Like other members of the T-Marc family, the T-Marc 280 supports advanced Layer 2 networking using Telco Systems' AccessEthernet® technology to allow total flexibility in deployment, provisioning, and delivery of Carrier Ethernet services.

Two tri-speed customer access ports enable providers to support two separate customers on a single device. The second access port may also be used to create a DMZ (demilitarized zone or data management zone) to separate external (public) traffic from the customer’s internal network. Each access port supports a single EVC and UNI with four traffic classes. Dual network uplinks include an SFP-based fiber and a combo tri-speed/fiber port. The dual network ports provide a rich set of protection options, including link aggregation, resilient, link, and Spanning Tree protocols.

Standards-based Ethernet OAM features include IEEE 802.3ah link OAM, IEEE 802.1ag connectivity fault management, and ITU-T Y.1731 fault and performance monitoring for end-to-end Ethernet services. Physical and virtual networking capabilities provide automated address management and discovery, bandwidth profiles, advanced traffic classes, and complete control over how subscriber traffic is transported across a service provider’s network.
