T-Marc 3312SC

NextGen Ethernet/MPLS Mobile Backhaul Demarcation


The T-Marc 3312SC NextGen Ethernet/MPLS Mobile Backhaul Demarcation 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 networks.
T-Marc 3312SC provides multiple types of services to allow mobile operators to deliver backhaul and business services while standardizing through one product. T-Marc 3312SC supports 802.1q, QinQ and MPLS transport technologies – providing high flexibility in technology selection and network thus future-proofing the product with no extra licensing costs. 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 offers one of the densest demarcation devices on the market, incorporating high capacity in a compact “shoe-box” size (1RU by ½RU width), with 4x10/100/1000BaseTx, 8 dual-speed (100M/1G) fiber ports and 8xE1/T1 Circuit Emulation Services (CES) ports for 2G/3G migration.

The T-Marc 3312SC supports redundant power supplies (AC/24VDC/-48VDC) making it optimal for cell site deployment.
