Abstract: This document represents a snapshot of Integrated Services Digital Network (ISDN) features within the National ISDN Enhancements process. Telcordia and the regional companies working with industry members and with input from the National ISDN Users' Forum (NIUF) have developed a new process for identifying feature enhancements to National ISDN. This document describes the process and presents the NI-Enhancement candidates and identifies their position in the process.

Abstract: This document provides Telcordia view of proposed generic guidelines for terminals that offer Integrated Services Digital Network (ISDN) terminal adapter capabilities on Basic Rate Interfaces (BRIs). ISDN terminal adapters provide the interworking function between conventional analog lines and ISDN lines, allowing analog terminals connected to these adapters the ability to continue to function and operate in an ISDN environment. The generic guidelines in this document will apply only to terminals that offer ISDN terminal capabilities for voice applications. More specifically, this document assumes that the basic R-interface (i.e., between an ISDN terminal and an analog terminal) support a conventional analog telephone access line with Plain Old Telephone Service (POTS) capabilities.

Abstract: This document describes and defines National ISDN-3 (NI-3). This builds upon the work begun in NI-1 and NI-2, as defined SR NWT-001937 and SR NWT-002120, respectively with the intent of furthering the progress towards the goal of Nationa l ISDN. NI-3 is the culmination of an industry effort to realize a marketable and feasible set of features taking into consideration market needs, difficulty of implementation, and ease of use.

Abstract: This Special Report defines the National ISDN-2 (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 suppo rt and billing capabilities aimed at service providers. Identification of the required capabilities is derived from a variety of sources, with Telcordia generic requirements, in most cases, providing the norm for defining those capabilities.

Abstract: A group of Telcordia Technical References (TRs) was published in 1988 giving Telcordia view of proposed generic requirements to provide Telcordia Client Companies (BCCs) with the flexibility to meet changing customer needs as ISDN is introduced. These TRs are referred to as the ISDN Phase 1 TRs. In mid-1990, it became apparent from information supplied by some network switch vendors that full compliance with the Phase 1.1 ISDN feature set was not feasible by the end of 1991. Since that time, Telcordia has been working to identify a marketable and maintainable package based on the ISDN Phase 1.1 TRs that switch vendors can develop in the 1991-1992 time frame. Telcordia has prepared this document to summarize the results of this effort, now known as 1992 Nationwide ISDN. BCCs have indicated their desire to proceed with the introduction of ISDN as the platform for the communication networks of the next century. 1992 Nationwide ISDN is viewed as the platform needed to create an offering for both the large business and mass markets. The mass market as refocused by the BCCs includes small business Centrex and residence customers.
