T-Marc 3312SC/SCH NextGen Ethernet/MPLS/ IP Mobile Backhaul Demarcation device offers an all-in-one solution that meets the increasing challenge of mobile operators, and mobile backhaul wholesale and service providers to cost-effectively connect base stations and controller sites combining 2G/3G and 4G infrastructures. 

The T-Marc 3312SC/SCH provides multiple types of services to allow mobile operators to deliver backhaul and business services while standardizing one product.

T-Marc 3312SC/SCH supports IEEE802.1q, Q-in-Q and MPLS transport technologies, providing high flexibility in network design and future proofing the network with no additional software licenses. It provides access to advanced data services such as virtual private wire services (VPWS), VPLS and HVPLS, simplifying the network and making it easier to manage, while gaining MPLS added value.

The T-Marc 3312SC/SCH offers one of the densest demarcation devices on the market, incorporating high capacity in a compact “shoe-box” size (1RU by ½RU width), with 4 x 10/100/1000BaseTx, 8 x dual-speed (100M/1G) fiber ports and 8 x E1/T1 Circuit Emulation Service (CES) ports for 2G/3G migration. The T-Marc 3312SC/SCH supports redundant power supplies (AC/24VDC/48VDC) making it optimal for cell site deployment. T-Marc 3312SCH is the same product as the T-Marc 3312SC, with the addition of BITs in/out interfaces support clock and hardened temperature (-40°C to 65°C / -4°F to 149°F).

Circuit Emulation and Time Synchronization Support

The T-Marc 3312SC/SCH enables service providers to carry native TDM traffic transparently across packet-switched networks (PSN) using various circuit emulation techniques required when converging and migrating 2G and 3G to 4G and newer IP-based mobile technologies.

T-Marc 3312SC/SCH supports both Synchronous Ethernet (SyncE), IEEE 1588v2*, and clock distribution from one source to another*, enabling mobile operators to achieve a solution which can handle the current frequency synchronization requirements needed for 2G and 3G technologies, and future phase synchronization requirements needed for LTE-TDD.

Flexible Control of Traffic and Services

To allow providers to cope more efficiently with the increased demand for bandwidth and a more diverse range of services, the T-Marc 3312SC/SCH embeds sophisticated and flexible QoS and HQoS capabilities, such as hierarchical queuing, rate limiting and traffic shaping, advanced scheduling schemes, and intuitive service-oriented SLA configurations. This allows providers to benefit from the multiplexed nature of Carrier Ethernet, while assuring SLA requirements during traffic congestion.

As an MPLS demarcation device, the T-Marc 3312SC/SCH supports various traffic engineering technologies like LDP and RSVP-TE. These technologies allow providers to engineer data paths based on several attributes, while offering the highest level of protection and assuring that the requested paths can meet the defined SLA requirements. They also ensure fast switchover time to minimize degradation or the interruption of services in case of failure, and provide high availability and sub-50ms resiliency using G.8031, G.8032, FRR, and Fast Ring standards.

OAM Support

The T-Marc 3312SC/SCH supports a broad set of hardwarebased OAM tools to help providers reduce their OPEX and to assure their customers they are meeting the agreed SLA. It supports IEEE 802.1ag Connectivity Fault Management (CFM) and ITU-T Y.1731 allowing service providers to monitor services end-to-end, identify connectivity and performance issues and to isolate problems from a remote location without truck rolls. The device also supports IEEE 802.3ah EFM-OAM at the link-level, and complies with MEF requirements, definitions and monitoring.

Using RFC 2544 based embedded test heads and Y.1564 EtherSAM, the T-Marc 3312SC/SCH enables providers to test services remotely from a central office, thereby reducing costly truck rolls, saving OPEX, and improving service quality.

SDN Support

T-Marc 3312SC/SCH provides full SDN support with comprehensive adoption of NETCONF, the network configuration protocol, and YANG, its data modeling language. It also supports OpenFlow 1.3.1 with a simple software upgrade to ViNOX OS (ordered separately).
