System Hardware Description

– 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.

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
