COMPUTER GRAPHICS
Note: the following is a national adoption of an international
standard.
BSR/ISO 9593-1, Information Processing Systems--Computer Graphics--
Programmer's Hierarchical Interactive Graphics System (PHIGS) Language
Bindings--Part 1: FORTRAN (revision and redesignation of ANSI
X3.144.1-1988).
Addresses the fact that the Programmer's Hierarchical Interactive
Graphics System (PHIGS) is specified in a language-independent manner
and needs to be embedded in language-dependent layers (language
bindings) for use with particular programming languages. The purpose
of this document is to define a standard binding from the FORTRAN
computer programming language.

TELECOMMUNICATIONS
BSR T1.409, Interface Between Carriers and Customer Installations--
Analog Voicegrade Special Access Lines using E&M Signaling (new
standard).
Provides signaling requirements for the analog voicegrade interface
between telecommunication carriers and customer installations when E&M
signalling is used across the interface. The requirements are intended
to assist carriers, manufacturers, and users of products used with
telecommunication networks to understand the parameters of the existing
networks.

BSR T1.605, Integrated Services Digital Network ISDN--Basic Access
Interface for S and T Reference Points (Layer 1 Specification)
(revision of ANSI T1.605- 1989).
Presents the electrical characteristics of the Integrated Services
Digital Network (ISDN) Basic Access signals appearing at the S and T
reference points. It also describes the physical interface between the
TE and an NT. This interface standard was written to provide the
minimal set of requirements to provide for satisfactory transmission
between a TE and an NT. The standard conforms (except as noted in
Appendix L) with International Telegraph and Telephone Consultative
Committee (CCITT) Recommendation I.430. However, it specifies
individual departures from CCITT Recommendation I.430 that reflect the
domestic environment of the United States.
BSR T1.615, Digital Subscriber Signalling System No. 1 (DSS1)--Layer 3
Overview (new standard)
Provides an overview of DSS1 Layer 3 functions an protocols, as well
as a list of the standards in which individual aspects of the DSS1
Layer 3 suite are defined. The Digital Subscriber Signalling System
No. 1 (DSS1) is a suite of protocols which provides the means for users
to invoke the full range of services and capabilities available from
the Integrated Services Digital Network (ISDN). The structure of DSS1
is consistent with the seven-layer model described in CCITT
Recommendation I.320. The complete suite of Layer 3 DSS1 protocols
encompasses a set of several standards, each one addressing its own
aspect of the suite.

Ground rules and boilerplate:
The information above is provided for the information and use of ACM
members.
The information is obtained from the issue of ANSI Standards Action
designated. The intent is to include announcements that are likely to
be of interest to the ACM membership. For a given draft standard or
other reference, all information provided in Standards Action is given.
This listing will include, insofar as possible, relevant solicitations
of comments (announcements of availability for public review). As time
and resources permit, it will also include announcements of newly
published Standards, final action on Standards, and other relevant
announcements including, eventually, notification of relevant new
project initiations.
While a reasonable effort is applied to ensure the accuracy of the
listings, omission of important material is possible and typographic
errors are likely, so appropriate caution should be used.
The ANSI public comment process solicits comments "to ensure that the
views of all interested parties have been given full consideration."
If you choose to order and review a draft document, your response
should "specify whether you approve of disapprove of the proposal as an
American National Standard. If you provide technical comments with
your approval, indicate whether approval is contingent upon considering
them for inclusion (1) in the current proposal or (2) in future
revisions of the current proposal. If you disapprove, give your
reasons." Draft documents are not, in general, available from the
source indicated after the closing date for comments. Comments should
be addressed to the person or organization, with copies to the ANSI
Board of Standards Review (BSR), 1430 Broadway, NY, NY 10018.
Comments on draft ISO, IEC, or ISO/IEC Draft International Standards
should be addressed, in the USA, to Gary W. Kushnier, Vice President,
Standards Technology, at ANSI headquarters (address above). These
comments should be made considerably before the date given if you
expect them to have any impact. Outside the US, comments on these
documents should be addressed to the relevant national ISO Member Body.
ANSI Standards may be obtained from the ANSI Sales Department, 1430
Broadway, NY, NY 10018.
ISO and IEC drafts and final Standards may be obtained from the
International Sales Department, ANSI, 1430 Broadway, NY, NY 10018.
Place separate orders for ISO and IEC Draft Standards. Order BSR
proposals and newly published ANSI and ISO and IEC Standards
separately. Readers outside the US are likely to be able to obtain ISO
and IEC materials more efficiently through their own ISO Member Bodies.
In only extremely rare cases (which will be noted if known) are these
documents available for electronic distribution.
