CHAPTER 5

Keepalive

It is not uncommon for your Raven to be disconnected from Verizon after an extended period of inactivity. This is generally a feature intended to reduce your charges for inactive use.

Keepalive is used to test and maintain the Raven’s connection to Verizon by ping- ing an IP address after a specified period of inactivity. Keepalive is recommended for users who have a remote terminated modem that infrequently communicates to the network. Keepalive is also recommended if you have experienced issues 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 modem does not receive a response from the IP address, it will retry 5 times in 5 second intervals. The Raven will then reset the radio module after 5 failed attempts and reconnect to Verizon.

Configuring Keepalive

As with all other aspects of the Raven’s configuration, you can use Wireless Ace (page 10), AceNet (page 11), direct serial communication (page 53), or Telnet (page 53) to configure Keepalive.
