line interface on a remote host via a virtual terminal connection.
Terminal
Earth Stations (usually VSAT) operated under management of network HUB
TFTP
Trivial File Transfer Protocol (TFTP) is a file transfer protocol, with the functionality of a very basic form of
File Transfer Protocol (FTP).
UDP
The User Datagram Protocol (UDP) is the set of network protocols used for the Internet. With UDP,
computer applications can send messages, in this case referred to as datagram, to other hosts on an
Internet Protocol (IP) network without requiring prior communications to set up special transmission
channels or data paths.
USB
USB (Universal Serial Bus) is a specification to establish communication between devices and a host
controller (usually personal computers).
VLAN
A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that
communicate as if they were attached to the same broadcast domain, regardless of their physical location.
VoIP
Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery
of voice communications over IP networks such as the Internet or other packet-switched networks.

1.1.4 Principles of operation
UHP-1000 Satellite Router is an in-door part of Satellite Earth Station. The outdoor part of the Earth station
consists of:
Satellite antenna;
Block Up-Converter (BUC);

Low-noise converter (LNB);
Pair of coaxial cables connecting Outdoor and Indoor units.
Figure 1 Satellite communication terrestrial station layout
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:
oUplink 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.
oUnlimited 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.

Figure 3 Typical network diagram for MCPC broadcasting.
TDM/TDMA network –a network mode with dynamic redistribution of satellite network capacity
consisting of Hub and Terminals. The TDM/TDMA network consists of:
oHub is a central station of the network that is managing operations of all Network Terminals
and distributing the bandwidth accordingly to actual traffic load and predefined QoS. Hub is
also acting as a gateway, concentrating and routing traffic of all Network Terminals to/from
external networks. Hub consists of one or several UHP-1000 routers depending on network
size. (See Figure 4)
Hub constantly broadcasts common MCPC carrier - Outroute (1) dedicated to all network
Terminals. Hub uses Time Division Multiplexing (TDM) to deliver data to specific terminal or
to some group of terminals. Such data consists of user traffic and network management
commands.
Hub receives its Outroute channel from the satellite for calculation of the Time To Satellite
(TTS) delay that is required for network synchronization.
oTerminal - is network access equipment that interacts with the Hub in Hub/Spoke (Star)
topology. Terminals receive the MCPC Outroute (1) broadcasted from the Hub and respond
to the Hub via Time Divided Multiple Access (TDMA) carrier - Inroute (2). One or several
TDMA Inroutes are shared between groups of Terminals. Each Terminal transmits its
information as packets (burst) to individually-assigned time-slot determined by the Hub.
oMesh Terminal –an advanced mode of operation of basic Terminal that allows
simultaneously receiving information from the Hub and other remotes. Mesh Terminal is
also based on UHP-1000 router, but with enabled burst demodulator (which is software
activated option of any UHP-1000 router). In such advanced mode Terminals may exchange
information in-between each other in one-satellite hop without any transit via Hub. Mesh
Terminals allow creating network of any topology e.g. "tree", "star of stars", ”Mesh”, etc.

Figure 4 Typical TDM/TDMA network diagram.
HUBLESS TDMA Network (see Figure 5) consists of equal Earth Stations (Hubless Stations) that
interact with each other through a common TDMA channel (1). This channel is used by all Hubless
Stations to send and receive information with dynamic reallocation of the resource on demand.
Theoretically, all network resources can be concentrated just for transmission or receive of one
particular Network Station, if no other traffic in the network.
One of the Network Stations acts as a Master and takes over the functions of dynamic network
resource allocation between other Stations. To ensure Mesh interactions between all the Stations a
satellite link budget should be designed in such a way that all Stations properly receive each other.
The minimum criterion is that all Network Stations properly receive the bursts of Master Station and
vice versa. However, the network designed under such minimal criteria will behave as Star-topology
system with a center at the Master Station.
High-speed demodulator in Hubless TDMA network is not in use and can be used to receive some
additional traffic via MCPC carrier, such as broadband Internet. It could be a carrier from the same or
from another satellite.

1.2 Description and principles of operation
1.2.1 Overview
Each module of -1000 satellite router has its own interface to external devices. All the interfaces are
located on the rear panel of the device. The indicators are located on the front panel. LAN Indicators are
integrated into the LAN connector on the back of the router.
Figure 8 UHP-1000 series modem –rear view
1.2.2 Power connector (DC IN)
UHP-1000 router is powered with 24 VDC. AC Power supply adaptor is supplied with the set. The router can be
powered from a DC power source (batteries, DC-DC converter), but the specific power supply mode should be
agreed upon with the Manufacturer. Power supply connector features dimensions 5.5 / 2.1 mm (outer and inner
diameters). Positive terminal of the source is on the central contact.
1.2.3 LAN interface connector
LAN connector is purposed for connecting to Ethernet switch using a straight cable. Bit rate 10 or 100 and duplex
mode are software selectable. Indicators built into the connector mean the following: left one (green) –
connection (Link) and data transmission (Activity), the right one –yellow) –activation of half-duplex mode.
1.2.4 USB CONSOLE
The console port provides local control of the device.
1.2.5 RESET button
Router reset is provided using this button. Also, using special combination of pressings this button allows router
reset to factory settings.

Figure 9 Radio equipment power supply control.
1.2.6 High-speed demodulator IF input (SCPC RX)
SCPC-RX is one of the two signal inputs to receive signals from the satellite (LNB). This input is designed to receive
continuous (SCPC/MCPC) carriers in DVB-S and DVB-S2 formats from the satellite. The input, on the router side,
can be fed with 13 or 18 V power supply. Whether power source in on or off, the input can withstand external
voltage up to 50 V (power supply circuit is provided with a diode). Short circuiting is not welcome since it creates
high load on the device. Power supply circuit is protected with a thermal fuse operating in case of short circuiting.
After short circuiting is removed it may be required to disconnect load from Rx inputs for several seconds so as to
allow the fuse to return to its initial state.
Cable length and cable quality (losses level) can affect the quality and possibility of receiving signals.
1.2.7 Burst demodulator IF input (TDMA RX)
TDMA-RX is the second input for the signal from the satellite (LNB). This input is designed to receive bursts (TDMA)
in UHP proprietary format. The input can also provide, from the router side, supply voltage 13 or 18 V, similar
voltages being simultaneously fed to both inputs. The router can feed this input with a reference signal for using
PLL LNB requiring external reference signal. When reference signal is switched off the router will not distort
reference signal arriving at the input from outside. The rest conditions are similar to those across SCPC RX.
THE TOTAL CURRENT CONSUMED BY EXTERNAL EQUIPMENT THROUGH BOTH RX INPUTS SHOULD NOT BE IN EXCESS OF
750 MA. NORMALLY,CURRENT CONSUMPTION BY DRO LNB -150 MА, PLL LNB -500 MА.

1.2.8 Modulator output (TX OUT)
TX OUT OUTPUT CAN FEATURE 24 VDC WITH A HIGH SHORT-CIRCUIT CURRENT.SHORT CIRCUITING CAN CAUSE
SPARKLE SPREAD AND BURNS.THIS VOLTAGE CAN DAMAGE MEASUREMENT EQUIPMENT IF IT IS NOT PROTECTED AT ITS
INPUTS.SUPPLYING EXTERNAL VOLTAGE TO THIS CONNECTOR IS OBJECTIONABLE AND SUPPLYING MORE THAN 24 VIS
PROHIBITED.
UHP-1000 modulator is compatible with most satellite transmitters/converters (BUC). Those incompatible are only
transmitters that require to explicit “TX On” FSK command but such transmitters are extremely rare and are not
widely employed.
Modulator is connected directly to the transmitter IF connector. Router provides 24 VDC power supply to the
transmitter and 10 MHz reference signal. UHP-1000 is not provided with a separate protection on the transmitter
power supply circuitry. Use is made of current protection for the power supply adapter. In case of a short circuit
the router is de-energized and then gets restarted. If power supply is switched on in the configuration, restarts
continue at 5 seconds interval until short circuiting is removed.
ANY OPERATIONS WITH IF TX CABLE SHOULD BE PERFORMED WITH 24 VSUPPLY VOLTAGE TURNED OFF.OTHERWISE,
SELF-INDUCTION ACROSS A LONG CABLE CAN DAMAGE THE TRANSMITTER AND/OR ROUTER.
1.2.9 “ERROR” Indicator
“ERROR” red indicator makes it possible to infer about problems in the router functioning. The type of the
generated problem can be judged by the number of indicator flashes:
1 –Demodulator cannot receive MCPC channel from the Hub (other Terminal). Please check AGC value in the
demodulator statistics to determine whether there is a signal from antenna (see description of reception
problems) to separate LNB and cable faults.
2 –Router cannot receive TDMA configuration from the HUB (TDM/TDMA network mode). The reason can be in
the non-availability of receive channel from the HUB, CRC errors during reception, wrong configuration of the
Terminal.
3 - Router cannot calculate time shift with respect to the HUB. The reason can be in the non-availability of
reception or a large number of CRC errors during reception.
4 –HUB cannot receive signal from this terminal. Please check transmit signal level of the terminal, whether power
supply and the reference signal for the transmitter are switched on (or off if required), whether DTTS or
geographical coordinates are set correctly in the TDMA settings.
Continuous signal means that the router has hardware or configuration errors, which can be viewed with the
command "show errors" (see paragraph 2.2.10)

1.2.10 “STATUS” Indicator
“STATUS” green indicator indicates the router operation mode. This indicator is always flashing. If it does not flash
it means that the router is not functioning (please check power supply). Slow flashing (once every second) means
router normal operation. Faster flashing (3 times every second) means that a Telnet remote control session is
established (in this case USB console does not operate until session is over).
Fast (6 times every second), simultaneous flashing of “ERROR” and “STATUS” indicators means that the router is
functioning with the factory default configuration. Access to the router in this mode is possible either via USB of
via IP-address 192.168.222.222 (mask 255.255.255.248 or /29).
1.2.11 “LOCK” Indicator
“LOCK” green indicator indicates whether the router receives a channel from the central station. If there are CRC
errors during reception of information from the channel (e.g. with weak signal from the antenna), the indicator
extinguishes for a fraction of a second at every error. If there are too many errors the indicator may not glow at all
in spite of the fact that the router receives the channel (in this case please check the router demodulator
statistics).
1.2.12 “TDMA” Indicator
“TDMA” yellow indicator flashes every time a data placket is received via TDMA RX interface.
1.2.13 “SCPC” Indicator
“SCPC” yellow indicator flashes every time a data placket is received via SCPC RX interface.
1.2.14 “TX” Indicator
“TX” yellow indicator flashes every time a data placket is transmitted in the MCPC mode, and also a blank packet –
in the TDMA mode (if no data is available for transmission).
