  2. Agenda • Introduction • RAD ATM Products • Typical Applications • Key Features • Summary - Worldwide References

  3. ATM Market Trends • ATM still remains a major data transport network technology for incumbent carriers • Carriers can use ATM to generate new revenue using existing infrastructures • Deployment of 3G cellular networks • Continuing growth in DSL leads to increased investments in ATM

  4. Important Benefits of ATM • Proven reliability • Allows flexible multiservice traffic adaptation • Scalability based on existing infrastructure • QoS assurance based on the OAM functionality • Traffic Management - allows network bandwidth utilization • New services based on GbE/MPLS infrastructure are emerging but ATM is still more widespread

  5. Common ATM Applications • Native ATM • Legacy services emulation (LAN, TDM, FR etc.) • VLAN applications over ATM • DSL service concentrator • Cellular backhauling Legacy services Existing CPE’s New services & CPE’s IP, LAN ATM Access Concentrator Ethernet Switch Ethernet NTU PBX-Voice

  18. VLAN Stacking SP VLAN* C VLAN* Frame C VLAN Frame Local Customer Adding SP VLAN according to VC • The ACE acts as an ATM gateway, extending Metro services to remote customers over wide span ATM network • Similarly, the ACE can be used to connect ‘islands’ of metro Ethernet over ATM national network • To allow this application VLAN stacking was added to the ACE so each ATM VC is mapped to a Service Provider (SP) VLAN ACE-2002 ACE-52 Metro Ethernet ATM Network Ethernet STM-1 Remote Customer Removing the SP VLAN Local Customer SP VLAN C VLAN Frame C VLAN Frame *SP VLAN – Service Provider VLAN *C VLAN – Customer VLAN
