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).
