TRANSPORTSERVICESWITCH|RELEASE5.1
The Alcatel-Lucent 1850 Transport Service Switch (TSS-5) is a compact, modular, Packet-Optical Transport
switch serving TDM and packet traffic from T1/E1 to Gigabit Ethernet (GE). More than a traditional multiservice
provisioning platform (MSPP), the Alcatel-Lucent 1850 TSS-5 supports pseudowire emulation edge to edge
(PWE3) for T1/E1 circuit emulation services (CES) over Ethernet uplinks. This combination of pseudowire support
of CES, native Ethernet transport and native TDM transport with Ethernet over SONET/SDH allows service pro-
viders to transform their networks with a mix of SONET/SDH and Ethernet appropriate to their service profile.
Service providers can gracefully migrate their TDM traffic to Packet-Optical Transport using this compact, cost-
effective platform.
Particularly suitable for mobility-backhaul
applications and TDM and Ethernet
services aggregation in general, the
Alcatel-Lucent 1850 TSS-5 is further
applicable to any market where TDM
andCarrierEthernetservicescoexist.
An integral part of the broader Alcatel-
Lucent 1850 TSS portfolio, the Alcatel-
Lucent 1850 TSS-5 operates in the
access/aggregation layer and feeds
into higher-capacity Alcatel-Lucent
Packet-Optical Transport products,
such as the Alcatel-Lucent 1850 TSS-100
andAlcatel-Lucent1850TSS-320.
