In addition to avoid unwanted cross communication between CU
systems that are close to each other the MAUW binds each registered
Agent to his Network ID. A bound Agent refuses to communicate with
other CU/MAUW systems.
To increase reliability an AUW is equipped with a redundant power
supply, to ensure power.
