| 20110148203 | Smart Power Switch For Broadband Communications Network - A power switching module provides power to a line amplifier in a broadband telecommunications network. The switch includes a first input port for connection to a first power source, a second input port for connection to a second power source, an input/output port for connection to a cable connecting the line amplifier with a remote amplifier, and an output port for connection to the line amplifier. A controller controls selection of the power source and provides power to the line amplifier from one the input ports and can provide power to, or receive power from, a power supply associated with the remote amplifier via the input/output port. A switch allows selection of a primary mode of operation or a secondary mode of operation. Another switch allows selection of a first operating voltage range or a second voltage operating range. A monitoring circuit communicates status information about the switching module to a remote location. Monitored parameters include, for example, power supply status, module humidity and temperature. | 06-23-2011 |
