The company hopes the extended support will make it easier for providers to offer virtual private network (VPN) services and other managed services.
AT&T also will provide network management and monitoring capabilities to ISPs and cable companies, permitting automated trouble reporting and trouble shooting, as well as performance reports and capacity management.
The reporting and management functions are a prerequisite for service providers to deploy VPN services, said Kate Rankin, an AT&T spokeswoman. "We're hoping this will get more cable companies and ISPs to migrate to our backbone," she said.
The new offering will, potentially, improve cable operators' ability to offer business services, moving beyond consumer broadband Internet access. It also is another step in its plan to counter the effect of the end of its Concert Communications international joint venture with British Telecom.
AT&T offers its fully managed IP VPN service in 54 countries, but is only beginning to support MPLS services internationally. AT&T plans to have 102 nodes with MPLS capability deployed in 88 cities throughout the world by the end of the year.
