1 1: About This Guide • • • • Introduction Result codes References Current firmware versions • Document structure • Conventions Introduction This document describes proprietary, password‐protected AT commands available for the MC87xx embedded modem. These commands are supplemental to the standard AT commands for GSM devices defined by the 3GPP (The 3rd Generation Partnership Project) and are intended for use by OEMs.
MC87xx Extended AT Command Reference The password assigned to AT!ENTERCND is unique to each carrier and is configured onto the modem during manufacture. If you do not know your password, contact your Sierra Wireless Account Manager. Command timing Some commands require time to process before additional commands are entered. For example, the modem will return “OK” when it receives AT!DAFTMACT. If AT!DASBAND is received too soon after this, the modem will return an error.
About This Guide Current firmware versions Versions Note: Revisions using letters are to be considered drafts and are subject to change before final release. This document is revised periodically as new firmware versions are released. This edition is: Document Rev 2.9 9 October 2008 Each command listed in this guide includes a list of supporting MC87xx modules.
MC87xx Extended AT Command Reference Note: The ‘Supporting Mini Cards’ column indicates which Mini Card models support each command. If an entry is marked with an asterisk (*), a firmware upgrade may be required. See the detailed command entry for details. This chapter describes commands used to enable access to password‐protected AT commands and to set the AT command password.

7 7: Voice Commands • • • • Introduction Audio profiles Command summary Command reference Introduction The MC8775V, MC8785V, MC8790V, MC8791V, and MC8792V modems have built‐in audio support that allow the modems to be used as mobile phones. The modems all support a single analog audio interface that can be used for handset‐style applications or headset applica‐ tions, and a PCM digital audio interface.
MC87xx Extended AT Command Reference The embedded module can serve as an integral component of a more complex audio system, such as a PDA with a separate codec interfacing with the main processor. In this case, the interface between the modem and PDA codec can be as simple as line‐level audio with no transducer considerations.
Voice Commands The MC87xx modem supports six or eight audio profiles, depending on the module type: • 0—Handset • 1—Headset • 2—Car kit • 3—Speaker phone • 4—Auxiliary • 5—TTY (TeleTYpe—a device that allows speech and hearing‐impaired people to use a phone) • (MC8785V / MC8790V / MC8791V / MC8792V only) 6—Auxiliary external PCM (128 kHz clock) • (MC8785V / MC8790V / MC8791V / MC8792V only) 7—Primary external PCM (2 MHz clock) AT commands that are used to change the audio configuration have
