9. Market Trend: Cellular Operators move the Tradtional RAN to IP-RAN, Why? • Backhaul of BSS/UTRAN is one of the major contributors to the high cost of building out and running a mobile network. • Cellular operators have massive deployment of PDH/SDH traffic, most reliable solution for GSM and R’99 UMTS backhaul. • PDH/SDH Mobile Backhaul solution does not seem flexible enough to efficiently deliver statistical/bursty traffic. Cellular operators would like to maximize revenues and margins by converging mobile flows over a unified Packet Switched Network infrastructure in order to reduce both Capex and Opex by using PW.

10. What is PW? • Pseudowire is a mechanism that emulates the essential attributes of a telecommunications service over a packet-switched network • TDM leased line, ATM or ETH • It defines a way to packetize and encapsulate data and create a logical link between two network entities • Pseudowire technology is an enabler for the migration scenarios, with circuit and service emulation of legacy services over packet networks PWE3 #1 PWE3 #2 PSN TDM ATM HDLC, ETH etc. TDM ATM HDLC, ETH etc. Tunnel CLE/CPE CLE/CPE Service Service Pseudowire Emulated Service
