Short Message Service (SMS) for GSM
The SMS for GSM module must be installed on the Xpressions server to allow the functions
described below to be used. Please consult your system administrator if you have any queries.
5.1
Overview
The short message service (SMS) for GSM (global system for mobile communications) enables
you to use a standard mail program to send short messages to GSM network users, i.e. to mo-
bile phone users in the supported mobile network (for example, D1 and D2).
This service also allows SMS scenarios to be implemented, for example gathering Internet in-
formation and sending it as a short message.
5.1.1
Application Options
To use SMS for GSM, you can select any e-mail client that provides the facility to send e-mails
via STMP. This includes programs such as Eudora or the integrated e-mail clients in WWW
browsers such as Netscape Messenger and Microsoft Outlook Express. You can also use SMS
with MS Exchange (either in the way described here or using an installed Xpressions Exchange
connector as described in Section 2.5.3.1, "Sending Messages using SMS as an Example").
5.1.2
SMS Features for GSM
Messages that are sent with SMS for GSM are not sent via the usual fixed network and
●
SMS provider. SMS for GSM therefore reduces costs.
Two GSM 900 networks are supported in each country. These are D1 (Telekom) and D2
●
(Vodafone) in Germany and A1 and A max in Austria.
An SMS message may be up to 160 characters long. Your system administrator can con-
●
figure the way in which your system handles messages that exceed this length:
a) the message is not sent,
b) only the first 160 characters are sent,
c) only the first line is sent,
d) all lines up to the first blank line are sent,
e) combination of b) and c)
f) combination of b) and d)
Approximately 300 messages can be sent per hour for every connected transmitter.
●
Special characters are permitted in the message. Some special characters may be trans-
●
ferred incorrectly, depending on the service center selected.
