History Log

Product Description

CenturyLink Broadband provides flexibility to connect telecommuters, campus users and business partners to your business at various speeds-and CenturyLink Broadband Host service offers the aggregation point for all DSL user traffic pointed to your business.

These two categories correspond to the spoke and hub network of the DSL service:

  • CenturyLink Broadband subscribers are the "spoke" network connections.
  • CenturyLink Broadband Host is the "hub".

Each of the "spoke" connections must be associated with a "hub" or a CenturyLink Broadband Host. CenturyLink Broadband Host service allows you to aggregate data streams from many CenturyLink Broadband Subscribers onto a single high-speed data connection via CenturyLink asynchronous transfer mode (ATM) cell relay backbone. CenturyLink Broadband Host and subscribers are connected via virtual channel connections (VCC).

To become a CenturyLink Broadband Host and enable CenturyLink Broadband end-user subscribers to select/use your Internet service provider (ISP) services, you will need the following services in each local access transport area (LATA) you wish to serve as a CenturyLink Broadband Host:

  • ATM access link or private line connection to a CenturyLink ATM switch.
  • Broadband host bandwidth.
  • Host termination router.
  • Gateway to the Internet (if an ISP).


CenturyLink Broadband Host service is offered under the terms and conditions of a commercial agreement. For additional information, contact your Account Team, Sales Executive, or Service Manager for more information.

When a CenturyLink Broadband Host customer is located in a wire center other than an ATM switch wire center, or a broadband host service point, then a Private Line DS-1 or DS-3 would be ordered using the standard DS-1/DS-3 ordering process. The Private Line is ordered as a dangling service to the nearest central office that has either the ATM switch or service point. Private Line transport mileage/channel charges will be billed for the Private Line.

Actual DSL speeds vary depending on service location, phone line qualifications, computer performance/configuration, network/Internet congestion and other factors. Uninterrupted or error-free service is not guaranteed.

Terms and Conditions

The minimum service period for CenturyLink Broadband Host service is 12 months from the date of service. If by the end of the term of the agreement a new agreement is not entered into, the service will continue under the initial agreement on a month-to-month basis at month-to-month rates.

Month-to-month broadband host service has a minimum service period of one month, only after the initial one-year fixed-period plan has expired.
