Alcatel-Lucent 1850 TSS-3 Transport Service Switch6
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exible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.
