Interface Connection

Physical Interface

  • Ethernet 802.3 interfaces 10/100M
  • One Data link (B channel) over ISDN BRI and PRI interfaces
  • One Data link over V24, V35, V36, X24  interfaces.
  • One data-channel (1 TS) + One data-channel (1-31 aggregated TS) over E1 interfaces
  • One data-channel (1 TS) + One data-channel (1-24 aggregated TS) over T1 interfaces
  • Two data-channels (VCC) over STM1 & E3 interfaces
  • One data-channel (VCC) over ADSL interface

Analysis Functions

Protocol Event Generation

  • Ethernet: MAC 802.3 events,
  • Vseries Asynchronous  events
  • E1, T1 Data channel:  BOP events,
  • ATM: CS-PDU events

Statistics Event Generation

  • Event counters
  • Counters by PDUs type on IP, TCP...
  • Data-flow counters for low layer

Protocol Specification for Display

  • Each channel specified with a protocol stack of 7 decoding levels:
    • MAC / BOP envelope,
    • IP layers decoding:
      • LCP,  PPP, Cl-IP
      • IP family: TCP, PAP, CHAP, ARP
      • IPX
    • H323 family: 
      • TPKT, H225, H245, T123, T125, RAS, RTP, RTCP, X224
      • Full H323 ASN1 PER decoding
      • IP addresses, UDP/TCP port identifications
  • Event-Editor functions for events formatting and  filtering
