discovery of defects, with a detailed description of such defects, (b) Purchaser has obtained a
Return Materials Authorization (RMA) from Seller, which RMA Seller agrees to provide
Purchaser promptly upon request, (c) the defective Goods are returned to Seller,
transportation and other applicable charges prepaid by the Purchaser, and (d) Seller’s
examination of such Goods discloses to its reasonable satisfaction that defects were not

2.1 System Overview
InterReach Fusion is an intelligent fiber optics/CATV, multi-band (frequencies) wire-
less networking system designed to handle both wireless voice and data communica-
tions 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 components and the associ-
ated 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
• Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV-DO,
and Paging

System Overview
2-2 InterReach Fusion Installation, Operation, and Reference Manual
CONFIDENTIAL D-620TBD-0-20 Rev A
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.
