Approved American National Standard
ANSI/VITA 46.10
Rear Transition Module for VPX
Abstract
Define a rear transition module (RTM) for VPX applications.
Approved Dec 2009
American National Standards Institute, Inc.
American
National
Standard
Approval of an American National Standard requires verification by ANSI that
the requirements for due process, consensus, and other criteria for approval have
been met by the standards developer.
Consensus is established when, in the judgment of the ANSI Board of Standards
Review, substantial agreement has been reached by directly and materially
affected interests. Substantial agreement means much more than a simple
majority, but not necessarily unanimity. Consensus requires that all views and
objections be considered, and that a concerted effort be made toward their
resolution.
The use of American National Standards is completely voluntary; their
existence does not in any respect preclude anyone, whether he has approved the
standards or not, from manufacturing, marketing, purchasing, or using products,
processes, or procedures not conforming to the standards.
The American National Standards Institute does not develop standards and will
in no circumstances give an interpretation of any American National Standard.
Moreover, no person shall have the right or authority to issue an interpretation
of an American National Standard in the name of the American National
Standard Institute. Requests for interpretations should be addressed to the
secretariat or sponsor whose name appears on the title page of this standard.
CAUTION NOTICE: This American National Standard may be revised or
withdrawn at any time. The procedures of the American National Standards
Institute require that action be taken periodically to reaffirm, revise, or withdraw
this standard. Purchases of American National Standards may receive current
information on all standard by calling or writing the American National
Standards Institute.
NOTE – The user’s attention is called to the possibility that compliance with this standard may require use of an
invention covered by patent rights.
By publication of this standard, no position is taken with respect to the validity of this claim or of any patent rights in
connection therewith. The patent holder has, however, filed a statement of willingness to grant a license under these
rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license. Details
may be obtained from the standards developer.
