Introduction C5/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.
1–4 Rev. 0
C5/K1/K3 Integrated Satellite Terminal System Introduction
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.

C5/K1/K3 Integrated Satellite Terminal System Introduction

1.3 Modes of Operation

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.
b/N0
!
The IDU is capable of data rates from 2.4 kbit/s to 4.375 Mbit/s and includes a
-9
1 x 10
/day standard internal frequency reference.
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).

Monitor and Control (M&C)
Modulator - The modulator converts the baseband data to a shaped, modulated IF from 779 to 801 MHz. The modulator output also provides the M&C control link, DC power, 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.

1.4.2 C-Band Outdoor Unit (ODU)

The ODU (Figure 1-6) consists of the following assemblies:
!
Power Amplifier
!
Up Converter/Block Down Converter
!
Automatic Level Control
!
Data Link for Fault Sensing and Control
!
Switching Power Converter
!
Radio Frequency Terminal
The ODU is a weatherproof C-Band up converter/transmitter that automatically adjusts for cable losses and changes between the IDU and the ODU. The transmit (TX) power level can be adjusted between +27 to +34 dBm. The ODU interfaces to the IDU using a two coaxial cables. The cables consist of the following signals:
!
Cable No.1
TX signal
$
M&C link
