M&I Data Services said it has selected Transaction Network Services Inc. of Reston, Va., to provide dial-up communications links to automated teller machines and point of sale devices.

On behalf of its bank data processing customers, M&I, a Marshall & Ilsley Corp. subsidiary, processes more than 40 million dial-up and dedicated-line transactions a month.

Transaction Network Services' "transport" capability "will significantly enhance telecommunications options, quality of services, and cost- competitiveness for our customers," said Frank D'Angelo, vice president and general manager of M&I Data's EFT services division.

"We evaluated several vendors and selected TNS for its breadth of service, reputation in the industry, understanding of the importance of the delivery of electronic funds transfer transactions, and ability to offer a turnkey solution," Mr. D'Angelo said.
