connection failure check box to force the Gateway to unregister from
its gatekeeper when both ISDN D-channel connections are no longer
active. The gatekeeper is forced to send new IP-to-ISDN calls through a
different Gateway, thus ensuring high call completion rates. The
Gateway re-registers to the gatekeeper when the ISDN connected is
restored.

no cable is connected check box to force the Gateway to unregister
from its gatekeeper when no cable connection is found. When at least

automatically unregistered from the gatekeeper (see

Select the Send load balancing messages (RAI) check box to enable
the sending of RAI messages to the gatekeeper for the purpose of load
balancing on the network. If you select this option, perform
step
14.
Gatekeepers can perform load balancing on the network using feedback
from the Gateway in the form of Resource Available Indication (RAI)
messages that inform the gatekeeper of Gateway resource availability. If
the Gateway is unavailable, the gatekeeper performs line hunting
operations to route the call to an alternative gateway.
When you set the Gateway for RAI/RAC, it sends periodic RAI
messages that inform the gatekeeper of the current resource availability
in the Gateway. The gatekeeper responds with Resource Available
Confirmation (RAC) messages to acknowledge receipt of the RAI
messages. In
