Applying Bandwidth Limitations to Subzones
You can apply bandwidth limits to the Traversal Subzone as follows:
You can apply bandwidth limits to the Default Subzone, Traversal Subzone and all manually configured subzones.
The limits you can apply vary depending on the type of subzone, as follows:

For all the above limitations, the Bandwidth restriction setting has the following effect:
■
No bandwidth: no bandwidth is allocated and therefore no calls can be made.
■
Limited: limits are applied. You must also enter a value in the corresponding bandwidth (kbps) field.
■
Unlimited: no restrictions are applied to the amount of bandwidth being used.
Use subzone bandwidth limits if you want to configure the bandwidth available between one specific subzone and all
other subzones or zones.

Use pipes if you want to configure the bandwidth available between one specific subzone and another specific

If your bandwidth configuration is such that multiple types of bandwidth restrictions are placed on a call (for example,
if there are subzone bandwidth limits and pipe limits), the lowest limit will always apply to that call.

How different bandwidth limitations are managed
In situations where there are differing bandwidth limitations applied to the same link, the lower limit will always be the
one used when routing the call and taking bandwidth limitations into account.
one used when routing the call and taking bandwidth limitations into account.
For example, Subzone A may have a per call inter bandwidth of 128. This means that any calls between Subzone A
and any other subzone or zone will be limited to 128kbps. However, Subzone A also has a link configured between it
and Subzone B. This link uses a pipe with a limit of 512kbps. In this situation, the lower limit of 128kbps will apply to
calls between the two, regardless of the larger capacity of the pipe.

In the reverse situation, where Subzone A has a per call inter bandwidth limit of 512kbps and a link to Subzone B with
a pipe of 128kbps, any calls between the two subzones will still be limited to 128kbps.
