DDS is a core private line solution providing full duplex, four-wire transmission of synchronous serial data over a dedicated point-to-point or multi-point circuit between two end users or between an end user and another carrier. CenturyLink provides timing for this service through facilities to the end user on the received bit stream. DDS is only available between locations that can be connected through compatible digital facilities.
The CenturyLink network covers the entire continental United States and has one of the largest fiber footprints. Internationally, we provide coverage to hundreds of destinations.
