Bandwidth on Demand
Bandwidth on Demand is a feature providing additional link bandwidth in a
network during times of higher bandwidth usage. This feature allows nodes
in a network to activate and deactivate their WAN links based on a
configured time schedule. This additional bandwidth can be provided by an
additional link, or more likely, by a secondary link.
The Time of Day function sets the time schedule for the Bandwidth on
Demand feature to occur. It ensures that the additional bandwidth will only
be available during certain time periods. Parameters defining the activation
and deactivation thresholds are configurable. Once an event (activation or
deactivation) has occurred, then the minimum time interval before the next
event can begin is ten minutes.

The secondary link operates in conjunction with a primary interconnect link
to provide link redundancy in the event of link failure or over utilization
(assuming power and telephone communications are maintained). An
interconnect link is considered a primary interconnect link if it has an
associated secondary link.
A port is configured as a secondary interconnect link only at the side of the
link that will initiate the call (originate). At the answer side of the link (the
one receiving the call), configure the port as an interconnect link.

Note: One side of the link must be originate and the other answer. Therefore, a
secondary link on one side will always connect to an interconnect link on the
other side.
