Regarding only the technical aspects and not the availability of B-ISDN switches, one such document is, and here I will attempt to reproduce its cover sheet: COMMITTEE T1 - TELECOMMUNICATIONS STANDARDS CONTRIBUTION DOCUMENT NUMBER: T1Q1.3/90-001R2 DATE: JANUARY 18, 1991 STANDARDS PROJECT: Specification and Allocation of Performance for ISDN (T1Q1-10) SUBJECT: 1990 B-ISDN Recommendations ORIGINATOR: ISDN Experts of Study Group XVIII KEY WORDS: Broadband ISDN (B-ISDN), 1990 Recommendations, CCITT, Accelerated Procedures DISTRIBUTION: T1Q1.3 Working Group Abstract: This contribution, an update of T1Q1.3/90-001R1, provides copies of 13 Broadband ISDN (B-ISDN) Recommendations, which Study Group XVIII unanimously approved at its December 1990 meeting for invocation of Resolution 2 (accelerated approval) procedures. The December 1990 version of the B-ISDN Recommendations made only minor editorial changes to the versions approved by WP XVIII/8 at its June 1990 meeting in COM XVIII-R 34-E. The attached copies of COM XVIII-R 34-E have been updated to reflect the changes reported in Temporary Document 9/XVIII, "1990 B-ISDN Recommendations - Proposed Editorial Amendments," by the Chairman of WP XVIII/8. A report of the December 1990 meeting of Study Group XVIII is provided in T1Q1.3/91-001. The B-ISDN Recommendations provide a stable basis for the development of related B-ISDN performance Recommendations. Copies of the ISDN performance Recommendations from the December 1990 meeting of Working Party XVIII/6 are provided in T1Q1.3/91-002. Obviously, this abstract is intended for internal use, but it indicates the nature of the activity going on concerning B-ISDN at this time. One way to get more information or this particular document is to join the committee(!) Keith E.
