Introduction
This document describes standard and proprietary AT
commands that are available for users of UMTS AirCard
modems and Mini Card embedded modules.
The standard 3GPP AT commands for UMTS devices are
described in two standards documents available from the
3GPP (3rd Generation Partnership Project) web site,
www.3gpp.org:
• TS 27.007 AT command set for User Equipment (UE)
• TS 27.005 Use of Data Terminal Equipment ‐‐ Data Circuit
terminating Equipment (DTE‐DCE) interface for Short Message
Service (SMS) and Cell Broadcast Service (BSE)
The proprietary AT commands are supplemental to the
standard AT commands.
For normal operation of the modem, consult the GSM AT
Command Reference (document number 2130213). You may also
want to consult the other documents available in the AC8xx/
MC87xx Development Kit or on our Internet site at
www.sierrawireless.com
Note: Some standard 3GPP commands are NOT supported, or are
partially supported. These commands are identified in
GSM / WCDMA AT Commands,
Note: When designing applications that use these AT commands, use
®
Watcher (and other Sierra Wireless applications) as functionality
templates to ensure proper use of command groups. For questions or
concerns relating to command implementation, please contact your
Sierra Wireless account representative.
