The Contribution shall disclose any known limitations on the Source's rights to license as herein provided. When a Contribution is submitted by the Source(s) to assist the formulating groups of 3GPP2 or any of its Organizational Partners, it is proposed to the Committee as a basis for discussion and is not to be construed as a binding proposal on the Source(s). The Source(s) specifically reserve(s) the right to amend or modify the material contained in the Contribution.

With respect to the Software necessary for the practice of any or all Normative portions of the Enhanced Variable Rate Codec (EVRC) as it exists on the date of submittal of this form, should the EVRC be approved as a Specification or Report by 3GPP2, or as a transposed Standard by any of the 3GPP2's Organizational Partners, the Source(s) state(s) that a worldwide license to reproduce, use and distribute the Software, the license rights to which are held by the Source(s), will be made available to applicants under terms and conditions that are reasonable and non-discriminatory, which may include monetary compensation, and only to the extent necessary for the practice of any or all of the Normative portions of the EVRC or the field of use of practice of the EVRC Specification, Report, or Standard. The statement contained above is irrevocable and shall be binding upon the Source(s). In the event the rights of the Source(s) in and to copyright or copyright license rights subject to such commitment are assigned or transferred, the Source(s) shall notify the assignee or transferee of the existence of such commitments. *******************************************************************/ /*======================================================================*/ /* Enhanced Variable Rate Codec - Bit-Exact C Specification */ /* Copyright (C) 1997-1998 Telecommunications Industry Association. */ /* All rights reserved. */ /*----------------------------------------------------------------------*/ /* Note: Reproduction and use of this software for the design and */ /* development of North American Wideband CDMA Digital */ /* Cellular Telephony Standards is authorized by the TIA. */ /* The TIA does not authorize the use of this software for any */ /* other purpose. */ /* */ /* The availability of this software does not provide any license */ /* by implication, estoppel, or otherwise under any patent rights */ /* of TIA member companies or others covering any use of the */ /* contents herein. */ /* */ /* Any copies of this software or derivative works must include */ /* this and all other proprietary notices. */ /*======================================================================*/ /*********************************************************************** * * FILE : mathevrc.h * * PURPOSE: * * Modified ETSI basic operations.
