IntroductionC5/K1/K3 Integrated Satellite Terminal System
1.1.1 Description
The SDT-5200 indoor unit (IDU) is a 1 RU rack-mounted module that includes all the
functionality of a variable data rack modem, along with the high-stability reference and
power supply for the ODU.
Microcontrollers in both the IDU and ODU monitor and control all operational
parameters and status of the system. The system also reports terminal configuration
status, as well as fault status of all system components. A simple command set allows
configuration, control, and retrieval of status information.
The C-Band satellite terminal system is divided into three areas of operation:
1. SDT-5200 Indoor Unit (IDU). A complete, variable data rate modem, high
stability references, and power supply for the ODU in a 1 RU package.
2. Outdoor Unit (ODU). A weatherproof C-Band up converter/power amplifier and
a low noise block (LNA) down converter. The ODU is mounted on the spar of
the antenna and is connected via coaxial cables to the IDU and the LNA.
3. Low Noise Amplifier (LNA) Assembly. Consists of a waveguide Transmit
Reject Filter (TRF) and LNA.
C-Band - The ODU accepts a 790 " 11 MHz TXIF signal and transmits it in the 5.925 to
6.425 GHz frequency band. Output power level is controlled by an ALC loop to provide
extremely stable output power regardless of temperature variations.
C-Band - The low noise assembly (LNA) (60#K standard noise temperature) on the OMT
accepts an RF signal in the 3.7 to 4.2 GHz band and amplifies the desired signal to be
received. The ODU down converters converts the signal to an IF of 950 to 1450 MHz.
The Ku-Band satellite terminal system is divided into two areas of operation:
1. SDT-5200 Indoor Unit (IDU). A complete, variable data rate modem, high
stability references, and power supply for the ODU in a 1 RU package.
2. Outdoor Unit (ODU). The ODU is mounted on the antenna feed horn and
directly connected to the OMT. In addition, it also directly interfaces via two
coaxial cables to the IDU.
Ku-Band - The ODU accepts a 790 " 11 MHz TXIF signal and transmits it in the 14.0 to
14.5 GHz frequency band. The maximum available transmit power is +29 dBm (P1dB)
or +34 dBm (P1dB) depending on the option selected. Output power level is controlled
by an ALC loop to provide extremely stable output power regardless of temperature
variations.
Ku-Band - The ODU accepts an RF signal in one of several Ku frequency bands. The
ODU amplifies, then down-converts the signal to an IF of 950 to 1450 MHz. An
integrated transmit band reject filter prevents the integrated low noise amplifier (LNA)
from being overloaded.
1.1.2 Additional Features
The system contains the following additional features:
Note: These features are fully described in Appendix A.
!
Fully Accessible System Topology (FAST): EFData’s FAST system allows
immediate implementation of different options through the user’s keypad.
!
Sequential Decoder: The sequential decoder is used in Closed Network
applications, typically in Frequency Division Multiple Access (FDMA).
!
Asymmetrical Loop Timing: Asymmetrical loop timing is the same timing
method that is designed into the SDM-650B TROJAN interfaces.
!
INTELSAT Reed-Solomon Operation: The Reed-Solomon Codec works in
conjunction with the interface card to provide concatenated convolutional
encoding and decoding.
!
Automatic Uplink Power Control (AUPC): The AUPC feature works with the
ASYNC option to allow remote communication between a local modem and a
remote modem.
!
Asynchronous Channel Unit Overhead: The asynchronous (ASYNC) interface
option provides the interface for terrestrial data and single ASYNC overhead
channel.

1.2 Modem Feature Upgrade (FAST)
The SDT-5200 indoor unit (IDU) has a variety of options available as shown in Table
1-2. Options are available through conventional means as well as through EFData’s
FAST system. For detailed description of the FAST feature and all options, refer to
Appendix A.
Note: EFData has included a DEMO Mode in the Utility menu. This feature will allow
the operator to experience any of the FAST options. This feature has a 60-minute time
limit, after which, the unit will return to its previous configuration.

Note: The basic SDT-5200 is shipped with either Sequential or Viterbi decoder.
The ASYNC/AUPC option allows an additional overhead channel to be multiplexed and
demultiplexed from the data carrier. Two mechanisms are provided for automatic uplink
power control (AUPC) within a closed network.
!
One method, which requires the optional ASYNC/AUPC interface card, is used
for control between two links to sustain sufficient transmit power to maintain a
programmed E
!
The second method is used for self-monitoring the carrier from the same uplink
with the local demodulator, requires no additional hardware, and is softwareselectable. This method is appropriate for applications such as paging networks,
where the uplink is transmit-to receive only devices. The self-monitoring AUPC
function is not available when the ASYNC/AUPC interface option is installed.
The IDU interfaces between Single-Channel per Carrier (SCPC) fixed-rate terminal
equipment operating within the following specifications:
at both ends.

The IDU is capable of data rates from 2.4 kbit/s to 4.375 Mbit/s and includes a

Note: The IDU can be configured to add overhead/framing to the data.
Available modulation types include:
!
Bi-Phase Shift Keying (BPSK).
!
Quadrature Phase Shift Keying (QPSK).
An internal channel unit, conforming to IESS-308 and -309 emulation specifications,
provides overhead designated for an Engineering Service Channel (ESC).

and reference for the terminal outdoor unit.
Demodulator – The demodulator converts an IF of 950 to 1450 MHz down to baseband.
Interface – The interface provides a link between the Digital Test Equipment (DTE) and
the modem. Several industry-standard interfaces are available, as well as EFData
proprietary.
Monitor & Control – The M&C uses a microcontroller to control all operational
parameters and monitor system status. The system also reports modem configuration
status, as well as fault status of the modem. A simple command set allows configuration,
control, and retrieval of status information.

3.1 Unpacking
The Satellite Terminal System and manual are packaged in pre-formed, reusable,
cardboard cartons containing foam spacing for maximum shipping protection.
Do not use any cutting tool that will extend more than 1 inch (2.5 cm) into
the container. This can cause damage to the modem.

Unpack the Satellite Terminal System as follows:
1. Cut the tape at the top of the carton indicated by OPEN THIS END.
2. Remove the cardboard/foam space covering the unit.
3. Remove the unit, manual, and power cord from the carton.
4. Save the packing material for storage or reshipment purposes.
5. Inspect the equipment for any possible damage incurred during shipment.
6. Check the equipment against the packing list to ensure the shipment is correct.
