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 in descending order of severity of injury or damage and likelihood of occurrence. Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, 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 personal injury, 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 minor personal injury or property damage if the hazard is not avoided. GENERAL SAFETY PRECAUTIONS Warning: Wet conditions increase the potential for receiving an electrical shock when installing or using electrically-powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm. Page v © 2008, ADC Telecommunications, Inc. ADCP-75-348 • Issue 1 • 04/2008 • Preface Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transceiver of any digital unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transceiver or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles 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. Wherever possible, shut down the RAN before servicing the antenna. Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtails without severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bent or curved to a radius of less than 2 inches (5.1 cm). Caution: Exterior surfaces of the RU may be hot. Use caution during servicing. STANDARDS CERTIFICATION FCC: This equipment complies with the applicable sections of Title 47 CFR Part 15 (Host unit), Part 22 (800 MHz Cellular), Part 24 (1900 MHz - PCS), and Part 90 (800/900 - SMR). IC: This equipment complies with the applicable sections of RSS-131. The term “IC:” before the radio certification number only signifies that Industry Canada Technical Specifications were met. The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users.

ADCP-75-348 • Issue 1 • 04/2008 GENERAL The FlexWave URH product family of products is intended as a “next generation” distributed antenna system (DAS). DAS products provide bidirectional transport of digitized RF spectrum. Each link consists of a host unit (providing the interface between the base station RF ports and the optical fiber) and at least one remote unit (providing the interface between the optical fiber and the remote antenna). The difference in this product is the high-speed digitalization of a wideband portion of spectrum, that allows for transport of RF signals over extended distances, without the RF degradation that normally results when analog systems are impacted by optical effects. The basic function of the FlexWave URH platform is to transport via fiber optic cable RF signals form a Base Transceiver Station (BTS) to an antenna interface allowing communication to a mobile device. Multiple BTS communication paths are allowed over a single URH system. Diversity receive is supported. A block diagram of the system is shown in Figure 1.

FlexWave URH Block Diagram The basic function of the FlexWave URH simulcast (point-to-point) platform is to transport, via fiber optic cable, RF signals form a Base Transceiver Station (BTS) to multiple antenna interfaces allowing communication to a mobile device. Up to 8 simulcast remotes are supported. Page 1 © 2008, ADC Telecommunications, Inc. ADCP-75-348 • Issue 1 • 04/2008 INTRODUCTION The front access URH Host Unit interfaces with the BTS and performs the analog to digital and electrical to optical conversions for transport to the URH Remote Units. A typical URH system consists of a Host Unit (HU) and a Remote Unit (RU). The HU is designed for maximum RF flexibility to address Carriers changing and evolving spectrum needs, making the most use of cost efficient resources for serving multiple remotes such as simulcast architecture and sharing of common functions such as power, control and management over multiple host units. These features are designed into a compact package that reduces the amount of overall rack space required within a BTS Hotel. Each host chassis can support up to eight RUs. The HU is a three rack-unit high single-unit assembly that mounts in a standard equipment rack. The RU consists of an outdoor enclosure that houses various electronic components. The RU is a modular self-contained enclosure. Together the HU and the RU together comprise an URH system. Various accessory items are also available for use with each system. All items referenced as “accessory items” are not furnished and must be purchased separately. HOST UNIT DESCRIPTION A front view of the HU, shown in Figure 2, consists of an electronic circuit board assembly and a fan assembly that are mounted within a powder-paint coated sheet metal enclosure. The enclosure provides a mounting point for the circuit board and fan assembly and controls RF emissions. Fan assembly can be replaced in the field. Host Unit may be upgraded once it is installed to support additional URH Remote Units. This can be performed without disrupting service.

ADCP-75-348 • Issue 1 • 04/2008 3.1 Mounting The HU is intended for rack-mount applications. A pair of reversible mounting brackets is provided that allow the HU to be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. When installed, the front panel of the HU is flush with the front of the rack. Screws are provided for securing the HU to the equipment rack. 3.2 SeRF Card 3.2.1 Network Interface Connection SeRF front panel has an Ethernet port allowing interface communication with the internal processor and transfer of data to the optical protocol allowing IP transport between the HU and the remote(s). The network interface allows the HU to be controlled through a network. Network interface connection between the HU and the network is supported by a RJ-45 jack 10/ 100Base-T (IEEE802.3 compliant) with integrated green ACTIVITY and LINK LEDs. The Ethernet port supports a maximum cable length of 100 meters (328 feet) to a hub or back-toback nodes. CAT5 or better cable should be used when making this connection. The Ethernet connection should not be connected to an Ethernet circuit used outside the building. 1. The IEEE Specification for Ethernet 100BaseT requires that two twisted pairs be used and that one pair is connected to pins 1 and 2, and that the second pair is connected to pins 3 and 6. 2. Pinout information is shown in Table 1. See Figure 3 for RJ45 connector wiring information.

One connector is used for the forward path RF signal. The other connector is used for the reverse path RF signal. In some installations, it may be necessary to install a Conditioning Panel and/or Duplexing Panel (accessory items) to support the interface between the HU and the BTS. The HU should be as close as possible to the BTS to minimize cable losses. 3.4 System Card The System Interface Card gives additional front panel space for the SeRF card. The System Card front panel also provides connections for alarm outputs, 10 MHz output, and status LEDs. This card may be used to provide a 10 MHz clock reference to which the SeRF's Master clock is frequency locked from the internal crystal oscillator. When the internal clock is not used the clock can be obtained from an external 10 MHz input. 3.5 Power Supply HU is powered by a modular DC to DC power supply located on the lower left side of the chassis. An On/Off switch is provided on the HU power supply module front panel. HU is powered by ± 20 to ± 60 VDC power (nominal ± 24 or ± 48 VDC), power is fed to the HU through a connector located on the front of the module. Power to the HU must be supplied through a fuse panel (available separately). Each HU must be protected with a fuse. 3.6 User Interface The HU user interface consists of the various connectors, switches, terminals, and LEDs that are provided on the HU front panel.

ADCP-75-348 • Issue 1 • 04/2008 6.3 OSP Fiber Cable Installation Guidelines The outside plant (OSP) fiber optic cables should be routed between the HU distribution panel and RU outside plant cabinet and terminated before the equipment is installed. A diagram of a typical OSP cable routing is shown in Figure 7. At the HU, the OSP cable should be terminated at a fiber distribution panel and spliced to pigtails. Jumper patch cords may then be used to link the HU optical ports to the OSP cable terminations. Whenever possible, a guideway such as the FiberGuide system should be provided to protect the fiber optic patch cords from damage and to prevent excessive bending. The procedures for connecting the OSP cable optical fibers to the HU is provided in Section 6.8.

Secure each host module to the mounting shelf by twisting the handle on each quarter-turn fastener 90º. 7. Carefully store the pigtail leads from each host module. The routing and connection procedures for the pigtails are provided in Section 6.8. 6.5 HU Mounting Procedure The HU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Both US standard and metric machine screws are included for rack mounting the HU. When loading the HU in a rack, make sure the mechanical loading of the rack is even to avoid a hazardous condition such as a severely unbalanced rack. The rack should safely support the combined weight of all the equipment it holds. In addition, maximum recommended ambient temperature for the HU is 55º C (131º F). Allow sufficient air circulation or space between units when the HU is installed in a multi-rack assembly because the operating ambient temperature of the rack environment might be greater than room ambient. Page 13 © 2008, ADC Telecommunications, Inc. ADCP-75-348 • Issue 1 • 04/2008 Warning: Wet conditions increase the potential for receiving an electrical shock when installing or using electrically powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm. Note: To insure that all optical connectors remain dust-free during installation, leave all dust caps and dust protectors in place until directed to remove them for connection. Use the following procedure to install the HU in the equipment rack: 1. The HU is shipped with the mounting brackets installed for 19-inch rack installations. If mounting the HU in a 19-inch rack, proceed to Step 4. If mounting the HU in a 23-inch rack, proceed to Step 2. 2. Remove both mounting brackets from the HU (requires TORX screwdriver with T20 bit) and save screws (six-screws on each side) for reuse. 3. Reinstall both mounting brackets so the short side of the bracket is flush with the HU front panel as shown in Figure 10. Use the screws removed in Step 2 to re-attach the brackets to the HU chassis. INSTALL MOUNTING BRACKETS AS SHOWN FOR INSTALLATION IN 23-INCH RACKS 22394-A Figure 10. Installing the Mounting Brackets for 23-Inch Rack Installations 4. Position the HU in the designated mounting space in the rack (per system design plan) and then secure (but do not tighten) the HU to the rack using the four machine screws provided (use #12-24 or M6 x 10 screws, whichever is appropriate). Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and right sides of the HU for air intake and exhaust. 5. Locate two vertical cable guides, not provided with the HU.

Pay particular attention to ground source connections. Page 15 © 2008, ADC Telecommunications, Inc. ADCP-75-348 • Issue 1 • 04/2008 6.7 Coaxial Cable Connections The RF interface between the HU DART card and the EBTS/BTS is supported through two type QMA female connectors mounted on each DART front panel. One connector provides the coaxial cable connection for the forward path (downlink) signal and the other connector provides the coaxial cable connection for the reverse path (uplink) signal. In most installations, it is usually necessary to insert an external attenuator into the forward path link between the HU and the BTS. A signal level that is greater than –9 dBm will overdrive and possibly damage the HU receiver. Before completing the forward path connection at the BTS, verify that the composite forward path RF signal level at the HU is between –25 and +5 dBm. The HU should be mounted as close as possible to the EBTS/BTS to minimize cable losses. Use the following procedure to route and connect the forward and reverse path coaxial cables to the HU DART cards: 1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial communications cable (RG-400 or equivalent) for all coaxial connections. 2. Route the forward and reverse path coaxial cables between the HU and the BTS interface (per system design plan) and cut to the required length. Allow sufficient slack for dressing and organizing cables at the HU and for installing an external attenuator in the forward path link. 3. Terminate each cable with an QMA-Type male connector following the connector supplier’s recommendations. 4. If required, install an external attenuator in the forward path. Note: The composite forward path RF signal level at the HU must be between –25 and +5 dBm. Do not connect the forward path cable until the composite forward path RF signal level is measured and the amount of external attenuation required is determined. 5. Connect the forward path cable to the FWD RF IN connector on the HU DART front panel as shown in Figure 12. 6. Connect the reverse path cable to the REV RF OUT connector on the HU DART front panel (see Figure 12). 7. Repeat this procedure for the remaining DART cards in the HU. 8. Dress and secure cables at the right side of the HU. 9. Complete all remaining coaxial connections as specified in the system design plan. Page 16 © 2008, ADC Telecommunications, Inc. ADCP-75-348 • Issue 1 • 04/2008 22411-A Figure 12. Forward and Reverse Path Coaxial Cable Connections 6.8 Optical Connections The optical interface between the HU and the RU is supported by optical ports. Each optical port consists of an SFP with LC optical transceivers mounted on the SeRF card front panel. Each FWD port provides an optical connection for the forward path (downlink) signal. Each REV port provide an optical connection for the reverse path (uplink) signal. Each REV port can also provide the optical connection for the diversity reverse path (uplink) signal. The optical connections are dependent on whether or not a WDM host module (accessory) is installed: • If the installation does not include a WDM module, proceed to Section 6.8.1 for the optical connections procedure. • If the installation includes a WDM module, proceed to Section 6.8.2 for the optical connections procedure. Page 17 © 2008, ADC Telecommunications, Inc. ADCP-75-348 • Issue 1 • 04/2008 Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transmitter of any unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transmitter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the connector. 6.8.1 Optical Connections Without WDM System Use the following procedure to connect the optical fibers when there is no WDM installed with the HU: 1. Obtain two patch cords that are of sufficient length to reach from the HU to the fiber distribution panel. 2. Designate one of the patch cords as the forward path link and the other as the reverse path link and attach an identification label or tag next to the connector. 3. Remove the dust caps from the HU SeRF SFP optical ports and from the patch cord connectors that will be connected to the SeRF SFP optical ports. 4. Clean each patch cord connector following the patch cord supplier’s recommendations. Note: To protect the optical receivers, insert a 15 dB attenuator in each optical path. When the system is turned-up and tested, the attenuator may be resized or removed. 5. Insert each patch cord connector into the appropriate optical port as shown in Figure 13 and as specified by the following: PORT 1 FWD - Forward path patch cord PORT 1 REV - Reverse path patch cord Caution: Improper handling can damage fiber optic cables. Do not bend fiber optic cable more sharply than the minimum recommended bend radius specified by the cable manufacturer. Do not apply more pulling force to the cable than specified. 6. Route the patch cords from the HU to the fiber distribution panel. Note: The HU optical adapters are angled to the left. Therefore, always route patch cords to the HU from the left side of the rack. Routing patch cords to the HU from the right may exceed the bend radius limitations for the optical fiber. 7. At the fiber distribution panel, identify the OSP cable optical fiber terminations that correspond to the forward and reverse paths. 8. Remove the dust caps from the OSP cable optical fiber adapters and from the patch cord connectors. 9. Clean each patch cord connector (follow patch cord supplier’s recommendations) and then mate the connector with the appropriate OSP cable adapter. Page 18 © 2008, ADC Telecommunications, Inc.

Remove the dust cap from the OSP cable optical adapter and from the patch cord connector. 8. Clean the patch cord connector (follow patch cord supplier’s recommendations) and then mate the connector with the appropriate OSP cable adapter. 9. Store any excess patch cord slack at the fiber distribution panel. 10. Obtain two patch cords that are of sufficient length to reach from the WDM module to the HU. 11. Designate one of the patch cords as the forward path link and the other as the reverse path link and attach an identification label or tag next to the connector. 12. Remove the dust caps from the HU SeRF SFP optical ports and from the patch cord connectors that will be connected to the SeRF SFP optical ports. 13. Clean each pigtail connector (follow the procedures provided with the WDM module) and then insert the connector into the appropriate optical port on the HU as shown in Figure 13 and as diagramed in Figure 14. Note: To protect the optical receivers, insert a 15 dB attenuator in each optical path. When the system is turned-up and tested, the attenuator may be resized or removed. Page 20 © 2008, ADC Telecommunications, Inc. ADCP-75-348 • Issue 1 • 04/2008 Note: The HU SeRF SFP optical adapters are angled to the left. Therefore, pigtails should always be routed to the HU from the left side of the rack. Routing pigtails to the HU from the right side of the rack may exceed the bend radius limitations for the optical fiber. 6.9 EXT REF Connections Note: When using the 10 MHz external reference clock the signal must be connected to the HU before enabling the clock source in the software. EXT REF connections between multiple HU’s is supported through two QMA type female connectors mounted on the System card. One of the jacks is designated as the IN port and the other jack is designated as the OUT port. The EXT REF interface allows HU’s to be connected together (in daisy-chain fashion) and clocked through a single source. Use the following procedure to connect EXT REF interface cables between multiple HU’s: 1. Connect one end of the EXT REF interface cable (accessory) to either the IN or OUT port on HU #1 as shown in Figure 15. 22407-A Figure 15. EXT REF Connections 2. Route the EXT REF interface cable to HU #2 and connect the cable’s free end to the port that is the logical opposite of the EXT REF interface connection at HU #1.
