3 BTS3900L Hardware Configuration NOTE

(1) If both high-power RFUs and low-power RFUs exist in the same base station, the power configuration for high-power RFUs will apply for the base station. (2) If possible, it is suggested to configure the base station with the power configuration for maximum high-power RFUs so as to satisfy all scenarios. If the power configuration has to be in accordance with actual scenarios, the circuit breaker and power cables need to be upgraded in case of base station extension. (3) The power configuration applicable for the scenarios with higher power consumption is also applicable for the scenarios with lower power consumption. (4) The circuit breakers for high load capability are applicable to those for low load capability. The sequence of load capability for circuit breakers is: 1 x 160A > 2 x 80A > 2 x 63A > 1 x 100A > 1 x 80A > 1 x 63A. (5) The power consumption of inner transmission is ignored for the circuit breakers of indoor macro base station. (6) High-power RFUs include: LRFUe, WRFUd, and MRFUd. (7) Low-power RFUs include: DRFU, GRFU, WRFU, MRFU, CRFU, LRFU. and MRFU V3. (8) If two external power inputs are supplied, the following requirements must be met: l

The two power inputs must be supplied by the same power cabinet.

l

The circuit breakers used for the two power inputs have the same model and specifications.

l

The power cables for the two power inputs must have the same cross-sectional area and length.

l

When powering on the base station, turn on the two circuit breakers of power input before turning on the circuit breakers for all the RFUs. When powering off the base station, turn off the circuit breakers for all the RFUs before turning off the two circuit breakers of power input.

(9) One DCDU-11A can supply a maximum of three power inputs for two BBUs. The cabinet can be configured with a maximum of two BBUs, one with power consumption of 650 W and the other with power consumption of 360 W. If an additional DCDU-11A is configured, the cabinet can be configured with two BBUs both with power consumption of 650 W. (10) If two BBU3900s are configured, the second BBU3900 shall obtain power from a power cabinet outside of the DCDU-11A in the base station that the second BBU3900 installed.

(11) The power cables for the fan unit or BBU must be reconnected. For details, see the BTS3900L (Ver.C) Installation Guide.

3.2.2 Power Distribution This section describes the power distribution mode of the BTS3900L cabinet. The external power equipment supplies -48 V DC power to the DCDU-11A of the BTS3900L cabinet, and the DCDU-11A feeds power to each module in the cabinet. Figure 3-2 shows the principles of the power distribution.

Issue 07 (2012-02-25)

Figure 3-2 Power distribution of the BTS3900

3.3 BTS3900L Monitoring System The BTS3900L monitoring system monitors all boards and components in the cabinet. If any board or component is faulty, an alarm is reported automatically. The alarm signals are collected both inside and outside the cabinet by the UPEU, UEIU, or EMU, so that the entire site can be monitored.

3.3.1 BBU Monitoring Port The BBU houses the UPEU and UEIU for monitoring. Each board has two Boolean input ports and two RS485 input ports, and each Boolean input port receives four Boolean inputs. Figure 3-3 shows the slot assignment for the UPEU and UEIU.

3.3.2 Monitoring Principles of the Cabinet A monitoring board is connected to the MON port on the BBU. It collects the alarms of all components and reports the alarms to the BBU by using the RS485 serial bus. For details about the monitoring ports on the FMU, see FMU. Issue 07 (2012-02-25)


13



Two BBUs are required in an evolution from a single-mode or dual-mode scenario as shown in Figure 1 to a triple-mode scenario as shown in Figure 2 or in a new triple-mode scenario as shown in Figure 2. The BBU installed in the upper part of the cabinet is BBU0, and the BBU installed in the lower part of the cabinet is BBU1. In a triple-mode scenario, all the monitoring equipment is connected to BBU0. The monitoring principles of the triple-mode scenario are the same as the dual-mode scenario. NOTE

The BBU 0 is main BBU, and the BBU 1 is extension BBU.

If any device in the figure is not configured at the site, neither need its cable to be installed. Figure 3-4 Monitoring system for the BTS3900L cabinet (triple-mode scenario)

NOTE

For details about how to monitor the EMU, please refer to 3.3.3 Customized Alarm Inputs.

3.3.3 Customized Alarm Inputs Customized alarms must be reported to the BBU. The customized alarms are reported to the BBU by any of the following methods: l

The alarms are collected by the UPEU or UEIU in the BBU.

l

The alarms are collected by the EMU.

For details about the configuration of the customized alarms, see the related initial configuration guide. Issue 07 (2012-02-25)

After the UPEUc is replaced by the UPEUa, the base station power consumption data monitored by the network management system will change. The power consumption data does not only depend on the output power but also on the data collection method. The UPEUc and UPEUa use different methods for power consumption data collection. Therefore, the decrease in the power consumption shown in the network management system after the UPEUc is replaced by the UPEUa does not necessarily reflect the actual decrease of power consumption.

Panel Figure 4-54 shows a MRFU V3 panel. Figure 4-54 MRFU V3 Panel

Function The functions of MRFU V3 are as follows: l

Modulates and converts the signals to the TX band by up-converting the intermediate frequency (IF) signals, filters and amplifies the signals and then transmits the signals to the antenna through the duplexer.

l

Receives radio frequency (RF) signals from the antenna system, down-converts the signals to IF signals, and then transmits them to the baseband unit (BBU) after an amplification, analog-to-digital conversion, digital down-conversion, matched filtering, and Automatic Gain Control (AGC).

Transmission Cable Connections for a GSM+UMTS Base Station in Common Transmission Mode When a GSM+UMTS base station works in co-transmission mode, TDM co-transmission or IP co-transmission can be used. Based on the IP co-transmission, the GSM+UMTS base station can implement route backup. That is, four FE ports on the GTMU and LMPT panels are used. Of the four FE ports, two FE ports of one type are used for interconnection, and the FE ports of the other type are connected to the transport network.

TDM Common Transmission Figure 5-15 shows the transmission cable connection for a GSM+UMTS base station in TDM common transmission mode when the E1/T1 port on the GTMU serves as the shared port to connect to the BSC and RNC.

Route Backup Mode with IP Common Transmission In a GSM+UMTS base station, the route backup mode with IP common transmission has the following characteristics: l

IP transmission is applied. The GTMU and WMPT are connected to the BSC and RNC respectively using the active channel.

l

The GTMU and the WMPT are interconnected using FE ports on their panels.

l

If the active channel is faulty, the standby channel takes over. After the active channel is restored, the route is switched back to the active one.

l

The bandwidth required by UMTS services is larger than the processing capability of the GSM standard transport network. Therefore, when the standby channel is used, the Quality of Service (QoS) of only high-priority data flows can be guaranteed.

In a GSM+UMTS base station, the route backup mode with IP common transmission has the following limitations: l

The route backup function is not applicable when the base station uses the IP over E1 common transmission.

l

The route backup mode is not applicable to the ports on the UTRPs for GSM or UMTS transmission. It is applicable only to the ports on the GTMU and WMPT panels.

l

In route backup mode, the FE ports of one type on the GTMU and WMPT panels are interconnected. The FE ports of the other type on the two boards are connected to the BSC and the RNC.

Transmission Cable Connection in the UMTS+LTE Base Station in Route Backup Transmission Mode A UMTS+LTE base station implements IP co-transmission based on the interconnection between the FE ports (optical or electrical type) on the WMPT and LMPT panels. Based on the co-transmission, route backup can be implemented. That is, four FE ports on the WMPT and LMPT panels are used. Of the four FE ports, two FE ports of one type are used for interconnection, and the FE ports of the other type are connected to the transport network. In a UMTS+LTE base station, the route backup transmission mode has the following characteristics: l

IP transmission is applied. The WMPT and LMPT are connected to the transport network through the primary channel.

l

The WMPT and the LMPT are interconnected through FE ports on their panels.

l


l

The bandwidth required by LTE services is larger than the processing capability of the UMTS standard transport network. Therefore, when the secondary channel is used, the Quality of Service (QoS) of only high-priority data flows can be guaranteed.

In a UMTS+LTE base station, the following limitations on the route backup transmission mode apply: l


l

The route backup transmission mode is not applicable on the ports on the UTRPs for UMTS and LTE transmission. It is applicable only on the ports on the WMPT and LMPT panels.

l

In route backup transmission mode, the FE ports of one type on the WMPT and LMPT panels are interconnected. The FE ports of the other type on the two boards are connected to the transport network.

FE Optical Ports for Interconnection and FE Electrical Ports Connected to the Transport Network Figure 5-56 shows the transmission cable connections for a UMTS+LTE base station in route backup transmission mode when the FE optical ports on the WMPT and LMPT are interconnected and the FE electrical ports on the two boards are connected to the transport network.

Transmission Cable Connection in the UMTS+LTE Base Station in Hybrid Transmission Mode A UMTS+LTE base station implements IP co-transmission based on the interconnection between the FE ports on the WMPT and LMPT panels. Based on the co-transmission, hybrid transmission can be implemented. That is, the UMTS E1/T1 port and LTE FE/GE port are used as shared ports for data transmission. The E1/T1 port is used to transmit the services with high QoS requirements, such as CS services. The FE/GE port is used to transmit the services with low QoS requirements, such as PS services. The UMTS E1/T1 port and the LTE FE/GE port are used for data transmission in a UMTS+LTE base station in hybrid transmission. When the UMTS FE/GE port and the LTE FE/GE port are used for data transmission, hybrid transmission is not applicable.
