Introduction
User Manual for AZ430 WAN Satellite Modem
1 INTRODUCTION
1.1 Short Description
The AZ430 is a state-of-the-art satellite modem designed for applications where two parts of a Wide Area Network (WAN) are connected over satellite using routers with HSSI interfaces.
The AZ430 interfaces directly with terrestrial routers through an HSSI interface with bit rates up to 52 Mbit/s (standard HSSI) or 110 Mbit/s (extended HSSI).
This modem is fully compatible with DVB-S and DVB-S2 standards and provides exceptional performance and bandwidth efficiency.
At the output of the modulator, the signal is available on an L-band interface. IF band as well as HPA control functions are available as configuration options. When activated, the unique linear and non- linear predistortion option Equalink™ provides an additional link margin improvement of up to 2,5dB.
On the receive side, the AZ430 has a dual L-band input (950-2150 MHz). The active input is selected by the user and can provide DC power and frequency band selection signals compatible with most professional and commercial LNBs. An adaptive equalizer compensates linear distortion of the transmission channel.
The integrated Noise & Distortion Estimator (NoDE) tool provides an accurate reading of the satellite link margin even in presence of non-linear distortion and allows the user to find the optimum input back-off setting very easily for 16APSK or 32APSK operation, whether or not non-linear predistortion is applied .

10.0 MHz Reference Input
This input is used when you need a reference with enhanced stability or when you need several devices to be synchronised to the same clock source. The level should be 0 dBm nominally. The 10.0 MHz reference input will only be available if this option is installed.
Ethernet Connection
A standard RJ-45 connector provides connection to an Ethernet hub in a LAN (10/100BaseT). You can set the IP address and subnet mask from the front panel. The default IP address is: 10.0.0.1.
You can send RMCP (Remote Monitoring and Control Protocol) commands to the modem using the Ethernet interface. The commands are sent as data in a TCP/IP stream. The used socket number is 5933. The RMCP protocol is exactly the same as for the serial interface, with one small exception: the receiving device ignores the RMCP address of the device (that is present in an RMCP command).
All RMCP commands are explained in the reference manual of the AZ430 modem.
A separate general RMCP manual can be obtained via
TechSupport@newtec.eu. This manual explains how
Newtec devices can be remotely monitored and controlled via the serial port or via Ethernet.

4.3 RMCP
4.3.1 Remote Monitor and Control
Remote monitor and control (RMCP) is possible via the serial interface (RS232/485) or through RMCP over Ethernet. The commands are described in the modem Reference Manual.
You can download our RMCP loader tool for free from
www.newtec.eu> Downloads.
The RMCP manual explains how Newtec devices can be remotely monitored and controlled via the serial port or via Ethernet. A copy of a separate general RMCP manual can be obtained via
TechSupport@newtec.eu.
4.3.2 Connecting the Modem
The modem is set to RS485 by factory default. When you prefer RS232, choose:
>> Unit >> Setup >> Serial port settings
Default serial port settings:
/Unit/Setup/Serial port settings:
Serial interface type RS485
Device RMCP address 100
Serial baud rate 115200
Alternatively, use an RS232 to RS485 converter to connect the Monitor and Control port to a serial communication port of a PC. Pin lay-out on the converter can differ depending on the brand and type of the converter.
Check the User Manual of the converter to make an appropriate cable

5 5 GND
Table 3 - RS232 Cable Pin Layout
4.3.3 Serial Interface and Line Settings
The main line settings for this serial interface are:
Asynchronous data transfer
1 start bit (logic "0")
7 data bits (LSB first on line)
Even parity
1 stop bit (logic "1")
4800, 9600, 19200, 38400, 57600 or 115200 baud
To set the serial interface baudrate choose:
> Unit > Setup > Serial port settings.
There is no flow control on the serial interface. Apart from correctly formatted messages, the only significant character here is the SYNC-character (value 16 hex). The device sends this character to indicate that it is busy executing the command and preparing the response. This prevents other devices from taking control of the bus if the response cannot be given immediately.
4.3.4 RMCP over Ethernet
You can send RMCP commands to the device using the Ethernet interface. The commands are sent as data in a TCP/IP stream. The used socket number is
5933.The RMCP protocol is exactly the same as for the serial interface, with one small exception: the receiving device ignores the RMCP address of the device (that is present in an RMCP command).
To enable the device to communicate over Ethernet, the Ethernet interface needs to be configured. See:
>> Unit >> Setup >> Ethernet settings

4.3.5 Protocol
The control unit sends a “request” message to a device identified by its unique address. The addressed device interprets the message, performs the requested action and sends a “response” message back.
The receiving device rejects all messages with transmission errors without any further action. Transmission errors are:
No stop bit
Parity error
LRC-error
Message receive buffer overflow.
The addressed device responds to all correct formatted messages – except for some special system messages – with an acknowledge message. Only in a few restricted cases does the device not respond to a request from the control unit. This is, for example, the case when a general device reset is requested.
Correctly received messages which the device cannot handle are refused via a no­acknowledge “error” message. This message contains the reason why the message is rejected.
A device never sends messages on its own initiative. It only responds to a request from the control unit. The total transmit time of a complete message may not exceed 250 ms. If the message is not completed within this time, it is discarded.
4.4 SNMP
The Newtec MIB allows full monitor and control over the complete device using any SNMP browser (HP-OpenView, NetworkView). We support the basic standard MIB (monitor and control of IP interface, versions of the software …) and above that we have a full proprietary MIB, which contains all the OIDs needed to control the device.
We support traps. These form a mechanism to trigger the NMS when a change in the device has occurred. After receiving the trap the NMS still has to poll the device to find out the details of the change.
The SNMP details can be found in the reference manual of this modem.

6 FEATURES
6.1 The Noise and Distortion Estimator (NoDE)
6.1.1 Introduction
NoDE (Noise & Distortion Estimator) simplifies ground station operation activities and enables an efficient usage of transponders. NoDE is a unique and innovative tool that simplifies ground station operation activities by providing a means to monitor the quality of the satellite link. It performs a continuous and accurate measurement of the noise margin and the amount of non-linear distortion on the received satellite signal. NoDE allows operators to easily fine tune their satellite links to their optimal operational point under any circumstances. Regular fine tuning of the satellite link parameters will increase the efficiency of the transponder and at the same time provide financial benefits.
In addition, NoDE enables the operator to view the linear and non-linear effects from changes in the uplink power. It can help to prevent errors in operations such as the addition of too much power and distortion that could lead to the total loss of the communication links.
NoDE is the perfect tool to provide operators full control over transmission performance when linear and non-linear distortions are present. It enables higher modulation schemes such as 16APSK and 32 APSK and helps operators to get the most out of their transponder.
6.1.2 How does NoDE work
In digital satellite communications the energy per symbol related to the noise power spectral density (Es/No) is an important parameter used to determine the quality of the transmission. The Es/No measurement at the receiver side needs a certain threshold to ensure an error-free transmission.
Figure 14 - PER Vs Es/No

SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
Features
User Manual for AZ430 WAN Satellite Modem
It is commonly accepted that a transmission is considered as error-free when the PER (Packet Error Rate) at the reception side is below 10
-7
. For each DVB-S2
modcod, as shown in
Figure 14, a minimum value (Es/No)
QEF
guarantees quasi
error free transmission.
Figure 15 - LME – Linear Environment
In a linear environment, as described in Figure 15, the Link Margin Estimates (LME) provided with or without NoDE are identical. They correspond with the difference between the channel Es/No and the (Es/no)
QEF
of the corresponding
modcod, which is the real operation margin of the transmission.
Figure 16 - LME – Non-Linear Environment
When non-linear distortion is present, the real link margin is decreased and is no longer equal to the difference between the measured Es/No value and (Es/No)
QEF
. NoDE calculates the amount of distortion present on the received signal, then corrects the minimum ES/No value to obtain quasi error-free transmission by a delta Δ that takes into account the effect of the distortion. In a non-linear environment, as described in
Figure 16, NoDE enables the measurement of an accurate Link Margin Estimation. By providing the operator with an accurate estimation of the Real Link Margin, NoDE prevents the link being operated in a region where the performance is unpredictable and only marginally stable.

6.2 Equalink
BER performance degradation due to transmission channel impairments is becoming increasingly important in DVB-S2 systems operating with higher order modulation formats (16APSK, 32APSK), in particular at the higher symbol rates.
The Equalink concept effectively optimizes satellite link performance by counteracting these effects. Newtec DVB-S2 Modulators equipped with the Equalink™ feature contain both linear and non-linear predistortion functions which can be individually enabled/ disabled.
Equalink operating principle:
Optimum predistortion is computed off-line based on specified distortion
characteristics
Resulting predistortion table(s) are uploaded to the Modulator and activated
Link performance can be expressed in terms of Bit or Packet Error Rate (BER or PER) versus Energy-per-symbol to Noise density ratio (Es/N0).
For a communication channel over a satellite link, the overall link performance can be severely degraded by channel impairments. Examples of such impairments are:
Interference (Adjacent Channel Interference (ACI) and Co-Channel Interference
(CCI)
Inter-Modulation (IM)
Adjacent Satellite Interference (ASI)...)
Phase noise
Signal distortions
• ...
Performance degradation due to these impairments is becoming increasingly important in DVB-S2 systems operating with higher order modulation (16APSK, 32APSK), in particular at the higher symbol rates.
The Equalink™ concept effectively optimises satellite link performance by counteracting these effects.
Newtec DVB-S2 Modems equipped with the Equalink™ feature contain, both linear and non-linear predistortion functions which can be individually enabled /disabled.

6.3 Demodulator Statistics
The demodulator statistics shows a number of monitoring parameters of the received carrier for each stream present in that received carrier in case of DVB-S2.
Figure 17 – Screenshot of the Demodulator Statistics overview.
6.3.1 FEC-rate and mod
This monitoring parameter displays the detected modulation and FEC used for each of the DVB-S2 streams in the received carrier.
6.3.2 Frame type
This monitoring parameter displays the detected frame type (normal or short frames) that is used for each of the DVB-S2 streams in the received carrier.
6.3.3 Pilots
This monitoring parameter displays whether pilot tones were inserted for each of the DVB-S2 streams in the received carrier.
6.3.4 BB frame count
This monitoring parameter displays the number of baseband frames that are decoded by the demodulator board for each of the DVB-S2 streams in the received carrier.
6.3.5 Uncor frame count
This monitoring parameter displays the number of uncorrected baseband frames by the demodulator board for each of the DVB-S2 streams in the received carrier. It indicates that the link margin is too low or that channel distortions caused by saturation or non-linearity caused the decoder not to be able to correctly decode frames.

6.3.6 Channel quality estimation
The channel quality estimation displays the Es/No of the modulated symbols for each of the DVB-S2 streams in the received carrier. It differs from the total carrier Es/No which only looks at the Physical Layer Headers (which are modulated in a kind of BPSK modulation). Hence in a non-linear channel the total carrier Es/No and Channel Quality Estimation will differ because symbols modulated with higher modulation and coding than the headers will suffer more from the degradation due to non-linearity. It is to be noted that the Es/No indication is derived from the number of corrections the LDPC decoder had to perform. Hence it is most accurate close to the threshold of decoding. For high Es/No values the error becomes larger.
6.3.7 C/D est.
Carrier-to-distortion estimation. This value (in dB) is a measure for the distortion due to linear and non-linear degradation that is present in each of the DVB-S2 streams in the received carrier. It can be used to determine the optimal operating point when optimising a (new) satellite link (for example input back off). The operation point should be selected to have the highest C/D value.
6.3.8 C/D clipping
The C/D clipping will indicate “<” or “>” when the C/D value is too low or too high to be accurately determined. In case it is too low, the link margin might be too low in order for the detector to operate correctly. In case it is too high, there might not be enough distortion (for example in perfectly linear operation) in order for the detector to display a meaningful value.
6.3.9 Link margin est.
Link margin estimation for each of the DVB-S2 streams in the received carrier. This monitoring parameter indicates how much the Es/No is above the decoding threshold. It is a measure for the number of dBs of fading that is possible on the link before the demodulator is not able to decode the received signal anymore.
6.3.10 Link margin clipping
The link margin clipping will indicate “<” or “>” when the link margin value is too low or too high to be accurately determined. In case it is too low, the link margin might be too low in order for the detector to operate correctly. In case it is too high, there might not be enough decoding errors (for example in channel with high link margin) in order for the detector to display a meaningful value.

APPENDIX B – USER DEFINED MENU
You can configure the user menu according to your needs. In this way, you can create a quick access to those control, monitor and testing parameters that you need to change or monitor regularly. In addition, you can also change the order in which the menu items are presented to meet your specific demands. This is very useful in, for example, the DSNG applications. Here you can pre-configure the general parameters and store them in the default boot-configuration. You can then make all relevant parameters that need a quick change during link setup available as a group in the user menu. When you have done this, you can operate the WAN Satellite Modem without having to go through all the different menus. A typical example would be to group the parameters output frequency,
output level and
transmit while leaving all other parameters untouched.
