Configuring PPP: Sending modem commands to the integrated modem on router
You can allow an external application to query modem information by setting up certain modem commands.
The application can use the URL HTTP://xxxU.xxx.xxx.xxx/modeminfor.htmlU to get the IP address that is currently assigned to the integrated cellular modem after the PPP connection is established. This URL also shows the results of up to ten AT commands entered here.
Configuring Modem AT Commands
These commands are sent every time a PPP connection to the network is initiated.
Example of Useful HSPA AT Commands:
AT+CGSN | Product Serial Number |
AT+CGMR | Software Version |
AT+CSQ | Signal Quality |
AT+CNUM | Wireless Subscriber Number |
AT+COPS? | Network Information (Operator) |
AT+CREG? | Network Registration |
Example of Useful EV‐DO AT Commands:
AT+CGSN | Product Serial Number |
AT+CGMR | Software Version |
AT+CSQ | Signal Quality |
Setting up wake up on call
Configuring wakeup‐on‐call
The Wakeup‐on‐Call feature allows the router to wake up and initiate a connection when there is an incoming call or LAN activity. The Wakeup‐on‐Call feature can reduce costs when a router is online and available 24/7.
To have some security surrounding this feature, you can set up the router to wake up based on receipt of a particular Caller ID or SMS instead of allowing all incoming calls to wake up the router.
You must enable Dial‐on‐Demand for these settings to impact the router's operation. For more information about dial‐on‐demand, see Configuring general PPP features.
To configure wakeup‐on‐call:
1.From Cellular, select Wake Up On Call.
