Alcatel-Lucent 1850 TSS-5 Transport Service Switch 8
The 1850 TSS-5 supports graceful migration from
TDM 2G services to fast-growing Ethernet- and
data-oriented 3G services. With Ethernet back-
haul, the 1850 TSS-5 supports TDM traffic by
CES. In CES, TDM is transported over Ethernet
by static multiprotocol label switching (MPLS)
pseudo-wires protected by bidirectional forwarding
detection (BFD), a form of label switched path
(LSP) protection.
By using the 1850 TSS-5, businesses avoid making
a premature SONET/SDH or Ethernet backhaul
decision. They can start with SONET/SDH
backhaul networks and move to Ethernet
backhaul as packet traffic grows, transitioning
from TDM backhaul to Ethernet backhaul on the
same platform, where and when it makes sense.
Enterprise Services
The 1850 TSS-5 provides a low-cost solution for
offering high-speed access to small and medium-
sized enterprises. The 1850 TSS-5 provides
businesses and service providers with reliable
transport for both voice and data service. Figure 2
shows the 1850 TSS-5 placed in various buildings
with diverse multitenant units. Separate users have
distinct voice and data requirements, needing a
mix of DS1/E1 and Ethernet connections.
