  2. Agenda • Introduction • Typical applications of RAD PW products • RAD PW products • Summary PW = Pseudowire

  3. 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) Packet Network PW GW PW GW TDM Service TDM Service Pseudowire

  4. Leased Line PSN TDMoIP Solution – Campus Environment Application:Carrying PBX traffic over campus ETH network Benefits: • Using PSN to provide voice services • Saves leased line costs • Preserving legacy TDM equipment, features and functionalities Building 1 Building 2 PBX PBX LAN LAN

  5. BSC/RNC Radio Stations RAN 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

  6. Different Services over PSN Solution 3G • Multiplex mixed-generation links to a common transport • Convert between circuit, cell and packet • Transport of a legacy service over IP/MPLS tunnels • Multiplexing/aggregation of multiple services over PSN ATM ACE 2G TDM Cellular Services PSN GW PBX IPmux PSN Eth/IP/MPLS E1 TDM DSL Services VoIP LA DSL

  7. 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
