Summary

This chapter discussed one of the predominant IP migration methods for today’s mobile networks. Whether driven by technological or financial decisions, backhaul network evolution to IP-based mechanisms is a clear operator strategy, and pseudowire transport mechanisms provide a bridge between the legacy TDM systems presented in Chapter 2 and the All IP systems presented in Chapter 3. Although not without their share of complexity, including time and frequency synchronization, IP backhaul networks are an obvious value to mobile operators. With such a large number of solutions for both pseudowire transport and synchronization, mobile operators need to understand the technologies themselves and determine which best meets their requirements.
