Overview

An ISDN Ordering Code (IOC) is intended to provide customers with an easy to communicate term with which to order a specific set of ISDN services and features from their local service provider. An IOC refers to and is defined by a specific set of National ISDN services and features. An IOC is associated with specific equipment or application(s), as well as the specific set of technical switch translations necessary to provide the appropriate ISDN interface to customers. When customers provide an IOC to the ISDN service provider, it is intended that service may be quickly and accurately provisioned, as the IOC provides in advance the technical switch translations for the services and features needed for the identified equipment/application.

IOC's are used by both Resale and UNE-Platform Services.
