Ethernet service management
The 1850 TSS-3 goes beyond simple media conver- sion and physical presence, providing a rich mix of connectivity and network services, offering diagnos- tics, service monitoring, protection, quality of service (QoS), rate limiting and VLAN stacking for Metro Ethernet Forum (MEF)-compliant Ethernet services.
Available in a number of standard configurations, the 1850 TSS-3 offers a flexible mix of copper and optical Ethernet on the customer side, and
supports optical Ethernet and EoPDH on the
network side.
In addition, the 1850 TSS-3 supports wire-speed Ethernet switching,
network redundancy on Ethernet and PDH uplinks, and standards- based operations, administration and maintenance (OAM). Hard ware-based Ethernet OAM provides precise QoS measurements for superior SLA support.
With multiple off-the-shelf configurations and applications, the Alcatel-Lucent 1850 TSS-3 offers new-service revenue streams at a very competitive price. It comes with rich functionality, including discovery and auto-negotiation of OAM, link monitoring and remote fault indication.
The 1850 TSS-3 acts as a fully non-blocking Ethernet switch, including rate-control and control-protocol processing rules. It also offers Ethernet QoS, as defined by the service provider, at the CPE demarca- tion point. Service differentiation becomes possible and time-sensitive traffic is given precedence. Finally, a variety of redundancy schemes are available, depending upon the application chosen. All this makes the Alcatel-Lucent 1850 TSS-3 a leading CPE device.
