The Alcatel-Lucent 1850 Transport Service Switch (TSS-3) is a carrier-grade network termination unit (NTU) that provides intelligent Ethernet service demarcation between the end customer and the service provider. It is part of the 1850 TSS family of packet transport products, which offers service differentiation, transport-grade resiliency, and operations, administration and maintenance (OAM) support.

The 1850 TSS-3 provides a mix of connectivity and network services, offering diagnostics, service monitoring, protection, quality of service (QoS), rate limiting, and virtual LAN (VLAN) stacking for Metro Ethernet Forum (MEF) compliant Ethernet services.

Available in six configurations, the 1850 TSS-3 provides a mix of copper and optical Ethernet on the customer side, and optical Ethernet and Ethernet over Plesiochronous Digital Hierarchy (PDH) on the network side.

 Benefits:

• Intelligent Ethernet service demarcation
• Media conversation for Ethernet over any physical uplink
• - Ethernet over fiber
• - Ethernet over PDH, enabling reuse of existing E1/DS1 or E3/DS3 links for sites without fiber
• Quick rollout of carrier Ethernet services
• Rich features for QoS and service differentiation
• Manageable services end-to-end
• Leading-edge services over Ethernet, such as voice over IP (VoIP) and mobility backhaul

Features:

• Fast Ethernet/Gigabit Ethernet (FE/GigE) customer and network interfaces
• Ethernet over PDH network interfaces (E1/DS1, E3/DS3)
• QoS: Traffic classification, rate control and prioritization
• VLAN tagging and stacking
• Uplink redundancy
• Link OAM
• Compact, standalone or rack-mounted
• Standard configurations for simplified deployment
