PN 8700-10 InterReach Unison User Guide and Reference Manual 2-1620003-0 Rev. APRELIMINARYSECTION 2 InterReach™ Unison System Description2.1 System OverviewInterReach™ Unison is an intelligent fiber optic wireless networking system that is designed to handle both wireless voice and data communications and provide high-quality, ubiquitous, seamless access to the Cellular or Personal Communications Services (PCS) network in any public or private facility, including:• Campus environments•Airports• Office buildings• Shopping Malls• Hospitals• Public Facilities (convention centers, sports venues, etc.)Unlike other wireless distribution alternatives, Unison is an intelligent active system, using microprocessors to enable key capabilities such as software-selectable band set-tings, automatic gain control, ability to incrementally adjust downlink/uplink gain, end-to-end alarming of all components and the associated cable infrastructure, and a host of additional capabilities.The Unison system supports major Cellular/PCS standards and air interface protocols in use around the world, including:• Frequencies: 800 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz• Protocols: AMPS, TDMA, CDMA, DCS, GSM, EGSM, iDEN, CDPD, EDGE, GPRS, WCDMA
InterReach™ Unison System Description PRELIMINARY2-2 InterReach Unison User Guide and Reference Manual PN 8700-10620003-0 Rev. AKey System Features•Superior RF performance, particularly in the areas of IP3 and noise figure.•High downlink composite power (+26 dBm), IP3 (+38 dBm) and low uplink noise figure (22 dB for a system with 8 RAUs), enables support of a large number of channels and larger coverage footprint per antenna.• The Main Hub and the Expansion Hub are software configurable. Thus, the fre-quency band can be field configured.• The system supports flexible cabling alternatives, allowing the use of either mul-timode or single-mode fiber (in addition to standard Cat-5 or Cat-6 [Cat-5/6] twisted pair). Cabling type can be selected to meet the resident cabling infrastruc-ture of the facility and unique building topologies.•Extended system “reach”. Using multimode fiber, fiber runs can be as long as 1.5 kilometers. Alternately, with single mode fiber the fiber run can be as long as 6 kilometers (creating a total system “wingspan” of 12 kilometers). And the Cat-5/6 twisted pair cable run can be up to 100 meters recommended maximum (150 meters with RF performance degradation).•Flexible RF configuration capabilities, including:• System gain:– Ability to manually set gain in 1 dB steps on both downlink and uplink.• RAU:– RAU uplink and downlink gain can be attenuated 10 dB.– Uplink level control protects the system from input overload and can be optimized for either a single operator or multi-operators/protocols.– VSWR check on RAU reports if there is a problem with the antenna.• The system firmware effectively “future proofs” the product. When any modi-fications are made to the product, including the addition of new software capabili-ties/services, systems that have already been installed can be upgraded simply by downloading new firmware (either locally or remotely).•Extensive OA&M capabilities, including fault isolation to the field replaceable unit, automatic reporting of all warnings and alarms, and user-friendly graphi-cal-user interface OA&M software packages.

APRELIMINARY System Hardware2.2 System HardwareThe InterReach Unison system consists of three modular components:• 19" rack-mountable Main Hub (connects to up to 4 Expansion Hubs)• Converts RF signals to optical on the downlink; optical to RF on the uplink• Microprocessor controlled (for alarms, monitoring, and control)• Software configurable band• Simplex interface to any RF source• System master – periodically polls all downstream units (Expansion Hubs/RAUs) for system status, and automatically reports any warnings/alarms• 19" rack-mountable Expansion Hub (connects to up to 8 Remote Access Units)• Converts optical signals to electrical on the downlink and electrical signals to optical on the uplink• Microprocessor controlled (for alarms, monitoring, and control)• Software configurable band (based on command from Main Hub)• Supplies DC power to RAU•Remote Access Unit (RAU)• Converts electrical signals to RF on the downlink; RF to electrical on the uplink• Microprocessor controlled (for alarms, monitoring, and control)• Protocol/band specific unitsThe minimum configuration of a Unison system is one Main Hub, one Expansion Hub, and one RAU (1-1-1). The maximum configuration of a system is one Main Hub, four Expansion Hubs, and 32 RAUs (1-4-32). Multiple systems can be com-bined to provide larger configurations.
InterReach™ Unison System Description PRELIMINARY2-4 InterReach Unison User Guide and Reference Manual PN 8700-10620003-0 Rev. A2.3 System OA&M CapabilitiesThe InterReach Unison is microprocessor controlled and contains firmware which enables much of the OA&M functionality.Complete alarming, down to the field replaceable unit (i.e., Main Hub, Expansion Hub, Remote Access Unit) and the cabling infrastructure, is available. All events occurring in a system, defined as a Main Hub and all of its associated Expansion Hubs and Remote Access Units, are automatically reported to the Main Hub. The Main Hub monitors system status and communicates that status using the following methods:• Normally closed (NC) alarm contact closures can be tied to standard NC alarm monitoring systems or directly to a base station for alarm monitoring.• The Main Hub’s front panel serial port connects directly to a PC (for local access) or to a modem (for remote access).Figure 2-1 OA&M CommunicationsPSTNRS-232RS-232 EthernetPC/LaptoprunningModemMain HubModemMain HubTCP/IPRS-232ENET/232ConverterCat-5/6RS-232SC/APCMain HubSC/APCRJ-45Expansion HubRJ-45Remote Access UnitFiberMain HubAdminManageror OpsConsoleAdminManager can only initiatecommunications with a remotelymodem calls.Use the OpsConsole for monitoringand receiving communications frominstalled system; it cannot receiveremotely installed systems.
PN 8700-10 Help Hot Line (U.S. only): 1-800-530-9960 2-5620003-0 Rev. APRELIMINARY OA&M Software2.3.1 OA&M SoftwareThe AdminManager software runs on a Laptop PC which is either directly connected to the DB-9 RS-232 male connector on the Main Hub’s front panel or is remotely communicating through a modem that is connected to the DB-9 connector on the Main Hub’s rear panel. The AdminManager communicates with one Main Hub, and its downstream units, at a time.• Connected locally, you can access the Installation Wizard which lets you configure a newly installed system, or access the Configuration Panel which lets you query system status, configure a newly added or swapped unit, or change system parame-ters.• Connected remotely, AdminManager initiates communications with the Main Hub. You can access a read-only Configuration & Maintenance panel which lets you check system status to help you determine if an on-site visit is required.Refer to Section 7 for information about installing and using the AdminManager soft-ware.Alternately, an LGC Wireless OA&M software application called the OpsConsole is available separately. The OpsConsole lets you manage, monitor, and maintain multi-ple sites and systems from a centralized location. This software is described in the OpsConsole User Guide, LGC Wireless part number 8701-10.2.3.2 Configuring, Maintaining, and Monitoring Unison LocallyEach Main Hub, Expansion Hub, and RAU in the system constantly monitors itself and its downstream units for internal fault and warning conditions. The results of the monitoring are stored in memory and compared against new results.The Expansion Hubs monitor their RAUs and store their status in memory. The Main Hub monitors its Expansion Hubs and stores their status and the status of the RAUs in its memory. When a unit detects a change in status, a fault or warning is reported. Faults are indicated locally by red status LEDs, and faults and warnings are reported to the Main Hub and displayed on a PC/laptop, via the Main Hub’s serial port, that is running the AdminManager software.Using AdminManager locally, you can install a new system or new components, change system parameters, and query system status.

APRELIMINARY Monitoring and Maintaining Unison Remotely2.3.3 Monitoring and Maintaining Unison Remotely• Using AdminManager RemotelyYou can use AdminManager to query Unison status via a read-only Configuration & Maintenance panel. You cannot change system parameters or configure system components remotely with AdminManager. (Refer to Figure 2-1 on page 2-4.)• Using OpsConsole RemotelyWhen monitoring the system remotely, any change of state within the system causes the Main Hub to initiate an automatic call-out and report the system status to the OpsConsole. If the host does not acknowledge the connection, the Main Hub issues an automatic call-out every 15 minutes until an auto acknowledge or stan-dard request for status (initiated by the host) is received.Refer to the OpsConsole User Guide, LGC Wireless part number 8701-10, for more information about using the OpsConsole for system monitoring.The following figure illustrates how the system reports its status to AdminManager and the OpsConsole.Figure 2-3 Remote System Monitoring and Reporting ExpansionHubThe Expansion Hub checks its own status and polls each of its RAUs for their status.Each RAU reports its status to the Expansion Hub.• If a fault is detected, the ALARM LED is red.

APRELIMINARY Connecting Contact Alarms to a Unison System6.7 Connecting Contact Alarms to a Unison SystemThe Unison Main Hub can generate (source) two contact alarms as well as sense an external contact alarm.• Alarm SourceThe Main Hub has two alarm contacts, major and minor errors. These contacts are normally-closed (NC) and will open when an internal alarm is detected. • Major error is active when any faults or disconnects are detected.• Minor error is active during a lockout or warning, or when the end-to-end sys-tem test is not valid.•Alarm SenseThe Main Hub can monitor an external alarm contact using this feature. The port can be configured for normally-open (NO) or normally-closed (NC) contacts. The interface expects a set of floating contacts. An external voltage source is not required for this interface. AdminManager or OpsConsole is used to monitor the port status.The following table lists the alarm types, equipment that Unison is connected to, cable(s) used, and the errors (major and/or minor) that are detected.Note that only major errors are supported on MetroReach and LGCell, and that the 5-port Daisy-Chain Alarm Cable supports only major errors as well. Therefore, using the 5-port Daisy-Chain Alarm Cable with equipment that supports both major and minor errors will result in only major errors being detected. This is also the case when using the Alarm Source Daisy-Chain Cable, which supports both major and minor alarms, with MetroReach or LGCell because these systems only support major errors.Alarm Type Unison connected to Cable(s) Used Errors DetectedSource MetroReach 5-port Daisy-Chain Alarm Cable and male-to-male adapter cable that is provided with MetroReachMajorAlarm Source Daisy-Chain Cable MajorSource BTS 5-port Daisy-Chain Alarm Cable MajorAlarm Source Daisy-Chain Cable Major and MinorSource ARM2000 Alarm Source Daisy-Chain Cable Major and MinorSense LGCell 5-port Daisy-Chain Alarm Cable and the Alarm Sense Adapter CableMajorAlarm Source Daisy-Chain Cable and the Alarm Sense Adapter CableMajor
