Agenda The Smart Grid Transport of next generation data over existing networks Transport of legacy data over new networks Voice compression Summary
Smart Grid Solutions Smart Grid = Automation = Communications
Building the Smart Grid Eventually the utility network will be IP/MPLS Eventually all network elements will be Ethernet based But in the meantime. We need to transport Ethernet over legacy networks We need to support legacy data over IP/MPLS
Why Ethernet? New SCADA, telemetry and measuring equipment even teleprotection is based on Ethernet data transmition Video surveillance VoIP Technician corporate network connectivity Management Smart meters Etc.
Ethernet over TDM
Supporting Ethernet over existing network Legacy networks such as E1 & SDH are originally designed for voice New technologies enable efficient transport of Ethernet data over these networks
The problem.. Native Ethernet connectivity is not always available Existing multiplexers and ADMs don t always have Ethernet I/O ports
The Solutions: Standard based media converters for Ethernet over PDH (NG-PDH) Ethernet over SDH Ethernet over copper Forklift upgrade
Fast & Efficient Ethernet Rollout QoS per service - Assures circuit reliability GFP/VCAT/LCAS -low latency, higher throughput and interoperability Sub-Station Analog RTU PDH Mux Data VoI NMS P Central office GbE STM-1 SDH n x E1 Sub-Station Data VoIP NMS n x E1
Utilizing Existing Infrastructure Extending life of radios by enabling transition from TDM to Ethernet Bundles up to 16 E1 (32Mbps) PDH-radio n x E1 n x E1 STM-1 STM-4 SDH-radio STM-1 STM-4
Multiservice platforms Scalable solutions Ethernet and TDM over same network E1/STM-1 Sub-Station Analog RTU Digital RTU Headquarter Sub-Station Analog RTU Router GbE X.21 V.35 E1/T1 STM-1 SDH E1 Digital RTU Sub-Station Analog RTU E1 Digital RTU
Smart Meter Data Collection n x E1 POP BPL Central Site GbE STM-1 POP Wimax GbE STM-1 STM-4 SDH E1 FE POP xdsl STM-1 STM-4 FE/GbE
Smart Meter Data Collection Mostly done by Wireless Aggregated at a regional POP Then Needs to be backhauled over existing SDH network Also, Ethernet based technoligy
Data transport over Dark Infrastructure with Central Site Aggregation E1/Ethernet over fiber using standard SHDSL No standard for E1 over fiber PBX n x n x E1 Control Room STM-1 GbE Control Room Copper 2Mbps Fiber 108 Mbps Copper 22.8 Mbps Fiber 108 Mbps E1 E1 V.3 5 CCTV Pumping Station RS-232 RTU RTU
TDM over IP Pseudowire
Supporting TDM over IP Ethernet/IP networks originally designed for data New technologies enable transport of TDM circuits over IP or Ethernet
Pseudowire Technology - Circuit Extension over The synchronous bit stream is segmented Headers are added to each segment to form the Packet Packets are forwarded to destination over the PSN network At destination, the original bit stream is reconstructed transparently
PseudowireStandards Application Standard IETF ITU-T MEF TDM PW TDMoIP RFC 508 Y.1413, Y.1453, MEF 8 Y.1414, Y.1452 CESoPSN RFC 5086 Y.1413, Y.1453 MEF 8 SAToP RFC 4553 Y.1413, Y.1453 MEF 8 HDLCoPSN HDLC transport Ietf-pwe3- tdmoip None None ATMoPSN ATM service ietf-pwe3-atm- Y.1411 None transport encap Y.1412
