HUB and Terminal layout is similar and can differ in the size of the antennas and RF
equipment used, as well as by the satellite router type.
UHP-1000 routers can operate in the different modes depending on activated mode of
operations:
 SCPC – a dedicated channel mode when Terminals interact with each other or
with a HUB via fixed dedicated satellite bandwidth with a guaranteed physical
level capacity (see Figure 2). Each terminal transmits one dedicated channel that
will be received by opposite terminal. This mode is appropriate for channels with
high capacity and steady high traffic. Hub is not required in this mode.
Figure 2 Typical network diagram for SCPC dedicated channel.
 Broadcasting network with dedicated MCPC channel. There two types of Earth
Stations in such networks:
o Uplink station that is continuously broadcasting MCPC carrier that
containing information for a specific network station or for a group of such
stations. When necessary Uplink station may control the quality of its
transmission by receiving its carrier back from the satellite.
o Unlimited number of stations that are receiving the carrier from the
satellite and route any traffic intended for this destination to its LAN port.
Such stations are, normally, receive-only without any transmission path.
