Modem Initialization Strings
Initialization Strings
Enter the modem initialization string. An initialization (init) string is a list of commands sent to the
modem to initialize and prepare it for a connection. The init string typically sets options such as
speed, error correction, compression, various timeout values, and how to display results to the user.
For EDGE, type
AT+CGDCONT=1,"IP","<APN>"
(CDMA does not need an initialization string).
Note:
The APN (Access Point Name) is assigned by your wireless service provider. An access point
is an IP network to which a mobile device can be connected.
Click the
Save
button after the initialization strings are entered.
SIM Initialization String (for GSM/EDGE Cellular only)
Initialization String
Enter the SIM initialization string. The SIM initialization string is sent to the cellular modem during
boot up in order to initialize the Cellular SIM. This is not applicable for analog modems. Click the
Save
button after the initialization string is entered.
Signal Strength (for Cellular only)
Command
Enter the command or use this default command to find out the cellular signal strength. This is not
applicable for analog modems. Click the

PPP Keep-Alive Parameters
PPP Ping Keep-Alive
Check this box to enable the PPP Keep-Alive function on the dial backup link. Once the link is up, this
option checks whether the PPP link is alive or not by periodically pinging to the Keep-Alive URLs at a
specified interval. This will not occur when the link is down.
Keep-Alive Interval
Enter the amount of time in seconds that the pinging to the Keep-Alive URLs should occur.
Keep-Alive Counts
Enter a number that specifies how many ping packets should be sent to each URL. The default is 10.
Click the
Save
button.
PPP/Internet Keep-Alive URLs
Internet Keep-Alive URLS
The two URLs you enter here will be used to check to see if the Internet is reachable through the
WAN/PPP links. If the Internet is not reachable through the WAN link, then the link is assumed to be
down and all the traffic will be forwarded through the PPP link. The same URLs are used for the PPP
Keep-Alive function. These URLs can either be a valid domain or a valid Public IP address.
Example: www.google.com. Click the
Save
button.
