Voicemail
If a Voicemail message has been left for you, the RST 100 flashes the Voicemail
Waiting indicator (subject to network support). The indicator is cleared whenever the
user connects to the Voicemail retrieval number programmed in the RST 100.
Short Message Service – SMS
If an SMS has been sent to the user, the RST 100 flashes the SMS Waiting indicator.
This means that the SMS is ready to be read. The indicator is cleared when the SMS
has been read and cleared from the RST memory.
See the section
Connecting a PC
for details of how to connect a PC to the RST to
read and send SMS messages.
Facsimile Support
The Iridium network does not support facsimile transmission.
Use of the RST100 with a PABX
The RST100 RJ11 port presents as an FXS line, that is it looks like an exchange or
central office line to a standard DTMF telephone attached to the RJ11 analog port.
If instead of a standard telephone, a PABX is connected, then the RST100 is
performing the role of the network trunk as shown below:

The RJ11 port of the RST100 is set to a default setting, which is intended to operate
out-of-the-box with most phones and PABXs available. This default setting is known
as “International Default” within the Beam Management System.
The International Default sets the line impedance to 600 Ohms and the levels in the
up and downlink directions to suit the expected deployment scenarios. Specific
implementations and terminal equipment may require adjustment of these
parameters in association with your Service Provider.
