The T-Marc 3348S/SH 10GE ETHERNET/MPLS/IP demarcation device offers an all-in-one solution  that meets the increasing challenges of mobile operators, mobile backhaul wholesalers, and service providers  to cost effectively connect base stations and controller sites  running LTE and LTE Advanced. The T-Marc 3348S/SH also offers enterprises 10GE connectivity for heavy duty cloud applications. The device supports IEEE 802.1q, Q-in-Q, and MPLS transport technologies with no licensing fees, increasing network flexibility and future-proofing the network while reducing technological risks. The T-Marc 3348S/SH provides  access to advanced data  services such  as virtual private wire services (VPWS), virtual private LAN services (VPLS) and hierarchical virtual private LAN services (HVPLS), simplifying the network and making it easier to manage, while gaining the added value that MPLS provides.
The T-Marc 3348S/SH is an advanced 10GE demarcation device, incorporating high capacity in a compact size (1RU by ½RU width), with 4 x 1GE/10GE SFP+ ports  (two active ports  and two ports  which require license  activation), 8 x dual-speed. (100Mbps/1GE) fiber ports and 4 x 10/100/1000Mbps copper  ports, it offers one of the densest capacity demarcation devices in the industry. The T-Marc 3348S/SH supports redundant power supplies,  including wide range  DC power input, making it optimal for mobile cell site deployments.

Assuring SLAs using Enhanced Traffic Engineering

As the demand for bandwidth increases, but revenue  streams stay flat, service providers  want to differentiate their services and provide a proper quality of experience (QoE) for various application requirements. A wide set of QoS and HQoS features enable  service providers  to have granular control over the behavior of traffic and services in their networks,  including WRED, multi-level queues, rate limiters and shapers. The T-Marc 3348S/SH supports multiple traffic engineering and dynamic  signaling  technologies, like LDP, BGP and RSVP-TE, so that providers  are able to engineer data paths based on multiple attributes, while assuring that the requested paths can meet  defined SLA requirements.

L3 Support

T-Marc 3348S/SH provides  comprehensive solutions and services that best support IP (Internet Protocol)  environment requirements– including Virt Routing and Forwarding  (VRF) support, IP static routing and dynamic  ro protocols like OSPF and BGP. T-Marc 3348S/SH also supports Dynamic Host Configuration Protocol (DHCP) for dynamically distributing network configuration parameters, and Virtual Router Redundancy Protocol (VRRP).
Advanced Hardware-based OAM over Carrier Ethernet & MPLS

By embedding a comprehensive set of OAM and SLA monitoring and testing tools in its hardware, the T-Marc 3348S/SH provides  real-time accurate network measurements and service turn-up testing and verification, reducing  truck rolls and shortening time for activation and management. The device supports a wide range  of industry OAM standards, including link level IEEE 802.3ah EFM, 802.1ag Connectivity Fault Management (CFM) protocols and ITU-T Y.1731 loss and delay measurement, as well as Y.1731 SLM for E-LAN testing,  and RFC2544 and Y.1564 and MEF46 Latching Loopback  for service activation testing.

Carrier Grade Resiliency

Telco Systems’  T-Marc 3348S/SH provides  carrier grade  resiliency in physical design  and by a variety of resiliency protocols. It is one of few 10GE devices that can provide a protected 10GE ring design  (2x10GE east, 2x10GE west). With a high port count, the T-Marc 3348S/SH offers link-level protection mechanisms (Resilient link, LAG/MC-LAG, FRR, dual homing), network-wide mechanisms (xSTP, G.8032), and service-level mechanisms (G.8031).

Enhanced Synchronization and Timing

As part of the RAN evolution for LTE and LTE Advanced, backhaul networks require strict synchronization of both frequency and phase. T-Marc 3348S/ SH provides  Synchronous Ethernet  (SyncE) optimized for the needs of mobile operators and mobile backhaul wholesale providers. T-Marc 3348SH offers additional BITs in/out clock interfaces and hardened temperature of -40°C to 65°C / -40°F to 149°F often needed for mobile backhaul applications.

SDN Support

T-Marc 3348S/SH provides full SDN support with comprehensive adoption of NETCONF, the network configuration protocol, and YANG, its data modeling language.
