The Overture 4200/4300 series delivers GigE, fast Ethernet and DS1 pseudowire over Carrier Ethernet infrastructure. With industry leading Ethernet OAM and flexible interface options, the Overture 4200/4300 delivers all the capability needed for mobile  backhaul, enterprise access and infrastructure applications.

G.8032 Ring Increased fiber efficiency with sub-50ms protection switching for applications that require protection justlike SONET/SDH.
MEF18 certified DS1 circuit emulation High-performance DS1 circuit emulation is required for mobile backhaul, voice switch and VoIP gatewaytrunks, SS7 circuits, and private line applications. MEF18 certification.
Hardened Deploy in demanding evironments like outside plant cabinets or unconditioned equipment closets.
802.1ag, Y.1731 Continuous, real-time moitoring of fault and performance on every EVC is required for network service management and SLA reporting.
99.999% availability Five-9’s availability is the mark of true carrier class services. Meet customer up-time requirements and reduce the operational cost of truck rolls.

Simplified Services Deployment
Simplify your network with Ethernet and DS1 circuit emulation services on a single converged solution. Deliver MEF18 certified high-performance DS1 circuit emulation services with a choice of integrated 1588v2 or precision-tuned adaptive timing. Deploy in any location with a hardened compact design that can be deployed in outside plant cabinets and tight spaces. Reduce truck rolls with a 99.999% availability solution.

Reliability and Performance
Don’t compromise on reliability and performance as you move from SONET/SDH to Carrier Ethernet. The Overture 4200/4300 G.8032 Ethernet ring provides sub-50ms protection switching. MEF18-certified DS1 circuit emulation meets the same rigorous performance standards as SONET. Designed for 99.999% availability with industrial grade components and redundant hotswappable power supplies; this compact, temperature-hardened product is meant for the most demanding carrier environments.

Market Leading Features
The Overture 4200/4300 provides differentiated service with 64 EVCs, H-QoS, 8-dedicated queues per EVC, Ingress and Egress policing and dynamic p-bit marking. Provide differentiated SLA management with complete 802.3ah, 802.1ag and Y.1731 Service  OAM and 192 MEPs. MEF 18 certified DS1 circuit emulation provides more cost effective DS1 service delivery compared with SONET or router based solutions. Sub-50ms protection switching from G.8032 will impress your customers who demand SONET-level performance.
