NC codes identify the technical details of channels provided by an exchange carrier, or other service provider, from the point of termination (POT) at another carrier's point of presence (POP) to the central office.

NCI codes identify interface elements such as physical conductors, protocol, impedance, protocol options, and transmission level points that reflect physical and electrical characteristics located at a POT at the switch or customer location.
