On Request Reading
The customer configuration worksheet defines what the NIC will generate in
response to an on-request read. (This is done by placing “OR” in the cells which
indicate the desired readings.) The following image describes how a message is
issued by the user at the headend to a DCU near the NIC.
Figure 5.5
On Request Read Sequence
The DCU converts the message to RF and transmits it to the NIC. The NIC
processes the request by fetching fresh readings from the meter. It transmits the
response to the DCU. The DCU buffers and sends the message over the backhaul
to the headend.
