Overture 6500 Open Service Delivery

CE2.0 Ethernet Switching and Aggregation for Any Access

The 6500 is the first and only platform that consolidates switching and aggregation for Carrier Ethernet E-LINE, E-LAN, E-Access and IP services over
fiber, bonded copper, TDM and SONET. The 6500’s ability to deliver service over any access from a single platform saves you money and simplifies your day-to-day operation.

Most Scalable Metro Edge Platform

With configurations for tens to hundreds of customer endpoints and supporting over 3000 unique subscriber service instances, the 6500 is ideal for a range of deployment scenarios at the metro edge. The 6500 is architected with both centralized and distributed switching to minimize entry cost for low bandwidth services without compromising performance for high bandwidth services. Available in three chassis size variants, the 6500 family gives you a common solution for every application, without stranding capital. 

Comprehensive Resiliency

Downtime is unacceptable at the metro edge. The 6500’s high-availability architecture, including redundant switch/control plane modules and redundant distributed A/B powering, means your customers won’t lose service – period. Additional features like cross-card link aggregation, cross card G.8032 v2 rings and cross-card bonding of copper interfaces and TDM circuits allows you to sell services that survive network failures. The 6500 even supports multi-site redundancy to protect against outages that could affect entire geographic areas.

Ready for Software-Defined Services

With a fully programmable data path, and open application programming interfaces (APIs), the Overture 6500 is also the entry point for Ensemble OSA, Overture’s open architecture for software-defined services at the metro edge. An open, multi-layered architecture, Ensemble OSA optimizes service creation, activation and assurance, creating an environment for rapid service innovation, reduced operational complexity, and lower costs through automation. Embracing the principles of software defined networking (SDN) and network function virtualization (NFV), service providers are able to maximize operational efficiencies and introduce new revenue-generating services faster and easier than ever before.

The Overture 6500 makes it easy for service providers to deploy reliable Carrier Ethernet 2.0 at the metro edge. It can deliver differentiated, performance-assured services over any access, at any scale. The 6500 provides service providers with the features they need for an entrance to a smarter network.
