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 = AutomationSmart GridSmart 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

n x E1

Fast & Efficient Ethernet Rollout

• QoS per service - Assures circuit reliability

• GFP/VCAT/LCAS - low latency, higher throughput and

interoperability

Utilizing Existing Infrastructure

• Extending life of radios by enabling transition from

TDM to Ethernet

• Bundles up to 16 E1 (32Mbps)

• Mostly done by Wireless

• Aggregated at a regional POP

Then…

• Needs to be backhauled over existing SDH

• Also, Ethernet based technoligy

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 ETH

• 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

Voice optimization

• Voice trunking, not Voice switching

• Up to 60% bandwidth saving compared to VoIP

• Works over E1 or IP circuits

• Transparent to PBX signaling
