SmartJack™

Benefits

SmartJack™

  • Provides full-featured NIU functionality within a form factor that is one half the width of conventional 400 mechanics NIUs
  • Lower power dissipation for optimum heat management

PROACT

  • Provides a unique set of diagnostic messages that isloate trouble to the network side or the customer side of the PMNIU
  • Enables the customer to remotely or locally provision and test the PMNIU
  • Allows PM data to be extracted remotely, in a manner that is non-intrusive to service
  • Provides up to 30 days of perfomance monitoring historical data that is stored in non-volatile memory

Features
