Network Channel and
Channel Interface Codes:
Common Language Network Channel and Channel Interface Codes (NC/NCI Codes) provide you with a stable naming scheme for describing network channels, circuit-interface characteristics and associated interface specifications. NC and NCI code sets simplify the provisioning and billing processes and their standard, compact format makes it easy for you to order access services.Downloads:
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.
