Mobility Backhaul

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

•Code Division Multiple Access (CDMA)

•Global System for Mobile Communications/Universal Mobile Telecommunications

System (GSM/UMTS)

•Wideband Code Division Multiple Access (W-CDMA)

•Worldwide Interoperability for Microwave Access (WiMAX)

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).
