Site Links
The Site Links page contains a list of the links defined in the site topology. A link can connect two sites, or
it can connect a site to an MPLS network cloud (see Network Clouds on page 297). Links between sites
must be configured in order to enable calls between sites. In order for an endpoint in site A to call an
endpoint in site B, there must be a link path (either direct, via other linked sites, or via an MPLS network
cloud) connecting site A and site B.
If the system is integrated with a Polycom RealPresence Resource Manager or CMA system, it receives this
information from that system, and this page is read-only. If not, you can enter link information.
The commands in the Actions list let you add a link and edit or delete existing links.
The following table describes the fields in the list.
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.
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.
Column Description
Name Name of the link.
Description Description of the link.
From Site The originating site of the link. Can’t be changed when creating a site-to-cloud
link.
To Site The destination site (or MPLS cloud) of the link. Can’t be changed when
creating a site-to-cloud link.
