This section provides a short description of the minimum steps that must be taken in order to start
operating the TNS544.
If you are an experienced user of Nevion equipment or similar types of TS switching equipment
the following description should enable you to quickly install the TNS544 TSoIP Switch and start
operation. If this is your first time to install such equipment you are strongly adviced to read the
full installation procedure. To gain full benefit of the product functionality and capabilities refer
to the user interface description.
The procedures outlined below are based on the assumption that the unit is in the factory default
state.
4.1 Configure the management interface
Since the TNS544 is all Web controlled the first step is to set up the IP address for the management
interface.
Changing the default IP address using the Web interface requires that yourmanagement computer
may be configured with a static IP address. If a static IP address cannot be configured on your
computer the IP address may be configured via the terminal interface. The procedure is described
in the user manual, refer to section 8.3.2.
Note: Avoid connecting through a network at this stage, as this may give
unpredictable results due to possible IP address conflict.
1. Connect an Ethernet cable directly between the PC and the Ethernet Control port of the
TNS544. The default IP address of the TNS544 is 10.0.0.10/255.255.255.0. Configure the
PC to be on the same subnet as the TNS544.
2. Open your Web browser and type http://10.0.0.10 in the address field of the browser.
Log into the GUI with username admin and password salvador.
3. Browse to Device Info > Network > Control in the GUI, and set the IP address settings
required for your network. Click Apply to activate the new parameters.
4. The connection with your management PC will now be lost. To re-connect to the TNS544
connect both the “Control” port of the unit and the management PC to the network. The
IP settings of the management PC must now be set to agree with the network used.
5. Again, open your Web browser and type http: (New-IP-Address) in the address field of the
browser. Log into the GUI with username admin and password salvador.
1. Assign a name for the device in order to more easily identify the unit in the network.
Browse to Device Info > Product Info and enter a Name and Inventory ID. Click Apply to
activate.
2. Set date and time of the real time clock to ensure correct time stamping of the alarm log
entries. Browse to Device Info > Time Settings. The internal clock may be used to time
stamp alarm log entries, in which case a manual Date and Time adjust is all that is needed.
Click Apply to activate.
You may enable an external time source to provide a common reference for alarm logs of
all units of a system. Refer to the user manual for details.
4.3 Configure operation
A TNS544 can be configured with up to 4 switches. A Switch may be sourced from up to 4 inputs,
IP and/or ASI, and the output of the Switch may be routed to one or several IP outputs or ASI
outputs. Transport streams received on IP are de-encapsulated in to TS packets and the switching
occurs on TS level. After switching, the output of the Switch is appropriately encapsulated before
being sent to an IP output interface. The TNS544 operation does not distinguish between single
program and multi program transport streams.
4.3.1 Enabling IP inputs

The TNS544 is designed to perform seamless switching of MPEG-2 Transport Streams TS, where
the input may be IP and/or ASI. Seamless switching is supported when using identical input
transport streams. Identical input transport streams have the exact same TS packets at the same
packet locations in the stream.
The product offers an easy-to use WEB based user interface giving access to all configuration settings and monitoring results. The TNS544 may be integrated with network management systems
via the SNMP interface.
This chapter gives a brief description of the inner workings of the TNS544, to give a better understanding of how the product works, how you use it and what you can use it for.
Figure
6.1 shows a functional block diagram of the main components inside TNS544. The different
blocks are described in more detail in the following sections.
Each input is fed to a user specified seamless switch. The switch will match the streams and group
them into matching groups. In case of sync loss on one of the input streams, the TNS544 will switch
to one of the other inputs in a seamless way, causing no glitch or other errors at the output.
In case of higher level errors (content errors), a high level sophisticated switch logic takes care of
the switching. Any kind of detectable alarm for an input may be used as switch criteria.
At any time, an operator may switch from the current selected IP stream on a switch to a different
IP stream on the same switch. This on-demand switching will also be seamless.
Note: Seamless switching is only possible when the two incoming streams
are identical. In case the streams are from different sources, switching will
be done on a TS packet boundary to at least avoid sync loss at the output.
6.1 Input and output
The input interface includes two seperate ethernet ports and one SFP socket that can be used to
receive or transmit MPEG-2 Transport Streams over IP. However, only two of the three interfaces
may be active at any one time. One of the Ethernet inputs may be substituted for a SFP module
giving the option to provide input via e.g. optical fibre. Use of a SFP module is user configurable,
provided this software option has been licensed.
Figure 6.2 gives a detailed overview of how the input and output interfaces are related and how
they are connected to the seamless switches.
If the unit is equipped with ASI connectors, the are 8 ASI connectors, which consists of 4 pairs
with one input and one ouput. Each output has a controllable relay which let’s the user select if
the output TS should come from the corresponding input or from any of the switches. On power
loss the ASI relay will fall back to it’s upper position, i.e. each output is wired to it’s corresponding
input. On power loss there will be no IP output. All ASI output ports should be terminated with
a 75 ohms termination, or by connected to another equipment.
These are the following capabilities of the TNS544 TSoIP Switch:
• The TNS544 may have from 1 to 4 switches, where the number of switches is a licenced
feature (SSWX).
• All inputs may be routed to any of the switches, but an input may not be routed to more
than one switch simultaneously.
• A switch may have from 1 to 4 inputs, where each input may be ASI or IP or a combination
of ASI and IP inputs.
• Each switch may have up to 8 IP output copies, and up to 4 ASI output copies. In total
there are 4 ASI output ports shared among the switches.
• All IP inputs and IP outputs may use any VLAN on any of the Ethernet/SFP interfaces.
• An ASI output may only used as an output of the same switch as it’s corresponding input.
If however the corresponding input is not used as a switch source, the output may be used
as an output of any switch.
6.1.1 Protocol mapping
Figure 6.3 Protocol mapping
When transmitting TS streams over IP, the protocol mapping is according to figure 6.3. The VLAN
framing and RTP encapsulation are optional.
The RTP layer is important for diagnosing network related problems, since it contains a sequence
number that can be used for packet loss detection.
The maximum transfer unit (MTU) for Ethernet is usually 1500 bytes. This limits the number of
transport stream packets to embed into the outgoing Ethernet/IP frames to be between 1 and 7.
6.2 Management subsystem
The management subsystem is a set of modules that handles all the interfaces to monitor and
control the operation of the TNS544.
The management subsystem communicates with the users, both humans and machines, via the
following interfaces:
• 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
• SNTP client for real time clock synchronisation
• 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.
6.2.1 Graphical user interface
Operators monitor and control the TNS544 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 TNS544 can be controlled from the web
GUI.
6.2.2 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:
