8.3.3 Manually Answering Incoming Calls

It is possible to manually answer incoming calls without involving the repeater software at

all, to verify that the remote access and the network itself works as intended. In order to

verify the remote communication, make sure to have someone stand by to dial up the

repeater with a terminal emulation program, for example HyperTerminal™.

Go in to Direct Modem Access as described earlier. When in direct access mode, ask the

person standing by to dial up the repeater.

As soon as a call is received, the text RING will repeatedly be displayed on the screen.

Type ATA <enter>

This will inform the modem to answer (ATtention Answer).

When the connection is established, a connect message will be displayed including the

connection speed. Sometimes the information comes together with some miscellaneous

information, such as error correction protocols etc.

NOTE:Make sure the remote peer dials the Data Call number

If the voice number is dialed instead of the data number, or if the modem contains an illegal

modem initialization string, the message

NO CARRIER

will be displayed almost immediately.

Try to change the modem initialization string. The modem initialization string mainly used to

configure the remote communication is AT+CBST.

Successful modem initialization strings used by Axell Wireless includes (most common first):

AT+CBST=71,0,1;\Q3

AT+CBST=7,0,1;\Q3

AT+CBST=0,0,1;\Q3

AT+CBST=7,0,3;\Q3

Once the modem initialization string is entered, try again to dial up the repeater. For details

on the different modem initialization strings, please refer to the modem’s user guide.

If the setup is successful, the connect message will be brought up;

CONNECT 9600

This means that an online connection is established to the remote peer. From now on, all

characters typed on the keyboard will end up on the remote peer’s screen. Similarly, all

characters typed by the remote peer will be displayed on the screen.

In the example, the incoming

call was successfully answered,

and the remote user entered the

text message.

In order to come back to modem command mode, press +++ (three pluses) rapidly (within

one second).

Receiving OK means that the modem is back in command mode.

Type ATH <enter>

This terminates the connection to the remote peer. The message NO CARRIER will be

displayed.
