The T-Marc 3208SH service demarcation device is a temperature-hardened, Carrier Ethernet demarcation device to enable service providers and wireless operators to backhaul traffic from multiple 2G, 3G and 4G cell sites over Carrier Ethernet. This device supports a wide variety of technologies including Ethernet, pseudowire and TDM emulation using Circuit Emulation Services (CES), MPLS, OAM tools and H-QoS. This combination of features, technologies and manageability allows service providers to extend the service intelligence to the customer edge offering and maintaining advanced SLAs, thus providing them competitive advantage.

The 3208SH provides a comprehensive set of synchronization options optimized for cellular operators looking to backhaul their data and voice traffic from the Node-B\BTS to their core network over Ethernet\MPLS transport. The device supports Synchronous Ethernet (SyncE), IEEE 1588v2, external clock and phase source via BITS interfaces and clock distribution from one source to another for all source types. This flexibility allows any cellular operator to achieve a synchronization solution suitable for his own needs.

A wide set of QoS and H-QoS features enable the service provider to have a granular control over the behavior of traffic and services in the network. Service multiplexing enables service providers to deliver multiple, isolated, services on a per-port and/or a per-flow basis. Provisioning, monitoring and troubleshooting of each individual service can be done without impacting other services.

The 3208Sh supports 8 dual PHY Gigabit Ethernet interfaces, 4 dual-speed (100/1000) Ethernet plug-in (SFP) ports, Sync Clock and Phase Clock Coaxial interfaces and two expansion slots for add-on line cards.
