4-3System RequirementsAn LGCell system has location, space, power, and safety requirements for installation. The Dual Band LGCell requirements for space and power are different from those for a single-band system and are noted below.System LocationThe LGCell Main Hub and Expansion Hub mount into a standard 19" equipment rack in a wiring, telecom, or electrical closet, which may contain other Ethernet, telephony, or miscellaneous equipment.•Standard wiring closet temperatures: 0-45° C•Does not require special air conditioningSpace RequirementsThe LGCell Main Hub and Expansion Hubs are installed into a standard 19” rack.•The Main Hub height is 1.7” (44.5 mm). The Dual Band Main Hub is 3.5” (88.9 mm) high.•The Expansion Hub height is 1.7” (44.5 mm). The Dual Band Expansion Hub is 3.5” (88.9 mm) high.•Allow at least one inch (25 mm) clearance between each hub, between any existing equipment in the rack, and between the bottom shelf of the rack and the hub.Power RequirementsThe LGCell requires AC voltage/current. LGC Wireless recommends connecting it to a UPS (Uninterruptable Power Supply), which may exist in the wiring closet. Dual-Band equipment requires twice as much power as single-band equipment.•LGCell operates with 88-264 VAC 50/60 Hz.•The Main Hub uses a maximum of 1.6 A of electrical current.•The Expansion Hub uses a maximum of 1.6 A of electrical current.•The RAUs are powered from the Expansion Hubs via the UTP/STP cable and they use 12V DC.

4-4 LGCell InstallationUnderwriters Laboratory Installation GuidelinesUse the following guidelines when rack mounting the LGC Cell:1Do not exceed the maximum ambient air temperature of 45° C during operation. Provide sufficient airflow and cooling within the rack to prevent heat build-up from exceeding this limit.2Be careful when servicing these products. If you are removing the system from the rack, turn it off and remove the power cord first. There are no user serviceable parts inside the hubs or RAUs.3Do not compromise the amount of airflow required for safe operation of the equipment when installing it in a rack. Both the Main Hub and the Expansion Hub draw in air on the left side and exhaust heated air at the rear. The hubs pass approximately 6 cu. ft. of air per minute through themselves and only dissipate a maximum of 25 watts of heat from their internal circuitry.4The AC input current consumption of the hubs is rated at 1.6 A at 110 VAC. The internal power supply has internal fuses that are not user replaceable. Consider the worst-case power consumption shown on the product labels when provisioning the rack’s AC power source and distribution.Fiber Port Safety PrecautionsSuggested safety precautions for working with LGCell Fiber Ports follow. For information about LGCell compliance with safety standards, see Appendix C – Compliance Information.•Viewing fiber: Observe the following warning about viewing fiber ends and ports.Do not stare with unprotected eyes at the connector ends of the fibers or the ports of the hubs. Invisible infrared radiation is present at the front panel of the Main Hub and Expansion Hub. Do not remove the Fiber Port dust cover unless the port is in use. Do not stare directly into a Fiber Port.•Test fiber cables: When you use test fiber optical cables, connect the optical power source last and disconnect it first.•Fiber ends: Cover any unconnected fiber ends with an approved cap. Do not use tape.•Broken fiber cables: Do not stare with unprotected eyes at any broken ends of the fibers. Report any broken fiber cables and have them replaced.•Cleaning: Use only approved methods for cleaning optical fiber connectors.•Modifications: Do not make any unauthorized modifications to this fiber optical system or associated equipment.

4-5•Live work: Live work is permitted on the LGCell as it is a Class 1 hazard.•Signs: No warning signs are required.•Test equipment: Use Class 1 test equipment.Cable and Connector RequirementsThe LGCell equipment operates over standard TIA/EIA 568-A specification, Category 5 (CAT 5), or better, Unshielded Twisted Pair (UTP) or Shielded Twisted Pair (STP) and standard 62.5µm/125µm Multi-Mode Fiber cable (MMF), at a wavelength of 1300 nanometers (nm). These cables are widely used industry standards for Local Area Networks (LANs). The regulations, guidelines, and standards for cable installation are identical to those specified by the TIA/EIA 568-A standard for LANs. See Appendix B – TIA/EIA 568-A Cabling Standard.LGC Wireless recommends Plenum rated CAT 5 UTP/STP and MMF cable and connectors for conformity to building codes and standards.LGCell Standard Equipment•LGCell Main Hub•LGCell Expansion Hub•Remote Antenna Units (RAUs) with an in-building antenna•Four screws for mounting the RAUs•Four rack mount screws per hub to mount hubs into a 19" rack•Installation and Reference GuideLGCell Equipment InstallationThe following are procedures for installing an LGCell system. Pre-testing the system is not required. The installation procedures are based on the following assumptions:•The LGCell equipment has been unpacked and inspected.•Locations for the Main Hub, Expansion Hubs, and RAUs have been identified.•19" rack space is available in the wiring closets.•AC power is available for the LGCell.•MMF and UTP/STP have been pulled into place (based on previous design) and terminated.

4-8 LGCell Installation2 Connect Power and Power UpAfter mounting the Main Hub, connect the AC power cord to the Main Hub. Plug the power cord into an outlet providing AC power (88-264 VAC). See 1 in graphic.Power up the Main Hub by flipping the power switch from position 0 to position 1. See 2 in graphic.The POWER and SYNC LEDs on the front panel should be green (lit).3 Connect the MMF cablesUsing the procedure below, connect all MMF cables (two per port) to the MMF ST-female connectors (labeled DOWN and UP) on the Main Hub front panel. Use any available Main Hub port.

4-9Be sure the MMF cable ST-connectors are clean and free of dust or oils. If the fiber connector front face is not free of dust or oils, follow the manufacturer’s recommendations for cleaning it.The MMF cable is labeled with either 1 or 2, or is color-coded. This distinguishes the connectors for proper connection between the Main Hub and Expansion Hubs.If the fiber jumper is labeled with 1 or 2:•Connect 1 to UP on Main Hub•Connect 1 to UP on Expansion Hub•Connect 2 to DOWN on Main Hub•Connect 2 to DOWN on Expansion HubIf the fiber jumper is color-coded (for example, “blue” or “red”):•Connect “blue” to UP on Main Hub•Connect “blue” to UP on Expansion Hub•Connect “red” to DOWN on Main Hub•Connect “red” to DOWN on Expansion HubThe connections for the Dual Band system are shown here. Make sure you connect the 900 MHz Main Hub to the 900 MHz Expansion Hub and the 1800 MHz hubs together.

4-10 LGCell InstallationBe sure to record which number or color is connected to UP and to DOWN. This information is needed when connecting the other end of the MMF cables to the Expansion Hub ports.Expansion Hub InstallationThe Expansion Hubs may be located in the same or different wiring closets, and they may be located in a different wiring closet than the Main Hub. Use the following procedures for all Expansion Hubs.4 Check Main Hub LEDsThe POWER and SYNC LEDs should be green. If not, reset the Main Hub.If the POWER and SYNC LEDs do not light green, see Section 6, Common Problems, Troubleshooting, and Frequently Asked Questions.The LINK STATUS and SYNC LEDs on the ports where the fiber is connected should be red. This indicates that the other end of the MMF cable is not yet connected to the Expansion Hub ports.

4-111 Mount the Expansion HubsMount the Expansion Hubs onto the rack in the assigned wiring closet location, using four screws per hub.For air circulation, be sure to leave at least one inch (25 mm) space between all hubs and between any other equipment in the rack. If mounting a hub on the rack’s bottom shelf, also leave at least one inch (25 mm) clearance from the bottom.2 Connect Power and Power UpConnect the AC power cord to the Expansion Hub. Plug the power cord into an outlet providing AC power (88-264 VAC). See 1 in graphic.Power up the Expansion Hubs by flipping the power switch from position 0 to position 1. See 2 in graphic. The POWER LED on the Expansion hub should be green (lit).

4-15The Dual Band RAU mounting is shown below.3 Connect UTP/STP CableConnect the UTP/STP cable coming from the Expansion Hub to the RJ-45 connector on the RAU.

4-16 LGCell InstallationRF Cable ConnectionBefore connecting any cables to the Main Hub, be sure the RF power level does not exceed the input rating for the Main Hub. (See “LGCell System Specifications” on page 16 in Section 2, LGCell Equipment.)For coverage applications, LGC Wireless recommends that you insert a lightning arrestor or surge protector between a roof-mounted antenna and the Main Hub. If you use a repeater, insert the lightning arrestor or surge protector between the repeater and roof-mounted antenna.The following illustration shows how to connect the LGCell for coverage applications, with a repeater.For the Dual Band RAU, connect the 900 MHz Expansion Hub cable to the top connector and the 1800 MHz cable to the bottom connector.4 Check LEDsThe green POWER LED should be on and the red ALARM LED should be off.The green LED indicates that the RAU is receiving power from the Expansion Hub assigned to it.

4-17Duplex ConnectorThis N-type female connector is typically used to connect the LGCell to a repeater, roof-mounted antenna, or MBS, as shown on the previous page.Connect an N-type male RF coaxial cable to the duplex N-type female connector (labeled DUPLEX) on the Main Hub back panel. If an N-type male connectorized RF cable is not available, use an RF adaptor. Connect the other end of the coaxial cable to the roof-mounted antenna, MBS, or repeater.a0721234DOWNLINKSTATUSSYNCUPSYNCPOWERAC POWERTO EXPANSION HUB PORTSLGC WIRELESSLGCell™ Main HubDOWNLINKSTATUSSYNCUPDOWNLINKSTATUSSYNCUPDOWNLINKSTATUSSYNCUPUplink (Reverse) and Downlink (Forward) -MainHubN-Male to N-Male Coaxial CablesN-Male to N-Male Coaxial CablesRoof-Mounted AntennaSurge SuppressorRepeaterTo Ground ConnectorDuplexOutput

4-18 LGCell InstallationThe duplex ports have a variable gain. Please see the table for system gain under “Maximum Input RF Power per Carrier vs. Number of Carriers” on page 17 in Section 2, LGCell Equipment.Downlink (Forward) and Uplink (Reverse) ConnectorsConnect an N-type male RF coaxial cable to the downlink N-type female connector (labeled FORWARD) and an N-type male RF coaxial cable to the uplink N-type female connector (labeled REVERSE) on the Main Hub back panel.Connect the other ends of the coaxial cable to the MBS. For diagrams of connecting LGCell to specific MBS equipment, see Section 5, Connectivity.For simplex MBSs, be sure the MBS downlink coaxial cable connector plugs into the downlink connector, and the uplink coaxial cable connector plugs into the uplink connector on the Main Hub.Alarm Report MonitorA separately orderable option for use with LGCell, the Alarm Report Monitor is an alarm monitoring, reporting, and remote control system. Up to 255 remote-ARM monitoring units can monitor up to 2,040 LGCell systems. Each remote-ARM unit communicates with the ARM software through a dial-up modem connection, using an external or internal modem. A database of these devices is set up in a PC, with a unique address for each device.The ARM supports multiple users and tracks responsibility through log-in and log-out procedures, using four security levels to protect critical system functions. It features a graphic color status display, remote system reset control, alarm history and control logs, security code management, and journal printer and paging options.For ARM installation instructions, see Appendix E – Alarm Report Monitor (ARM2000).a060DUPLEXFORWARDREVERSE

5-3 Connecting Multiple LGCell SystemsConnecting multiple LGCell systems increases the total number of Remote Antenna Units (RAUs). Multiple LGCells can be stacked to increase the total number of RAUs through the use of power combiner/dividers.LGC Wireless provides Integration Modules which may be used with the LGCell to efficiently centralize additional radio capacity inside a facility. These Modules provide the connection between the radios for the facility and the LGCell system. Because the Integration Modules distribute all available radio capacity automatically among all antennas within a cell, available capacity is dynamically allocated throughout the entire coverage area, thus providing an improved grade of service without the need to conduct ongoing traffic monitoring and analysis. Specific installation information on all available Integration Modules may be found in the Integration Module Installation and Reference Manual.Connecting two LGCellsConnecting two LGCells increases the total number of RAUs from 16 to 32. A 2x1 or 2x2 hybrid power combiner/divider is required (see graphic below).a0091234DOWNLINKSTATUSSYNCUPSYNCPOWERAC POWERTO EXPANSION HUB PORTSLGC WIRELESSLGCell™ Main HubDOWNLINKSTATUSSYNCUPDOWNLINKSTATUSSYNCUPDOWNLINKSTATUSSYNCUP1234DOWNLINKSTATUSSYNCUPSYNCPOWERAC POWERTO EXPANSION HUB PORTSLGC WIRELESSLGCell™ Main HubDOWNLINKSTATUSSYNCUPDOWNLINKSTATUSSYNCUPDOWNLINKSTATUSSYNCUPMain Hubs2 x 1 Power CombinerN-Female ConnectorsIn Back of MHN-Male to N-MaleCoaxial Jumper Cables (2)N-Male to N-MaleCoaxial Jumper CablesN-Female Connectors (3)To Antenna on Roofor MBS or Repeater

5-4 ConnectivityThe following are procedures for connecting two LGCells. For Dual Band installations, connect a power combiner/divider for each Main Hub band.1 Connect Cables2 Check Main Hub LEDsAfter connecting the LGCells, check all Main Hub LEDs to ensure that the system is operating properly.Connecting More Than Two LGCellsRepeat this procedure to connect any number of LGCell systems. For three systems, use a 3x1 power combiner/divider, and so on.Connecting LGCell to Base Stations, Microcells, or PicocellsOne or more LGCell systems can connect with any base station, microcell, or picocell. Before connecting an LGCell system to one of these, confirm the following items:•Connector type (LGCell uses N-type connectors)•Power distribution (LGCell supports either duplex or simplex)•Maximum power output (dBm) (Do not exceed the maximum input power into the Main Hub. If the input power is too high, an attenuator might be required.)For more information about connections to microcellular base stations or picocells, including connections to multiple base stations, see the Integration Module Installation and Reference Manual.From LGCells to Hybrid Power Combiner/Divider To Roof-Mounted Antenna, Repeater, or MBSConnect the DUPLEX, FORWARD, or REVERSE connector of one of the Main Hubs to an input/output port on the power combiner/divider using an N-male to N-male coaxial cable jumper.Connect the combined port of the power combiner/divider to a roof-mounted antenna, repeater, or MBS using an N-male to N-male coaxial cable jumper.Connect the DUPLEX, FORWARD, or REVERSE connector of the second Main Hub to the second input/output port on the power combiner/divider using an N-male to N-male coaxial cable jumper.

6-2 Common Problems, Troubleshooting, and Frequently Asked Questions

6-3Common Problems and TroubleshootingThe LGCell has three sources of potential problems:•Malfunction of one or more LGCell component•Faulty cabling/connector•Antenna, base station, or repeater problemBy far, most problems discovered have to do with faulty cabling. All CAT 5 cable should be tested to TIA/EIA 568-A specifications.The diagnostic procedures are based on information in the Diagnostic Table on page 9. The table lists all LEDs and indicates what to do under certain circumstances. There is a blank table at the end of this section that you can copy and use to record the LEDs while you troubleshoot an LGCell system.After following the recommended procedures, if you cannot determine the cause of a problem, call LGC Wireless customer help hotline: 1-800-530-9960(International customers, please call +1-408-487-2400 for assistance.)

6-4 Common Problems, Troubleshooting, and Frequently Asked QuestionsLED Indicator DescriptionThe LGCell Main Hub, Expansion Hubs, and RAUs have front panel LEDs. The LEDs provide diagnostic information and operational status of each unit. Together they provide an efficient diagnostic display system, which help technicians find the fault if there is a malfunction.Main Hub LEDsThere are two sets of LEDs on the Main Hub front panel:•Main Hub MMF Ports •Main Hub Functionality LEDs•Main Hub MMF Ports LEDsProvides status on each of the Main Hub’s four MMF ports.•Main Hub Functionality LEDsThe LEDs provide diagnostic information on the Main Hub’s functionality.LED Color IndicationLINK STATUS GreenRedIndicates a good connection to Expansion Hub for that port.Connection problem to Expansion Hub.SYNC GreenRedIndicates Expansion Hub and any RAUs connected to it are operating properly.Problem with Expansion Hub or one of the RAUs.LED Color IndicationSYNC Green Indicates Main Hub is correctly producing the synchronization signal.POWER Green Turns green when Main Hub has power.

6-6 Common Problems, Troubleshooting, and Frequently Asked QuestionsRAU LEDsRAUs have two LEDs:•Sync•PowerTroubleshooting GuidelinesThe LGCell Main Hub, Expansion Hub, and RAUs have front-panel indicator LEDs that provide diagnostic information and the operational status of each unit. Together they provide an efficient diagnostic display system for maintenance and fault location if a malfunction ever exists. The troubleshooting procedures in this section are based on the front panel diagnostic LEDs.The following table contains supplementary troubleshooting information that the diagnostic LEDs do not cover. Please check the table for a possible cause of a problem. Some simple checks or a minor adjustment might eliminate the problem and restore proper operation.LED Color IndicationSYNC Red Antenna lost sync and has shut down RF power.POWER Green Antenna is plugged in and the connected Expansion Hub is on.

6-7Problem/Symptoms CheckNo downlink signal output when all diagnostic LEDs are green. Make sure that there is a reasonable amount of power at the input of the Main Hub. Measure the output power of the coaxial cable using a power meter.The LGCell is intended for a different frequency band. Verify that your system corresponds to the desired frequency spectrum (for example, 800 MHz, 1800 MHz, or 1900 MHz). Check the part number of each unit.The LGCell is factory set for different bands of operation. Please be sure you have the proper band.The system gain is lower than specification. The optical fiber connector is dirty. Clean the fiber ST-connector, using the manufacturer’s recommended cleaning procedure.There are two types of Multi-Mode Fiber (MMF), 62.5/125 µm and 50/125 µm. Make sure the vertical run MMF is the 62.5/125 µm type of fiber.Remote Antenna Unit (RAU) power LED (green LED) stays off after you plug in the twisted pair cable.The Expansion Hub provides power to the RAU. Make sure the Expansion Hub is on.Make sure that the twisted-pair (TP) cable wiring conforms to the TIA/EIA 568-A standard. (For information about the standard, refer to Appendix B – TIA/EIA 568-A Cabling Standard.) Use a standard local area network (LAN) cable tester to perform this test. Possible errors are wrong wiring and/or cable length.The LGCell performance is intermittent when you use it for the CDMA application.The uplink and downlink gain is not balanced. A CDMA system performs active power control between the base station and the mobile unit. It is important to maintain a balanced link from the base station ports to the RAU ports (equal uplink and downlink gain) to optimize the performance of the LGCell.

6-8 Common Problems, Troubleshooting, and Frequently Asked QuestionsDiagnostic ProceduresUse the following table when diagnosing system problems. While troubleshooting, you can copy the blank table on page 12 and use it to record the LED colors on the Main Hub, the particular Expansion Hub indicating a fault, and the RAUs connected to it. This is necessary because the Main Hub, Expansion Hubs and RAUs might be geographically distributed.To determine where the fault might be1Go to the Main Hub and record the LEDs. The Main Hub indicates which Expansion Hub may be faulty by lighting one of its port LEDs red.2Go to the Expansion Hub attached to the port that has a red LED.3Record that Expansion Hub’s LEDs. The Expansion Hub indicates which RAU(s) may be faulty by lighting its antenna LED red.4Go to the RAU(s) connected to the Expansion Hub port indicating a fault.

6-13Frequently Asked QuestionsThe following list provides answers to some frequently asked questions about LGCell:1What is the LGCell Distributed Antenna System?The LGCell Distributed Antenna System (DAS) contains multiple low-power radiating elements that are deployed around indoor facilities to improve coverage and capacity. The unique, patented architecture of the LGCell DAS provides an inexpensive solution to the cellular and PCS provider for coverage/capacity upgrades and private microcell applications.2What is twisted pair cable? Will it pick up spurious emissions?Twisted pair (TP) cable is the standard cable that you find at the back of your computer for the network hookup. TP cable is the most ubiquitious cable in any office building. Furthermore, TP cable is inexpensive and easy to install. The twisting nature of the cable creates a transmission line for efficient signal transfer and rejection of spurious emissions The LGCell uses a state-of-the-art common-mode rejection device that reduces pickup of spurious emissions on a TP cable by a factor of 10,000.3Can a single LGCell simultaneously support multiple access standards (such as 800 AMPS/TDMA?Yes. The LGCell is a frequency selective product. The LGCell system is transparent to the protocol that the base station and mobile unit use. You can view the entire system with all the cables together as a frequency selective repeater with a specified gain.4What is the bandwidth of the LGCell?LGCell selects from the RF bandwith, which can help prevent amplification of an unwanted signal, such as a competitor’s signal. Refer to the data specifications for the RF bandwith of the system. Another interpretation of bandwidth is the amount of data that the LGCell system can transmit. The microcellular or macrocellular base station to which the LGCell is connected limits the bandwith or capacity of the LGCell, which is a transparent system. Total, composite output power and spurious emissions are the only constraints that limit the amount of channels that an RAU can radiate. Furthermore, the LGCell system shall not limit the data rate of the modulation transmitted through the system.5Can the LGCell support multiband operation?The LGCell provides a wide variety of single-band products, including the U.S. 800 MHz, European GSM 900, DCS 1800, Korean PCS 1800, U.S. PCS 1900 systems, and iDEN. You can use these systems together to provide multiband services. In addition, LGCell has a Dual Band 900/1800 system available.

6-14 Common Problems, Troubleshooting, and Frequently Asked Questions6Can the LGCell system share the same UTP Category 5 Cable with the Ethernet network?No. The LGCell system can use the existing unused cabling inside the building; however, you cannot use the same cable to connect an RAU and a computer.7What is the minimum power input to the Main Hub?The coverage area of an RAU is directly related to the input down link power at the Main Hub. Therefore, an input power that generates an output power of 0dBm per channel optimizes the coverage area of an RAU.8What is the minimum detectable power of an RAU?The minimum detectable power of system with 1 RAU is -114 dBm in a 30 kHz bandwidth, -106 dBm in a 200 kHz bandwidth, and -98 dBm in a 1.25 MHz bandwidth, without taking into account the processing gain of different access standards.9What is the difference between connecting the LGCell to a roof-mounted antenna and to a microcellular base station?Connecting the LGCell to a roof-mounted antenna increases the coverage of the indoor environment. Connecting the LGCell to a microcellular base station improves both the coverage and the capacity in the building and might also provide a private wireless office application for the customer.10 Does each Main Hub require a separate coaxial feed to the base station?A typical RF input power per channel to the Main Hub is 0 dBm. This provides a lot of margin (link budget margin) for interfacing with antennas through a base station that typically has an output power of 20 dBm. Therefore, a power combiner/splitter might be installed between the MH and the base station. This enables one base station to connect to multiple Main Hubs. For details, refer to Section 2, LGCell Equipment.

Appendix B – TIA/EIA 568-A Cabling StandardThis appendix is a summary of the TIA/EIA 568-A Commercial Building Telecommunications Cabling Standard.The TIA/EIA 568-A commercial building cabling standard addresses the need for a common criterion covering cabling in commercial buildings. The standard was drafted to ensure support for a wide variety of applications, devices, and vendor products.The TIA/EIA 568-A standard assures a flexible cabling scheme which permits the planning and installation of communications cable without prior knowledge of the user's needs. This is especially valuable for new building construction and renovation where it is less costly and less disruptive to install a universal cabling system prior to occupancy.The need for a building cabling standard was recognized in the early 1980s. It resulted from the changes brought on by new technologies. The purpose of the original drafting committee was to provide a non-proprietary cabling system for both new and existing facilities.In 1985, the Computer Communications Industry Association approached the Electronic Industry Association (EIA) in regard to the market's confusion over cabling systems. The EIA and later its offspring, the Telecommunications Industry Association (TIA), addressed this via technical working groups comprised of industry participants. The resulting standard 568 addressed performance and safety issues related to technology and utilized many recognized and proven standards.The TIA/EIA 568-A standard defines the categories of UTP cabling, the categories of connecting hardware, patch cables, and provides guidelines on cabling practices.The TIA/EIA 568-A standard describes six sub-systems within a facility telecommunications cabling system summarized below. (This is intended as a summary only and is meant to provide a better comprehension of the standard. The complete TIA/EIA 568-A standard is available for purchase. Call 1-800-854-7179.)

B-2 Appendix B – TIA/EIA 568-A Cabling StandardHorizontal WiringThe horizontal cable is the portion of the cabling system which extends from the work area outlet to the telecommunications closet. The horizontal cabling is a star topology, with a maximum cabling run of 90 meters (295 feet), independent of media type.Voice Data4-pair 100 ohm UTP cable 4-pair 100 ohm UTP/STP2-pair 150 ohm STA62.5/125 µm fiber optic cableThe horizontal cable amounts to the greatest quantity of individual cables in the building. Although the TIA/EIA 568-A standard helps limit cabling options, consideration should be given to media type in order to support possible future needs. The cable selected should accommodate more than one network planning period.Backbone WiringThe backbone cabling provides the interconnection between the tele-communications closets and the equipment rooms and entrance facilities. The backbone cabling is also a star topology with the maximum cable length being media and applications dependent.The backbone cable is typically second to horizontal cables in terms of amount of cable deployed. The cable selected should accommodate a minimum of one to several network planning periods.

B-3HC Horizontal Cross-Connect MC Main Cross-Connect IC Intermediate Cross-ConnectWork AreaThe work area interconnects the horizontal cabling at the wall outlet to the desktop devices. The maximum allowable distance for patch cables is three meters (9.8 feet), based on the cable being of the same type as the horizontal cable.Telecommunications ClosetThe telecommunications closet is the area in a building dedicated to telecommunication equipment. The functions which take place in the closet include the interconnection point between horizontal and backbone cabling systems, the interconnection of two or more backbone cabling systems, and/or the interconnection of the entrance facility to the overall telecommunications cabling system.Note 1When the HC to IC distance is less than maximum, the IC to MC distance for optical fiber can be increased accordingly but the total distance from the HC to the MC shall not exceed the maximum of 2000m (6560 ft.).Note 2When the HC to IC distance is less than maximum, the IC to MC distance for UTP cable can be increased accordingly but the total distance from the HC to the MC shall not exceed the maximum of 800 m (2624 ft).

C-6 Appendix C – Compliance InformationIEC/EN 60825-2 - Safe Use of Optical Fiber Communication SystemsPart 2 of IEC 60825 provides requirements and specific guidance for the safe use of optical fiber communications where optical power may be accessible at some distance from the optical source. In this part of IEC 825, light emitting diodes (LED’s) are included whenever the word “laser” is used.Description of LGCell SystemThe LGCell is a distributed antenna system. It consists of three main components. A Main Hub, which is connected by dual mode fiber optic cables to one or more Expansion Hubs. Each Expansion Hub is connected by UTP CAT 5 cable to a Remote Antenna Unit. Because LED’s are used to send a signal over the fiber optic cable, the LGCell is covered under the IEC 60825 specification.Requirements under IEC 60825Under IEC 60825, LGC Wireless is required to determine the Class of operation of the LGCell system, the Hazard level of the LGCell system and any special instructions that must be included in an operators manual as well as any warning labels that may be required on the LGCell system. The LGCell is covered only under these definitions of section 3 of 60825. 3.2 enclosed system: A system in which, during normal operation, the optical radiation is totally enclosed, by light proof cabinets, components, total internal reflection or optical fiber cables and connectors. 3.3 end user: The person or organization using the optical fiber communication in the manner the system was designed to be used. The user cannot necessarily control the power generated and transmitted within the system. 3.4 hazard level 1: A hazard level 1 is allocated to any part within an optical fiber communication system at which, under reasonably foreseeable circumstances, human access to laser radiation in excess of the accessible emission limits (AEL) of class 1 for the applicable wavelengths and emission duration will not occur. 3.10 light emitting diode (LED): Any semiconductor device which can be made to produce electromagnetic optical radiation in the wavelength range from 180nm to 1mm. (The optical radiation is produced by the process of spontaneous emission, although some stimulated emission may be present.) 3.13 location with controlled access: A location where access to the protective housing (enclosure) is controlled and is accessible only to authorized persons who have received adequate training in laser safety and servicing of the system involved. Examples include optical cable ducts and switching centers.

C-73.14 location with restricted access: A location where access to the protective housing is restricted and not open to the public. Examples include industrial and commercial premises, PBX rooms, computer system rooms, and optical test sets. Distributed fiber networks may pass through unrestricted public areas, restricted areas within premises, as well as controlled areas or they may be deployed entirely within restricted business premises. 3.18 optical fiber communication system: An engineered assembly for the generation, transference, and reception of optical radiation arising from lasers in which the transference is by means of optical fiber for communication purposes. 3.19 reasonable foreseeable event: An event, the occurrence of which under given circumstances can be predicted fairly accurately, and the occurrence of which is a possibility. Examples of reasonably foreseeable events might include the following: fiber cable break, optical connector disconnection, operator error or inattention to safe working practices. Reckless use or use for completely inappropriate purposes is not to be considered as a reasonably foreseeable event.Installation NotesThe LGCell is covered under these parts of section 5 of 608255.2.1.3 Test Equipment: During installation or testing of an optical fiber cable or system, only test equipment of laser Class 1 should be used.5.2.1.5 Installation Rules: Each person engaged in the installation or service of an optical fiber cable communication system should observe all rules, procedures and practices established for the safe operation of optical fiber communication systems.Evaluation of LGC SystemThe LGCell is covered under Annex A of 60825The LGCell system is a self contained product that contains an optical fiber communication system that would be safe under normal operating conditions because the optical radiation is totally enclosed and contained under intended operation. However, because of the extended nature of the system, the optical power may be accessible a kilometer from the optical source. The LGCell system contains LED's, which are the source of radiation covered under IEC 825. Usually a whole fiber optical communication system would not be classified under IEC 825-2 in the same way required under IEC 825-1. This is because, under intended operation, the optical power is totally enclosed, and it could be argued that an interpretation of IEC 825-1 would give a class 1 to all systems, which may not accurately reflect the hazard potential of some systems. If the emitter can be operated separately, it should be classified according to IEC 825-1. However, the power output level of the LGCell system is so low that it always falls into the class 1 hazard level even under 100% modulation conditions. The absolute maximum allowed at 1300nm is +9.5 dBm. The absolute maximum accessible output of the

C-8 Appendix C – Compliance InformationLGCell fiber optic system is -11.5 dBm. Therefore there is no restriction as to location of use of the LGCell system and there is no labeling requirement.Suggested Work PracticesThe LGCell is covered under these parts of section D7 of 60825The following working practices are suggested for working on the LGCell system:•Viewing Fiber: Do not stare with unprotected eyes at the connector ends of the fibers or the ports of the hub.•Test Fibers Cables: When using test fiber optical cables, the optical power source shall be the last to be connected and the first to be disconnected. •Fiber ends: Any unconnected fiber ends should be covered with an approved cap. Do not use tape.•Broken Fiber Cables: Do not stare with unprotected eyes at any broken ends of the fibers. Report and have any broken fiber cables replaced.•Cleaning: Use only approved methods for cleaning optical fiber connectors.•Modification: Do not make any unauthorized modifications to this fiber optical system of associated equipment.•Live work: Live work is permitted on the LGCell as it is a class 1 hazard.•Signs: No warning signs are required.•Test Equipment: Use class 1 test equipment.

E-4 Appendix E – Alarm Report Monitor (ARM2000)ARM2000 System BasicsThe ARM2000 system is an alarm monitoring, reporting, and remote control system. Up to 8,160 individual alarm points can be monitored, displayed and logged by the system. The system consists of up to 255 remote-ARM monitoring units that can monitor up to 2,040 LGC systems (LGCell, PCS Extender, Fiber Extender) and a Pentium PC running the ARM software.These remote-ARM units communicate with the ARM software through dial-up modem connections. Each remote-ARM unit can use an external or internal modem. A database of these devices is set up in the PC, each device having a unique address. This address is set on the device and programmed into the PC using the Device Setup utilities of the software. The next figure illustrates both the direct connection of a single ARM unit and multiple units connected via a dial network.Multiple Remote-ARM Over Dial-up NetworkARM2000-RU (Remote Unit) InstallationThe ARM2000-RU is rack mounted in the same rack as the LGCell Main Hub(s).This remote-ARM unit has an “octopus” cable that enables it to monitor up to 8 LGCell Main Hubs. The ARM unit needs to be within 4 feet of each Main Hub that it will monitor due to the cable length.The ARM unit has an external power supply that requires a 110 VAC receptacle. Connect the power to the ARM unit after all cable and telephone connections are completed.Remote ARM with Internal ModemRemote ARM with Internal ModemDial-upNetwork

E-5Modem ConnectionsCommunications to or from the remote ARM can be configured in either of two ways:•Internal modem (inside remote-ARM unit)The internal modem must be a North American qualified modem for use in telephone networks that use North American standard call progress tones. This modem is inside the remote-ARM unit and requires an analog phone line connection with an RJ-11 male connector. Connect the phone line to the port marked “Line” in COM1, at the back of the remote ARM. •External modem (via RS-232 COM1)LGC Wireless recommends a US Robotics External modem qualified in the country of use. To install this modem, you need a DB-25 to RJ-45 converter cable and a cable with RJ-45 male connectors on both ends.If you are in a country that does not use North American standard call progress tones, you need to use an external modem with the ARM2000-RU unit.If you use the US Robotics External modem, you need to prepare the modem with initialization commands before you use it, as “Preparing the PC Modem” on page 7 describes. Take the following steps to install the modem:1Connect the phone line to the phone line marking at the rear of the modem.2If you choose to be notified by a phone ring of an incoming call, then connect the phone to the phone marking at the rear of the modem via RJ-11 male connectors on both ends.3Connect the DB-25 to RJ-45 converter at the rear of the modem.4Run the other end of the RJ-45 cable to the RS-232 COM1 port at the rear of the remote ARM.Alarm Cable ConnectionsTo connect the LGCell Main Hub(s) to the remote ARM, use the two-to-eight-port connector cable. Make the following connections to monitor the following alarms:Connector Alarm MonitoredJ1 Alarms 1,2 - Main Hub 1J2 Alarms 3,4 - Main Hub 2J3 Alarms 5,6 - Main Hub 3J4 Alarms 7,8 - Main Hub 4J5 Alarms 9,10 – Main Hub 5

E-6 Appendix E – Alarm Report Monitor (ARM2000)J6 Alarms 11,12 – Main Hub 6J7 Alarms 13,14 – Main Hub 7J8 Alarms 15,16 – Main Hub 8Input Alarm input to ARM unitOutput Remote Reset from ARM unitAlarm Cable and ConnectorsTest SetupAfter the ARM unit is powered up, the unit should be reset and ready for communicating to the PCARM system for final programing. When the ARM is powered, wait 15 seconds and then press the TEST button on the left front of the unit. All 16 circuit alarm LEDs on the front panel should light and toggle to green momentarily. If this does not occur, power down the ARM unit for 15 seconds and start over.The LED final state should be green to indicate a proper connection and a no-fault condition for each Main Hub that is also powered up. Each Main Hub has 2 LEDs assigned to it. Alarm circuits that do not have an “octopus” cable connected will be red.

E-7PCARM Programming InformationIf multiple ARM200-RU units are installed that will be controlled by one PCARM system, then each ARM200-RU unit must be configured with a unique device ID (1-255) for programming by the PCARM system. Each ARM unit must have a different device ID if it will be controlled by one PCARM system. There is a label on each ARM unit that indicates what device ID it has be configured for. The device number and which Main Hub(s) it has been connected to, is important information that must be provided to the person programming the PCARM.PCARM Installation for ARM2000The PCARM software runs the ARM2000 system.
