T-Metro
Carrier Ethernet Multiservice Access Platform

Enlarge

The T-Metro is a feature-rich multiservice access device, designed to increase service provider revenues and deliver a complete portfolio of voice data and video services.

The T-Metro family of products supports Wide variety of technologies including Ethernet, Circuit Emulation (CES), MPLS, OAM (operations, administration and maintenance) tools and Hierarchical QoS (H-QoS). This rich combination of technologies allows service providers to deliver enhanced service offering while maintaining competitive pricing.

The T-Metro provides access to advanced data services such as virtual private LAN services (VPLS), virtual private wire services (VPWS) and IP virtual private network (IP-VPN) services. In addition, the T-Metro product line enables service providers to transparently carry native TDM traffic across the packet switched network (PSN) using circuit emulation services (CESoPSN). The TDM traffic is encapsulated in Ethernet or MPLS frames to preserve the full array of framing and signaling protocols, ensuring that no enhanced TDM features are lost.

The T-Metro’s unique combination of features, technologies and manageability allow service providers to extend the service intelligence to the customer edge. Doing so, the T-Metro allows service providers to offer and maintain advanced SLA offerings to their customers, thus providing them competitive advantage.

Designed for Metro Ethernet services
Convergence of voice, data and video services over a single Ethernet-based infrastructure, is transforming the way enterprises and service providers conduct their businesses. The T-Metro’s versatility, advanced feature-set, wire-speed performance and robust design makes it an ideal convergence platform for metro applications, either in a bridged metro Ethernet or MPLS environment.

The T-Metro allows service providers to offer seamless access to converged services networks thus enhances their competitiveness.

Bringing service intelligence to the customer’s doorstep
The H-QoS functionality provided by the T-Metro allows service providers to deploy versatile and innovative service offerings. H-QoS provides maximal control over bandwidth shared by multiple services. H-QOS guarantees isolation and fairness between services and customers. Combined with a rich OAM features and elaborate MPLS capabilities, service providers are now able to extend intelligent services to the customer’s edge and offer higher-margin SLA-based services.

Compact, Cost-Effective Metro-Ethernet Access Rings
Deployment of Metro-Ethernet rings becomes increasingly popular due to its efficiency, costs savings, and flexibility. Ring architecture allows for multiple services to be consolidated, transported, and drop/inserted as needed. The inherent redundancy, resiliency and re-routing capabilities of ring technology results in increased reliability and high network availability.

The T-Metro offers an Ethernet ring solution with recovery time of less than 50ms in either bridged metro Ethernet environment or MPLS environment. T-Metro’s Ethernet ring implementation is fully standard based therefore it is fully interoperable with other standard-based products deployed in the same ring.
