For enterprise services, the advantages of installing the 1850 TSS-5 include:
•Saves space, courtesy of the small footprint and avoiding the use of separate data switches
•Uses low-cost fiber terminations at the customer site
•Supports a variety of connection types and speeds, offering service flexibility
•Offers remote operations and monitoring from the central office (CO)
•Provides SONET/SDH-based protection for both voice and data
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.
