Alternative and diverse routing
Alternative routing provides two different cables from the local exchange to your site, so you can protect against cable failure as your service will be maintained on the alternative route.
Furthermore, with diverse routing, you can protect not only against cable failure but also against local exchange failure as there are two separate routes from two exchanges to your site.
