ADCP-75-210 • Issue 1 • November 2006 • PrefacePage viii© 2006, ADC Telecommunications, Inc.ADMONISHMENTSImportant safety admonishments are used throughout this manual to warn of possible hazards topersons or equipment. An admonishment identifies a possible hazard and then explains whatmay happen if the hazard is not avoided. The admonishments — in the form of Dangers,Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed indescending order of severity of injury or damage and likelihood of occurrence.GENERAL SAFETY PRECAUTIONS-Danger: Danger is used to indicate the presence of a hazard that will cause severe personalinjury, death, or substantial property damage if the hazard is not avoided.Warning: Warning is used to indicate the presence of a hazard that can cause severe personalinjury, death, or substantial property damage if the hazard is not avoided.Caution: Caution is used to indicate the presence of a hazard that will or can cause minorpersonal injury or property damage if the hazard is not avoided.Warning: Wet conditions increase the potential for receiving an electrical shock wheninstalling or using electrically-powered equipment. To prevent electrical shock, never install oruse electrical equipment in a wet location or during a lightning storm. Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiationcan seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do notlook directly into the optical transceiver of any digital unit or exposure to laser radiation mayresult. An optical power meter should be used to verify active fibers. A protective cap or hoodMUST be immediately placed over any radiating transceiver or optical fiber connector to avoidthe potential of dangerous amounts of radiation exposure. This practice also prevents dirtparticles from entering the adapter or connector.Caution: This system is a RF Transmitter and continuously emits RF energy. Maintain 3 foot(91.4 cm) minimum clearance from the antenna while the system is operating. Whereverpossible, shut down the RAN before servicing the antenna.Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtailswithout severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bentor curved to a radius of less than 2 inches (5.1 cm). Caution: Exterior surfaces of the RAN may be hot. Use caution during servicing.
ADCP-75-210 • Issue 1 • November 2006 • PrefacePage ix© 2006, ADC Telecommunications, Inc.SAFE WORKING DISTANCESThe Digivance NXD antenna, which is mounted on top of a pole, radiates radio frequencyenergy.For the occupational worker, safe working distance from the antenna depends on the workerslocation with respect to the antenna and the number of wireless service providers being servicedby that antenna.Emission limits are from OET Bulletin 65 Edition 97-01, Table 1 A. STANDARDS CERTIFICATIONFCC: The Digivance NXD complies with the applicable sections of Title 47 CFR Part 15, 22,24 and 90.The Digivance NXD Hub has been tested and found to comply with the limits for a Class A dig-ital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonableprotection against harmful interference when the equipment is operated in a commercial envi-ronment. This equipment generates, uses, and can radiate radio frequency energy and, if notinstalled and used in accordance with the instruction manual, may cause harmful interference toradio communications. Changes and modifications not expressly approved by the manufacturer or registrant of thisequipment can void your authority to operate this equipment under Federal CommunicationsCommissions rules.In order to maintain compliance with FCC regulations, shielded cables must be used with thisequipment. Operation with non-approved equipment or unshielded cables is likely to result ininterference to radio & television reception.ETL: This equipment complies with ANSI/UL 60950-1 Information Technology Equipment.This equipment provides the degree of protection specified by IP24 as defined in IECPublication 529. Ethernet signals are not for outside plant use.FDA/CDRH: This equipment uses a Class 1 LASER according to FDA/CDRH Rules. Thisproduct conforms to all applicable standards of 21 CFR Part 1040.IC: This equipment complies with the applicable sections of RSS-131.

ADCP-75-210 • Issue 1 • November 2006Page 1© 2006, ADC Telecommunications, Inc.1 PRODUCT DESCRIPTIONThis section describes the Digivance Neutral Host (NXD) Radio Access Node (RAN).1.1 General DescriptionThe RAN, shown in Figure 1, is the remote component in the Digivance NXD Multi-BandDistributed Antenna System. The RAN is a pole-mounted or pad-mounted, weather-resistentcabinet, housing electronic modules that operate on an internal cPCI backplane. Included are acentral processing unit, a system interface, an optical interface, optical to RF data converters,RF multicouplers, and DC power supplies. The RAN also houses rectifiers, backup batteries,power amplifiers, and optical wave division multiplexers. Optical and RF functions are bothrequired because the RAN exchanges data with the system Hub using an optical link andexchanges data with wireless users using RF signals. Each RAN provides the system with an RFantenna and can accommodate up to four bands (PCS A-F, SMR A, Cell A”/A, or Cell B/B’). DualRANs installed at the same location can accommodate up to eight bands using a commonantenna. Figure 1. NXD RAN21227-A
ADCP-75-210 • Issue 1 • November 2006Page 2© 2006, ADC Telecommunications, Inc.1.2 System FunctionThe NXD Distributed Antenna System (DAS), in which the RAN is the remote component, is amulti-frequency, multi-protocol RF access network providing microcellular Cellular and PCScoverage via a distributed RF access system. In a typical configuration, such as shown inFigure 2, multiple RANs are connected to a central Hub where multiple Base TransceiverStation (BTS) interfaces are located. Signals received at the Hub are distributed to the RANs indigital form by way of a fiber optical link. Within the RANs, the signals are converted fromdigital to RF format to be transmitted from the RAN antennas. Signals also travel in a reversedirection, from the RANs to the Hub, with a reverse data conversion.Physically, the DAS consists primarily of electronic modules located in the Hub and RANs. Atthe Hub, these modules are mounted in an equipment rack typically housed in a commontelecommunications structure with the base station electronics for Wireless Service Providers(WSPs), either in the same room or nearby. These modules include high power attenuators, basestation modules, a power distribution unit, an Ethernet hub, a Hub reference module, an RFchassis, and one or more digital chassis. The RAN electronic modules, mounted in the RANcabinet, perform the remote system functions of optical to RF data conversion and RF access.These modules are described in subsequent topics within this product description. DigivanceElement Management System (EMS) software, running on a computer located at the Hub,provides a graphical user interface to monitor system performance. Figure 2.

Thesecomponents include:•RAN Cabinet: exterior shell of the RAN containing cable connection points, groundstuds, and slots or shelves supporting other RAN components.•RAN Chassis: standard Compact PCI (cPCI) shelf capable of housing 21 industrystandard cPCI circuit card modules. The modules are plugged into a common backplaneproviding data bussing between them.•Related Electronics: including rectifiers, Power Amplifier Assemblies (PAAs), batteries,multiplexers, and a circuit breaker panel. All components called out in the figure except for the multiplexers are separately installable inthe field. In most cases, however, the RAN is shipped with a basic set of components havingbeen ordered in advance by the customer and installed in the factory.Figure 3.

The cabinet is weather-tight but contact with salt-air mist shouldbe avoided as it may decrease the mean time between failure of some components. The cabinethas ventilation openings to allow entry of cool air and escape of hot air. The cabinet providestermination points for the coaxial antenna cable, fiber optic cable, ground cable, and AC cable.The cabinet has inbuilt AC power surge protection and limited storage for fiber optic cables.1.6.1 MountingThe RAN cabinet may be mounted on a wood pole or on a concrete pad. Mounting bracket kits(available from ADC) are required for each type of installation.
