connection time out is not reached. Once internal timeout reached (the 
internal timeout of the modem is fixed to 5 minutes), the connection is 
released from the modem side and the modem is ready to receive a new 
incoming set-up connection.   
 

Transmission Mode 

The data transmission is performed through the wireless LAN using TCP-IP 
protocol. The modem is ready to send or receive data when it leaves its set-
up phase.  
 
AFTER POWER-UP, NO CHARACTERS MUST BE TRANSMITTED ON 
THE SERIAL LINK DURING A MINIMUM DELAY OF 5 SECONDS TO 

ENSURE PROPER BOOT OPERATION OF THE MODEM
 

Connection of the modem on a remote server 

The modem acts as a client. It is ready to establish a remote connection after 
a delay of 5 seconds after a power-up or a set-up configuration phase. 
 
The following behaviour can only be expected if the recommended settings 
have been set on the modem (see chapter SET UP). The TCP communication 
is established by the modem when it receives any character from its serial 
link. On the first character reception, the modem tries to connect on the 
remote server specified by the remote IP and the remote port and data are 
transmitted. If the remote server cannot be reached, data sent on the serial 
link are kept in the internal modem buffer (in the limit of its size) and are 
sent when the modem finally succeeded in connecting to the host.  
 
The connection remains active while the modem is powered. If the host side 

disconnects, the modem re-attempts to connect until the connection to the 
host is successful. 
 

Connection of a client on the modem 

The modem acts as a server while it is powered. The modem is ready to 
accept an incoming connection after a delay of 8 seconds after power-up or a 
set-up configuration phase. There is no password to connect to the modem. 
The connection is never closed by the modem.
