To access the first interface screen, enter the product’s IP address in the browser’s address bar: http://device_ip_address http://device_ip_address.. 2. To locate the device’s IP address use the front panel or CLI (serial interface) under system configure management  IP parameters  IP address.

1.2 Web Users The Web interface includes three levels of user groups:   

Users – who have permission only to read device variables. Operators – who have permission to both read and write device variables. Administrators Administrators – who have permission to both read and write device variables, as well as higher privileges, such as performing user-related actions.

By default, NovelSat products initialized with one user from each group under the names user, user, oper, and admin accordingly. The password is NovelSat. NovelSat. It is highly recommended to change passwords passwords after a device is initiated. Changing password, or any other user actions, can be done via the user screen under the System menu. User configuration screen contains three buttons to activate three options. When an option is chosen the appropriate fields appear.





Mode: determines the mode of the mode-codes that will be compared. The calculator currently support the following options: DVB-S2, NS3 and DVB-S2+NS3. Frames Size: determines the frame size of the mode-codes that will be compared. The options are: Normal or Short. Pilot: determines the pilot usage of the mode-codes that will be compared. The options are: Yes (with pilots) or No (without pilots). Roll-Off: determined the roll-off of the mode-codes that will be compared. If user has chosen to compare to multiple Line Modes (e.g. DVB-S2+NS3), a specific roll-off will be chosen for each mode. Include Redundant: determined whether to present redundant Mode-Code options. Redundant Mode-Code is defined as options that at least one other Mode-Code with same Line-Mode has a higher Info-Rate and lower CNR.

2. Comparison Reference; in this section user can decide what would be the compared reference for all calculations. He can decide to perform comparison according to CNR, SNR or Mode-Code. Sub fields will appaear according to his choise:

NovelSat MCT Calculator’s Results

When receiving user’s choises, the calculator will present all Mode-Codes that match characters as specified in ‘compared mode codes’ that also meet reference criteria:

-

If Comparison method is according to CNR, Mode-Codes with CNR within the range [reference_cnr – link_margin , reference_cnr] will be shown.

-

If Comparison method is according to SNR, Mode-Codes with SNR within the range [reference_snr – link_margin , reference_snr] will be shown.

-

If Comparison method is according to Mode-Code, Mode-Codes with CNR within the range [reference_mode_code _cnr – link_margin , reference_mode_code_cnr] will be shown.

-

In addition, one more Mode-Codes for each selected Line-Mode, will be shown at each edge of the range.

For each Mode-Code that included in the desired range the calculator shows all the necessary details: link margin, info-rate, cnr, snr, Eb/N0, line mode, modulation, frame size, fec rate, roll off, pilot and symbol rate.

Version 1.2.1 I 26


Example:

Figure 31: MCT Calculator use example

In this example all not redundant Mode-Code that are either DVB-S2, normal frame size, with pilots and with roll -off of 0.2, or NS3, normal frame size, with pilots and with roll-off of 0.05. have been compared to reference Mode-Code of DVB-S2, 16APSK , normal frame size, with pilots, roll-off of 0.2 and 4/5 fec rate. Reference Mode-Code has CNR of 10.548188 and the desired link margin is 1.0, therefore ModeCode that appear are those with CNR within the range of [9.548188 , 10.548188]. In addition the first and last 2 line are extra Mode-Codes that are not included in the previous range, but are the closest to it.  

Advised Mode-Code In addition to present Mode-Codes within the requested range, MCT calculator offers advise regarding what should be the best Mode-Code to be used. The advised Mode-Code is as follow:

Version 1.2.1 I 27


-

-

The lowest Mode-Code within the range, that is not redundant and not higher than cnrlink_margin+0.3, when comparing according to CNR or Mode-Code, or snrlink_margin+0.3 for SNR comparisons. If there is no such Mode-Code, MCT Calculator will advise on the extra Mode-Code that is lower than the range, meaning lower than cnr-link_margin (or snr-link_margin).

Result table legend Results are presented in a table, and colored according to the following criteria:

Figure 32: MCT Calculator legend

Explenations: Reference Mode-Code. Will only appear if user chodes Mode-Code as a comparison method Advised Mode-Code with NS3 line mode. Advised Mode-Code with DVB-S2 line mode. Mode-Codes that are redundant. All other Mode-Codes. Apply specific Mode-Code on device User can easily change current working Mode-Code of device to one of the advised or shown Mode-Codes by simply apressing the “apply” button at the desired Mode-Code row in results’ table.

Figure 33: MCT Calculator result table and apply buttons

Version 1.2.1 I 28


Please note that switching between different Line Modes is a long action, therefore applying Mode-Code with different Line Mode that current, may take some time. Also, when applying specific Mode Code it will affect both channels.

Version 1.2.1 I 29


7 ACM Mode 7.1 What Is The ACM Mode ACM Mode is an Adaptive Coding and Modulation Mode, used to adjust modulation parameters to changing link conditions. It allows using the highest possible modulation with current link status; if link conditions get worst, the system will automatically change modulation in order to avoid loss of data. If link condition is improved, system will automatically change modulation to highest possible modulation. ACM Mode supports multy receivers and changes modulation according to worst among them, therefore if several recieveres listen to same channel and link status of one of them is declining, causing its SNR to decline as well, the transmitter will change Modulation and Code rate to highest possible according to the worst reciever’s condition in order to prevent lost of data in all receivers. NS1000 ACM Mode also support multi-channel mode. Each channel is treated separately to avoid reducing efficiency of receivers that do not receive data from same channel as those who’s link’s conditions deteriorated. For example: if a Transmitter transmits two channels to two different receivers such that one receives only transmission from channel-1, and the second receives only transmission from channel-2. If the link status of the first receiver declines, the transmitter will switch the first channel’s modulation to a lower one, however it will not change the modulation of channel-2. This enables the use of two regions, receivers in region A can receive channel-1 ajjd recovers in region B can receive channel-2. Important! ACM Mode only supports pilots on. Enabling ACM Mode will force both channels to transmit data with pilots.

7.2 Flow Control The transmitter, NS1000, uses Ethernet Flow Control (IEEE 802.3) to regulate the transmit rate of the device (e.g.: Switch, Router) connected to modulator. When using ACM the link bandwidth can decrease if the modulation parameters have changed because the link conditions deteriorated. If that occurs some Ethernet packets could be lost because of the congestion caused by the decreasing bandwidth. Using flow control the modulator can ensure no packet loss when the ACM changes modulation parameters due to changes in the link conditions.

7.3 Communication Between Transmitter and Receiver ACM Mode can work in “point -to-point” mode:

Version 1.2.1 I 31


The return channel from receiver(s) to transmitter is an IP link. Receiver signal the transmitter every few seconds on it status using UDP protocol. These messages are received on transmitter side in port 3000. The transmitter does not sends ACM messages to receiver(s).

7.4 ACM Mode Configuration In order to operate on ACM Mode, both transmitter and receiver(s) need to be configured. NS1000 configuration On NS1000 there is only one configuration parameter need to be configured: ACM Mode Status that can be either enable or disable. To configure ACM Mode: 1. Go to the Line screen under the modulator-configuration menu. 2. Switch ACM Mode to either enable or disable.

Figure 36: NS1000 ACM Mode configuration

While set to ‘disable’, ACM mode will not work and all receiving messages from receivers will be ignored. When set to ‘enable’ the following settings will become read-only fields: Line Mode, Channels Frame Size, Channels Modulation, Channels FEC Rate and Channels Pilot.

Version 1.2.1 I 32


NS2000 configuration On NS2000 there are several configuration parameters to configured. To configure ACM Mode: 1. Go to the Line screen under the demodulator-configuration menu. 2. Switch ACM Mode to either enable or disable. 3. Set ACM Server address (the transmitter). 4. Set ACM Margin. Margin.

Figure 37: NS2000 ACM Mode configuration

7.5 ACM Mode Statistics ACM Mode statistics is available only on NS1000, the transmitter side. To watch ACM statistics statistics and follow changes: Go to the ACM screen under the monitor menu.

Figure 38: NS1000 ACM Monitor Menu Path

ACM Statistics provide user information on which receivers are currently listening to the transmitter and activated ACM Mode. For each receiver displayed the reciving information it sent, such as IP address, current SNR and requested link-margin. The Matching MCT displayes as well, showing the current Mode-Code the transmitter is using for each channel.

Figure 39: MCT Statistics screen

In the example shown in Figure 37, both receivers listem to channel-1, however only one receiver receives channel-2 as well. The first receiver, on IP address 172.26.20.24, has low SNR that causes the transmitter to lower modulation for channel-1, affecting second receiver too. Channel-2 does not received by a lower SNR receiver, thus transmitter chose a high transmission modecode. Note that receivers can receive either both channels or just one of them. The transmitter will change modecode according to lowest received SNR, which can be different between its two channels.

8 Use Cases 8.1 Introduction This chapter describes how to configure the NS2000 Demodulator based on practical configurations for each processing model:  

Single Channel Mode (CCM) with ASI source Dual channel Mode (VCM) with ASI source

8.2 Use Case 1: Single Channel Mode (CCM) with ASI ASI Source 8.2.1 Introduction The NS2000 supports a variety of output interfaces, such as Asynchronous Serial Interface (ASI). ASI is a streaming data format which often carries a MPEG Transport Stream. This use case explains how to setup the system to transport and receive an ASI stream. The NS2000 can also receive streams to other modulators, as long as they are configured with TM matched settings. However, when transmitting using NovelSat’s NS3 technology, it can only be received by NovelSat’s Demodulator. The physical setup is shown in the following illustration.

8.3 Use Case 2: Dual Channel Mode (VCM) with ASI ASI Sources 8.3.1 Introduction The NS2000 supports Dual channels (which enables the use of VCM mode). Each channel can be connected to any of the available Input Interfaces, such as 2xASI, ASI&IP and others . This use case explains how to setup a system to transmit and receive two different ASI streams. A modulator transmits multi-streaming. This stream consists of two different ASI streams, each with a different ISI. The NS2000 Demodulator receives the streams and filters out the first and second ASI streams according to the ISI range. The NS2000 can also receive streams to other modulators, as long as they are configured with TM matched settings. However, when transmitting using NovelSat’s NS3 technology, it can only be received by NovelSat’s Demodulator. The physical setup is shown in the following i llustration.
