NIC Modes of Operation
Once the NIC has powered up in the field, it may go into several different modes
of operation. These are depicted in the preceding image. When an outage occurs, it
stops reading the meter and publishing readings. Instead it goes into a
power-conserving mode and sends last-gasp messages. When power is restored, it
goes back into the normal mode and transmits a power restored alarm message.
Similarly, while in the normal operating mode, it can accumulate firmware
download packets and meter reconfiguration files. When the download is
complete, they can be applied. A firmware upgrade causes the module to
temporarily go offline and reboot.
Meter Softswitches
Meter softswitches are configured at the factory. A given switch must be enabled
to unlock certain meter functionality. Once enabled by the meter, the NIC will
support the feature as described in Meter Softswitch Support on page 35.
