1. GENERAL DESCRIPTION
1.1 System overview
1.1.1 Purpose
UHP satellite routers are essentially a universal solution for geographically distributed VSAT-class satellite
communication networks. UHP routers can be used to organize simple point-to-point channels, “star”- and
“mesh”-topology networks with several hierarchy levels and bandwidth-on-demand capabilities.
UHP-8000 dual satellite router is an integrated chassis with two UHP-1000 routers and IF subsystem that can be
used as two independent routers or as elements of some complex system (e.g. Hub, redundant modules, etc.).
1.2 Router composition
UHP-8000 router consists of:
1. Integrated UHP-1000 satellite router “A”;
2. Integrated UHP-1000 satellite router “B”;
3. IF subsystem with combiner and divider;
4. Integrated power supplies (individual for each router);
5. 1U rack-mountable chassis
1.3 Measurement equipment, tools and accessories
Standard computer (notebook) is required to configure and monitor status of UHP-8000 satellite router. The
computer must be equipped with a LAN interface and USB, and also have the following software installed:
Internet browser (WEB browser)
Telnet Client
The Terminal (e.g.: Hyperterminal, included in the OS Windows) (optional)
The router can be accessed via LAN or USB ports. Standard USB AM/BM cable (not supplied) is required for
connection to USB “Console” port of the satellite router.
Connection of a computer to the router via LAN interface is implemented through the Ethernet switch or hub via a
standard network cable with RJ-45 connectors (not supplied).

1.4 Labeling and sealing
The product is marked with the unique Serial Number on the bottom of the router’s case.
The warranty seals are located on the bottom of the product, at the junction of the two parts of the case.
Product’s warranty will automatically void if such labels have been removed, modified or damaged.
1.5 Packaging and content
Satellite router comes as an integrated chassis. It is recommended to keep original packaging throughout the
entire lifetime. Conservation, storage and transportation of the terminal must be in original packaging.
Standard package includes:
1. UHP-8000 dual satellite router
2. Power cables

All the interfaces are located on the rear panel of the device. The indicators are located on the front panel.
Indication of each integrated router is located on the front panel of the chassis and similar to the standard display
of UHP- 1000 router. Indications on the left side of the front panel are related to the router "A", the indications on
the right side correspond to the router «B». The LAN and USB interfaces of each router are located on the rear

USB PORTS MAY NOT BE AVAILABLE ON SOME VERSIONS OF UHP-8000 ROUTERS.
Depending on the ordered product’s configuration (mode of operation), interconnectivity of internal modules can
be configured with a different scheme. It applies only to connection of modulators and demodulators to interface
module (IF divider and combiner).
In the basic configuration (Figure 4) outputs of the modulators are summarized on the IF combiner ("Tx" output).
The IF combiner provides the transmission of IF signals, and can also transmit DC supply voltage and/or 10MHz
frequency reference for a BUC. Input signal from the "Rx" input is divided and fed to the inputs of all the
demodulators. The divider also provides a pass of DC and/or 10MHz reference frequency for LNB.
In HUB configuration (HBIC) (Figure 5) a high-speed demodulator of the satellite router “B” (acting as IC) is
connected to a «TAP» output of the IF combiner (“Tx” output) that allows synchronizing the router "B" with the
router “A” (acting as HB).
In dual Inroute configuration (ICIC) the “Tx” interface is used to input an Outroute signal from an external HB
module. This signal is divided and distributed to each of the high-speed demodulators for synchronization (see
Figure 6).
Figure 5 Internal configuration of UHP-8000 in Hub (HBIC) mode
1.6.2 Power connector (Power input A/B)
UHP-8000 router is powered with 100-240 VAC. UHP-8000 chassis has two independent power supplies (with
individual AC inputs) for each of the router respectively.
1.6.3 USB CONSOLE (USB A/B)
USB console ports provide local control of each of the integrated routers.
1.6.4 IF input (RX)
The RX interface is an input of the divider that distributes signals to the demodulators (see also 0). The router may
feed this input with 18 VDC power supply. Whether power source is on or off, the input can withstand external

voltage up to 50 VDC (power supply circuit is provided with a diode). 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 the Rx input 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.
THE TOTAL CURRENT CONSUMED BY EXTERNAL EQUIPMENT SHOULD NOT BE IN EXCESS OF 750 MA. NORMALLY,
CURRENT CONSUMPTION BY DRO LNB -<150 MА, PLL LNB -<500 MА.
Figure 6 Internal configuration of UHP-8000 in dual Inroute (ICIC) mode
1.6.5 LAN interface connector (LAN A/B)
LAN connectors are purposed for connecting to Ethernet switch using a straight cable. These connectors are
connected directly with respective LAN outputs of the integrated routers. Bit rate 10 or 100 and duplex mode are
software selectable.
1.6.6 Modulator output (TX)
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 .SUPPLYING MORE THAN 24 VIS
PROHIBITED.
The purpose of “Tx” interface depends on the factory-selected mode of operation (see 0). The interface provides
transmission of IF signals, 10 MHz reference and 24 VDC power supply (if activated on the router).
WARNING! THE SUPPLY VOLTAGE AND THE REFERENCE SIGNAL SHOULD BE ACTIVATED ONLY ON THE ONE OF THE
ROUTERS!
UHP-8000 modulators are compatible with most satellite transmitters/converters (BUC), except that require to
explicit “TX On” FSK command.
