Applying Pipes to Links
Pipes are used to restrict the bandwidth of a link. When a pipe is applied to a link, it will restrict the bandwidth of calls made between the two nodes of the link - the restrictions will apply to calls in either direction.
VCS CONTROL 
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 wish to model your network.
One Pipe, One Link
Applying a single pipe to a single link is useful when you wish to apply specific limits to calls between a subzone and another specific subzone or zone.
One Pipe, Two or More Links
Each pipe may be applied to multiple links. This is used to model the situation where one site communicates with several other sites over the same broadband connection to the Internet. A pipe should be configured to represent the broadband connection, and then applied to all the links. This will allow you to configure the bandwidth options for calls in and out of that site.
Example
In the diagram opposite, Pipe A has been applied to two links: the link between the Default Subzone and the Home Office subzone, and the link between the Default Subzone and the Head Office subzone. In this case, Pipe A represents the Head Office’s broadband connection to the internet, and would have total and
Two Pipes, One Link
Each link may have up to two pipes associated with it. This is used to model the situation where the two nodes of a link are not directly connected, for example two sites that each have their own broadband connection to the Internet. Each connection should have its own pipe, meaning that a link between the two nodes should be subject to the bandwidth restrictions of both pipes.
Example
In the diagram opposite, the link between the Default Subzone and the Home Office Subzone has two pipes associated with it: Pipe A, which represents the Head Office’s broadband connection to the internet, and Pipe B, which represents the Home Office’s
Each pipe would have bandwidth restrictions placed on it to represent its maximum capacity, and a call placed via this link would have the lower of the two bandwidth restrictions applied.
