Any optional accessories you have ordered

4.2 Installation Environment

As with any electronic device, the NX4600 should be placed where it will not be subjected to extreme temperatures, humidity, or electromagnetic interference. Specifically, the selected site should meet the following requirements:
The ambient temperature should be between 0 and 50◦C (32 and 122◦F).
The relative humidity should be less than 95 %, non-condensing. Do not install the unit
in areas of high humidity or where there is danger of water ingress.
Surrounding electric devices should comply with the electromagnetic field (EMC) stan­dard IEC 801-3, Level 2 (less than 3 V/m field strength).
The AC power outlet (when applicable) should be within 1.8 meters (6 feet) of the NX4600.
Where appropriate, ensure that this product has an adequate level of lightning protec-
tion. Alternatively, during a lightning storm or if it is left unused and unattended for long periods of time, unplug it from the power supply and disconnect signal cables. This prevents damage to the product due to lightning and power-line surges.

4.3 Equipment installation

The NX4600 is designed for stationary use in a standard 19" rack. When installing please observe the following points:
Route cables safely to avoid them being pinched, crushed or otherwise interfered with. Do not run AC power cables and signal cables in the same duct or conduit.
The NX4600 has all connectors at the rear. When mounting the unit, ensure that the installation allows easy access to the rear of the unit.
The fans contained in this unit are not fitted with dust/insect filters. Pay particular atten­tion to this when considering the environment in which it shall be used.
Make sure that the equipment is adequately ventilated. Do not block the ventilation holes on each side of the NX4600.

4.4 Ventilation

Openings in the cabinet are provided for ventilation to protect it from overheating and ensure reliable operation. The openings must not be blocked or covered. Allow at least 50 mm free air­space each side of the unit.
Warning: Never insert objects of any kind into this equipment through openings as they may touch dangerous voltage points or create shorts that could result in a fire or electric shock. Never spill liquid of any kind on or into the product.
This product should never be placed near or over a radiator or heat register. Do not place in a built-in installation (e.g. a rack) unless proper ventilation is provided in accordance with the device airflow design as depicted in Figure 4.1 .
The NX4600 may be vertically stacked in 19" racks without intermediate ventilation pan­els. In systems with stacked units forced-air cooling may be required to reduce the oper­ating ambient temperature.

20 Installing the Equipment
4.5.1.3 Protective Earth/technical Earth
To achieve protection against earth faults in the installation introduced by connecting signal cables etc., the equipment should always be connected to protective earth. If the mains supply cable is disconnected while signal cables are connected to the equipment, an earth connection should be ensured using the Technical Earth connection terminal on the rear panel of the unit.
Warning: This unit must be correctly earthed through the moulded plug supplied. If the local mains supply does not provide an earth connection do not connect the unit.
Caution: Consult the supply requirements in Appendix B prior to con­necting the unit to the supply.
The unit has a Technical Earth terminal located in the rear panel. Its use is recommended. This is not a protective earth for electrical shock protection; the terminal is provided in order to:
1. Ensure that all equipment chassis fixed in the rack are at the same technical earth poten­tial. To achieve this, connect a wire between the Technical Earth terminal and a suitable point in the rack. To be effective all interconnected units should be earthed this way.
2. Eliminate the migration of stray charges when interconnecting equipment.
Warning: If the terminal screw has to be replaced, use an M4x12mm long pozidrive pan head. Using a longer screw may imply a safety hazard.
4.5.1.4 Connecting to the AC power supply
Warning: Do not overload wall outlets and extension cords as this can
result in fire hazard or electrical shock. The unit is not equipped with an on/off switch. Ensure that the outlet socket is installed near the equipment so that it is easily accessible. Failure to isolate the equipment properly may
cause a safety hazard.

5 Functional Description

The NX4600 Media Gateway is an encoder, decoder and media edge adapter that takes up to three (fixed chassis), or four (modular chassis) baseband SDI video signals, compresses them using H.264/AVC or MPEG-2, and aggregates and transmits the streams over IP/Ethernet. It is also possible to combine encoding and decoding in the same 1RU unit, which increases flexibility and gives a very tight and compact offering for outsidebroadcast production applications (sports, news and other live events) and managed media services.
NX4600 includes Nevion’strademark advanced protectionmechanisms that enable real-time trans­port of professional media over IP networks, as well as built-in monitoring that helps anticipate and correct any issues with the network or transport should they arise.
Nevion Gateways can be configured via an easy-to-use web interface, which also offers extensive built-in monitoring. Supervision and Connection management can be performed via Nevion’s VideoIPath or any 3rd party Network Management System.
This chapter gives a brief description of the inner workings of the NX4600,
Figure blocks are described in more detail in the following sections.

5.2 Monitoring

The Monitoring section provides monitoring of up to hundreds of transport streams on-the-fly. Pa­rameters of the selected transport streams will be monitored and compared against specifications and specific requirements. The values of critical components can be displayed graphically. An extensive set of alarms may be programmed, with different severity levels. The content of selected packets, or groups of packets, may be recorded for examination and/or documentation.
Measurements are made according to the DVB ETR 290 specifications.

5.3 Seamless IP Protection Switching

Seamless IP Protection Switching (SIPS) provides redundancy by protecting the media stream against errors in the IP network, but in a different manner compared to Forward Error Correction (FEC). FEC is designed to protect the stream against single or short burst packet losses, whereas SIPS provides protectionagainst loss of complete data input, for example, due to link or equipment failure.
The main idea of SIPS is to transmit two identical copies of the media stream over separate network paths. At the receiver side, the data from the two incoming streams are combined at packet level to form an error free output data stream.
The combination of diverse path routing and perfect switching provides for the highest possible Quality of Service, effectively minimizing the effects of random packet losses, burst packet losses, losses due to fast reroutes, and link failures.
Figure 5.2 SIPS functional overview
Functional description
SIPS operates on the RTP packet level. The receive module buffers both incoming streams, mediat­ing and selecting the most appropriate packets in what is termed active-active merging for use in de-encapsulation. In this way, if one stream is impaired, good packets are delivered via the other stream and a good output stream can always be reconstructed.
There will be packet loss at the combined stream only when the packet is received on neither of the two IP sources. The data stream resulting from combining the two incoming data streams will then be processed as one RTP packet stream.
Setup
At the transmitter side, the NX4600 allows sending identical copies of the data flow to a user de­fined list of destinations. When several destinations have been configured for transmission, media streams are sent to different IP addresses but the streams are identical down to the RTP layer and are tagged with the same, randomly generated Synchronization Source ID (SSRC). For each des­tination, the physical or logical VLAN network interface, and IP unicast or multicast destination
NX4600 User’s Manual Rev. 1.8.6 (5027) ID: mediagateway
Functional Description 25
addresses are configured. This enables the two data streams to be routed to their respective net­work paths directly at the NX4600 or at the first subsequent network node. See Section 8.10.2.3 for more information on configuring redundant transmission/IP destinations.
At the receiver side SIPS must be enabled and the IP source parameters for IP flow A and B must be configured to receive the media streams from the two diverse network paths. For any fully seamless protection system to function, the dual media feeds presented at the receiver needs to be essentially coherent i.e. the exact same media feed down to the RTP transport layer. When the data streams have an identical SSRC value and data format, they are assumed to be identical and are used for Seamless IP Protection Switching. See Section 8.6.2.3.2 for more info on configuration of SIPS on the receiver.
Delay compensation
As the A and B flows will typically be routed across network links with different delays, it is necessary for the SIPS module to wait for a period after the first signal is received before it starts outputting data, to ensure that the second signal that is received does not need to be written to the buffer after it is read out.
The SIPS Pre-buffer configuration parameter allows this period to be configured to allow the system to be able to compensate for the maximum expected differential latency between the A and B flows, while minimizing the additional delay added to the system.
Launch Delay Offset
If dual redundant network paths for some reason is not available, the Nevion patented technology Launch Delay Offset (LDO) may be employed on the transmitter side.
This feature makes it possible to introduce a delay to one of the transmitted media streams, and thereby introducing a temporal redundancy in the transmission. In this situation burst losses approaching the time delay configured for LDO can be handled by the receiving SIPS engine, even when only one network path is available.
Note that this setup will give protection against long burst losses, but not against complete net­work failure. If there is a need to protect against link failures, LDO should be used together with redundant network paths (routing flow A and B through different network paths).
For information on how to configure LDO, see
Licensing
The SIPS feature requires a licence at the receiving node. No licence is required to configure mul­tiple IP destinations for an output channel on the transmit side.
The LDO feature requires a licence at the transmitting node.
Compatibility
The SIPS feature is fully compatible with and extends the functionality of the SMPTE 2022-7 “Seamless Protection Switching of SMPTE ST 2022 IP Datagrams” standard.

5.4 Management subsystem

The management subsystem is a set of modules that handles all the interfaces to monitor and control the operation of the NX4600.
ID: mediagateway NX4600 User’s Manual Rev. 1.8.6 (5027)
26 Functional Description
The management subsystem communicates with the users, both humans and machines, via the following interfaces:
Front panel and back panel LEDs for status
Graphical user interface via Flash application in WEB browser
SNMP traps on alarms
SNMPv2c Agent
TXP (XML Protocol) to retrieve and set configuration and status
Alarm relays on alarms
Terminal interface either over Telnet or USB interface for debugging
FTP server for direct file system access
The management subsystem communicates with other internal modules to make the unit perform the wanted operations.

5.4.1 Graphical user interface

Operators monitor and control the NX4600 mainly via the Adobe Flash GUI application served from the device’s WEB server. The GUI application is accessed via a WEB browser that commu­nicates with the configuration framework through an HTTP/XML based protocol.
The device exposes extensive status information to the web GUI providing detailed reports and real-time monitoring displays to the device administrator.
All the device configuration parameters available on the NX4600 can be controlled from the web GUI.
5.4.2 Configuration database
The management subsystem processes configuration changes as transactions. All configuration changes made to the device are validated against the current running configuration before com­mitting them to the device. This limits the risks of the administrator implementing changes that may cause down-time on the unit due to incompatible configuration settings.
Configurations can be imported and exported via the GUI. It is possible to clone the entire config­uration of one device to another by exporting the configuration of one device and importing it to another.
Configurations exported via the web GUI are formatted as human readable/modifiable XML files. These files can be viewed or altered using any standard text or XML editor such as Windows Notepad.
To simplify cloning of devices, certain exported parameters within the XML file are tagged as device specific and therefore will be ignored when imported to either the same device or another. These parameters are as follows:

ASI Port mappings

5.4.3 Alarm manager

The NX4600 contains an integrated alarm manager responsible for consistently displaying the alarm status of each individual interface.
“Port Alarms” are alarms bound to a specific input or output port via a port indexing system. The alarm severity for port related alarms can be configured per port level. “Device Alarms” are global to the device and are not bound to any specific port. They do not follow the indexing scheme. These are classified as “System Alarms”.
Alarms are graphically represented in a tree structure optimized for simplified individual viewing and configuration. The “Device Alarm” tree is available from the “Device Info” page. The alarm tree for each port is available on the “Alarms” page for each port.
The alarm manager presents the alarm of highest severity upon the external interfaces of the de­vice. The severity level of each individual alarm can be defined by the administrator. Alarm configuration is covered in greater detail in the “Alarm configuration” section.
SNMP traps are dispatched to registered receivers whenever there is an alarm status change.
The alarm manager keeps a log in non-volatile memory of the latest 100000 alarms that have oc­curred.

5.5 Time synchronisation

The NX4600 contains an internal real-time clock that is used for all internal timestamps. The in­ternal clock is battery backed up in order to continue operating while the unit has no power.
The internal time can be synchronised as follows:
Manual setting.
From NTP server using SNTP protocol.

NX4600. The numbering scheme contains two numbers, where the first is the slot number. The main board has slot number M (for Main board) and the rest are as shown in figure 6.2. The second number is an incrementing number, starting at 1, that increments for each extra addition of the same connector. As an example, the ASI daughter board in slot number 1 would have numbered the four BNC connectors as 1.1-1.4 as shown in figure 6.3. A DVB-S/S2 daughter board with two F-connector antenna inputs and two BNC connectors for ASI test output will have a numbering of 1.1 (first F-connector), 1.1 (first BNC output), 1.2 (second F-connector) and 1.2 (second BNC output). This is shown in figure 6.4.

6.2 ASI inputs

BNC connectors 1 through 4, as shown in figure 6.2 are input ports. Connect the transport stream input signals to be monitored to any of these connectors. The signals connected to the these input ports should be valid DVBor ATSC compliant transport streams accordingto the operational mode of the unit.
Note: that the four slots, numbered 1-4 in figure 6.2 and the cards contained in them (or the lack of card in them) may vary depending on the product configuration ordered from Nevion.

6.3 1PPS input

This coaxial connector (labelled 1PPS/10MHz) is provided in order to enable locking the internal system clock to a universal reference. A standard 1 pulse per second reference signal should be applied, e.g. from a GPS receiver. 1PPS is used for more accurate PCR measurements, and is required for SFN delay monitoring.

6.4 Alarm/Reset interface

The unit is equipped with a 9-pin male D-sub connector to provide alarm information. Two pro­grammable relays are provided. The first relay is always activated on a critical alarm or when the unit is not powered.
The pin-out of the connector is shown in table 6.2.

9. Optional Reset Input / GPI
Note: The Optional Reset Input / GPI is not currently not yet supported in software, but will be supported in a later release.
If a critical (level 6) alarm has been raised, if the unit is not powered or any other programmed condition for relay 1 is satisfied, there will be a connection between pin 6 and pin 7; otherwise, there will be a connection between pin 7 and pin 8.
The optional (additional) relay will follow the same behaviour, except that it can also be pro­grammed to be not activated for a critical (level 6) alarm.
A connection between pin 9 and 5 (or a TTL low on pin 9) will hold the unit in reset if this function has been enabled. The connection must be held for 0.5 seconds in order to activate the reset. This can be used to force a hard reset of the unit from an external control system. This pin can also be used as a general purpose input (GPI).

7 Operating the Equipment

The NX4600 is configured and controlled locally and remotely through a Flash-based Web inter­face. The only application required on the computer to use this interface is a Web browser and the Adobe Flash Player.
Note: Adobe Flash Player 10.0.2 or newer is required to use the Web interface of the NX4600. As a general rule it is recommended to always
use the latest official release of Flash Player. If the Flash Player is not installed on the adminstrator PC, a copy is provided on the CD delivered with the device. Alternatively, the latest Adobe Flash Player can be downloaded free of charge from

7.1 Accessing the graphical user interface

The default IP address of the NX4600 will most probably not be suitable for the network where the unit will operate. Therefore the user should change the IP address of the management interface so that access may be gained from the network.
http://www.adobe.com.
The NX4600 offers several options to alter the user interface IP address; through an Ethernet con­nection or using a USB terminal interface or using a PC application. If your management com­puter allows setting a fixed IP address, change the IP address using the Ethernet option described in Section 7.3.1.
If a static address cannot be configured on your management computer, Section 7.3.2 gives the procedure to initially configure device network parameters (IP, netmask, etc...) using the USB terminal interface.
Configuring the device functionality according to operational needs is done using the Web inter­face, see Chapter 8.

The screen-shot in Figure 7.1 shows how to configure the network interface in Windows 7 to communicate with the NX4600 via Ethernet M.1 with factory default settings. The IP address/netmask is set to 10.0.0.20/255.255.255.0 which is on the same subnet as the NX4600, and does not conflict with the IP address of the device.
Figure 7.1 Setting static IP address 10.0.0.20 in Windows 7
Note: If several new devices are accessed one after the other, the ARP cache of the computer from which the devices are being accessed may
have to be flushed between each new device access, since the same IP address will be used for different MAC addresses. On Windows 7 this is done on the command line typing the command ’arp -d *’

7.3.2 Changing the management port IP address via the terminal interface

If a static IP address cannot be configured on your computer, follow the procedure below to con­figure the IP address via the terminal interface.
1. Install the USB driver from the product CD. (This step may be omitted if the driver has already been installed.)
2. Connect your computer to the NX4600 via a USB cable to the USB port.
3. Access the terminal interface using a suitable terminal program, emulating an ANSI ter­minal, on your PC (e.g. HyperTerminal). The USB will appear as a virtual COM port on your PC. No specific serial port settings are required. Assure scroll lock is not on. Type <enter> and see that you have a prompt (app>).
4. In the terminal, type the following command and press <Enter>:
ID: mediagateway NX4600 User’s Manual Rev. 1.8.6 (5027)
40 Operating the Equipment
The interface name can be found using the command
ip addr
Using the interface name, an IP address can then be set to an ethernet port using the command
ip addr set <interface num> <IPv4 address>/<Netmask length>
Example:
app>ip addr set 0 10.40.80.100/24
This will result in the IP address 10.40.80.100 being set on Ethernet M.1. The subnet mask is set to
255.255.255.0.
Note: The product CD shipped with the NX4600 contains a USB driver to use for serial communication with the device on the USB port. The
MS Windows driver installation script is configured to give a one-to-one relationship between the physical USB port number on the PC and the COM port number to use on the PC.

7.3.3 Changing the IP address via the display

In order to access the IP interface menu using the display, choose the Network item and press Enter. Under the IP interface menu items; Eth M.1 to M.4, the two choices are: IP Edit and En-
able/Disable.
IP Edit allows the user to set the IP address of the ethernet interface and the subnet mask. The IP address / subnet mask is shown in the following form:
010.040.080.100/24
In order to change the IP address or the subnet mask, the left and right keys are used to move a blinking cursor along the digits and select the ones which need to be altered. Using the up and down arrows increments or decrements the digit that is currently selected.
The Enable/Disable option will enter into a confirmation page where the user can press Enter to enable or disable the selected interface.

7.3.4 Changing the IP address via Detect

Nevion has made a free to use PC application called Nevion Detect that may be used to configure the IP address of the unit. Simplest way to use this application is to connect back to back to the ethernet interface that you would like to change the IP address of, and launch the application. This tool will also detect the current IP address of the interface. Contact Nevion Support to get the application or download it from our webpage.

8.2 Status header

After successful login the start page is shown. The top part of the page (shown in Figure 8.3) is called the status header, while the bottom part of the page (shown in Figure 8.4) is called the status footer.
Figure 8.3 The status header
Figure 8.4 The status footer
In the status header the product name is shown on the left hand side, along with the configurable product label, see Section 8.4.1.
The status header displays an alarm indicator showing the overall alarm status of the device. The colour of the indicator shows the highest level alarm currently active in the unit. It is green if no alarm is active. Other possible colours are described in Appendix D.
Several items are presented in the right corner/section of the header. Starting from the left:
A text showing the current user name.
A button to log out from the GUI.
A button to switch current user level.
The Nevion logo.
A button for minimising the header. Using this hides a lot of the header information and
gives more space for the rest of the page.
In the status footer the following items are present from left to right.
The current software version
The name of the current configuration, if any. See Section 8.4.1 for details on how to
configure this.
The local device time.
An activity indicator.
Note: The activity indicator shows one box for each request being processed by the unit. Each box may change from green to red if ex-
cessive time elapses during the processing. During normal operation, no squares should turn red. If squares start turning red there might be a problem with the communication between the device and the computer, or the device may be busy. If the device has not responded to a request within 20 seconds, the indicator turns yellow. If no response has been received after 40 seconds, it turns red.

Figure 8.11 Alarm log
Each row provides additional information via a tool-tip shown when hovering the cursor over the row. The tool-tip entries are:
Sequence #
A number identifying this specific alarm instance. This number is incremented each time an alarm condition is raised.
SubID 1
The primary numerical index of the alarm instance. This index is reserved for future use and is always set to 1 in the NX4600.
SubID 2
The secondary numerical index of the alarm instance. When the alarm is of type Port alarm this index contains the port number for which the alarm was raised. Other types of alarms may use this index to identify a sub module, but normally it is set to 0.
SubID 3
The tertiary numerical index of the alarm instance. The use of SubID 3 depends on the type of alarm. Some of the Port type alarms use this index to signal the PID value or Service ID for which the alarm was raised. For example, if the CC Error of a PID is raised then the PID value is given by SubID 3.

Product name
Displays the name of the product as designated by Nevion.
Full serial number
The serial number of the device.
Software version
The version of the software currently installed on the device. The software version is given by the following syntax:
<major_version>.<minor_version>.<patch_version>
The convention for the SW version numbering is as follows:
major_version
Incremented for significant SW changes.
minor_version
Incremented for minor changes. The minor version number is even for official retail releases and odd for beta releases.
patch_version
If minor_version is even, patch_version gives the patch level of that version. A patch level of zero means the SW is built on the latest code base, an even patch_version means this is a released SW patch on a previous release. An odd patch_version means that this is a test version. If minor is odd, this is a beta version, and the patch_version simply gives the build number.
Software build time
Reports the time of which the current release image was built.
GUI build time
Reports the time of which the current user interface was built.
Unit up time
The amount of time that has passed since the device was last reset.

8.4.7.1.2 Load Configuration From file
The Load Configuration From File field of the page provides a mean to directly import a file­based configuration snapshot as the new running configuration. All options from the snapshot are loaded and verified before making them active, thereby minimizing the risk of errors in the file that would render the device in a non-operational state.
Clicking the button marked Browse prompts the administrator with a standard system File Open dialogue allowing the administrator to select the file of his choice to import. Once selected, clicking
Load Config performs the following actions :
Transfers the configuration snapshot from the administrator’s PC to the device.
Validates the configuration to make sure that all the options in the file are compatible with
each other and with the device itself.
Presents the user with additional information, such as skipped options.
Activates the configuration.
When an import has been successfully completed the progress bar color turns green and changes its text to OK. Upon failure at any point the progress bar will turn red, and details of the reason for the failure will be presented as messages in the Result of last config activation list.
By default, options specific to the device, including device name and management port network configuration, are disregarded during the import process. This is a convenience feature allowing configurations to be easily moved from one device to another. It also makes management easier in that the Web UI will continue to communicate with the device after a new configuration has been loaded. The default behavior can be changed with the load options, please see Section 8.4.7.1.3 for a description of the options.
Partial configuration files are supported to allow a subset of configuration options to be changed instead of the entire unit configuration. Partial configuration files are validated as differences from the current running configuration upon import before being made active.
8.4.7.1.3 Load options
These options are used to modify the behavior on configuration loading. The options are available when loading from a file (Section 8.4.7.1.2) .
Default action
This parameter modifies the algorithm used when modifying lists (collections) in the config­uration.
Restore
Modify list to contain exactly the entries specified in the file loaded.
Merge
List entries that are present in the running configuration but not in the file loaded are left in the list. New entries specified in the file loaded but not in the current configuration are added. Entries present both in file loaded and in running config are modified.

The network overview shows the list of ethernet ports on the unit. As shown in figure 8.31, it gives some status of the different ethernet ports, like the IP address or host name, the link speed of the port, whether in duplex mode and the current TX and RX bitrates.
8.5.1.1 IP Routes
Figure 8.33 Routing page for NX4600.
The IP Routes page allows the user to configure the IP routing table for the device. The routes configured in this table will be used when routing outgoing IP traffic from the device.
8.5.1.1.1 Adding a new IP route
Note: To configure a default gateway for the device, see Section
8.5.1.1.4.
To add a new IP route, press the Add Route button shown in 8.33. A new line will appear in the table where the following parameters may be configured:
Destination
The destination IP network/host address to use for matching against this routing rule.
Netmask
The subnet mask to use for matching against this routing rule. You may configure either a x.x.x.x style network mask, or alternatively just specify the prefix length of the network mask
NX4600 User’s Manual Rev. 1.8.6 (5027) ID: mediagateway
WEB Interface 71
(number of leading 1s). Specifying the mask 255.255.255.255/32 will give a host specific route that will only match the exact host IP address configured as Destination.
Gateway
The IP of the IP router/gateway that should be used for forwarding IP packets matching this routing rule. The gateway address MUST be a locally reachable IP address, matching the IP subnet configured on one of the local interfaces on the device.
Metric
The metric associated to the routing rule. If a destination address matches more than one routing rule that has the same Netmask length, the rule with the lowest metric will be used.
Two additional colums give additional status information about the routes:
Valid
A GREEN virtual led indicates that this route is currently active. A RED virtual led indicates that this route is conflicting with other IP parameters configured on the device, and is not currently active.
Interface
Indicates on which interface outgoing packets matching this routing rule will be output. The interface is found by matching the rule’s Gateway address against the IP subnets configured on the local interfaces.
All newly added routes will appear in the table with a yellow background color which indicates that this is a new route that has not yet been applied to the running device configuration. Repeat the process above to add multiple routes at the same time.
8.5.1.1.2 Removing an existing IP route
To remove an existing route entry, select the entry in the table, and press the Remove Route button at the bottom of the page. The entry’s background color will change to red, indicating that the entry has been scheduled for deletion.
8.5.1.1.3 Applying IP routing changes
To apply all changes in the routing table press the Apply button at the bottom of the page. This will commit the new routing table to the system and from this point the new configuration will be used for all outgoing IP traffic.
8.5.1.1.4 Configuring a default gateway for the device
The default IP gateway on a device is the router which is used if outgoing IP traffic is not destined to any of the networks configured on the local interfaces, or does not match any of the network specific IP routes configured in the device routing table.
There can only be ONE SINGLE default gateway configured in the device at any time - hence the name “default”.
ID: mediagateway NX4600 User’s Manual Rev. 1.8.6 (5027)
72 WEB Interface
To add a default gateway routing entry to the routing table, press the Add Route button, and enter parameters like this:
Destination: 0.0.0.0 Netmask: 0.0.0.0/0 Gateway: <Default GW address> Metric: 0
Note about the Metric parameter
Note that the only way a route will be deactivated is by disabling the destination interface of the route - a link down event will not alter the routing table.
This means that if multiple routes have the same Destination and Netmask, but different Gate­way/Interface and Metric values, only the route with the lowest metric will be used as long as all interfaces are enabled.
Note about IP data output Manual destination interface option
If the Manual interface option has been selected on an IP data output channel, the data stream will be sent directly to the destination IP address as long as this is either an IP address matching the IP subnet configured on the interface, or is an IP multicast address.
If a unicast destination address is used which does not match the local IP subnet configured on the interface, the stream is directed to the gateway that has been configured as the Data gateway on the specific destination interface. See Section 8.5.2.1 for more about configuration of Data gateway on an interface.
8.5.1.2 IP Ping

Section 8.10.2.3.3).
8.5.1.3 IP Snooper
The IP snooper is a helpful tool to detect existing transport streams on a link connected to the port. The user interface for the IP snooper is shown in figure 8.35. By simply pressing the tick box entitled Enable detection of IP streams, and then the Apply button, any incoming streams on IP will show up in the table below the tick box, if any are detected. It is recommended to only have this feature enabled while configuring this unit, as the IP snooping feature is quite resource intensive.
The IP snooper will show any multicast or unicast streams available at any of the Ethernet in­terfaces. Note that streams will not be detected on the Ethernet interface unless other network equipment forwards these streams to the NX4600.

S/S2
This tab is present only if the input selected in the navigator is an DVB-S/S2 input. It gives access to the satellite specific features. These features at specifically described in Section
8.6.2.9.
PIDs
This page gives detailed information about the currently present PIDs.
Services
This page gives detailed information about the services that are currently running and the components of those services.
Tables
This page shows which tables are present on the input and allows selecting tables that should be analysed by the unit.
PCR
This page shows the PCR PIDs present on the transport stream and information about them. In addition you can analyse PCR jitter on any of the PCR PIDs.
Packet Dump
This page offers dumping of a sequence of TS packets with a selected PID.
In all sub-pages, for a selected input, the list of the current alarms for that input is shown at the bottom of the page. The list is identical to the list displayed in the Current Status view, described in
Section 8.3.1.
8.6.2.1 Main
The content of the Main tab depend on what sort of input is selected (ASI, IP,...).
8.6.2.1.1 Main (ASI input)
The Main page is divided into a various number of sections depending on the type of the input.
Exampled here is an ASI input with its main tab. The main tab for ASI , DVB-S/S2 and IP inputs will look different in terms of the fields describing configurations and status for the various inputs.
The main tab for IP inputs specifically is described in Section 8.6.2.1.2 and the main page for DVB­S/S2 inputs is described in Section 8.6.2.1.3 .
Looking at the input exampled in figure 8.51 the first field is the ASI Configuration. This contains the configuration parameters which are common for all input types (while IP and RF inputs might have some extra as well):
Enable
This shows whether the input is currently enabled. The input is enabled or disabled by click­ing the check box and then Apply.
Label
This is the user defined name of the input port, which can be changed by typing a new label and hitting Apply. It is only used in the WEB GUI to identify the port.

Advanced monitoring
Turns on advanced monitoring of the input, if available. If available and applied, this brings up the Templates, PCR and Packet Dump tabs on the input header shown in figure 8.50.
For ASI inputs, the ASI InputStatus field also gives some basic status for the input. Theses status parameters are:
Signal present - yes or no.
Packet length - 188 or 204 bytes.
Transmission format - burst or spread mode.
The Transport Stream Details field contains information and some configuration parameters con­cerning the transport stream:
TS id
The transport id of the transport stream currently received on the input. The value of this depends on PAT being present and decoded on the input.
Original Network Id
The Original network id of the transport stream currently received on the input. The value of this parameter depends on the SDT actual being present and decoded on the input.

Effective rate
The effective bitrate (excluding null packets) of the transport stream currently received on the input in Mbit/s.
Total rate
The total bitrate of the transport stream currently received on the input in Mbit/s.
The Transport Stream Details section shows all the PIDs that are present on the selected input. The number in parentheses is the total number of PIDs present. A PCR PID is represented by a number shown in italics. A colored PID number provides additional PID status information:
Red
A continuity counter (CC) error alarm is raised.
Blue
Stream is scrambled. The shade of blue represents whether the scrambling mode is odd or even.
Hovering the mouse pointer over a PID provides detailed information about that PID.
On the right hand side of the page is the Services Present section. This shows a list of all the services that are currently present on the selected input. The list depends on PAT and PMT being present and successfully decoded on the input. The service name depends on SDT actual being present and decoded. The number in parentheses is the total number of services present.
The list has three columns:
Service ID
The program number/service id of the service.
Service Name
The name of the service as conveyed by the SDT Actual table. If there is no SDT Actual table or if the SDT table is not analysed, the name is displayed as Service <SID>.
The icon prefixing the service name indicates the alarm status of the service and, if the SDT table is analysed, the type of service. A list of active alarms (if any) on the service is displayed by holding the mouse pointer over this icon.
Detailed information about the service is displayed by holding the mouse pointer over the
"I" icon to the right.
Bitrate [Mbit/s]
The current bitrate of the service, i.e. the aggregate bitrate of all the service components.
Double clicking on a service will navigate to the Services page, with the folder for the service at hand being expanded.
The Generate SLA button at the bottom of the page will generate an SLA report for the current
input, as described more in Section 8.6.2.2.2.

This option contains a checkbox to whether or not the user wants to join a multicast stream. If this is checked, there is an IP field to input the multicast group address. If the box is not checked, the input is configured for unicast reception. This field might have an icon next to it if additional configuration options are used. See
Section 8.6.2.3.
Source interface
A dropdown menu which allows the user to specify which Ethernet interface the incoming IP stream is being received on.
The IP RX Status section presents some information about the IP data received:
TS framing
The number of bytes per TS packet on the incoming transport stream (either 188 or 204 bytes) followed by the number of TS packets being received per IP frame.
RTP sequence errors
A counter showing the number of RTP sequence errors caused by lost packets or packets received out of order. A value of zero indicates that all packets are received in correct se­quence.
Lost RTP frames
A counter showing the number of RTP frames that have been lost, i.e. lost and not corrected by the unit.
Last IP source
The IP address of the transmitter.

Satellite
This allows the user to specify which satellite to tune to. It can either be typed in manually, with satellite orbital position, or chosen from pre-defined satellite in a helper list.
Tune frequency
This allows the user to specify the frequency of the input signal. A helper list is available based on the satellite chosen. All pre-defined satellites yields a pre-defined list of tranponder frequencies for that satellite. Frequency can also be inputted manually.
Polarization
This allows the user to specify which polarization the LNB should use to receive. Available options are vertical (normally done by sending a 13V signal to the LNB) and horizontal (nor­mally done by sending an 18V signal to the LNB).
Auto symbol rate
This allows the user to choose whether to let the tuner do an automatic search without know­ing the symbol rate, or if the symbol rate should be specified and searched for specifically. If this box is ticked, the next setting is disabled. If this box is not ticket, a valid symbol rate shall be input in the next setting. If the symbol rate of the signal is known, it is recommended to not tick this box, and instead input the symbol rate in the next setting.
Symbol rate
If Auto symbol rate is not ticket, this allows the user to specify the symbol rate of the RF signal to be received.
The second RF specific section is the “DVB-S/S2 Status”. This section shows signal status for the actual RF input:
Locked
This indicates if there is a lock on the input signal.
Modulation format
This is the modulation format of the received signal when there is lock.
Symbol rate
The currently measured symbol rate of the incoming signal in kBds.
Transponder frequency
The current transponder frequency. This will be dependent on the LNB-specific settings (see
Section 8.6.2.9.2).
Intermediate frequency
This field is the measured L-band frequency of the signal.
Rolloff
Spectrum rolloff factor of the currently received signal.
Power
Indicates the current signal power of the received signal.

WEB Interface 97
C/N margin
Shows how much the current C/N is above the specifications required C/N to lock to the signal.
AGC level
This bar indicates what level the automatic gain control is at for the current signal. If this is at a maximum, it means there is no signal, or a very weak signal. If it is a minimum, the signal is too strong.
Spectral inversion
Indicates whether the spectrum of the received signal is non-inverted or inverted. Non­inverted is generally the case for signals coming from a C-Band LNB.
Pre-Viterbi BER/PER
The bit error ratio of the signal before error correction.
Post-Viterbi BER/PER
The bit error ratio of the signal after error correction.
MER
This field indicates the modulation error rate of the received signal.
Uncorrectable blocks
The number of uncorrectable blocks in the last output frame.
LDPC iterations
Number of iterations performed by the LDPC.
LDPC error counter
Number of errors in the LDPC counter.
8.6.2.2 Alarms
The Alarms page lets the user configure and view the status of all alarms belonging to the selected input. The page has three or more tabs at the top, depending on the type of input. For ASI inputs, there are three tabs, TS Alarms, Alarm Log, and Searchable log, which are present for all inputs. Inputs with extra alarms, such as IP or RF inputs will have an extra tab for configuring the alarm tree for that particular type.
8.6.2.2.1 TS alarms

Alarm node
Shows the title description of the alarm itself. These have a coloured indicator showing the alarms current status. On the right side of each alarm node, there is an information icon.
By doing a mouseover on the information icon for any alarm node, an alarm details box shows up which gives some extra details for the alarm. The alarm details section includes the following information and buttons.
Alarm ID
The internal ID of the selected alarm. A complete list of alarms is found in Table
D.3.
Alarm
Name of the alarm.
Description
A short description of the alarm.
The other columns on the Alarms page, which are configurable are as follows:
Severity
Overrides the default severity for the given alarm. The default severity is in brackets to the right of the drop down list. De-ticking the checkbox sets the alarm back toits default severity.
Log
If this is de-selected, any alarm entries of this type will not be added to the alarm log. This is selected for all alarms by default, so all entries are logged.
Send trap
If this is de-selected, any alarm entries of this type will not sent as an SNMP trap. This is selected for all alarms by default, so all entries are sent as traps.
Limits
This column consists of zero to three fields, depending on the alarm definition. These limits can be threshold values for a certain parameter, where an alarm will be triggered if these limits are breached. The default value is shown in the greyed out text box next to a tick box. To go back to default value after having configured a different value, simply untick the box.
The Off time is a configurable field for a high number of alarms. Its function is different from the other limit alarms:
Off time
This field is shown for alarms that are automatically turned off after some time when no new errors are encountered. The time to wait from detecting the last error until the alarm is cleared is determined by the value in the box. This may be changed as required. The default value is shown to the right.
ID: mediagateway NX4600 User’s Manual Rev. 1.8.6 (5027)
100 WEB Interface
Note: Configuring a short Off time means that the alarm can be turned on and off at a fast rate, adding an entry in the alarm log every time.
This could result in unintentional filling of the alarm log for certain error conditions. On the other hand, configuring a shorter Off time means that the alarm will stay on for a shorter time in the event of a short duration alarm condition.
Figure 8.57 Alarm severity per sub-ID (typically Service or PID)
For certain alarms related to PIDs, the button at the bottom of the screen called Add PID Override will become active. Pressing this button brings up a dialog box where the user can enter a PID. When pressing Apply, a new line is added below the alarm the PID override is added to. This is shown in Figure 8.57. This allows the user to configure alarms differently based on the PID value.
8.6.2.2.2 Alarm Log and SLA
In the alarm log tab, the user can view the alarms belonging to the particular input. The alarm log tab essentially is as described in Section 8.3.6, with the only difference being that all entries not belonging to that particular input are filtered out.
From this page, the user can press the Generate SLA button (also available in the Main tab) to generate a Service Level Agreement (SLA) report.
The Service Level Agreement monitoring page is accessed by pressing the Generate SLA button which exists on the main page for every input. Additionally, the button exists on the alarm log page for each input, and on the alarm log page for the NX4600 as a whole.
Pressing the Generate SLA button brings up a window showing the SLA generated from the alarm log, which can be presented in a number of ways. These visualizations include:
