HOW IT WORKS 
——
CenturyLink Domestic Private Line Service provides a fixed capacity of bandwidth for transport of your digital communications traffic, utilizing and conforming to SONET standards that originate and terminate a physical connection at a CenturyLink-specified demarcation point located in the CenturyLink POP. The service extends to and includes the equipment maintained by CenturyLink that is necessary to connect the service to the customer's interconnection facilities at the CenturyLink-specified network interface points. Interconnection, collocation, and/or local access services are not included as part of the Domestic Private Line service, but may be ordered in conjunction, either through CenturyLink or other telecommunications providers. Digital Private Line service is available at DS-0 (64 Kbps), fractional DS-1 (128 Kbps and up), DS-1 (1.544 Mbps), DS-3 (45 Mbps), and OC-N (155 Mbps and up). Digital Private Line services utilize digital local loops that provide nearly 100 percent end-to-end network availability. CenturyLink DS-1 service can also be configured as clear channel or channelized, and is compatible with virtually all DS-1 systems in use today.
