The Positron G.hn Access Multiplexer (GAM) family includes rugged versions for deployment in harsh environments (outdoor) where there is no local power source. These GAM devices obtain their power from the G1001-MR over the copper wiring or G1001-CR over the COAX cabling. The outdoor GAM devices offer the same feature and management capabilities as their indoor counterpart. They optimize coverage of Gigabit Internet services in an MDU and operate over twisted-pair cabling in Point-to-Point mode while operation over a coax infrastructure is in Point-to-Multipoint mode where each COAX port can serve up to sixteen (16) G1001-CR devices. The GAM-4-CR has four (4) COAX ports and supports RPF mode from G1001-CR devices, one or more (in Point-to-Multipoint mode) per G.hn port. Support for RPF facilitates the installation of the GAM outside of the MDU and in areas where it is not simple or cost effective to install a local power source.
