Call Answer Testing
After powering-on the Global Premier 56 modem, use the following procedure to test the
modem’s ability to answer a call.
1.
Configure your Global Premier 56 modem to auto-answer incoming calls, as described under
“Modem Operation” on page 8.
2.
Use a telephone to call the Global Premier 56 modem. Listen to the call to verify that the
Global Premier 56 modem answers the call with its answer tone and performs its
handshaking sequence in an attempt to make a data connection. Hang up the handset of the
telephone that originated the call.
3.
Use another modem to call the Global Premier 56 modem. Verify that the Global Premier 56
modem answers the call, makes a data connection, and turns on the OH and DCD LEDs.
Call Originating Testing
Use the following procedure to test the modem’s ability to place a call.
1.
Using terminal-emulation software such as HyperTerminal, issue the AT command
ATD<your number> where <your number> is the telephone number your modem is
connected to. For example, if your modem is connected to the line 555-1212, type
ATD5551212.
2.
You should hear the modem originate the call followed by a busy signal (since the modem is
dialing its own number). In addition, a BUSY result code should appear on the computer or
DTE monitor.
If you do not hear the modem placing the call, use the ATL and ATM commands to adjust the
volume and status of the modem speaker. For more information about these commands, refer to
pages 64 and 64, respectively.
Note: If you try to establish a V.90 or V.92 connection, be sure the remote modem also
supports V.90 or V.92. Otherwise, you will not be able to establish the connection.
