The Itron C1SC is a one-way transmitter used for the Cellnet fixed network technology. The
personality module transmits a formatted data packet consisting of the preamble, the utility
billing ID, kWh information, and Cyclic Redundancy Checks (CRC) to ensure message
integrity. The module also features built in power outage notification, reverse power flow
detection, power restoration notification, and redundant transmissions. The C1SC uses
spread spectrum to broadcast its message in the 902 to 928 MHz frequency range once
every five minutes.
Figure 28: CENTRON C1SC
The C1SC is factory programmed to include the utility billing ID, LAN Address ID, and
Register configuration. The utility billing ID is a value decided upon by the utility and
Cellnet. The LAN address is a value that is assigned by Itron and programmed into every
meter within the network. LAN addresses and utility billing IDs are unique to each meter.
Itron activates the LAN ID upon receipt of the meter association file.
