  1. Combining Ethernet and Circuit Services presented at

  2. Overview • Ethernet transport is a key enabler for Ethernet (& IP) services • Uniquely meets most stringent service requirements • Improve service coverage and time to market • Accommodates today’s transport infrastructure and enables for future migration • Key applications in • Residential triple play backbones • Wireless access/backhaul • Data center networking • Resilient access to switched/routed data services networks

  3. Background To reduce operating and capital expenditures, many enterprises are considering consolidating their voice, data, and video traffic onto a single converged, packet-based network Despite the availability of Ethernet metro and WAN services, many enterprises are still searching for solutions that fully address their evolving requirements Revenues from traditional frame relay, ATM and TDM private line services delivered over separate network infrastructures continue to shrink, but will take a long time to disappear Co-existence of Ethernet and other services is a necessity !!

  4. Challenges for Carriers Carrier Challenges Carrier Ethernet Solution Scalability (MACs, VLANs, Nodes) Differentiated services on one network Carrier-class Service migration EoMPLS Hard QoS Non-stop reliability Service interworking Carrier Ethernet solutions respond to carrier challenges

  12. Sync and Incumbent Carriers Incumbent carriers will want... • High-quality sync --> Potential differentiator (or maintain parity) • Predictable, reliable, deterministic sync...not traffic-dependent • Proven technology, low risk (conservative approach) • Hierarchical clock distribution which derives from SONET/SDH • Easy fit: Similar OSS & craft setup and management • Always operate at the lowest feasible network level • Reliability • Quality • Low incremental CapEx • Predictions: • #1 Choice: CES Sync (Available now, but not "Layer 1," not forklift) • #2 Choice: Synchronous Ethernet ("Layer 1," but not available now, and forklift) • #3 Choice: IEEE 1588v2 ("Layer 2, and not available now, and forklift) • Wildcard: Cheap GPS!
