The RTTE directive covers essential requirements in the field of:protection of the Health and Safety of the user and any other person, including theobjectives with respect to safety requirements contained in the Low Voltagedirective (73/23/EEC).the protection requirements with respect to EMC contained in Directive89/336/EEC.The equipment generates, uses, and can radiate radio frequency energy. If notinstalled and used in accordance with the instruction manual, the equipment maycause harmful interference to radio communications. However, there is noguarantee that interference will not occur in a particular installation. If thisequipment does cause harmful interference to radio or television reception,which can be determined by turning the equipment off and on, the user isencouraged to try to correct the interference.The EMC requirements have been selected to ensure an adequate level ofcompatibility for apparatus at residential, commercial, and light industrialenvironments. The levels however, do not cover extreme cases which may occurin any location but with a low probability of occurrence. In particular, it may notcover those cases where a potential source of interference which is producingindividually repeated transient phenomena, or continuous phenomena, ispermanently present, for example a radar or broadcast site in the near vicinity. Insuch a case it may be necessary to either limit the source of interference, or usespecial protection applied, to the interfered part, or both.Note: For operation or maintenance inside Nortel Networks systems, theantistatic wrist shall always be used to maintain the integrity of theproduct.

BTS18000 overviewFront page of manual Welcome screenUser’s help screenNortel Networks Confidential 1--1BTS18000 Reference ManualCopyright E2002--2004 Nortel Networks1 BTS18000 OVERVIEW1.1 Key market trends1.1.1 Operating expenses savingsMost of the operators in Europe and Asia are going to install UMTS equipment ontheir networks, including UMTS radio cabinets. In most of the cases, these radioequipments will be co--located with existing GSM sites.Moreover, as GSM capacity increases in urban areas (voice and data traffic),operators will need to install new radio transmitters and will be forced to limit thenumber of additional radio cabinets required to carry the increasing traffic, in orderto contain the ”floor investments” at an acceptable level.This results in a need for a Base Transceiver Station (BTS) solution with a highnumber of transceivers per square meter, thus a cabinet which can house more TRXsin the same footprint than S8000 and S12000 cabinets. This results as well in theneed for reduced power consumption, operational effectiveness, antenna towerloading.1.1.2 Advent of new technologiesThe existing GSM European operators are almost all planning the deployment ofa 3G networks based on UMTS technology. Some of them have even started in 2001but the massive deployment is just about to start.In Asia, the scenario is almost the same and the Asian operators are also preparingfor 3G (CDMA 2000 or UMTS).In the Americas, the path to 3G for GSM operators is likely to stop off atGPRS/EDGE in a first stage with limited infrastructure investment before investingmassively in 3G technology.The challenge for these operators is to increase the capacity and complete thecoverage of their GSM network while they are starting their investments in 3Ginfrastructure. This results into two major difficulties for the operators:Radio sites congestion.Most of the urban sites are highly constrained by BTS footprint and will hardlyaccommodate for both 3G and increased capacity GSM/GPRS base stations.Therefore, dense and compact GSM and UMTS product solutions are required toanswer to this constraint.

GSM radio sites will bereused. Some solutions, as dual mode UMTS/GSM base stations and/orinfrastructure sharing between 3G operators, will allow cost--effectivelylaunching UMTS services, before smoothly migrating the subscriber base fromGSM to UMTS.This results in a need for a BTS solution supporting both GSM and UMTS.1.1.3 Investment protectionMost of the GSM operators are facing the challenges to increase the capacity andcoverage of their existing networks as traffic is growing, and in the same time startto invest in new UMTS network elements and buy expensive licenses. As aconsequence, the protection of the operators’ existing investments while they investin new network components is becoming more and more important to preserve theirbusiness profitability.This results in a need for a BTS solution which should offer the maximum ofcompatibility with the existing S8000 and S12000 BTSs installed on the field (e.g.possibility to expand existing sites).1.1.4 Network coverageGSM coverage is not everywhere today and the GSM operators will complete thecoverage of their network in the coming years, mainly in not very dense and ruralareas.This results in the need for a very cost--effective, low capacity solution, offeringhigh coverage capabilities in order to limit the investment and balance the businesscase of the operator for the low revenue generating areas.

This represents further integration of thesuccessful single module DRX approach for the receiver, transmitter and frameprocessor, used in Nortel Networks legacy S8000 and S12000 BTSs.The BTS18000 is an ideal site solution for operators:that have well established GSM networks evolving to EDGE, with a need forhigh density BTS in urban deployments,that are planning new hybrid GSM/UMTS networks enabling more advanceddata services traffic.These hybrid networks offer the ultimate balance of GSM and UMTS withoutany compromises. The inherent flexibility of the new BTS is the catalyst toaccelerate today’s investment decision needed to secure the operator’s successtoday and tomorrow.

Themaximum one--cabinet configuration is GSM S333 + UMTS STSR--2.This configuration can support up to two additional GSM extension cabinets of 18TRX. The maximum three--cabinet configuration is GSM S15.15.15 + UMTSSTSR--2.2.2 GSM featuresThe BTS18000 offers a set of features enhancing the Quality of Service and thespectrum efficiency of the network such as:Full support of GPRS data services.Full support of EDGE 8PSK modulation.Guaranteed --110 dBm dynamic single--branch receive sensitivity (GMSKmodulation) at the BTS antenna, without any tower--mounted Low NoiseAmplifier (LNA).Improved receiver diversity gain using a Nortel Networks specific algorithm,providing 5 dB or more diversity gain in most situations, when spatial diversityand de--correlated antennas are used.High output power with a 30W or 45W standard Power Amplifier (PA), and anoptional 60W High Power Amplifier.The BTS18000 cabinet can also be used as a very high density BTS inconjunction with an optional cabinet housing Multi Carrier Power Amplifiers(MCPA) and TX/RX antenna combiners.The MCPA feature allows high radio capacities using fewer RF feeders(8--Carriers per feeder at 43 dBm) and antennas:xwithout the coverage penalties of hybrid combiner solutions,xwithout the frequency hopping limitations of cavity combiner solutions.The MCPA feature leads to a S16.16.16 configuration in two BTS cabinets andone MCPA cabinet. The BTS18000 cabinet then contains up to 27 TRX withoutpower amplification. This BTS configuration is ideal for urban deployment withsevere space limitations and high capacity demands without compromising radiocoverage.

The DDM is aimedat providing:TX filtering (noise suppression),RX filtering (noise suppression),TX to RX isolation,front end low noise amplification for the receive chain.Front panelFigure 3--10 DDM front panel (with H2 coupling option)

It allows direct connection from theRM PA output to the antenna.The TXF only filters the signal transmitted from the PA to the antenna and does notprovide the reception path.Front panelFigure 3--12 TXF front panel (with H2 coupling option)TXF LEDs behaviorTwo LEDs are located on the TXF font panel in order to monitor TXF alarm:one LED is dedicated to DC power status,one LED is dedicated to VSWR meter.Table 3--19 describes the TXF LEDs behavior.LED Name Color MeaningPower FON when TX filter is powered onVSWRFFRed: VSWR alarm level 3Amber: VSWR alarm level 2OFF: no alarm or level 1Table 3--19 TXF LEDs behavior
