OverviewFeaturesSpecificationsKey ApplicationsLiteratureSupport
The T-Metro family of products supports a wide variety of technologies including Ethernet, Pseudowire, and MPLS, OAM (operations, administration and maintenance) tools and extensive QoS capabilities. This rich combination of technologies allows service providers to deliver enhanced service offering while maintaining competitive pricing.

The 7124S 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 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.
The 7124S supports industry-standards IEEE 802.1ag Connectivity Fault Management (CFM) and ITU-T Y.1731 allowing the service provider to monitor end-to-end services, identify connectivity and performance issues and isolate the problem from a remote location without truck rolls. The 7124S provides a wide set of QoS features that enables the service provider to have a granular control over the behavior of traffic and services in the network.

The 7124S supports 24 dual-speed (100/1000) Ethernet plug-in (SFP) ports and one expansion slot for add-on line cards.
