l (1) When a CCU is configured, the ELU is installed in the position illustrated by "6." When no CCUis configured, the ELU is installed in the position illustrated by "5."

l (2) When the IBBS700T cabinet is used with an APM30H (Ver.D) cabinet, no CCU is required. Whenthe IBBS700T cabinet is used with a BTS3900AL (Ver.A) or TP48600A-H17B1 cabinet, a CCU isrequired.

l (3) The storage batteries provide current of 300 Ah, 450 Ah, or 600 Ah for a single cabinet and providecurrent of 150 Ah or 300 Ah for each one in a cabinet combination.

l A battery temperature sensor is configured in the cabinet by default. For details about the position ofthe battery temperature sensor in the cabinet, see Temperature Sensor.

2.2 BTS3900A (Ver.D) Configured with RFUs but WithoutRRUs

When only RFUs are configured, a BTS3900A supports different cabinet configurations in 110V AC, 220 V AC, or -48 V DC power supply scenarios.

Cabinet Configuration PrinciplesMaximum configuration principles for a single sitel A BTS3900A site can be configured with a maximum of 12 RFUs.l A BTS3900A site can be configured with a maximum of two cabinet combinations (one

cabinet combination consists of one APM30H and one RFC). The two cabinet combinationsmust be installed side by side with a clearance of 40 mm (1.57 in.) between them.

l When a site is configured with more than six RFUs and only one IBBS200D or IBBS200T,the IBBS200D or IBBS200T must be configured with at least two battery packs consistingof 92 Ah storage batteries to avoid overcurrent of a single battery pack during thedischarging.

Principles for stacking and combining cabinets



18

l An IBBS200D or IBBS200T can be stacked only with an IBBS200D, IBBS200T, orTMC11H. When the IBBS200D or IBBS200T is stacked with the TMC11H, the TMC11His stacked on the IBBS200D or IBBS200T.

l An RFC can be stacked only below the APM30H or TMC11H.l If auxiliary cabinets, such as the battery cabinet IBBS200D/IBBS200T or transmission

cabinet TMC11H, are required during an initial site construction, the auxiliary cabinets arepositioned on the left side of basic cabinets. If both the battery cabinet and transmissioncabinet are required, the battery cabinet is positioned on the left side of the basic cabinet,and the transmission cabinet is stacked on the battery cabinet or positioned on the left sideof the battery cabinet.

l During an initial site construction, space must be reserved for capacity expansion. Unlessotherwise stated, the original cabinets remain in the original positions and new cabinets areadded to the right side of original cabinets during capacity expansion. In a special scenario,new cabinets can be added to the left side of original cabinets.

l A cabinet combination of one APM30H and one RFC is configured with one BBU bydefault. This cabinet combination can be configured with a maximum of two BBUs, andthe power consumption of all BBU boards cannot exceed 1000 W. This principle appliesto a new or expansion scenario.

Cabinet Configurations of a Single- or Dual-Mode BTS3900AA single- or dual-mode base station is configured with only one BBU, which is installed in theAPM30H or TMC11H. When seven to twelve RFUs are configured, two RFCs are required.

When a site is supplied with 110 or 220 V AC power and does not require backup power, thecabinet configurations of a single- or dual-mode base station with different requirements of spacefor customer equipment and carrier configurations are shown in the following figure.

12.1 Cabling RequirementsCables must be laid out according to the specified cabling requirements to prevent signalinterference.

NOTE

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

General Cabling Requirements

Bending radius requirements

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

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

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

l The bending radius of a fiber optic cable is at least 20 times of its diameter, and 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 diameter.

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

Cable binding requirements

l Cables of the same type must be bound together.

l Different types of cables must be separately laid out 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 excess of the indoor cable ties is cut off. The excess of 5 mm (0.197 in.) of the outdoorcable 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 requirements

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 or 3.937 in. is recommended) between equipment andcables especially at the cable curves to protect the cables and equipment.

Indoor cabling requirements

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



154

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 greater 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 Apply waterproof treatment 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 include AC power cables, transmission cables, and cables laidout underground.

l When routing cables through tubes on the ground below the cabinet, put a 30 mm to 50mm (1.18 in. to 1.97 in.) length of the tubes into the base of the cabinet but do not put thetubes into the cabinet. Use waterproof tape or waterproof silicon gel to block both ends ofthe tubes and use sheet metal tabs to secure the tubes to the cable holes in the base.

l When routing cables through tubes along a metal cable trough below the cabinet, do notput the tubes into the base of the cabinet but cover the cable trough and connect the tubesto the cable holes in the base.

l Use clips to secure cables outdoors. For the method of installing a clip, see the installationguide delivered with the clip.

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

l When fastening cables with a clip, ensure that the cables are aligned neatly and are routedthrough the holes in the clip. Do not stretch the cables too tightly.

NOTE

There are two types of clips: 3-hole clip and 6-hole clip, which are described as follows:

l A 3-hole clip is shown by illustration a in the following figure. It is often used to fasten feeders.

l A 6-hole clip is shown by illustration b in the following figure. It is often used to fasten power cables andCPRI fiber optic cables.

Special Cabling Requirements

Cabling of power cables

l 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 connectorsor soldering joints to lengthen the cables.

l Cables can only be laid out under well-planned instructions. The cabling activities of fiberoptic cables are allowed only when qualified personnel and communication facilities areavailable.

l Do not circle and twist cables.



157

l After routing a DC power cable onto the platform on a tower, route it along the shortestpath 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 thepower cable onto a pole or the rails surrounding the platform. Ensure that there is noexcessively 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.

l The external conductor of the coaxial wire and the shield layer of the shielded cable musthave proper electrical contact with the metal surface of the equipment to which they areconnected.

l PGND cables and signal cables must be installed separately. A certain distance must bereserved between them to prevent interference from each other.

l Switches or fuses 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 groundterminal.

Cabling of E1 cablesl E1 cables must not cross power cables, PGND cables, or RF cables when laid out. If

transmission cables are laid out 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 lined up straight and bound neatly with cable ties.

l Sufficient slack is provided for E1 cables at turns.

l E1 cables must not be pressed by the door of the cabinet when routed, as shown in thefollowing figure.

Figure 12-4 E1 cables routed in the cabinet

Cabling of fiber optic cablesl At least three people are required for laying out fiber optic cables. The cabling activities

of fiber optic cables are allowed only when qualified personnel and communicationfacilities are available.



158

l The operating temperature of fiber optic cables ranges from -40ºC to +60ºC (-40ºF to+140ºF). If the actual temperature is beyond this range, take protective measures or selectanother route.

l Do not circle and twist cables.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 optic

cables away from sharp objects.l When fiber optic cables are routed, the excess of the fiber optic cables must be coiled around

special devices, such as a fiber coiler.l An unarmored fiber optic cable must be bound using binding straps. If a fiber optic patch

cord needs to be secured in a cabinet or a piece of equipment, use binding straps to bind itand then use cable ties to secure the binding straps to the cabinet or equipment. Ensure thatthe fiber optic cables can flexibly move in the cable ties. Do not bend the fiber optic cablessharply. The following figure shows how to bind the fiber optic cables correctly.

Figure 12-5 Binding fiber optic cables

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

with force.l Unused optical connectors must be covered with dustproof caps.l The fiber optic cables must not be pressed by the door of the cabinet when routed, as shown

in the following figures.
