Future Forecast Where is this Technology Going? Prayson Pate CTO Overture Networks Ethernet Over Copper

Not Everyone Has Access to Fiber Ethernet Over Copper

EoC Trends Faster and Farther? Yes Improved rates per pair Bonding multiple pairs Cross Talk Cancellation Vectoring Phantom mode Better? YES! Must have operational features specific to EoC for fastest delivery and lowest operational costs Must be equivalent to other methods of Ethernet access for delivery of services compliant to CE 2.0 Ethernet Over Copper

Reality Check - Predictability Required! The copper plant varies wildly with geography and environment Successful deployment of Ethernet services over copper depends on predictability of rate/reach, co-existence with other services, and advanced tools Reliance on uniform copper plant, short loops and absence of alien interferers is very limiting for business services Ethernet Over Copper

Faster and Farther EoC at PAETEC Application: data center for a social media company. Requirements: High Bandwidth Symmetric Stringent SLA Quick Turnup??? Issue: Couldn t get fiber fast enough and at the right price Ethernet Over Copper

Faster and Farther EoC at PAETEC Solution: Bonded EoC EFM/G.SHDSL 4000 feet from CO 32 pairs @ 6-7 Mbps each Result: 200+ Mbps without pulling fiber Turned up in one day Delivered rate higher than predicted Service was ready when customer moved in Bandwidth is important, but successful deployment requires rich operational features, including planning tools, turnup automation and troubleshooting features 6100 Ethernet Over Copper

Better EoC is a Means, Not an End EoC shines for when fiber is not available for applications such as business services, small cell, private cloud, DSLAM backhaul, but EoC is just one of many technology choices to provide CE 2.0 services with appropriate QoS and reliability Consistent measurement and reporting of SLAs is needed for same level of service across media Ethernet Over Copper

Key EOC Features for Usability Q: Why was the PAETEC application sucessful? A: Service was available on time and per SLA. How? EoC bandwidth is necessary, but not sufficient. Also need: Zero touch Rate adaptive Automatic bonding Sevice OAM Loopbacks Tone/TDR Result: Successful and predicatable high speed deployments across all media (including 200Mbps EoC!)
