TMC11H. When the IBBS200D/IBBS200T is stacked with the TMC11H, the TMC11H isstacked on the IBBS200D/IBBS200T.

l If auxiliary cabinets such as the IBBS200D/IBBS200T or TMC11H are required during aninitial site construction, the auxiliary cabinets are positioned on the left, and the primarycabinet is positioned on the right. If both the battery cabinet and the TMC are required, thebattery cabinet is positioned on the left of the main cabinet, and the TMC is stacked on thebattery cabinet or positioned on the left of the battery cabinet.

l Space must be reserved during an initial site construction for future capacity expansion. Inthe capacity expansion scenario, the original cabinets are not relocated while new cabinetsare added only from left to right. In a special scenario, new cabinets can be added fromright to left.

Cabinet Configurations of a Single-Mode or Dual-Mode Base StationA single-mode or dual-mode base station can be configured with only one BBU, which isinstalled in the APM30H. If 6 to 12 RFUs are configured, two APM30Hs are required. The BBUis installed in the basic APM30H, which is installed on the left.Table 2-4 describes the cabinet configurations of a single-mode or dual-mode base station tomeet requirements of different backup power configurations, space required for customerequipment, and carrier configurations.

3.2 BTS900A Power Distribution PrinciplesThis section describes the power distribution schemes for the BTS3900A (110 V AC or 220 VAC) and BTS3900A (48 V DC).

Power Distribution Scheme for the BTS3900A (110 V AC or 220 V AC)When the BTS3900A is supplied with 110 V AC or 220 V AC power, the AC power is convertedto DC power and distributed by the embedded power subrack unit (EPU) in the APM30H.After going through the EPU, an AC power input is divided into two AC power outputs asfollows:l One provides AC power for the service outlet unit (SOU).l One is connected to the junction box on the left of the cabinet, and divided into four AC

power outputs, which are then provided to the heater or heating film.The AC power input is converted by PSUs into DC power, which is supplied to the storagebattery cabinet, RFC, TMC11H, and other base station equipment.Figure 3-1 and Figure 3-2 show the power distribution schemes in the 220 V AC and 110 VAC power supply scenarios. Table 3-6 lists the specifications for the circuit breakers and fusesin the base station in the 220 V AC and 110 V AC power supply scenarios.

NOTE

When the 220 V AC three-phase power supply is used, the three AC power inputs do not need to be connectedin series using a short-circuiting bar. The power distribution scheme for this scenario is the same as that for the220 V AC single-phase power supply scenario.

As shown in Figure 3-1 and Figure 3-2, when the BTS3900A is supplied with AC power, threeDC power outputs from the APM30H are provided to RFC 1, RFC 2, and TMC11H separately.The RFC supplies power to the RFUs, fan box, and other components in the cabinet by usingthe DCDU-11A. The TMC11H supplies power to the transmission equipment, fan box, and othercomponents in the cabinet by using the DCDU-11C.Figure 3-3 shows the power distribution scheme for the RFC and TMC11H. Table 3-7 lists thespecifications for the circuit breakers in the RFC and TMC11H.

Power Distribution Scheme for the BTS3900A (48 V DC)When the BTS3900A is supplied with 48 V DC power, the external power supply is directlyled to the DC transfer box in the RFC, and then distributed to the DCDU-11A in the RFC andDCDU-11C in the TMC11H. The RFC provides power supply for the RFUs, fan box, and othercomponents in the cabinet by using the DCDU-11A. The TMC11H provides power supply forthe BBU, fan box, and other components in the cabinet by using the DCDU-11C.

4 BTS3900A Monitoring SystemAbout This Chapter

The BTS3900A monitoring system enables monitoring of all boards and components in thecabinet. If any board or component is faulty, an alarm is automatically reported. The UPEU andUEIU in the BBU collect monitoring signals from boards and components to achieveenvironment monitoring of the BTS3900A.

4.1 BBU Monitoring PortThe BBU houses the UPEU and UEIU for monitoring. Each board has two Boolean input portsand two RS485 input ports, and each Boolean input port receives four Boolean inputs.4.2 Monitoring Principles for the CabinetsThe BTS3900A cabinets are monitored by monitoring boards, such as the central monitoringunit type E (CMUE), HERT power monitoring interface unit (HPMI), and power monitoringunit (PMU). These boards collect alarms from sensors and fans, and then transmit the alarmsignals to the MON port on the BBU through the RS485 serial bus. This implements themonitoring of the cabinets.4.3 Customized Alarm InputsIf customer equipment needs to be monitored, customized alarms generated from the equipmentmust be reported to the BBU.

4.2 Monitoring Principles for the CabinetsThe BTS3900A cabinets are monitored by monitoring boards, such as the central monitoringunit type E (CMUE), HERT power monitoring interface unit (HPMI), and power monitoringunit (PMU). These boards collect alarms from sensors and fans, and then transmit the alarmsignals to the MON port on the BBU through the RS485 serial bus. This implements themonitoring of the cabinets.

Cabinet Monitoring Principles for a Single-Mode or Dual-Mode ScenarioA single-mode or dual-mode base station can be configured with only one BBU, which isinstalled in the APM30H. If two APM30H cabinets are configured, the BBU is installed in thebasic APM30H cabinet, which is installed on the left.Figure 4-2 and Figure 4-3 show the monitoring principles for the BTS3900A (110 V AC or220 V AC). Figure 4-4 shows the monitoring principles for the BTS3900A (48 V DC).

NOTE

Devices monitored by the CMUE, HPMI, and PMU are not shown in the following figures. For details,see the descriptions about the monitoring boards. For details about the monitoring functions of theenvironment monitoring unit type A (EMUA), see 4.3 Customized Alarm Inputs.l For details about the functions of monitoring ports on the CMUE, see CMUE. The CMUE is installed

in the APM30H, TMC11H, RFC, IBBS200D, and IBBS200T.l For details about the functions of monitoring ports on the HPMI, see HPMI. The HPMI is installed

in the APM30H (AC) and TMC11H. Ports on the HPMI in the TMC11H are reserved for later use.l For details about the functions of ports on the PMU, see PMU. The PMU is installed only in the

APM30H (AC).l For details about the positions for installing the CMUE, HPMI, PMU, and EMUA in each cabinet,

see 2.2 Structure of the BTS3900A Cabinets.

NOTE

l If any of the following devices is not configured at a site, the monitoring signal cable can be directlyconnected to the lower-level device. For example, if the GSM antenna and TMA control module(GATM 0) and GATM 1 are not configured in Figure 4-2, the monitoring signal cables can be directlyconnected to the CMUE through the MON0 and MON1 ports on the BBU.

l If any of the following cabinets is not configured at a site, the monitoring signal cable related to thiscabinet can be directly connected to the lower-level cabinet. For example, if No. 2 TMC11H is notconfigured in Figure 4-3, the monitoring signal cable can directly connect the COM_OUT port on theCMUE in No. 0 RFC and the COM_IN port on the CMUE in No. 1 RFC.

l All monitoring signal cables in the cabinets and between the APM30H and RFC are connected beforedelivery. You only need to connect monitoring signal cables between other cabinets. For details aboutconnections of all the monitoring signal cables in different cabinets, see 6.3.4 Monitoring Signal CableConnections.

4.3 Customized Alarm InputsIf customer equipment needs to be monitored, customized alarms generated from the equipmentmust be reported to the BBU.

Monitoring Board ConfigurationWhen an alarm is generated from customer equipment, the alarm must be reported to the BBU.The configurations of monitoring boards in the BTS3900A depend on the number of customizedalarms, as listed in Table 4-2.

Table 4-2 Monitoring board configurations of the BTS3900ANumber of Customized Alarm Inputs Monitoring Board Configuration1 to 16 UPEU+UEIU17 to 32 EMUA

NOTE

If the number of customized alarms ranges from 1 to 16, a signal lightning protection unit (SLPU) mustbe configured because the SLPU provides protection to the alarm signals before the signals can betransmitted to the BBU.

Customized Alarms Collected by the UPEU or UEIUEach UPEU or UEIU in the BBU supports eight Boolean alarm inputs. A maximum of twoUPEUs or UPEU+UEIU can be configured for the BBU, which means there are 16 Booleanalarm inputs. This method can be used for the configuration of less than 16 customized alarminputs.If using this method, connect the device to be monitored to the SLPU for surge protection, andthen connect the device to the EXT_ALM port on the BBU, as shown in Figure 4-5.

NOTEThe SLPU is configured with two USLP2s by default before delivery when it is used as an alarm signalprotection unit. If a BBU is configured with one UPEU, the UPEU must be installed only in the lower slot.In this case, the USLP2 in the upper slot of the SLPU is not used.

Customized Alarms Collected by the EMUAThe EMUA can be configured for the DBS3900 that requires more than 16 Boolean alarmsignals. Each EMUA supports 32 Boolean alarm inputs and two RS485 signal inputs.



34

Customized alarms are transmitted to the EMUA that is connected to the PMU. Then, the PMUreports the alarms to the CMUE, which transfers the alarms to the BBU through the MON port.For details about cable connections, see Figure 4-6.
