separate Gateways. The PPP session will be dropped and will have to be reestablished by the modem.

•Once on a new Gateway, automatic re-registration will be performed and a new dynamic IP address will be assigned to the modem.

•Roaming support for “fixed” IP addressing outside the “home” Gateway service area is not currently supported. Future design work to allow a DNS server to map IP addresses to IMSIs is envisioned, which would permit worldwide fixed IP address roaming.

If service alerts are enabled, a service alert is sent out the Data/Control port whenever the Service Provider or Gateway changes. This includes the modem changing from roaming to home service area and vice versa.

Using Asynchronous Data

The GSP-1620 modem lets the application device (DTE) connected to the modem originate or receive an asynchronous data call. It can dial or be dialed by a modem at the host server, connecting through the Globalstar Satellite Communications System and the PSTN.

Figure 5-3 shows the various modems (the GSP-1620 DCE modem, the Gateway IWF modem, and the host modem) and other components involved in an asynchronous data call.
