ETHoPDH/SDH/SONETMarket Trends
• Customers demand higher bandwidth capacity – high growth expected in Ethernet over bonded copper (Europe) and over T3 (US Market)
• Fiber to the business reaches 15% of companies
• Service provider networks are in transition: service providers are implementing IP network transformation projects
• Goal of removing layers from their networks to arrive at an IP/MPLS/Ethernet services layer over integrated Ethernet-WDM optical transport
• Although it will take 15 to 20 years, ATM and SONET/SDH will gradually disappear
• Cellular use TDM link and FE links at the same site, (currently mainly in the US market) will be needed soon in the European market
• 2 main applications:• IP DSLAMs backhauling
• WiMAX BTS backhauling

Ethernet over NG-PDH/SDH/SONET• Ethernet over NG-PDH based on the same GFP, VCAT and LCAS technology used in Ethernet
over NG-SONET/SDH. It is standardized by the ITU-T G.7042, G.7043 and G.8040
• GFP, VCAT and LCAS enables efficient bandwidth utilization and dynamically BW allocation
• Ensures robust traffic delivery
• Automatic error correction and minimal packet re-transmissions
• Fully utilization of contracted bandwidth
• Minimizes service disruptions - hitless traffic restoration
• High service resiliency, low latency – ideal for real-time applications
• Easy interoperability with third-party equipment (standard protocol)
• Enhances statistics collection and alarms indications

• Ethernet Private Line (EPL)• Replaces a TDM Private line• Dedicated UNIs for
Point-to-Point connections• Single Ethernet Virtual
Connection (EVC) per UNI
• Ethernet Virtual Private Line (EVPL)• Replaces Frame Relay or ATM
services• Supports multiple EVCs per UNI• Allows single physical
connection (UNI) to customer premise equipment for multiple virtual connections

IP DSLAM and WiMAX Backhauling over SDH/SONET
• Fast roll-out
• Reduce Opex and Capex by leveraging existing transport infrastructure
• Generate new revenues by expanding new services
• Use of less complex Layer 2 technology (converters and channelized switch) for reduced maintenance costs
• Support for wide range of access data rates
• Reference: Telefonica , Jaztel in Spain and SFR France
