SECTION 2 InterReach Unison System
Description
InterReach Unison is an intelligent fiber optic/Cat-5/5E/6 wireless networking system
designed to handle both wireless voice and data communications and provide
high-quality, ubiquitous, seamless access to the wireless network in any public or private facility, including:
• Campus environments
• Airports
• Office buildings
• Shopping malls
• Hospitals
• Subways
• Public facilities (convention centers, sports venues, and so on.)
Unlike other wireless distribution alternatives, Unison is an intelligent, active system,
using microprocessors to enable key capabilities such as software-selectable band settings, 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 wireless standards and air interface protocols in
use around the world, including:
• Frequencies: 800 MHz, 900 MHz, 1700 MHz, 1800 MHz, 1900 MHz, 2100 MHz
• Voice Protocol s: AMPS, TDMA, CDMA, GSM, iDEN,
• Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV-DO,
and Paging

Key System Features
• Superior RF performance, particularly in the areas of IP3 and noise figure.
• High downlink composite power and low uplink noise figure for support of a
large number of channels and larger coverage footprint per antenna.
• Software configurable Main and Expansion Hubs. Thus, the frequency band can
be configured in the field.
• Either single-mode or multi-mode fiber can be used, supporting flexible cabling
alternatives (in addition to standard Cat-5, Cat-5E, or Cat-6 screened twisted pair
[ScTP]). You can select the cabling type to meet the resident cabling infrastructure
of the facility and unique building topologies.
• Extended system “reach.” Using single-mode fiber, fiber runs can be as long as
6 kilometers (creating a total system “wingspan” of 12 kilometers). Alternately,
with multi-mode fiber, fiber runs can be as long as 1.5 kilometers. The Cat-5/5E/6
ScTP cable run can be up to 100 meters recommended maximum, or up to 170
meters when using a Cat-5 Extender.
• Flexible RF configuration capabilities, including:
• System gain:
– Ability to manually set gain in 1 dB steps, from 0 to 15 dB, on both down-
link and uplink.
•RAU:
– RAU uplink and downlink gain can be independently attenuated 10 dB.
– Uplink level control protects the system from input overload and can be
optimized for either a single operator or multiple operators/protocols.
– VSWR check on RAU reports if there is a disconnected antenna (all RAUs
except UMTS-1).
• Firmware Updates are downloaded (either locally or remotely) to operating sys-
tems when any modifications are made to the product, including the addition of
new software capabilities/services.
• Extensive OA&M capabilities, including fault isolation to the field replaceable

2.1 System Hardware
The InterReach Unison system consists of three modular components:
• 19" rack-mountable Main Hub (connects to up to 4 Expansion Hubs)
• RF signal conversion to optical on the downlink; optical to RF on the uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Software configurable band
• Simplex interface to RF source
• System master – periodically polls all downstream units (Expansion
Hubs/RAUs) for system status, and automatically reports any fault or warning
conditions
• 19" rack-mountable Expansion Hub (connects to up to 8 Remote Access Units)
• Optical signal conversion to electrical on the downlink; electrical 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
System Hardware
• Remote Access Unit (RAU)
• Electrical signal conversion to RF on the downlink; RF to electrical on the
uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Protocol/band specific units
The 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). You can combine multiple systems to provide larger configurations.

2.2 System OA&M Capabilities
The InterReach Unison is microprocessor controlled and contains firmware which
enables much of the OA&M functionality.
Complete alarming, down to the field replaceable unit (that is, 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) or normally open (NO) alarm contacts can be tied to standard 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).

System OA&M Capabilities
LGC Wireless offers two OA&M packages: AdminManager and OpsConsole. Both
run on a PC/laptop.
• AdminManager communicates with one Main Hub, and its downstream units, at a
time. Using AdminManager connected locally or remotely, you can configure a
newly installed system, change system parameters, perform an end-to-end system
test, or query system status.
Refer to the AdminManager User Manual (PN 8810-10) for information about
installing and using the AdminManager software.
• OpsConsole lets you manage, monitor, and maintain multiple sites and systems
from a centralized remote location. This software is described in the OpsConsole
User Guide (PN 8800-10).

2.2.1 OA&M Software
2.2.1.1 Configuring, Maintaining, and Monitoring Unison Locally
Each 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 this
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 both faults and warnings are
reported to the Main Hub and displayed on a PC/laptop, using the Main Hub’s serial
port, that is running the AdminManager software. Passive antennas connected to the
RAUs are not monitored automatically. Perform the System Test in order to retrieve
status information about antennas.
Using AdminManager locally, you can install a new system or new components,
change system parameters, and query system status. Figure 2-3 illustrates how the
system reports its status to AdminManager.

2.2.1.2 Monitoring and Maintaining Unison Remotely
• Using AdminManager Remotely
You can use AdminManager remotely to call into the Main Hub and query current
status, change parameters, or command system end-to-end test. You cannot use
AdminManager to continuously monitor system state changes.
• Using OpsConsole Remotely
When 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. The Main Hub calls out three times, each with a 45 second
interval. If the call is not acknowledged in these three tries, the Main Hub waits 15
minutes and continues the above sequence until the call is acknowledged.
Refer to the OpsConsole User Manual (PN 8800-10) for more information about
using OpsConsole for remote system monitoring.
Figure 2-4 illustrates how the system reports its status to AdminManager and the
OpsConsole.

2.2.2 Using Alarm Contacts
You can connect the DB-9 female connector on the rear panel of the Main Hub to a
local base station or to a daisy-chained series of Unison, LGCell, and/or MetroReach
Focus systems.
• When you connect MetroReach Focus or a BTS to Unison, the Unison Main Hub
is the output of the alarms (alarm source) and MetroReach Focus or the BTS is the
input (alarm sense). This is described in Section 7.7.1 on page 7-43. The following
figure shows using MetroReach Focus as the input of Unison contact closures.
