System Overview

The Fusion system supports two configurable bands:

• Band 1 in 35 MHz and can be configured for 850 MHz, or 900 MHz.

• Band 2 in 75 MHz and can be configured for 1800 MHz, 1900 MHz, or 2100 MHz

Both bands support all protocols.
Fusion remote access units contain combinations of Band 1 and Band 2 frequencies to

support various world areas, that is 850 MHz/1900MHz for North America or 900
MHz/2100 MHz for Europe and Asia. Refer to Figure 4-3 on page 4-6 for a specific
list of these RAU frequency combinations.

Key System Features

• Multi-Band, supports two or more full band frequencies for spectrum growth.

• Superior RF performance, particularly in the areas of IP3 and noise figure.

• High downlink composite power and low uplink noise figure enables support of
a large number of channels and larger coverage footprint per antenna.

• Software configurable Main and Expansion Hubs allow the frequency bands to be
configured in the field.

• Either single-mode or multi-mode fiber can be used, supporting flexible cabling
alternatives (in addition to standard CATV 74 Ohm cabling). You can select the
cabling type to met the resident cabling infrastructure of the facility and unique
building topologies.

• Extended system “reach.” Using single-mode fiber, fiber runs can be a long as 6
kilometers (creating a total system “wingspan” of 12 kilometers). Alternatively,
with multi-mode fiber, fiber runs can be as long as 500 meters.

• Standard 75 Ohm CATV cable, can be run up to 150 meters for RG-59 cable
(170 meters for RG-6; 275 meters for RG-11 using CommScope 2065V, 2279V,
and 2293K cables).

• 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 in 1

dB steps.

– 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.

CONFIDENTIAL D-620TBD-0-20 Rev A

• Firmware Updates are downloaded (either locally or remotely) to the system

when any modifications are made to the product, including the addition of new
software capabilities and services.

• OA&M capabilities, including fault isolation to the field replaceable unit, report-

ing of all fault and warning conditions, and user-friendly web browser user inter­face OA&M software package.

2.2 System Hardware Description

The InterReach Fusion system consists of three modular components:

• 19" rack-mountable Main Hub (connect s to up to 4 Expansion Hubs)

• Converts RF signals to optical IF on the downlink; optical IF-to-RF on the
uplink

• Microprocessor controlled (for alarms, monitoring, and control)

• Auto-configurable bands

• Simplex interface to RF source

• Periodical ly pol ls all downstream RAUs for system status, and automatically
reports any fault or warning conditions

System Hardware Description

• 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 commands from the Main Hub)

• Supplies DC pow er to RAUs over CATV cable.

• Remote Access Unit (RAU)

• Converts IF signals to RF on the downlink; RF-to-IF on the uplink

• Microprocessor controlled (for alarms, monitoring, and control)

• Multi-band protocol independent, frequency specific units

The minimum configuration of a Fusion system is one Main Hub, one Expansion
Hub, four Expansion Hubs, and one RAU (1-1). The maximum configuration of a
system is one Main Hub and 32 RAUs (1-4-32). Multiple systems can be combined to
provide larger configurations.

System OA&M Capabilities Overview

Figure 2-1 Fusion System Hardware

2.3 System OA&M Capabilities Overview

InterReach Fusion is microprocessor controlled and contains firmware to enable much of
the operations, administration, and maintenance (OA&M) functionality .

Complete alarming, down to the field replaceable unit (that is, Fusion Main Hub,
Expansion Hub, and Remote Access Unit) and the cabling infrastructure, is available.
All events occurring in a system, defined as a Fusion 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 basic alarm monitoring.

• Connection Methods:

• The Main Hub’s front panel RJ-45 port connects directly to a PC (for local
Ethernet access).

• The Main Hub’s front panel RS-232 serial port connects directly to a modem
(for remote access).

• Remote access is also available with an optional 100BASE-T LAN switch con­nections to the RJ-45 port.

AdminBrowser OA&M software runs on the Fusion Main Hub microprocessor and
communicates to its downstream RAUs. Using AdminBrowser, you can perform the
following:

• Configure a newly instal led system

• Change sy stem parameters

• Perform an end-to-end system test

• Query system status from any standard web browser (Internet Explorer) running
on your PC/laptop system.

Refer to the AdminBrowser User Manual (D-620607-0-20 Rev A) for information
about installing and using AdminBrowser software.

2.3.1 System Monitoring and Reporting

Each Fusion Hub in the system constantly monitors itself and its downstream RAUs
for internal fault and warning conditions. The results of this monitoring are stored in
memory and compared against new results.

When a Hub detects a change in status, it reports a fault or warning alarm. Faults are
also indicated locally by red status LEDs. Both faults and warnings are reported to
AdminBrowser software and displayed on a PC/laptop connected to the Hub’s RJ-45

Fusion Main

Hub

AdminBrowser

The Main Hub queries
status of each Expan­sion Hub and each
RAU and compares it
to previously stored
status.

If a fault is detected,
LEDs on the front panel
turn red.

You can connect the DB-9 female connector on the rear panel of the Fusion Main
Hub to a local base station or to a daisy-chained series of Fusion and/or MetroReach
Focus systems.

When you connect MetroReach Focus or a BTS to the Fusion, the Fusion Main Hub
outputs the alarms (alarm source) and MetroReach Focus or the BTS receives the
alarms (alarm sense). This is described in Section 7.7.1 on page 7-48.

2.4 System Connectivity

The double star architecture of the Fusion system, illustrated in Figure 2-4, provides
excellent system scalability and reliability. The system requires only one pair of
fibers for eight antenna points. This makes any system expansion, such as adding an

extra antenna for additional coverage, potentially as easy as pulling an extra CATV
cable.
