Along with the pre-configured default links this ensures that, by default, any zone has connectivity to all other
subzones and zones. You may rename, delete and amend any of these default links.

Note: calls will fail if links are not configured correctly. You can check whether a call will succeed, and what
bandwidth will be allocated to it, using the CLI command xCommand CheckBandwidth.

Configuring pipes
Pipes are used to control the amount of bandwidth used on calls between specific subzones and zones. The
limits can be applied to the total concurrent bandwidth used at any one time, or to the bandwidth used by any
individual call.

To apply these limits, you must first create a pipe and configure it with the required bandwidth limitations.

for more information about how the
bandwidth limits are set and managed.
Applying pipes to links
Pipes are used to restrict the bandwidth of a link. When a pipe is applied to a link, it restricts the bandwidth of
calls made between the two nodes of the link - the restrictions apply to calls in either direction. Normally a
single pipe would be applied to a single link. However, one or more pipes may be applied to one or more links,
depending on how you want to model your network.
