Lets you edit a site in the Polycom RealPresence DMA system’s site topology and add or edit a subnet 
associated with the site. The following table describes the fields in the dialog. 

IP Address 

The IP address of the subnet. 
You can define overlapping subnets; larger subnets can contain smaller ones. 
When the system determines which subnet a given IP address belongs to, it 
chooses the subnet with the longest IP address match. For example:

subnet1 = 10.0.0.0/8
subnet2 = 10.33.24.0/24
The IP address 10.33.24.70 belongs to subnet2. The IP address 
10.22.23.70 belongs to subnet1.

Subnet Mask Length

The CIDR (Classless Inter-Domain Routing) prefix size value (the number of 
leading 1 bits in the routing prefix mask). This value, together with the IP 
Address, defines the subnet. 
For IPv4, a value of 24 is equivalent to specifying a dotted-quad subnet mask 
of 255.255.255.0. A value of 16 is equivalent to specifying a subnet mask of 
255.255.0.0. 
You can use subnet mask lengths of up to 32 bits; a 32-bit subnet mask allows 
you to specify a single device.

Max Total Bandwidth (Mbps) 

The total bandwidth limit for voice and video calls. 

Max Per-Call Bit Rate (kbps) 

The per-call bit rate limit for voice and video calls. 
When you specify both the bandwidth and bit rate limits, the dialog shows you 
how many calls at that bit rate the specified bandwidth limit supports. The 
value of the Bit rate to bandwidth conversion factor setting on the 

 page is used in this calculation.
