Reliability in the Backbone – and More

AT&T is a leading Tier 1 Internet Service Provider with a high performing OC48/OC192 IP Backbone. As the market leader in high-capacity OCX solutions, AT&T can offer you worldclass reliability when your communications race to the Internet.

The backbone’s multiple-ring design provides alternate routes between backbone nodes for enhanced service reliability. All routers are deployed in a redundant configuration,

With fully-redundant power supplies and route switch processors, they’re equipped with battery backup equipment and emergency generators. In fact, the architecture enables immediate rerouting around outages for almost instantaneous service restoration.

Reliability doesn’t stop there. The Managed Internet Service Access Redundancy Options optimize the performance of multiple, dedicated Internet circuits while eliminating single points of failure in the access circuits and routers on your site and in the AT&T IP Backbone node where your connection is terminated. The result is even higher performance with greater levels of reliability.
