With increasing reliance on enterprise networking, businesses have become
much more vulnerable to operation-crippling circuit outages. Backup circuits
have become a necessity to protect mission-critical communication links.
Emergency satellite backup circuits have historically taken anywhere from a
few hours to a few days to set up. MIDAS offers automatic circuit restoral,
providing operational backup circuits within a matter of seconds.
One or more MIDAS traffic nodes are installed at each site that requires
backup capability. The typical site equipment consists of:
• Antenna
• RF equipment
• Customer equipment, such as router(s)
• Node Control Modem(s)
• Traffic modem(s)
A typical setup for automatic circuit restoral is illustrated in Figure 2-3.
