GDC Innovx NetPath DSLAM-48
Increased Bandwidth through ADSL2/2+ DSL Technology


The recent technology advances have led to largely increased bandwidth capacity for ADSL. GDC’s Innovx
NetPath DSLAM-48 supports the ADSL2/2+ DSL technology.  The NetPath DSLAM-48 delivers a 48-port ADSL2/ ADSL2+ subscriber interface with built-in POTS splitter. In areas where economy or geography does not allow for fiber as access media, the NetPath DSLAM-48 presents the same type of services to the end-user as if connected via any other broadband access technology.
