HERNDON, Va. -- XO Communications (OTCBB: XOHO) today announced it is now offering Carrier Ethernet access to its extensive nationwide Ethernet infrastructure (reaching nearly four million buildings) via its new service connectivity with CENX, operator of the world’s first Carrier Ethernet exchange. Connecting with CENX enables the global Carrier Ethernet community connectivity at bandwidths from 3 Mbps to 10 Gbps to locations served by XO.

Carrier Ethernet connection to and from XO Communications’ large footprint is now seamless and simple with CENX’s connection and integration services. XO Communications Ethernet services are offered with demanding SLAs and granular bandwidth options in more than 75 metropolitan cities and to the vast footprint where XO delivers last-mile Ethernet over copper. Reaching XO-served locations operating at speeds as low as 3 Mbps opens up large numbers of new economical business service opportunities to customers connected via the CENX exchange.

“Connecting to the growing number of Ethernet service providers via CENX simplifies complex service level interactions and allows us to leverage our continuing investment in Ethernet services.” said XO’s Don MacNeil, vice president of XO Carrier Services Operations. “Key factors in our decision to work with CENX were its expertise, standardized approach to service alignment and service assurance.”

“We are very excited to establish this very important connection with XO, which enables significant revenue and cost-savings opportunities for both XO Communications and all of our Carrier Ethernet Exchange members,” said Nan Chen, CENX co-founder and CEO. “CENX’s Carrier Ethernet exchanges are the world’s first operational service-level interconnects. By leveraging several unique technical innovations and our years of Ethernet expertise, CENX exchanges address the key operational and business challenges faced by our customers.”
