Developing Modem Applications

•Reverse Link (Modem Transmit): 1610.73 to 1625.49 MHz

Short Messaging Service (SMS)

The GSP-1620 modem supports IS-637 Mobile Terminated Short Messaging Service (SMS). This is a separate feature from data (packet and/or asynchronous), and may be billed differently by the Service Provider.

Mobile-terminated SMS allows the host application to “send” numeric, alphanumeric, or binary messages to the GSP-1620 modem. These messages are passed transparently out the Data or Control RS-232 ports to the DTE (SCADA application). The modem makes no attempt to construct ASCII character data. If “control” data is sent to the modem via the SMS option, it will be passed along transparently to the DTE application.

The SMS feature is fully functional even if the GSP-1620 modem is active on a data call, because SMS can be accessed on the Control port. Therefore, the host application can send command and control information to the modem either while it is in a data session, or idle (not in a call).

Check with your Globalstar service provider to see whether the SMS

 

feature is available.

SMS Alerts

SMS “alerts” are asynchronous messages sent out of the Data or Control port to the DTE application upon receipt of the SMS message (see Using Data and Control Ports on page 5-7 for a more detailed explanation).

Port configuration determines how SMS alerts are received:

•If the application is using the Control port, SMS alerts are received on the Control port, even if a call is active.

•If the application is using the Data port only, the SMS alert will be queued until the data session is terminated.
