RBS 884 Pico (1900 MHz) ComponentsThe RBS 884 Pico (1900 MHz) consists of a CRI that interfaces with remoteRadio Heads. The product is used for spot coverage in larger 1900 MHzsystems or for indoor wireless systems.The RBS 884 Pico (1900 MHz) control hardware is installed in a standard19-in equipment rack or an optional floor mount cabinet. The radio hardwareis installed on a wall or other vertical surface separate from the CRI hardware.With leased T1/E1 connections between the CRI and Radio Heads, the CRIcan be centrally located and the Radio Heads can be installed in separatebuildings. With non-leased connections between the CRI and Radio Head,the maximum cable loss between the Radio Head and the CRI is 30 dB. Thiscable loss restriction allows the first Radio Head to be located 800 m to1000 m from the CRI (as measured by cable length).To comply with FCC RF exposure requirements, the external antennas usedwith this device must be mounted to provide a minimum separation distanceof 20cm (8 inches) from all persons, with the antenna gain not exceeding 14dBi. Amplifiers and boosters are not permitted.2-4 1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05

System Description2.1 RBS 884 Pico Call Path and Signaling2.1.1 Control SignalingControl signaling for the RBS 884 Pico (1900 MHz) system is as follows:•The MSC central processor sends the control signal to the SignalingTerminal Central (STC) unit.•The STC unit converts the signal format and sends the signal to theExchange Terminal Circuit (ETC).•The ETC inserts the control signal into a time slot on the PCMT1/E1 link to the base station CRI.•The ETB extracts the control signal and sends it to the STR.•The STR converts the information back to processor format andoutputs it on the Extension Module Regional Processor Bus(EMRPB).•The EMRPB connects the processing units (EMRP and EMRPSs).–The EMRP controls the CRI hardware units, including theRITSW, ETB, and ELI.–The EMRPS (through the ELI) controls the TRXs in the RadioHead. The T1/E1 network connection with Link AccessProtocol D (LAPD) provides error detection and retransmission.2.1.2 Speech SignalingSpeech signaling for the RBS 884 Pico (1900 MHz) system is as follows:•The Public Switched Telephone Network (PSTN) sends a speech ordata signal to the Group Switch (GS) at the MSC.•A digital call is processed by the MSC as follows:–Routed to the Transcoder Rate Adaptation Board (TRAB)–Converted into compressed format used in the air interface withAlgebraic Code Excited Linear Prediction (ACELP)2-6 1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05
System Description–Combined with two other voice paths that share the samefrequency–Routed to the correct ETC•The signal is sent over a T1/E1 line to the base station CRI where itis routed to the following units:–ETB–RITSW–ELI•The ELI unit communicates with TRXs in the Radio Head through aT1/E1 line.•In the Radio Head, the RHI receives the signal and routes it to thecorrect TRX, where it is converted to RF. The RF is then filtered andcoupled to the antenna(s) for transmission.2.2 SynchronizationSynchronization is necessary to ensure a stable carrier frequency referenceand error-free transmission between the RBS and the MSC.Jitter and wander introduced by the T1/E1 line between the CRI and theRadio Head is filtered out by the Radio Head Phase Locked Loop (PLL). Thefrequency accuracy of the Radio Head is better than 0.1 ppm at the presenceof maximum wander (138 UI), provided that the reference frequency for thePLL is traceable to a long-term Stratum 2 clock reference from the network.With non-leased or proprietary connections between the CRI and the RadioHead, the ELI unit is connected to the incoming MSC PCM Stratum 2reference. The T1/E1 connectionontheETBunitiscabledtothefirstELIunit. The first ELI unit uses the PCM reference to provide the transmit clockfor the PCM interface to the Radio Heads. The reference from the first ELIunit is passed to the other ELI units through the ETB-ELI Sync Cable.3 ArchitectureThe RBS 884 Pico (1900 MHz) controls and handles communicationbetween the MSC and the mobile stations. The configuration of the Picoequipment depends on the following:1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05 2-7

CRI InterconnectionsThe following paragraphs describe the hardware units used in the RBS 884Pico (1900 MHz) CRI magazine.3.2.1.1 DC/DC Power Converter UnitsThe CRI has two DC/DC converter units that supply power to the CRIsubrack. The converter units receive power from a single +24 Vdc powerfeed and convert it to ±5 Vdc for use by the CRI boards.1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05 2-17
System DescriptionEach DC/DC converter unit is capable of powering the entire CRI subrack incase of failure of one of the units. When both units are operational, theyshare the load. The EMRPSs have onboard DC/DC converters.3.2.1.2 Exchange Terminal Board (ETB)The ETB unit provides a T1/E1 network interface to the MSC. It is availablein a 24 time slot T1 version (ETB24) or a 32 time slot E1 version (ETB32).The physical T1/E1 interface is a quarter-plug connector on the frontpanel of the ETB. The unit provides frame synchronization and time slotextraction/generation of the T1/E1 signal.The ETB routes the speech DS0 signals to the RITSW overtheCRIbackplane. The ETB extracts base station control information from a singleT1/E1 time slot. This signal is routed to the STR. The ETB also extracts the8 kHz frame clock from the network interface link. The frame clock providesthe Carrier Frequency Reference (CFR) to the RITSW.3.2.1.3 Signaling Terminal Regional (STR)The STR is a protocol converter that communicates with the STC in theMSC. Communication with the MSC is through a single DS0 time sloton the MSC-CRI span. This time slot is routed from the span to the STRby way of the ETB. In addition, the STR generates the EMRPB interfacewithin the CRI.3.2.1.4 Extension Module Regional Processor (EMRP)The EMRP is controlled by the MSC. In turn, the EMRP controls the ETB,ELI, and RITSW through the backplane Device Control Bus (DEVCB). TheEMRP communicates to the MSC through the EMRPB provided by the STR.The EMRP executes regional software downloads from the MSC.3.2.1.5 EMRP with Speech Bus Access (EMRPS)The EMRPS is an EMRP with extended processor power and a speech businterface. The EMRPS implements the logical parts of the radio channelfunctions for the RBS 884 Pico (1900 MHz). The EMRPS executes softwaredownloads from the MSC.The EMRPS unit communicates with the MSC through the EMRPBinterface. Communication with the Radio Heads is through the RITSWand ELI units by way of the DEVSB interface in the CRI backplane. TheEMRPS unit is equipped with an onboard DC/DC converter that derives therequired internal voltages from the CRI backplane.2-18 1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05
System Description3.2.1.6 Enhanced Link Interface (ELI)The ELI is used to provide a T1/E1 connection between the CRI and theRadio Head. The device supports a single, 100-ohm twisted-pair 1.544Mbit/s long-haul or short-haul T1 interface, or a single, 120-ohm twistedpair or 75-ohm coaxial 2.048 Mbit/s long-haul or short-haul E1 interface.The ELI unit contains switches to select the link type (T1/E1 leased ornon-leased), short-haul T1 line build-up, long-haul attenuation and the75-ohm coaxial E1 cable grounding.The ELI maps the DEVSB time slots from the RITSW to the T1/E1 timeslots using a predefined multiplexing and mapping scheme. The ELI alsohandles the LAPD-based retransmission protocol at the CRI end of theconnection. On the Radio Head end, the RHI unit handles all time slotmapping and retransmission functionalityThe T1 interface utilizes Extended Superframe (ESF) framing format andBipolar with 8 Zero Substitution (B8ZS) line code. The E1 interface utilizesFrame Alignment Signal-Cyclic Redundancy Check (FAS-CRC) framingformat and High Density Bipolar Level 3 (HDB3) line code.A Light Emitting Diode (LED) lamp on the ELI indicates the status of theT1/E1 line. The ELI transmits the T1/E1 alarms back to the Radio Headcorresponding to the quality of the signal received on the T1/E1 line from theRadio Head. The ELI can be monitored and controlled by the EMRP throughthe backplane DEVCB with Digital Path (DIP) supervision.See Figure 2-8 on page 2-19 for an illustration of ELI unit and RadioHead connections.MSC Radio Head 1 Radio Head 2 Radio Head 3ELICRI T1/E1 T1/E1Long Haul T1/E1Long HaulT1/E1Leased LineLeased Linec c ccChannel Service UnitCRI Control and Radio InterfaceMSC Mobile Switching CenterFigure 2-8.

System Description3.2.1.7 Radio Interface Time Switch (RITSW)The RITSW is a local space/time switch in the CRI that routes DS0 timeslots between ETB, EMRPS and ELI. The RITSW also provides the clocksynchronization and stabilization in the CRI.The RITSW is controlled by the EMRP through the backplane DEVCB.The DEVCB interface to RITSW is used to set the semi-permanent DS0time-slot connections.3.2.1.8 Fan UnitThe Fan Unit is a physically separate part of the CRI subrack and is mounteddirectly above the subrack. The Fan Unit contains two fans that are poweredby the DC/DC converters in the subrack. The fans are rated such that a singlefan can provide sufficient cooling of the CRI.3.2.1.9 Cabinet Identification (CID) UnitThe CID Unit is located on the top-left side of the CRI floor mount versionand on the bottom-left side of the CRI rack mount version. The CID Unitallows a unique identification number to be set for the CRI cabinet duringinstallation. This number is read at the MSC to identify the cabinet foralarm reporting and fault resolution.3.2.1.10 Internal Alarm DistributionThe CRI distributes and reports the following equipment related alarms:•Fan alarm•DC/DC converter alarmThe alarms are distributed in the CRI as shown in Figure 2-9 on page 2-21.2-20 1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05

RBS 884 Pico (1900 MHz) CRI Installation1 IntroductionThis document contains step-by-step procedures for installing and cablingthe Control and Radio Interface (CRI) for the RBS 884 Pico (1900 MHz)System. Additional information is also provided for adding RBS 884 Picofunctionality to an existing RBS 884 Macro (1900 MHz) CRI unit.Note: The Radio Head installation procedures for the RBS 884 Pico(1900 MHz) are described in Part 4, RBS 884 Pico (1900 MHz)Radio Head Installation.2 Safety PrecautionsBefore starting any installation, test, or maintenance procedures, review thesafety regulations provided in this section and any other applicable partsof this manual. Additionally, the installer is responsible for determiningthat the installation conforms to all applicable electrical, mechanical,communications, and construction codes.Carefully review each procedure before starting, including theadmonishments (dangers, warnings, and cautions) that are applicable tothe procedure.2.1 Voltage HazardsDANGER!Hazardous voltages over 100V are used in the operation of this equipment.Use extreme caution when working on energized equipment. Contact withAC power of any voltage can cause injury and sometimes death.Always observe the following:•Shut off the power supply, if possible, before working on theequipment.•Remove all jewelry before working on the equipment.1/1531-AE/LZB 119 3834 Uae Rev PA6 2001-04-04 3-3
RBS 884 Pico (1900 MHz) CRI Installation•Do not touch high voltage connections when installing or operatingthe equipment.•If possible, keep one hand away from the equipment to reduce thepossibility of current flowing through vital body organs.2.2 Radio Frequency RadiationWarning!Radio frequency from an antenna may be a danger to health, causing severeburns to skin and clothing.Notify the MSC to switch off the transmitters if you work with or nearantennas.2.3 Beryllium OxideSome equipment contains beryllium oxide in ceramic form.Warning!Beryllium oxide is poisonous and constitutes a health hazard if present infinely dispersed form, such as dust or smoke, which can be inhaled. Readlocal hazardous chemical regulations before working with beryllium oxide.Units with components containing beryllium oxide are marked with awarning label. For detailed information about properties, health andenvironmental hazards, refer to the regulations issued by the local authorities.The following rules must be obeyed by all persons handling beryllium oxide:•Ceramics containing beryllium oxide must not be scraped, filed,ground, treated with acid, or machined in any other way.•Compressed air must not be used to clean units containing berylliumoxide.•Always wear protective gloves when handling beryllium oxide.•Use wet rags to collect dust and particles from damaged berylliumoxide components. After use, place the rags in plastic bags andseal the bags completely.3-4 1/1531-AE/LZB 119 3834 Uae Rev PA6 2001-04-04
RBS 884 Pico (1900 MHz) CRI InstallationScrapped beryllium oxide must be treated as environmentally hazardouswaste. Local authorities enforce regulations regarding the treatment anddisposal of environmentally hazardous waste. Investigate the applicablelocal regulations and comply with them.2.4 Heavy LoadsWarning!A heavy load (anything over 10 kg (22 lb) lifted incorrectly can cause injuryto persons and damage to the equipment. A factory-shipped RBS 884 PicoCRI cabinet weighs approximately 30 kg (66 lb).3 Electrostatic DischargeThe human body acquires static charge in all situations involving movement.The same effect is achieved when handling ordinary plastic materials.If the body comes into contact with a grounded Integrated Circuit (IC)component, this static charge may cause an Electrostatic Discharge (ESD)resulting in a spark and damage to the component.Note: To avoid component damage because of ESD, always followthe instructions for handling sensitive electronic componentsand circuit boards. Personnel must always use ESD protectionequipment when working with such components and circuitboards.3.1 Storage and TransportStore and transport components and hardware units in their originalpackaging.Alternatively, use a conductive material or special IC carrier that eithershort-circuits all contacts and pins or insulates them from external contact.1/1531-AE/LZB 119 3834 Uae Rev PA6 2001-04-04 3-5
