Data Communication and Host Modes
When the Raven X obtains its IP Address from the cellular provider, it also obtains Verizon’s routing information necessary to forward messages to Verizon’s routers which can then forward on from there. The Raven X then acts as a router for the device connected to it, forwarding to or from Verizon’s network.
Caution: The forwards messages to and from the cellular network for only ONE device per port. The is a
Keepalive
Keepalive is used to test the Raven X’s connection by pinging an IP address after a specified period of inactivity. Keepalive is only recommended for users who have a remote terminated modem that infrequently communicates to the network or if you have experienced issues over time where the modem can no longer be reached remotely.
When Keepalive pings the IP address, an acknowledgement indicates there is an active connection to the network. If the Raven X does not receive a response from the IP address, it will make addi- tional attempts according to a backoff algorithm before determining the Internet connection is not functioning properly. If it determines the connection is not fucntioning, the modem will then attempt to reconnect to Verizon to reestablish IP connectivity.
Configuring Keepalive
You can use Wireless Ace or a terminal connection to configure Keepalive (page 47). In Wireless Ace, select Other from the groups menu on the left.
FIGURE 8. Wireless Ace: Keepalive Configuration
*IPPING sets the interval, in minutes, you want Keepalive to test the network connection. To disable Keepalive, set *IPPING to 0 (default setting).
Note: 60 minutes is the minimum time which can be set for Keepalive.
*IPPINGADDR sets the IP address you want to use for the connection test.
