3 Configurations of the Matched Cabinets

When the DBS3900 is installed outdoors, multiple matched cabinets must be configured to meetthe backup power, transmission, and capacity requirements. Different types of cabinet can becombined to form the DBS3900, providing multiple outdoor solutions.

Cabinet Configuration PrinciplesNOTEIn the following description, the APM is the APM30, APM30H (Ver. A), and APM30H (Ver. B). TheTMC falls into the categories of the TMC, TMC11H (Ver. A), and TMC11H (Ver. B).

l A single DBS3900 can be configured with a maximum of 12 RRUs. If there are more than12 RRUs, they must be configured in different base stations.

l A single APM or TMC can provide power to a maximum of six RRUs.l A single APM30/APM30H (Ver. A) can be configured with only a single TMC/TMC11H

(Ver. A) and a maximum of one IBBS200T.l A single APM30H (Ver. B) can be configured with only a single TMC11H (Ver. B) and a

maximum of two IBBS200Ds/IBBS200Ts.l A maximum of six power cables and twelve 2-core optical cables can be led out from a

single APM.l A single DCDU supplies power to a maximum of six RRUs.l The APM or TMC can be installed on the floor or stacked on the battery cabinet.l The BBC/IBBS200D/IBBS200T can be stacked on each other or placed under a TMC.

When the BBC/IBBS200D/IBBS200T is stacked with the TMC, the BBC/IBBS200D/IBBS200T is stacked on the TMC.

l If auxiliary cabinets such as the battery cabinet or TMC are required during an initial siteconstruction, the auxiliary cabinet is positioned on the left, and the primary cabinet ispositioned on the right. If both the battery cabinet and the TMC are required, the batterycabinet is positioned on the left of the primary 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.

l If backup power is required for the BBU, two UPEUs rather than UPEU+UEIU are configured.l The analog values can be monitored only by the EMUA.l Two USLP2s and one SLPU are delivered in a package.l The EMUA with sensors is configured according to site requirements for the indoor DBS3900.

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 6-14.

8.2.11 Transmission Cable Connections in the Outdoor GSM+UMTS Base Station in Route Backup Transmission Mode

A GSM+UMTS base station implements IP co-transmission based on the interconnectionbetween the FE ports (optical or electrical type) on the GTMU and WMPT panels. Based on theco-transmission, route backup can be implemented. That is, four FE ports on the GTMU andWMPT panels are used. Of the four FE ports, two FE ports of one type are used forinterconnection, and the FE ports of the other type are connected to the BSC and RNC.




Issue 03 (2010-10-25)

In a GSM+UMTS base station, the route backup transmission mode has the followingcharacteristics:

l IP transmission is applied. The GTMU and WMPT are connected to the BSC or RNCthrough the primary channel respectively.

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

l If the primary channel is faulty, the secondary channel takes over. After the primary channelis restored, the route is switched back to the primary one.

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

In a GSM+UMTS base station, the following limitations on the route backup transmission modeapply:

l The route backup function is not applicable when the base station uses the IP over E1transmission.

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

l In route backup transmission mode, the FE ports of one type on the GTMU and WMPTpanels are interconnected. The FE ports of the other type on the two boards are connectedto the BSC and the RNC.
