Pre-Ordering

General pre-ordering activities are described in the Pre-Ordering Overview. Requirements for pre-ordering are described in the Local Service Ordering Guidelines (LSOG)

  • Is using the circuit for local traffic.
  • Is ordering a circuit in an impaired Wire Center as filed by CenturyLink QC.
  • Is ordering a circuit that does not exceed the cap in an impaired Wire Center as filed by CenturyLink QC.
  • Is not accessing an unbundled network element for the provision of mobile wireless services or interexchange services.

The Certification of Remand Order Criteria High Capacity Unbundled Transport, Unbundled Loop, and Combinations form is kept on file at CenturyLink subsequent to submission to the Account Team / Sales Executives and Service Managers.

Loop Qualification

The Interconnect Mediated Access (IMA) User's Guide specifically details the information applicable to preordering functions.

CenturyLink strongly recommends use of pre-ordering functionality to assist in achieving increased service request flowthrough and accuracy that will result in reduced order rejects.

The following activities may need to be performed by you in preparation for the issuance of the service request:

  • Validate address
  • Validate Connecting Facilities Assignment (CFA)
  • Review Customer Service Record (CSR)
  • Check facility availability
  • Query Fiber Data Reports

These activities will enable you to verify the type of facility and the loop make-up of the Unbundled Local Loop, which will assist you in identifying the appropriate service intervals, described in the Service Interval Guide (SIG).

More information can be found on these activities in the Loop Qualification and Raw Loop Data - CLEC Job Aid.
