LOA-CFA (also called CFA-LOA) is an abbreviation of two related terms. These terms are: Letter Of Authority and Customer Facility Assignment. An LOA-CFA typically refers to the document issued by a Telecommunications carrier to another carrier giving them permission to use a specified facility assignment for interconnection.
The LOA-CFA document typically includes who issued the document, who it is provided to, and what specific facilities have been reserved for use by the new carrier. The document may include legal conditions that both parties agree to concerning cancellation, reciprocation of information or other issues.
A series of facilities connected together create a circuit, and may require a DLR to determine the end to end telecommunications engineering.
