Remote Communication Equipment (RCE)
The base of the TWACS system hierarchy. RCEs consist of the DCSI family of
transponder products. RCEs are located at customer sites and interface TWACS
communication with various end devices such as meters, water heaters, and air
conditioning units to enable automatic meter reading (AMR), load management, or
other functions.
Remote Test Set (RTS)
A TWACS communications test device used at a remote site to communicate locally,
using TWACS, to a transponder over the power line.
Remote Meter Transceiver (RMTR)
An electronic communication device that transmits accumulated data using RF
transmission. Not used with the TWACS-ORION System.
