Network Topologies

Figure 2-2 Star network
The ability to configure multiple aggregate ports allows a vast range of topologies to be
built with the V200, ranging from simple point-to-point systems at one extreme to a
Star network cluster with a large number of remotes at the other. Connections may be
permanent or dynamic, the choice being made by the nature of the traffic. Data traffic
will require fixed routes, whereas voice traffic will usually be switched. Here, if in-band
signalling is specified, routes will be defined with reference to a directory of network
addresses, which relate to the decoded dialling digits.
Connections may be established between any ports in the network, including the hub.
When indirect or onward routes are implemented at the hub, voice/fax data remains
compressed.
Figure 2-3 Mesh network
The expansion capabilities of the V200 make it an ideal foundation for a full-mesh
network. Since any data port may be used as an aggregate link, complex networks may
be designed which exploit the versatility of the system. The variety of aggregate media
types supported allow point-to-point connections for data channels or IP networks to
happily co-exist alongside dynamic voice traffic or asynchronous data links.
When used in conjunction with a DAMA controller, the dynamic bandwidth and
advanced compression techniques used by the V200 can produce a highly efficient and
flexible satellite communications system.
