Chapter 1 - Introduction
CHAPTER 1 - INTRODUCTION
The AT command set is one of the main interfaces for the modem to interact with an external application layer. CDMA AT commands are defined in TIA/EIA/IS707.3. However, as the wireless applications increase, TIA/EIA/IS707.3 is not sufficient. In addition, a lot of GSM applications already exist and GSM customers would like to maintain the same interface in order to make no or minimum changes to the applications to be used with CDMA modem. To meet the all these needs, CDMA AT command set is designed to cover:
1) IS707.3 AT commands;
2) GSM 07.07 when applicable;
3) GSM 07.05 when applicable,
4) ITU-T v25 when applicable;
5) Proprietary AT set;
6) Customer specific AT commands;
7) Qualcomm defined AT commands.
Please note that in several instances, the GSM 7.07 and 7.05 specifications could not be followed because of fundamental differences between CDMA and GSM call processing behaviors. In these cases, minimal changes were made to the GSM-related commands.
Scope of This Document
This document describes the CDMA AT command, its syntax, its responses, and result codes. It serves as the reference for wireless application development based on the CDMA modem and for its integration and testing. The intended audience is expected to be familiar with CDMA data services protocol and AT modem commands.
This document is also intended for use in the North American market. SIM/R-UIM and its related AT commands are not documented here.

General Indicator +WIND
Description: This is a general mechanism to send unsolicited non-standardized indications to the
application. The identified unsolicited non-standardized indications are:
• Indication during mobile originated call setup that the calling party is ringing.
• Indication of the availability of the product to receive AT commands after boot.
The +WIND is overloaded with two functionalities:
1) posts non-standardized indications and
2) allows the user to specify indication level. For each of these indications, a “bit flow” has to be indicated.
Values: <IndLevel>
1 (bit-0): R-UIM Presence 2 (bit-1): Reserved 4 (bit-2): Reserved 8 (bit-3): Indication that the product is ready to process all AT commands 16 (bit-4): Reserved 32 (bit-5): Reserved 64 (bit-6): Network service available indication 128 (bit-7): Network lost indication 256 (bit-8): Reserved 512 (bit-9): Reserved 1024 (bit-10): Corrupted RF calibration values (checksum mismatch)
Note 1: If <IndLevel> is equal to 0, no unsolicited “+WIND: <IndNb>” will occur.
Note 2: If <IndLevel> bit 10 is set, the modem will transition to OFFLINE mode.
A combination (addition of the values) is used to allow more than one indication flow. 0 < d Level ¡Ü 2047 For example: 128 (network lost indication) + 64 (network service available indication) = 192.
The response is OK if the values are in the previous range.
The unsolicited response will then be: +WIND : <event>
Example Result +WIND:8 Note: General indication that AT commands are ready to be accepted
The supported events are:
<event>
0: R-UIM not present 1: R-UIM present 2: Reserved 4: Reserved 16: Reserved 32: Reserved 64: The network service is available for an emergency call. 128: The network is lost. 256: Reserved 512: Reserved 1024: Corrupted RF calibration values (checksum mismatch)
