System Hardware Description
•RAU:
RAU uplink and downlink gain can be independently attenuated 0 or 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.
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 inter-
face OA&M software package.
2.2 System Hardware Description
The InterReach Fusion Wideband system consists of three modular components:
19" rack-mountable Main Hub (connects 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
Periodically polls all downstream 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 commands 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 Wideband system is one Main Hub, one
Expansion Hub, and one RAU (1-1-1). The maximum configuration of a system is
