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 associ-
ated 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 con-
nections to the RJ-45 port.
