Multiservice Transport

Highlights

	Delivers a range of multiservice transport platforms, optimized for the access edge to the metro core, that support integrated Ethernet and TDM services over carrier-grade SONET/SDH
	Offers significant cost, reliability, manageability, and interoperability advantages over other network architectures
	Provides interfaces ranging from DS1/E1 to OC-192/STM-64, plus 10/100/1000 Mbps Ethernet to 10 GbE
	Supports point-to-point, linear, UPSR/SNCP and BLSR/MS-SP ring, and multiple ring topologies

Overview

Service providers are facing a transitional period in their access networks. Traditional TDM interfaces aren’t going away, yet there exists an ever-growing need to also support and deliver Ethernet. This requirement to incorporate Ethernet may manifest itself externally through customer requests for Ethernet transport services, or it may be driven internally by the need to streamline rollouts of new revenue-generating IP services, such as video and internet access.

The need for TDM and Ethernet is can been seen at network aggregation points such as central offices, POPs, Remote cabinets, cell sites, and colocation sites that require TDM/PDH interface to support legacy voice and data services, along with the need for 10/100/1000 Mbps Ethernet and 10 GbE interfaces for new packet-based services.

Integrated TDM and Ethernet

To support Ethernet and TDM access, a service provider has two fundamental options; build and maintain two separate networks - one for Ethernet and one for TDM, or transition to an integrated Ethernet/TDM network based upon the widely deployed SONET/SDH infrastructure and Ethernet over SONET/SDH (EoS). The latter option is an integrated approach offers several benefits, including:


	Lower cost, easier to manage Only a single, converged network must to be managed and maintained, resulting in lower operational and capital expenses.
	Greater Resiliency SONET/SDH-based transport ensures restoration from network outages in less than 50 milliseconds for all services.
	Superior Fault Isolation Ethernet over SONET/SDH supports all the useful alarming, fault isolation and OAM capabilities associated with SONET/SDH. These capabilities are still evolving for Ethernet.
	Interoperability SONET/SDH and Ethernet over SONET/SDH technologies are industry standards, offering proven interoperability.
	Incremental Migration An Ethernet over SONET/SDH architecture is optimized for today’s requirement for Ethernet in the access/aggregation network, as it allows incremental migration to carrier Ethernet and WDM in the core.

The Turin Solution

Turin Networks provides a wide range of multiservice transport solutions designed for applications from the access edge to the metro core. Turin’s products offer interfaces from DS1/E1 to OC-192/STM-64, plus 10/100/1000 Mbps to 10 Gbps Ethernet, with support for point-to-point, linear, UPSR/SNCP and BLSR/MS-SP ring, and multiple ring topologies. Scalable STS-1/VC-3 and VT/VC-12 level switching enables complete “any-to-any” grooming across any combination of multiple integrated rings and drops. The versatile Traverse® and TraverseEdge™ product families allow service providers to deploy a truly integrated carrier Ethernet and SONET/SDH transport solution that offers increased Ethernet bandwidth and flexibility coupled with carrier-grade optical transport.
