Information Technology Announcements from ANSI Standards Action
Vol. 22, No. 2 January 25, 1991
Ordering information for particular documents and general information
appears at the end of this digest.
Call for Comments (public review), Comment Deadline March 26, 1991.
------------------------------
BUS
BSR/IEEE C37.97, Guide for Protective Relay Applications to Power
Systems Buses (new standard)
Assists in the effeective application of relays for protection of
power system electrical buses. The bus protection described refers
only to protection at the buslocation, independent of equipment at
remote locations. Common bus arrangements and some special
arrangements used in the U.S. are covered; not all bus protection
systems or all possibly arrangements are included. This standard was
administratively withdrawn by ANSI on April 9, 1990, as is being
resubmitted.

Comments (with copy to BSR) to: Linda A. Dame, IEEE
------------------------------
BUS
BSR/IEEE 802.6, Distributed Queue Dual Bus (MAN) (new standard)
Defines a high-speed shared medium access protocol for use over a
dual, counter flowing, unidirectional bus subnetwork of a Metropolitan
Area Network (MAN). Specifies the Physcial Layer and DQDB Layer
required to support Logical Link Control (LLC) sublayer by a
connectioness Medium Access Control (MAC) sublayer service in a manner
consistent with other IEEE 802 Local Area Networks. Also specifies
additional DQDB Layer functions that will support isochronous service
users and connection-oriented data service users.
Single copy price: $38.50
See IEEE order and comment information above.
------------------------------
BUS
BSR/IEEE 1118, Microcontroller System Serial Control Bus (new standard)
Defines an interconnect bus for (but not limited to) microcontrollers
and devices with limited reprogrammability. This bus provides a multi-
drop bit-serial communication protocol that will allow the
interconnection of distributed independently manufactured devices. The
protocol is optimized for instrumentation, distributed data acquisition
systems, control devices, and test and measurement.
Single copy price: $51.72
See IEEE order and comment information above.
------------------------------
INFORMATION SYSTEMS
BSR/IEEE 754-1985, Binary Floating Arithmetic (reaffirmation of
ANSI/IEEE 754-1985)
Enables implementation of a floating-point system conforming to this
standard to be realized entirely in software, entirely in hardware, or
in any combination of software and hardware. It is the environment the
programmer or user of the system sees that confirms or fails to conform
to this standard. Hardware components tht require software support to
conform shall not be said to conform apart from such software.

------------------------------
LANGUAGES, PROGRAMMING
BSR/IEEE 1178, Scheme Programming Language (new standard)
Specifies the representation of Scheme programs, their syntax, the
semantic rules for interpreting them, and the representation of data to
be input or output by them. Does not specify the mechanisms by which
Scheme programs are transferred to and from system memory and placed
into execution, or the size or complexity of a program and its data
that will exceed the capacity of a particular implementation.

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.
