Power Utilities Migration Challenges


Power Utilities Migration Challenges

• Legacy Equipment Obsolescence– Support and spare parts for legacy installed base become a challenge

• Sycamore, Coastcom, Carrier Access, Nortel, Alcatel’s Mainstreet, Tellabs, Nokia, JungleMux, Adtran and etc.

– Need to use the existing legacy backbone (SONET/SDH/PDH/sub-E1/T1…)– New equipment should fully interop with existing devices, support

ongoing services

• Analog or TDM Leased Line Service Termination by Telcos– SDH/SONET equipment and legacy services are being phased out


New Challenges

• Smart Applications and New Packet Services – New digital control devices/IEDs, Syncrophasors, IoT (Internet of Things)– Bandwidth growth, migration to IEC 61850– UTelco services

• Security! Security! Security!– US NERC CIP regulations – Critical infrastructure

Full interop with existing equipment

Hybrid design for adding new packet services

Up to 100Gbps all packet with OTN/DWDM, robust performance

New Carrier Ethernet 2.0, any voice, video, data

Secure-by-design: MACsec, IPSec, 802.1x authentication, distributed SCADA firewall …

Interoperability Challenges Addressed

• N x 64 kbps path protection • Rate adaptation for sub-64k services • Differential protection control signaling using legacy interfaces (X.21, V.35, etc.)• Clock distribution within network• SCADA servers redundancy mechanism• Variety of PHY

>> RAD’s SAN solutions address all these challenges…

Analog/Leased Line Service Termination


Challenges to Utilities

• Service providers attempt to reduce OpEx by terminating legacy services and leased lines, issue “End of Service” notices

• Utilities are offered to migrate to new PSN services, or pay premium for legacy lines

• Utilities should assure: – Continued support for all existing services (serial/voice/data)– Cyber security (PSN is opening the door to malware threats)– Future-proof design (capacity and scalability)

From Legacy TDM to Next-GenerationPacket Networks


Optimized Packet Technology –Carrier Ethernet

• Carrier Ethernet is the packet equivalent to SONET/SDH because:– It utilizes EVCs, which are similar to VTs and VCs– It uses OAM for seamless troubleshooting, similar to SONET/SDH OAM

• Best security compared to PSN alternatives:– Resistant to signaling attacks– Built-in source authentication– Integrated security

RAD’s Evolutionary PathAddressing Utility Communications Challenges

• Continued support for TDM• Future ready, hybrid TDM and Ethernet design• Ethernet over SONET/SDH and pseudowire for a smooth migration – Cross

Generation implementation• Traffic Duplication for improved latency and increased resiliency• Carrier-grade Ethernet for performance assurance of the operational network,

with better security, and timing distribution
