Introduction

1.1. General

The 3GPP TS 27.007 technical specification defines an AT command set for use in controlling devices
that operate on WCDMA networks. This document identifies which of those AT commands are
supported on the CHU628 USB modem module.

The specification document that lists the AT command set, 3GPP TS 27.007 V5.6.0(2005-03), is
available on the 3GPP web site, www.3gpp.org

The table below identifies whether each command is supported on the CHU628 USB module.
An “N/A in the support column of the table indicates that the command is related to a feature that is not

available on the modems.

AT INTERFACE DESCRIPTION

1.4. Basic Integration

The MM-6280IND supports asynchronous serial communication known as RS-232 or USB.
This chapter describes the basic integration and communication of MT2 with TE2. MT2 hereby defines

MM-6280IND and TE2 means host products which can issue AT commands and handle the response
through UART or USB signalling. The popular examples of TE2 are PC’s, PDA’s and unmanned
systems such as Data Loggers, RTU’s or PLC’s.

1.5. Serial Interface

TE2’s command and MT2’s response pair is the basic interface sequence. The pairs should keep a
pre-defined format and ignore the case of letters unless otherwise specified. MM-6280IND supports 2
serial interfaces, USB and UART. USB and UART serve an AT command set with ASCII character
sequence.

1.6. Command Format

The AT command set in USB and UART is based on ASCII text. The extended AT command set by
Qualcomm start with “AT$QC” and the extended AT command set by C-motech start with “AT$$”. All
commands should finish by <CR>, 0x0d.

Any spaces in the AT command field are ignored and the space in the parameter field should be
removed if it is not necessary unless otherwise specified.

With few exceptions the following syntax provides the given response for each AT command. Where
not applicable the response is ERROR:

Table 2. AT command Format

Command Description
AT***? reads current set value
AT***=? reads supported range of values
AT***=<value> changes current set value to new set value

$$command: result
Error(In case of not applicable command, or wrong argument input)

NOTE: *** stands for the specific AT syntax.

1.9. Report Mobile Termination error( +CMEE)

Set command disables or enables the use of result code +CME ERROR: <err> as an
indication of an error relating to the functionality of the MT. When enabled, MT related
errors cause +CME ERROR: <err> final result code instead of the regular ERROR final result
code. ERROR is returned normally when error is related to syntax, invalid parameters, or TA
functionality.

+CME ERROR: <err> is the result code for any of the commands in a command line, none of the
following commands in the same command line is executed (neither ERROR nor OK result code shall
be returned as a result of a completed command line execution). The format of <err> can be either

General commands

ITU-T Recommendation V.250 [14] includes "Generic DCE Control" commands with the prefix +G.
These commands are for the identification of the TA. Four of those commands are adapted here to be
the identification commands of the MT. Syntax is otherwise similar but the prefix is +CG. TIA
IS-99 [15] uses same commands for base station identification.

1.11. Request manufacturer identification(+CGMI)

Execution command causes the TA to return one or more lines of information text <manufacturer>,
determined by the MT manufacturer, which is intended to permit the user of the TA to identify the
manufacturer of the MT to which it is connected to. Typically, the text will consist of a single line
containing the name of the manufacturer, but manufacturers may choose to provide more information
if desired.

1.12. Request model identification(+CGMM )

Execution command causes the TA to return one or more lines of information text <model>,
determined by the MT manufacturer, which is intended to permit the user of the TA to identify the
specific model of the MT to which it is connected to. Typically, the text will consist of a single line
containing the name of the product, but manufacturers may choose to provide more information if
desired.
