• RAD PW products

• Summary

PW = Pseudowire


Background

RAD’s TDM Pseudowire Products Offering

• Carrier class TDM voice or data over packet networks

• Uniform TDM access across all last mile infrastructures

• Preserves investment in legacy equipment in migration to PSN

• Reduce the costs by avoiding the need to pay for leased lines

• Lowers OpEx of TDM service by utilizing packet infrastructure.

• Carrier grade voice quality (no compression, no Silence Suppression)

Cellular Backhauling Using PW

Market trends:

• E1/T1 bandwidth is insufficient for new Broadband Services (e.g. HSDPA)

• Mobile operators deployed 3G, which requires additional backhaul bandwidth

• Circuit-based 2G co-located with ATM-based 3G

• Network evolution from TDM/ATM to IP/MPLS

• Future IP based Node B’s (3GPP R5/6)

The RAN (Radio Access Network) typically consists of multiple E1/T1 Leased Lines

What is Pseudowire?

• Pseudo = Simulated, Seemingly

• Extends services over PSN (ETH/IP/MPLS)

• Supports voice, data and video

• Provides a transparent tunnel through the PSN

• Defined by IETF PWE3 working groupsTDM PW, ATM PW, FR PW and ETH PW

• Provides clock distribution and synchronization over PSN
