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.

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
