5.9 Twin Mode Setup Page
The Twin Mode Setup page allows the configuration of the Redundant Twin Mode capa-
bility. Twin mode is an optional enhancement and is not activated in a standard router. If
your device does not support redundant twin mode contact Adept to find out how redun-
dant twin mode might be activated. Following is a brief description of each item listed on
the page.
Heartbeat Time: This sets the time period in milliseconds between cycles of the twin mode
monitoring packets. The active member of the redundant pair or “active twin”. Sends out
two round trip monitoring packets during each heat beat period that test both the 709.1 and
IP interfaces to both routers. The default is 1000 ms. Increasing the HeartBeat time
increases the fail over latency time. Decreasing it increases network traffic and load on the
router. A practical lower limit is 100ms.
