The BEM will also provide you with the a WBSA Questionnaire and other materials as they work with you through the entire onboarding process.

Terms and Conditions

You may order new service subject to loop qualification and availability or convert existing CenturyLink retail end-users to the WBSA offering.

Tier 1 Technical support to include interfacing with our Repair organization and any other peripherals will remain your sole responsibility. Your end-users cannot contact Repair directly.


Service is offered only to location(s) qualified by CenturyLink Loop qualification procedures. Some lines may not qualify for the service even if initial tests qualified such lines. Speed and availability of service are not guaranteed and may be limited by a variety of factors including but not limited to the physical condition of the line and wiring at the service location, copper line qualifications, computer performance/configuration, and network/Internet congestion.

Loop Qualification

Loop Qualification by service address or Working Telephone Number (WTN) is performed during the ordering of service using the CenturyLink IMA and EASE Ordering Portals, or by using Loop Qualification tools in Control Center.

When using the CenturyLink Portals to qualify by WTN, the account must be posted to CenturyLink billing system. When submitting a Local Service Request (LSR), the TNS field must be populated with either a reserve TN or a value of N (depending on IMA or EASE). CenturyLink will provide a data TN upon Firm Order Confirmation (FOC)). When the Loop Qualification response is ‘Out of Capacity’, do not submit a request for new standalone broadband service

Loop qualification will qualify addresses and WTNs for CenturyLink Broadband and will return the highest speed available. The loop qualification response will reflect optional service offerings.

Loop Qualification using IMA (Western Markets)

Loop Qualification Provisional Response

A 'Provisional' response to a Loop Qualification request means that broadband may be available contingent upon certain network activity.

To authorize CenturyLink to attempt to provision broadband on a provisionally qualified WTN or address, populate the SCA field on your Local Service Request (LSR) with 'Y'. This action authorizes CenturyLink to perform a UDC removal or line move, at no additional charge, to allow installation of the broadband service. If a line move or UDC removal is not possible, CenturyLink will send you a jeopardy notice for the LSR.

Note that line moves and UDC removal are not available on N & T orders, C orders adding a new line simultaneously with broadband or on Standalone service.

Bulk Loop Qualification Process

Bulk Loop Qualifications are performed by you using Control Center for all legacy CenturyLink regions. This tool can perform loop qualification either by service address or telephone number (TN). The output files will return the serving wire center and region identifier by location to direct you to the proper IMA and EASE ordering portals.

For specific Bulk Loop Qualification processes within Control Center, see the following Control Center Bulk Loop Qualification link.

For general Control Center help: Control Center Overview

Internet Access

In all instances, CenturyLink will be the Internet Service Provider (ISP) and does not include email or premium ISP features.

Static IP

Static IP addresses are available only when ordering service for Business locations.

New WBSA service is initially set up with dynamic IPs. If the customer wants to order Static IPs, here are the steps:

Note: Static IP addresses are provisioned differently depending on the underlying network configuration. Please see the review the information found in this link to explain the provisioning process, Static IP Processes

Use Policies

You and your end users are subject to the CenturyLink™ Broadband agreements and policies. Please review the links below for specific details.

Provisioning and Installation

If CenturyLink determines the request cannot be provisioned after a FOC has been issued, CenturyLink will send you a jeopardy notice. The jeopardy notification will provide you with information on how to proceed. The jeopardy process is described in the Provisioning and Installation Overview.

Upon receipt of an accurate and complete LSR including authorization of a line move or UDC removal or grooming, you will receive a Firm Order Confirmation (FOC) based on the standard interval found in the SIG. If at any time after you receive the FOC, and prior to the scheduled due date, CenturyLink determines that a line move or UDC removal is required, CenturyLink will apply the line move or UDC removal interval and will re-FOC your LSR reflecting the new scheduled due date. The interval will begin on the date CenturyLink determines that a line move or UDC removal is necessary and a SUP is not required.

Maintenance and Repair

General maintenance and repair activities are described in the Maintenance and Repair Overview.

Charges apply for certain maintenance, trouble isolation, and support services and if a technician is dispatched. Charges may be per technician, may vary depending on when services are performed (e.g., time of day and weekday, holiday or weekend), and may include a minimum charge regardless of the actual number of hours worked. CenturyLink will notify you of any applicable charges in advance of you incurring such charges. If you report trouble, you must pay maintenance of service charge if the trouble is not found in CenturyLink facilities or CenturyLink equipment or is found in customer equipment/systems or Equipment. A dispatch charge also applies if: (A) Customer requests a service date change but fails to notify CenturyLink before the service date and CenturyLink technician is dispatched on the service date (will have to pay dispatch charge and CenturyLink will change the service date) or (B) CenturyLink technician dispatched for maintenance of service and no trouble is found in CenturyLink facilities (applies each time this happens).
