With service provider-friendly hardware & mission-specific software, the Cisco ME 3400 Series is the first access switch family optimized for both the Ethernet-to-the-home (ETTH) triple-play services & Ethernet-to-the-business (ETTB) VPN services. It provides the most complete security solution for Metro Ethernet access that covers subscriber, switch, & network protection. The Cisco ME 3400 Series supports multiple software images to provide a "pay-as-you-grow" deployment model. With service breadth spanning triple-play & Layer 2 & Layer 3 VPN services, reduced total cost of ownership (TCO) & operating expenses (Op Ex) can be achieved from a single ETTH + ETTB access solution.
