3.2 CSD Connection

3.2.1 Overview

A Circuit-Switched Data Connection makes the wireless modem work in a manner similar to a regular analog modem.
CSD (Circuit Switched Data) is the original form of data transmission developed for cellular systems. By using a single
radio time slot, CSD is able to deliver 9.6 to 14.4 kbit/s data transmission to both the CELLULAR Network and PSTN
Switching Subsystem through direct calls. Most of the time, it is initiated by standard AT commands. Using the
modem to access remote devices by CSD is often more convenient than installing cables and data lines. Data
collection and monitoring will be more flexible since CSD can be used for applications that are hard to wire or hard
to access.

Note: Ensure that your SIM card has the CSD Service activated. For most regions, you must apply to your mobile
service provider to receive this service.

3.2.2 Establishing a CSD Connection

1. Start SecureCRT with serial parameters 115200,8,n,1.

2. Type ATD <phone number> and press Enter to establish a CSD connection. (e.g. ATD 123456, in which 123456 is

the phone number.)

3. After remote side answering the CSD call, then the CSD connection has been established successfully.

4. To close the CSD connection, type +++. The modem will respond with OK to indicate that you have already

switched back to the command mode. It means you can enter AT commands again via SecureCRT.

5. Type ATH and press Enter to disconnect.

Robustel GoRugged M1000 UP User Guide

RT_UG_M1000 UP_v.1.1.1 07.10.2015 22 / 39

Note:

 +++ is the escape sequence, and ATH is the hang-up command.
 For international calls, the local international prefix does not need to be set, but does need to be replaced by

the + character. E.g., you would type ATD+86123456, in which +86 is the country code.

3.2.3 Answering a CSD Connection

1. When secureCRT displays the RING response, type ATA, and press Enter.

2. In the secureCRT window, type ATS0=x and press Enter. For x, substitute the number of rings that the modem

should receive before answering the call. For example, to answer after the first ring, type ATS0=1.

3. Type AT&W and press Enter.

Robustel GoRugged M1000 UP User Guide

RT_UG_M1000 UP_v.1.1.1 07.10.2015 23 / 39

4. To close the CSD connection, type +++. The modem will respond with OK to indicate that you have already

switched back to the command mode.

5. Type ATH and press Enter to disconnect.

3.3 Using Short Message Service

Chapter 4 Appendix

4.1 GSM Alphabet

Standard SMS can contain 160 characters. However, the characters typed must be part of the so-called 7-bit default
alphabet as specified by GSM 3.38. You can see in the table below that this alphabet contains all ASCII characters and
some accented characters.
For example, u umlaut (ü) and e with grave (è), are in this set. Please study the table below to have a complete
overview. Using any character not in this set, will make the SMS a Unicode SMS and limit the length of the SMS to 70
characters.
Note: a few characters actually count as two characters. These characters are:
{}[]~|\ and the Euro symbol: €
You can also see that in the table below in the hex column. These characters need to be escaped.
Below is the 7 bit default alphabet as specified by GSM 03.38. The corresponding ISO-8859-1 decimal codes are
shown in the rightmost column. Note that the euro sign (€) is also included.
