General Product Information1 IntroductionThe General Product Information provides general information onunconfigured radio base stations. Refer to the RBS 884 Site EngineeringManual for descriptions of the available working base station configurationsand for information on RBS interfaces (for instance, power, transmission,and antennas).2 FeaturesThe RBS 884 Series is a series of products in the CMS 8800 family. Theproducts in the RBS 884 Series are fully featured modular RBSs for boththe analog AMPS EIA 553 and the digital D-AMPS EIA IS 136 systems(Advanced Mobile Phone System Electronics Industry Association 553system and Digital American Mobile Phone System Electronics IndustryAssociation Interim Standard 136 system).A base station in the RBS 884 Series can support one, two, or three cells. Acell is a defined area covered by one antenna system, and each cell has onecontrol channel for digital or one for analog, or both. There is one cell at anomni site, and one to three cells at a sectorized site.The RBS 884 Series utilizes multi-mode, multi-functional transceivers(TRXs). The same hardware TRX module can be used for analog and digitalvoice, control and monitoring purposes.The hot repair capability allows replacement of defective units when poweris still applied.The RBS 884 Series is designed for remote control monitoring allowingcontrol and fine tuning of all functions and parameters, such as power output,frequencies, and switching of redundant units from the MSC.A Radio Frequency Test Loop (RFTL) is an optional feature that enablesprecise output power settings, Voltage Standing Wave Ratio (VSWR) alarm,and Receive Signal Strength Indicator (RSSI) test measurements.The device software is stored in non-volatile memory within the RBS, andthe control part software is downloaded from the MSC, which ensures ashort time to service at power-up.1/1551 AE/LZB 119 4239 Uae Rev PRELIM 2001-03-15 2-3

System Description1 IntroductionThis section provides an overview of the RBS 884 Macro with MCPA, 1900MHz radio base station (RBS). Areas covered include system architecture,configuration, functional units and technical specifications.This RBS supports digital TDMA and operates at 1850–1990 MHz (dividedinto 6 sub-bands) and is part of the Mobile Base Station (MBS) subsystem. Ithandles the communication between a Mobile Switching Center (MSC) andMobile Stations (MSs). This radio base station also supervises the quality ofradio transmission during a call in progress. The MBS consists of hardwareand software located in the MSC as well as in the RBS.The Macro with MCPA, 1900 MHz system is available in the followingconfigurations:• 1, 2, and 3 Sector x 15 carriers• 1, 2, and 3 Sector x 23 carriers• 1, 2, and 3 Sector x 31 carriers2/1551-AE/LZB 119 4239 Uae Rev A 2001-03-15 3-3

General Overview of RBS 884 ConfigurationThe Group Switch (GS) at the MSC is responsible for switching calls betweensubscriber terminals. The calls can be between two mobile subscribersor between a mobile subscriber and a subscriber in the public telephonenetwork. The RBS contains several regional processors which are controlledby and work with the central processor. The regional processors control theswitch and the transceivers (TRXs) in the base station.

The control signals for the RBS are carried on one timeslot of the PCM link, and are ended by the Signal Terminal Receiver (STR).A set of Extension Module Regional Processor Speech Bus Interfaces(EMRPSs) is used to control the devices on a load sharing basis.Communication Links (C-links) connect device equipment (TRX, ALM,RFTL, and TIM) to the Radio Transceiver Terminals (RTTs).A Node Clock Time Switch (NTSW) connects control paths from theEMRPSs to the devices. The time switch also routes the traffic data on pathsset up between a time slot on an ETB and a device connected to an RTT. Thetime switch is controlled by a dedicated EMRP.The received RF signal is split to all Transceiver modules (TRXs) by thePower Splitters (PSPs) and the Power Splitter backplane in the TransceiverCabinet (TCB).The RF output from the TRXs are connected to the HCC.Figure 3-7 on page 3-11 is an example of unit interaction in the HCC andANPC.

The PSP8+ in TCB-1 splits eachbranch into four outputs that are connected to the RF backplane.5.2.3 RF BackplaneThe RF Backplane, also called Power Splitter backplane, feeds the TRXswith receive signals. Incoming signals from the PSP outputs are connected tothe RF backplane. The backplane also splits each signal to feed the TRXs.5.2.4 Power and Fan Connection Board (PFCON)The PFCON filters and bypasses power to the TRXs and to the fan. It alsoconnects the air frame sync to the backplane for distribution to each TRX.5.2.5 Data Connection Board (DCON)The DCON provides the C-link connections for up to eight TRXs. TheC-links come from the RTT units in the CRI.5.2.6 Digital Verification Receiver (DVER)The DVER TRX is used for digital signal verification and is assigned to theTRX fitted in the last TRX position of the first TCB in each sector.5.3 Antenna Near Part Cabinet (ANPC)A Macro with MCPA RBS module (omni site) contains one ANPC thatfunctions as the radio transmitter/receiver interface. It also includes externalalarm, test, and calibration functionality.The ANPC filters, amplifies (in the receive path), and monitors the RFsignal. Other functions include looping radio signals, output and reflectedpower measurement, and RSSI calibration.The Macro with MCPA, 1900 MHz ANPC contains the followingcomponents:• Multicoupler (2)• Receiver Bandpass Filter (1)• Radio Frequency Test Loop• Timing Module (2 – Sector 1 only)3-28 2/1551-AE/LZB 119 4239 Uae Rev A 2001-03-15

There are two MCs for each sector for improvedreception through diversity.5.3.2 Receiver Bandpass Filter (RXBP)The RXBP filters the receive band. It comprises two bandpass filters, onefor each branch. The RX inputs are connected to the antenna feeders. TheRXBP also includes a directional coupler for connection to the RFTL.5.3.3 Radio Frequency Test LoopThe RFTL has a C-link connection to the CRI for control. The RFTLprovides measurement of forward and reverse output power, alarmsupervision of the Voltage Standing Wave Ratio (VSWR), and ReceiveSignal Strength Indicator (RSSI) measurement.2/1551-AE/LZB 119 4239 Uae Rev A 2001-03-15 3-29

System Description5.3.4 Timing Module (TIM)The TIM supports separate clocks for network synchronization and carrierfrequency stabilization.5.3.5 Power Connection BoardThe Power Connection Board connects power to the ANPC.5.3.6 Alarm Module (ALM)The Alarm Module has 16 internal alarm inputs (for instance, fan and MCfailure) and 32 external alarm inputs (for instance, fire alarms and intrusionalarms). The ALM is controlled over a C-link by the CRI.5.4 Hybrid CombinerThe Hybrid Combiner cabinet contains two 16:1 combiners and one 2:1combiner to connect 32 TRXs to one transmit antenna. The 16:1 combines16 TRX outputs (with minimum insertion loss while providing suffcientisolation between the TRXs) and feeds the signal to a 2:1 combiner. Atotal of 32 carriers feed the Multi-Carrier Power Amplifier (MCPA).TheTransmit Bandpass Filter (TXBP) and the Measurement Coupler Unit(MCU) are located in the MCPA rack. The combiner is also equipped with a–40 dB sample port.RF Out 1-32-40dB Sample PortIn 1-16In 17-32Figure 3-19. Hybrid Combiner Unit3-30 2/1551-AE/LZB 119 4239 Uae Rev A 2001-03-15

$System Description5.5 Transmit Bandpass Filter (TXBP)The Transmit Bandpass Filter (TXBP) attenuates the high level ofout-of-band emissions associated with the MCPA. The TXBP consists of aneight-pole bandpass filter designed for 1930–1990 MHz. The TXBP has anRF inlet from the MCPA and an output which is fed to the MCU.TXBP/MCU1234AMPLIFIER1234AMPLIFIERON OFFON OFFON OFFON OFF1234AMPLIFIER1234AMPLIFIERON OFFON OFFON OFFON OFFFigure 3-20. TXBP and MCU5.6 Measurement Coupler Unit (MCU)The Measurement Coupler Unit (MCU) measures reflected and forwardpower. It diverts a fraction of the forward and reflected transmit signals tothe RFTL. The TX input is connected to the TXBP and the TX output isconnected to the antenna feeder. The MCU contains a low-pass filter toattenuate harmonics.2/1551-AE/LZB 119 4239 Uae Rev A 2001-03-15 3-31$
