Alcatel-Lucent 1850 TSS-5 Transport Service Switch 9
Figure 3 illustrates a low-cost solution for bringing high-speed access to small
enterprise customers, using DS1/E1 and EoS-protected OC-3 or OC-12 lines,
and aggregating Ethernet connections for transport over FE and GigE.
The 1850 TSS-5 collects traffic from the multiple sources within the building,
aggregates them together and then transmits the aggregated traffic by
SONET/SDH or Ethernet to basement-located customer premises equipment
(CPE) or even directly to the CO.
In this application, the 1850 TSS-5 again excels due to its small footprint and
its support of both TDM and packet. Within the building it supports greater
use of fiber, as opposed to copper, and enables EoS services such as virtual
LAN (VLAN) and Ethernet private lines. In addition, the 1850 TSS-5
supports both electrical and optical Ethernet interfaces, greatly increasing
network-design flexibility.
