Site Link Operations
When you add a site link, you enter the starting and ending sites of the link 
and the maximum bandwidth and bit rates available for calls (audio and 
video) that use the link. Links are bidirectional. After you have created a link 
from Site A to Site B, you automatically have a bi-directional link from Site B 
to Site A, although the link appears as unidirectional.
Site-link operations include:
• View the Site Links List
• Add a Site Link
• Edit a Site Link
• Delete a Site Link
Note
The bit rate can be set at the network level, the device level, and the conference 
level. If there is a discrepancy between these bit rate settings, the system 
implements the lowest bit rate setting. The only exception, is that the bit rate in the 
RMX profile takes precedence over the bit rate in the conference settings.
