Field  Description
Name  The name of the subnet. Required and must be unique. 
IP address  The IP address that defines the subnet. 
Subnet mask  The subnet mask, such as 255.255.255.0. 
Max bandwidth (Mbps)  The total bandwidth limit for voice and video calls. If not 
specified, the site limit applies. 
Max bit rate (kbps)  The per-call bit rate limit for voice and video calls. If not 
specified, the site limit applies. 
Note: Bit rate is not the same as bandwidth. Since the 
bit rate applies in both directions and there is overhead, 
the actual bandwidth consumed is about 2.5 times the 
bit rate selected. 
When you specify both the bandwidth and bit rate limits, 
the dialog box shows you how many calls at that bit rate 
the specified bandwidth supports. 
Note 
You can assign a subnet to only one site.
