CAM3S/CAM3M Overview
This section provides information about the modules. In general, the CAM3S/CAM3M provides
connectivity to supported devices, like Electricity Meters, and Battery Powered Devices, on the
Itron OpenWay® Riva Communication system when installed into a CGR. See OpenWay®
Riva Communication System Overview .
The CGR ACT Module (CAM) resides inside the Cisco
®
CGR and acts as the root-node within
the network, routing packets and information from meters or grid devices between the Adaptive
Communication Technology (ACT) network and the headend (OWOC-CM). The
CAM3S/CAM3M supports adaptive communications, that allows meters and grid devices to
interact with each other while dynamically switching between Radio Frequency (RF) and Power
Line Carrier (PLC) to ensure the fastest and most reliable path.
In addition to the module residing in the CGR. The CGR contains two operating systems: a
Cisco
®
Internetwork Operating system (IOS) and a Cisco
®
Guest Operating System (GOS).
The IOS runs on the CGR and enables data communications between network nodes. The GOS
runs on the CGR and provides a virtual connectivity. The IOS forwards traffic from GOS through
regular IPforwarding mechanisms. Furthermore, the ACTD firmware runs on the CGR. The
ACTD firmware servers as a communication gateway between the CGR's operating system
(IOS) and the CAM3S/CAM3M. Also, the CAM3S/CAM3M also contains its own firmware. The
CAM3S/CAM3M firmware provides communication to the smart meters. When the CGR is
deployed in a star configuration with Battery Powered Device (BPD), a remote antenna is
required to ensure optimal radio performance. See figure.
