Hardened ADSL2/2+ Copper/Fiber Digital Subscriber Line Access Multiplexer (DSLAM)


  • The SRi2000-DSLAM-48 offers a medium port count. It provides the most cost-effective initial investment solution for Traffic and Data Communications Network Service providers.
  • The SRi2000-DSLAM-48 is a 24 port IP based ADSL2+ DSLAM with the POTS splitter built-in. It terminates all the ATM circuits and converts traffic directly to deliver broadband IP services for providers who want to offer high speed access services in low subscriber density locations on existing copper twisted pair telephone, traffic network, and generic copper lines.
  • The SRi2000-DSLAM-48 is also backwards compatible with early versions of ADSL.
  • The SRi2000-DSLAM-48 is compliant with ITU G.992.5, G.992.3, G.992.1. The G.992.5 ADSL2+ technology is an enhanced version of ADSL technology which provides cross-talk free deployment.
