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
ACE Overview TS-2006 Slide 3
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

• 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
