41.

NOTE

For the connections of E1/T1 cables, see section "Transmission Cable Connections" in the BTS3900A (Ver.D)Hardware Description.

12.4.2 Installing the FE/GE Ethernet cableThis section describes the procedure and precautions for installing the FE/GE Ethernet cable.



– Some cables of fixed lengths need to be shortened.l An FE/GE Ethernet cable is a shielded straight-through cable.l For the connections of FE/GE Ethernet cables, see section "Transmission Cable

Connections" in the BTS3900A (Ver.D) Hardware Description.l When the TMC11H uses the -48 V AC power supply, the connection and routing of the

FE/GE Ethernet cable in this cabinet are the same as the cable connection and routing inthe APM30H that is shown in Figure 12-43.

Procedure

Step 1 Route the FE/GE Ethernet cable through a cable bag into the cabinet.

Step 2 Install a ground clip for the FE/GE cable in a proper position within 1 m from the cable outletof the cabinet, as shown in Figure 12-42.1. Determine the position for grounding the FE/GE cable, and strip the sheath off the cable

for about 40 mm to expose the shield layer.2. Loosen the screws on the ground clip, and route the FE/GE cable through the clip.3. Make the shield layer of the FE/GE cable in full contact with the ground clip, and tighten

the M4 screws on the clip until the tightening torque reaches 1.2 N·m.

12.4.3 Installing the FE/GE Fiber Optic CablesThis section describes the procedure and precautions for installing the FE/GE fiber optic cables.



– Some cables of fixed lengths need to be shortened.l Single-mode optical modules are labeled as SM and multi-mode optical modules are labeled

as MM.l The puller of a single-mode optical module is blue. The puller of a multi-mode optical

module is black or gray.l The optical modules to be installed must match the rates of their corresponding ports.l An FE/GE fiber optic cable has an LC connector at one end and an FC connector, SC

connector, or LC connector at the other end.l SFP0 and FE/GE0 ports on the LMPT are used for one GE input. Therefore, they are not

used simultaneously.l SFP1 and FE/GE1 ports on the LMPT are used for another GE input. Therefore, they are

not used simultaneously.l The method of installing FE/GE fiber optic cables in an APM30H is the same as the method

of installing FE/GE fiber optic cables in a TMC11H. The following describes the procedurefor installing an FE/GE fiber optic cable in an APM30H.

NOTICEAn optical module may deteriorate if it is exposed to the air for more than 20 minutes. Therefore,you must insert a fiber optic cable into an unpacked optical module within 20 minutes.

Procedure

Step 1 Install an optical module, as shown in Figure 12-44.1. Remove the dustproof cap from the corresponding FE/GE optical port on the corresponding

BBU board.2. Remove the dustproof cap from the optical module.



174

3. Lower the puller on the optical module.

4. Insert the optical module into the FE/GE optical port.

5. Raise the puller on the optical module.
