2.1 System Overview

InterReach Fusion is an intelligent fiber optics/CATV, multi-band (frequencies) wire­less networking system designed to handle both wireless voice and data communica­tions over licensed frequencies. It provides high-quality, ubiquitous, seamless access
to the wireless network in smaller buildings.

Fusion provides RF characteristics designed for large public and private facilities
such as campus environments, airports, shopping malls, subways, convention centers,
sports venues, and so on. Fusion uses 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 componen ts and the asso ci­ated cable infrastructure, and a host of additional capabilities.

The Fusion system supports major wireless standards and air interface protocols in
use around the world, including:

• Frequencies: 800 MHz, 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz

• Voice Protocols: AMPS, TDMA, CDMA, GSM/EGSM,WCDMA, iDEN

• Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV-DO,
and Paging

System Overview

The Fusion system supports three 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, Band 2, and Band 3

frequencies to support various world areas, that is 800 MHz/900 MHz/1900MHz
for North America or 900 MHz/2100 MHz and 900 MHz/1800 MHz for Europe
and Asia. Refer to Figure 2-7 on page 2-8 for a specific list of these RAU fre­quency combinations.

• Band 3 (only used for the North Ameri can FSN-8090 19-1 RAU) whose Band 3 is
a 6 MHz sub-band of the 35 MHz Band with Band 1 being an 18 MHz sub-band of
the 35 MHz Band.

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 75 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.

• Firmware Updates are downloaded (either locally or rem otely) 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, except for

the One Port Main Hub configuration that supports 1 Expansion Hub)

• 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 polls 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 com man ds from the Main Hub)

• Supplies DC power 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, 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 com­bined to provide larger configurations.

NOTE: The Fusion One Port Main Hub (PN: FSN-1-MH-1P) configuration
is a cost reduced version of the Fusion Main Hub and supports only one

System OA&M Capabilities Overview

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.

or monitor a local or a remote

about installing and using AdminBrowser software.

2.3.1 System Monitoring and Reporting

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

When a Main or Expansion 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 Main Hub’s RJ-45 port. Passive antennas connected to the RAUs are not moni­tored automatically. Perform a System Test to retriev e status info rm ation about
antennas.

Using AdminBrowser, you can install a new system or new components, change sys­tem parameters, and query system status. Figure 2-4 illustrates how the system
reports its status to AdminBrowser.

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 7-55.

2.4 System Connectivity

The double star architecture of the Fusion system, illustrated in Figure 2-5, 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.
