History Log

Product Description

High Speed Internet´┐Ż provides flexibility to connect telecommuters, campus users and business partners to your business at various speeds-and High Speed Internet 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:

  • High Speed Internet Subscribers are the "spoke" network connections.
  • High Speed Internet Host is the "hub"

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

To become a High Speed Internet Host and enable High Speed Internet 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 High Speed Internet Host:

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


No new High Speed Internet Host orders or High Speed Internet Host locations will be available as a Title 2 Tariff offering as of January 28, 2006. Any new request will be ordered under the terms and conditions of a Commercial agreement. For additional information, contact your Account Team, Sales Executive, or Service Manager for more information.

Your serving CenturyLink wire center must be ATM disclosed. You may verify services at:

When a High Speed Internet Host customer is located in a wire center other than an ATM switch wire center, or a DSL Host service point, then a Private Line DS-1 or DS-3 would be ordered using the normal 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 DSL Host Service under a fixed period service plan is 12 months.

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

A signed High Speed Internet Host contract is required before DSL Host service is provisioned. When ordering High Speed Internet Host via an ASR the ASR number may be used in lieu of the contract number. If a Private Line or ATM OAL (Optical Access Link) are used for transport they must be ordered on a separate ASR.

A High Speed Internet Host access link is a CenturyLink provided physical connection between a disclosed ATM central office or a DSL Host service point, and the High Speed Internet Host customer premises.

The High Speed Internet Host access link transmits data from the customer's host or central location to the Company ATM network.

High Speed Internet Host access links are available as follows:

  • 1.544 Mbps clear channel DS-1 private line transport (PLT) channel termination. A DSL Host port & bandwidth and High Speed Internet Host central office connecting channel (COCC)
  • 45 Mbps DS-3 PLT channel termination. A DSL Host or ATM 45Mbps port and High Speed Internet Host COCC
  • 45 Mbps, OC3 or OC12 ATM cell relay OAL for customers within the optical reach limits of the ATM serving wire center. A DSL Host or ATM port applies in addition to the access link.

DSL Host Port

A DSL Host port is a port on the ATM switching system at the serving wire center or the DSL Host service point.

The types of ports applicable to DSL Host Service are:

  • 1.544 Mbps DSL Host port
  • 45 Mbps DSL Host or ATM port

A 45 Mbps DSL Host or ATM port is capable of terminating DSL Host bandwidth in 3 Mbps increments from 3 Mbps through 45 Mbps. You may choose to use an ATM port if you do not require the 45Mbps DSL Host port.
