The drivers
> Minimize CAPEX & OPEX
• New technology allows to compact huge number of interfaces in
• Central office space reduction
• VSR optics
> Improve flexibility
• pay-as-you-grow approach (from 1024xVC4 to 4096xVC4 in the same shelf)
• pay & install only what you need (SFP plug-in optics)
• SDH and Lambda switch using same hardware
> Offer new services / new generation features
• multi-service approach (integrated data functionalities)
• GMPLS control plane for automatic BOnD and network restoration

1678 MCC – product positioning
1
Traditional Ring:
• Stacked 2.5, 10G rings in metro-core
• Multi-ring termination (DCS) in metro-core (2.5G - 40G)
2 Compact BB DCS for switching capacity up to 4K STM1-eq.
Optical switch in OTH core backbone.
Meshed network:
• Centralized and distributed Restoration
• GMPLS for dynamic bandwidth allocation

1678 MCC – benefits in the networks
> Office modernization
• ADM and BB-DXC in one only box
• 60% to 80% price reduction with respect to old gen DCS
• No longer multi-rack configurations: 4K capacity in one compact shelf
> Networks simplification
• Only one NE and one Network Layer for Network Management
• Restoration CAPEX reduction due to port savings
• Automatic bandwidth allocation & distributed protection save Network operators’ manual intervention
• Integrated data functionalities (GbE ptp and L2 switch)

End-to-end provisioning Challenges
“Delays in provisioning have been attributed to the manual process involvedin formulating routes based on specific constraints, determining if there is enough capacity to support the route, and manually provisioning each segment of the route. Historically these functions have been manually supported by network operators andplanners and have been supplemented by network management systems.” (RHK)

Network optimization: how to bring flexibility in SDH
> Traditional SDH/SONET
• Fixed bandwidth (STSx granularity)
• End to End provisioning (Point & Click)
> Virtual Optical Networks
• Flexible bandwidth & routing
• “Customer” monitoring and/or (re)provisioning
> Bandwidth “on Demand”
• Dynamic bandwidth & routing
• GMPLS (OIF-UNI) based interfacing
• Overlay
> Dynamic peer-to-peer
• GMPLS (Control Plane)

Configuration examples
1) HO multi–Ring application: n stacked 2F or 4F rings @ STM-256/64/16 level with drop @ STM-16/4/1 level
2) Compact cross–connect application:
1678 MCC alone
“cluster” made of several OMSNs (1678SM, 1660SM etc...) and a 1678 MCC up to 4K cross–connect with HO/LO interfaces
