Alcatel-Lucent 1850 TSS-3 Transport Service Switch 6
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.
Key features
• Versatile mix of Fast Ethernet (FE) and GigE interfaces
• Available Ethernet over PDH (EoPDH) network interfaces
• Traffic classification, rate control and prioritization
• VLAN tagging and stacking
• Uplink redundancy
• Hardware-based Ethernet service OAM (ITU-T Y.1731)
• Ethernet in the First Mile (EFM, IEEE 802.3ah) and Con-
nectivity Fault Management (CFM, IEEE 802.1ag)
• Compact, standalone or rack mounted
• Standard configurations simplify deployment
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.
