Back-up Test
– continuous self-monitoring of controller and all subsystems. Anoma-
lies are reported to NMC. Major faults cause the controller to shut down the repeater
Heartbeat
– a special trap/message is transmitted regularly (transmission inter-val
set by user via GUI, See Figure 5-34 in Section 5) to the NMC. This message indi-
cates to the NMC operator that the repeater is alive; a valid connection exists
between the repeater and the NMC
, and the repeater main controller is operational.
Local/remote software upgrade – software upgrade is initiated via a web browser
by directly uploading the upgrade file to the controller
. When the file is success-
fully received, the web server task will invoke the upgrade procedure. Upgrade
applies to any of the controller softw
are components or any of the other system
components.
Parameter database clearing in EEPROM will return to default settings.
The functional physical components of the controller are:
Main Controller microprocessor chip MPC860x
Supervisor Processor microprocessor chip ATmega2560
GPS receiver
Dial-up modem
Ethernet Switch
Internal UPS
