Data Rate and Throughput

For asynchronous data, the GSP-1620 modem offers full duplex transmit and receive at a Data port rate of somewhat less than packet data’s 9600 bps, due to additional overhead for asynchronous data. Similarly, the measured effective “user” throughput (that is, customer data) is somewhat less than the 7400 bps (average) for packet data. Asynchronous connections take longer because of PSTN modem training time.

Tip

QUALCOMM Globalstar packet data service has a lower overhead and

 

faster connection time than asynchronous data does. If your SCADA

 

application does not specifically need asynchronous data, use packet

 

data instead.

Mobile-Originated Asynchronous Data Calls

The GSP-1620 modem lets the application device (DTE) connected to it originate an asynchronous data call.

 

Steps

TO MAKE A MOBILE-ORIGINATED ASYNCHRONOUS DATA CALL

 

 

1

 

 

2

 

■ Use the ATD<dial string> command.

3

 

The modem returns CONNECT if the call has been established (for other result codes, see Dial (D) on page 6-20).

Steps TO HANG UP AN ASYNCHRONOUS DATA CALL

1.Enter Online-Command mode by using the in-band control data escape sequence, “+++” surrounded by guard time (for details, see Change from Online to Online-Command Mode (+++) on page 6-40).

2.Use the ATH command.

Note

The ATH777 command, which hangs up a packet data call and leaves

 

dormant mode active, will also hang up an asynchronous data call.
