Manually Answering Incoming Calls
It is possible to manually answer incoming calls without involving the OMU 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 OMU 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 OMU.
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 dialled instead of the data number, or if the modem contains an illegal modem
initialization string, the message
OK
or
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
