Alpha extends its service power inserter family to include the SPI-RF, designed to connect the system power supply and DOCSIS network monitoring device. The SPI-RF includes an RF port allowing connection of the transponder to the cable plant inside Alpha’s enclosures instead of placing a drop into the enclosure. This eliminates the need to have a drop placement of line passive and the associate cost for installation labor. This unit can be configured into Alpha’s PWE, UPE, PN and Node Power enclosures. Also, the SPI-RF can be removed or replaced without removal of the main cable entry assembly. An auxiliary power connection and transfer switch enables system AC power connection from a mobile source during power outages or power supply maintenance. A LED indicates the presence of primary power, and a test point provides for fast measurement of AC voltage.
