Chapter 1 – Introduction
Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide 9
This CDMA AT command set is designed to cover the following:
● IS707.3 AT commands
● GSM 07.07 when applicable
● GSM 07.05 when applicable
● ITU-T v25 when applicable
● Proprietary AT set
● Customer specific AT commands
● Qualcomm defined AT commands
Note that the GSM 7.07 and 7.05 specifications could not be followed in some instances because of differences
between CDMA and GSM call processing behaviors. In these cases, minimal changes were made to GSM-related
commands.
Document Scope
This document describes CDMA AT commands, their syntax, 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.
