The upgrade did not result in a subscription price increase for participants of either exchange, said Lennart Oly, ENX managing director.
Stanbaugh said a November survey of about 250 member companies of ANX revealed that they were satisfied with the exchange's product and service but wanted to communicate with the same reliability with European customers and suppliers.
He said about half the members share engineering designs and data over the exchange. They also use it to process purchase orders and health care claims data and even for credit processing. The data sent are too sensitive to trust to standard Internet connections.
Trubiquity, a suburban Detroit company that helps customers transfer data and collaborate on projects, tapped into the newly combined ANX/ENX network right away, said James Jarosz, a Trubiquity consultant.
Trubiquity was planning to set up a data-exchange pipeline for a North American parts supplier that wanted to connect with a European customer, Jarosz said.
The new ANX/ENX network proved the right vehicle to make that connection rather than having to create a link internally, he said.
"So far, it's worked very well," Jarosz said.
The two exchanges have operated on parallel tracks since their creation by the auto companies around 2000. ANX was incubated by the Automotive Industry Action Group, then sold in 2006 to a private equity fund, One Equity Partners, which manages investments for JPMorgan Chase & Co.
ENX is owned by a consortium of French and German auto companies, Oly said. He said the exchange offers its participants an option of 35 independent service providers to carry the data over the network.
