The Interconnect Mediated Access (IMA) User's Guide together with the Loop Qualification Raw Loop Data and CLEC Job Aid detail the information applicable to pre-ordering functions.

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

  • Validate address
  • Check facility availability
  • Validate Connecting Facility Assignment (CFA)
  • Review Customer Service Record (CSR)
  • Loop Qualification - Query Unbundled Loop
