Interface connection

Physical connection

  • 2 x RJ45 connections 

Connection mode

  • Serial monitoring between ATU-R and ATU-C
  • Simulation of ATU-R with simultaneous monitoring
  • Simulation of ATU-C with simultaneous monitoring

Analysis Functions

Interface management

  • Physical parameters
  • Acquisition in PDU mode:
    • Automatic cells Reassembly function
    • One event for each CPCS-PDU.

Protocol event generation

  • Both directions
  • Time stamping: 0.1 microsecond
  • PDU filtering:
    • VPI/VCI values

  Statistics event generation

  • Sampling at a user specified value (in sec)

  • Counters by PDUs type 

Protocol specification for display

Protocol stack with 7 decoding levels:
  • Cells / CPCS-PDU header
  • Protocol stack with 7 decoding levels:
    • PPP / PPPoE
    • IP, TCP...

Data simulation
