Telecommunications provider US LEC is expanding the reach of its Internet Protocol based virtual private network services to four new markets.

The multi-protocol label switching VPN service is now available in Baltimore, New York City, Pittsburgh and Richmond.

“This roll-out continues our strategy of delivering advanced IP-based products and services throughout our 16-state footprint,” said Jeff Blackey, senior vice president of marketing and business development for US LEC (Nasdaq: CLEC). “The addition of IP-based networking to these markets strengthens US LEC’s role as a dominant business communications provider of advanced products and services that customers require to run their businesses more efficiently.”

The service supports voice over Internet Protocol (VoIP) offerings as well as secure networking.

“MPLS VPN allows our customers to continue networking the same applications today and prepare a data network migration path to advanced IP-based services like peer-to-peer applications, Video over IP and Voice over IP,” Blackey said.

The service is already available in several markets, including Charlotte and Atlanta.
