  27. TDM Emulation over PSN ATM and TDM Pseudo Wire (PW) over Packet Switched Network (PSN) Using DSL Access The need: • Clear dynamic of moving from ATM networks to Packet Switched networks (PSN) • There is a need to take legacy traffic as TDM and ATM over the PSN network. This is commonly done using PW technology and tunneling the traffic over the PSN Implementation Concept • When using DSL access there is a need to start these PW in the CLE because Most DSLAMs do not support PW • Two implementation phases • Working with IP DSLAMs providing Ethernet interface towards the network and keeping ATM based DSL towards the customer • Working with IP DSLAMs providing Ethernet interfaces both towards the network and towards the customer

  28. Now in trials Leased Lines Emulation over IP/ATM/DSL Customer Premises Customer Premises PBX • CESoPSN or TDMoIP tunneling solution • On the receive side the jitter buffer store the payload prior to play-out to the local TDM attachment circuit. The size of this buffer should be locally configurable to allow accommodation to the PSN-specific packet delay variation. • Clock recovery is based on NTR DSLAM DSLAM E1 LA-110 LA-110 E1 PSN Eth/IP/MPLS SHDSL SHDSL PBX Eth Eth GbE TDMoIP Gateway IPmux Gmux TDM CO/POP
