System Hardware Description
– 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 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 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 com-
bined to provide larger configurations.
