Forecasting - V72.0

History Log


Forecasting of potential growth is important to interconnection. The availability of inventory is a key component of CenturyLink's Service Delivery process. CenturyLink™ strives to deliver wholesale services to meet your business needs. Through a Joint Forecasting Process, CenturyLink will provide network components in a timely manner to help you develop new solutions for your business.

Your Interconnection Agreement outlines that CenturyLink and Competitive Local Exchange Carriers (CLECs) will work in good faith to define mutually agreed upon Local Interconnection Service (LIS), Wireless Type 2 Interconnection and Collocation forecasts. These forecasts provide information for planning the switch capacity facilities, power, space, and basic space construction, etc. CenturyLink and you will participate in joint planning meetings annually to establish trunk design and provisioning requirement information to assure end-user call completion between networks. Important Note: If you choose to submit forecasts for Unbundled Network Elements (UNEs) to CenturyLink, we will accept them. However, CenturyLink has no obligation to construct facilities for use as UNEs; therefore, these forecasts will be filed for reference only.

If terms and conditions for forecasts are included in your Interconnection Agreement, and those terms differ from those set forth within this Web page, the terms of your Interconnection Agreement will prevail.

General Requirements

LIS/Wireless Type 2

Switch capacity growth requiring the addition of new switching modules may require six months to order and install. To align with the timeframe needed to provide for the requested facilities, including engineering, ordering, installation, and make-ready activities, CenturyLink collects forecasting information about orders that you will submit six to 48 months into the future. To establish trunk design and forecast requirements, CenturyLink and you have the obligation to participate in joint planning meetings at annual intervals (See Schedule below). The forecast shall be for trunking that impacts the switch capacity and facilities of each party.

Typical forecast timelines are discussed in the LIS Trunk Forecast Directions and Wireless Type 2 Directions (shown below under "Forecasting Tools") for growth planning. For capacity growth, CenturyLink utilizes your forecasts to ensure availability of switch and transport capacity. In addition, after the close of the forecast cycle, CenturyLink will advise you, via e-mail, that you can request a copy of your Market Adjusted Forecast. This CenturyLink-adjusted forecast is used in the capital acquisition and build cycle by CenturyLink.

Deposit Process

If, upon review of the CenturyLink-adjusted-forecast, you want to ensure that CenturyLink builds to your higher forecast, a refundable deposit is required. If your Interconnection Agreement does not discuss a forecast deposit, contact your CenturyLink Service Manager to process an amendment. Deposit process terms and conditions may vary by state.

A typical deposit process is as follows:

  1. If your statewide trunk utilization (trunks in-service versus trunks-required) ratio over the past 18 months is less than 50% each month, you must submit a refundable deposit to CenturyLink if you want assurance that CenturyLink will build to your higher forecast.
  2. The deposit will be calculated based on the difference between the higher forecast and the lower forecast.
    1. For an end office (direct trunk) connection, a deposit of $6,500 per DS1 is required.
    2. For a tandem office connection, a deposit of $16,000 per DS1 is required.
  3. If your statewide trunk utilization ratio during the six-month period after submission of the deposit meets or exceeds 50% in any month, the deposit is refunded. If the statewide trunk utilization ratio is less than 50% a pro-rata portion is returned.

Deposits are held in the Billing and Receivable Tracking (BART) billing system.


CenturyLink requests that you submit an annual forecast, updated at the end of each quarter, of your future Collocation requirements. Individual CLEC Interconnection Agreements may differ on specific terms and conditions for forecasting. See your Interconnection Agreement for clarification regarding how to submit forecasts prior to Collocation orders. Your forecast can be exceeded by twenty percent for floor space and power requirements where applicable. The forecast must include, for each CenturyLink premises, the following:

  1. Identification of CenturyLink premises
  2. Floor space requirements, including the number of bays for a cageless Collocation arrangement
  3. Power requirements
  4. Heat dissipation
  5. Type of Collocation (e.g., caged physical, cageless physical, shared Interconnection Distribution Frame (ICDF), virtual, etc)
  6. Entrance facility type
  7. Type and quantity of terminations
  8. Date you expect to submit your collocation application
  9. Send quarterly forecast to rfsmet@centurylink.com

Unbundled Elements

As stated earlier in this document, it is important to note that if you choose to submit forecasts for UNEs to CenturyLink, we will accept them. However, CenturyLink has no obligation to construct facilities for use as UNEs, therefore, these forecasts will be filed for reference only. In order to assist you in developing your forecasts, information is available regarding CenturyLink's existing services by wire center and product type that can be obtained from CenturyLink's Operations Systems Support. CenturyLink provides you a tool, Raw Loop Data Tool that contains information that may be useful in developing your forecasts. Contact your CenturyLink Service Manager for access to this tool.

If you choose to provide your forecast at the Distribution Area (DA) level, download the site for ArcGIS Explorer and User's Guide. In addition to ArcExplorer, you will need the latest updated version of the DA level mapping on CD-ROM. For more information regarding DA Mapping refer to the Pre-Ordering section of Field Connection Point - Cross Connect Collocation.

Because UNE forecasts are not required by CenturyLink, there is no schedule for submitting them.

Existing CLECs may contact their CenturyLink Joint Planning Engineer to submit annual forecasts.

Unforecasted Demand - LIS/Wireless Type 2, Collocation & Unbundled
If you need to adjust a forecast submitted earlier as a result of errors, changes or corrections, you may use an Unforecasted Demand Notification Form at any time between regular forecast submissions.

Accurate forecasts enable timely provisioning although CenturyLink has not changed its practice of readily accepting orders that are not associated with a forecast. CenturyLink's capacity planners will prepare for both planned (they receive both your standard forecast and your adjustment, if any) and unplanned growth.

To access one of the following forms, click on the appropriate form to download the document. Contact your assigned Joint Planning Engineer for assistance in completing the form(s). We will help you specify your needs as requested in the forecasting process. CenturyLink will continue to work with you to refine your forecast as your needs change and as you grow.
