A
Adaptive Communications Technology (ACT)
A technology that incorporates both radio frequency (RF) and power line
communication (PLC) onto one chip set. Adaptive Communications Technology (ACT)
allows an endpoint to dynamically change its communication media and modulation to
the fastest and most reliable available, based on its location, network operating
conditions, and the criticality of the application data.
Advanced Meter
An electric meter that is capable of measuring and recording usage data in time
differentiated registers, including hourly or such interval as is specified by regulatory

provides other data and functionality that address power quality and other electricity
service issues.
B
Battery Backup Unit (BBU)
The battery provides power to the CGR if AC power is lost or not available. The CGR
supports up to three units.
Battery Powered Device (BPD)
Devices powered by long-lasting batteries, as opposed to mains powered devices
(MPDs), which receive power from a wired electrical connection.
C
Connected Grid Router (CGR)
A Cisco® field area router (FAR) used as a network router in OpenWay systems. The
CGR is a network router that serves as a data collection point for meters participating in
