Celpe Implements Metro Network Using RAD’s Ethernet Ring Technology

Megaplex-2100 Access Multiplexers Enable Smart Grid-Ready Automated Environment Complying with IEC 61850


Sao Paulo, Brazil, September 12, 2012 – Celpe (Companhia Energética de Pernambuco), the concessionaire responsible for electric power distribution to more than 3.2 million customers in 184 cities in Brazil’s Pernambuco state, in addition to Fernando de Noronha island and the city of Pedra de Fogo in the state of Paraíba, has rolled out a suite of advanced communications services over a new Metro Ethernet optical network based on Ethernet ring technology from RAD Data Communications.

Twenty-eight of RAD’s Megaplex-2100 multiservice access platforms, connected over fiber optic lines, are used to connect the new network, which replaces an old PDH structure that was installed a decade ago. With this new Metro network, Celpe increases its traffic capacity from 2 Mbps to 100 Mbps, and can now offer unified data, voice, video communications, tele-command, and remote monitoring of its power generation facility.

In addition, by employing RAD’s TDMoIP® pseudowire circuit emulation, the entire Celpe Metro-LAN network is now able to transport advanced IP services, as well as those elements that are still based on TDM legacy circuits. The new network offers traffic redundancy for better service availability, and reduces operational expenses (OpEx) by enabling remote access and configuration of the network devices.

“RAD’s TDMoIP technology allows us to migrate our network over our existing infrastructure,” explains Maurício Moraes Lobo Santos, Celpe Telecommunications Manager. “It’s a perfect fit to meet the demands of both IP and legacy services,” he continues. “At the same time, the multiplexers also provide the mechanism for transmitting our future Smart Grid traffic using our existing resources.”

According to Lobo, another important benefit of the project is its total compliance with the IEC 61850 recommendation, which defines the rules for utility network automation systems. “This is a critical condition to position our network as future-ready, not only with regard to technical aspects, but also standardization,” he notes.

The new IP structure supports operational communications tasks as well, including the transport of data from SCADA (supervisory control and data acquisition) systems, which is collected from 27 separate substations in the Recife metropolitan region, where Celpe integrated operations center is located.

The Metro network also supports IP QoS (Quality of Service) measurement and management applications that protect the substations, as well as the automation of distribution. Celpe expects that by the end of 2015 it will have at least another ten substations integrated into the network.


AXCESS+ Portfolio
RAD’s Megaplex-2100 devices are flexible, modular, hybrid TDM and Ethernet multiplexers, enabling integration of voice, ISDN, video, data, and LAN services over multiple E1/T1s, Ethernet uplinks or n x 64 lines. The Megaplex main links and user ports incorporate copper, CSU/DSU, LTU, and fiber interfaces, and are compatible with RAD’s standalone intelligent SHDSL.bis modems and TDM network termination units. The Megaplex-2100 is an element in RAD’s AXCESS+ portfolio for multiservice access and First Mile applications.

About Celpe
Celpe engages in the generation and distribution of electric power, serving 184 municipalities of Pernambuco, the archipelago of Fernando de Noronha and the city Pedra de Fogo in Paraíba state. Celpe production facility is comprised of two 138/69 KV and 129 69/13.8 KV substations, all of which are fully automated. The company utilizes 3,960 kilometers of transmission lines and 121,000 kilometers of distribution branches, with 103,000 distribution transformers. By the end of 2012, Celpe will also have 160 automated distribution points, controlling its entire structure from a single distribution center located in the city of Recife. In 2011, Celpe’s total revenue stood at nearly US$ 2.34 billion, with US$152 million in profit. For further information, please visit www.celpe.com.br
