Facility Codes:
CLFI Codes

Common Language Facility Codes (CLFI Codes) provide you with a stable naming scheme for describing cable, fiber, radio, analog- and digital-carrier transmission facilities. These unique codes improve communications within and among companies, and are particularly useful in designing layouts and completing work orders.

CLFI codes include data elements that identify a facility's designation and type as well as the channel or pair number. They also incorporate CLLI codes to indicate a facility's end locations.

While each Common Language Product has been designed to work independently of the others, customers typically benefit most from the integrated solutions offered by our full suite of products and services.
