Glossary

Defines the NI-2 set of features and functional capabilities to be provided in the National ISDN offering, composed of those directly related to serving user applications, as well as operations support and billing capabilities aimed at service providers. Identification of the required capabilities is derived from a variety of sources, with Bellcore generic requirements, in most cases, providing the norm for defining those capabilities. Delivery of NI-2 capabilities is planned to start in the second half of 1993. Provides revisions to SR-NWT-002120, National ISDN-2 (NI-2) which, with the exception of the correction of a typographical omission, apply only to capabilities associated with a Primary Rate Interface.
