Mobility Backhaul
The 1850 TSS-5 supports backhaul for all wireless technologies, including:

Mobility second-generation mobile system (2G) and 3G traffic is accommodated using Ethernet or
SONET/SDH transport. In addition, its aggregation capabilities allow the 1850 TSS-5 to backhaul
multiple parallel networks simultaneously. With a SONET/SDH network, TDM traffic is carried
in native mode and Ethernet is carried by industry-proven Ethernet over SONET/SDH (EoS).
As mobility traffic and applications become increasingly data and IP oriented, Ethernet backhaul
networks become more attractive. The 1850 TSS-5 offers feature-rich Ethernet services of up to
GigE. (see Figure 1).
