Modem Application Scenarios

Depending on the requirements of your SCADA or OEM application, you can configure the GSP-1620 modem to work in many different ways, using many different features. The following are sample scenarios for how the modem might work in a SCADA setting:

•Scenario 1 — Full-time packet data on-demand:

❑The modem can both generate data or accept it from the Gateway (see Mobile-Originated Packet Data Calls on page 5-27 and Mobile-Terminated Packet Data Calls on page 5-27).

❑The modem uses dormant mode, where traffic channel is automatically reestablished upon receipt of PPP traffic at the modem end or IP traffic at the Gateway end (dormant mode works for packet data only).

❑Since the application developer is responsible for security issues, the application might want to query for a password or answer calls only at certain times or only from certain phone numbers.
