Getting Started 17
4 Getting Started
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.

18 Getting Started
4.2 Configure device name and time settings
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
This procedure enables an IP input.
1. Browse to Inputs > Inputs Overview > IP Inputs. At the bottom of the page, click the
Add IP Input button. Click Apply. An entry for the new input appears in the table, with
default values for all parameters.
2. Open the IP input configuration page by clicking on the table entry.
3. In the Main page, IP RX Configuration field, tick the Enable input check box and type an
identifying name, e.g. the service name, in the Input label box. Specify the UDP receive
port. If the signal to receive is an IP multicast click the Join multicast check box and enter
the multicast address in the adjacent field.
4. Select the Ethernet interface from the alternatives in the Source interface pull-down list.
Click Apply to activate.
5. The IP RX Status field will indicate if the attached network cable carries a valid signal
and the remaining status fields will report the properties and contents of the incoming
transport stream.
The coloured indicator at the top of the page shows the overall signal status.

6 Functional Description
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:
ID: um_tsoipswitch TNS544 TSoIP Switch User’s Manual Rev. 2.6.B (5219)
Page 30
30 Functional Description
• 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
• 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:
• Device Name and Inventory ID
TNS544 TSoIP Switch User’s Manual Rev. 2.6.B (5219) ID: um_tsoipswitch
Page 31
Functional Description 31
• IP network parameters
• On-device stored configurations
6.2.3 Alarm manager
The TNS544 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.
Alarm relay 1 and alarm LED are controlled to signal whenever there is a critical alarm present.
Alarm relay 2 is configurable.
The alarm manager keeps a log in non-volatile memory of the latest 10000 alarms that have occurred.
As an additional option, the alarm manager in the TNS544 supports so-called Virtual Alarm Relays.
These are highly programmable items that can be customised to react to virtually any given alarm
event or combination of alarm events. The status of each virtual alarm relay can be viewed in the
GUI and can also be exported using SNMP. Details on configuring the virtual alarm relays can be
found in the WEB interface section.
6.3 Time synchronisation
The TNS544 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 servers using SNTP protocol. Up to four NTP servers can be configured for
NTP server redundancy.
More than one clock source may be specified in a prioritised order. If one source fails the next
priority source will be used.

6.4 The SFP module
The SFP module (SFP = small form-factor pluggable) is a third-party product providing an extra,
optional interface to the TNS544. Depending on the module type it may act as a direct bridge to
E3 and T3 telecom network lines using coaxial cable, or provide a high-speed STM-1/OC-3 optical
interface employing single or multi-mode optical fibre.
Figure 6.4 A
typical SFP module
An SFP module may be configurable or non-configurable. Using a configurable SFP module the
parameters relevant to its operation are controlled through the TNS544 WEB interface. Control
information is passed to and from the SFP module using the I2C protocol.
A wider range of settings are available using the SFP module internal WEB server. To access the
internal WEB server an SFP configuration adapter is required. For further information on this,
and for detailed technical specifications, refer to the vendor’s manual for the specific device.
The TNS544 provides a slot to accommodate an SFP module. Access to the SFP interface is possible
if the SFP software is installed and the feature key has been licensed (see Section 9.4.7).
The SFP interface must be expressly enabled from the TNS544 user interface (Device Info > Maintenance > General) by selecting SFP from the Electrical/SFP dropdown menu and hitting Apply
After rebooting, the user interface will reflect the presence of the SFP network interface. This is
managed the same way as other network interfaces, but with an extra WEB page tab to support
SFP specific functionality.

is also possible to force a passive connection for each relay while power is connected, see chapter
9.6.2.1 for details on how to do this.
For physical specification of the ASI ports, please refer to Appendix B: Technical Specification.
7.1.1 ASI input ports
Inputs signals connected to the ASI ports should be a DVB or ATSC compliant transport streams,
depending on the selected setting (see Section 9.4.7.1 and 9.5.2.1).
7.1.2 ASI output ports
The ASI port ouputs a DVB compliant transport stream. When no stream can be supplied the
output will be idle characters, only. If a stream is supplied the output will be a combination of
MPEG-2 transport stream data bytes and idle characters.
7.2 1 PPS Input
An optional interface module provides an input connector for a 1 PPS synchronisation signal for
the internal system clock. Connecting an 1 PPS signal will reduce potential output jitter.
The signal is:
• 1 PPS. 50 Ω TTL input for a 1 pulse-per-second signal.
For physical parameters of the 1 PPS port, see appendix B.6.1.

Physical Description 35
7.3 Ethernet data ports
Two Ethernet ports are provided for data transmission. The default port setting is auto sense between 10, 100 and 1000 Mbit/s. The operator is able to force the interface speed to fixed 100 Mbit/s
or fixed 1000 Mbit/s. This is useful to minimize the synchronisation time when reconnecting signal cables.
For flexibility, the TNS544 provides an optional SFP (Small Form-Factor Pluggable) slot to accommodate a copper or optical interface SFP, allowing customers to use different SFPs for special distance, cost, existing infrastructure and future expansion requirements. The TNS544 is prepared
for electrical (1000Base-T) or optical 1000BASE-SX and 1000BASE-LX SFP transceivers. When the
SFP module is in use Ethernet port Data2 is no longer available.
The LEDs for the electrical Ethernet data port are used as follows:

Operating the Equipment 39
8 Operating the Equipment
The TNS544 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 9.0 or newer is required to use the Web interface
of the TNS544. As a general rule it is recommended to always use the
latest official release of Flash Player (version 10 or newer). 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
Note: When using Microsoft Internet Explorer, version 6.0 or higher is
required. It is however recommended to upgrade to version 8.0 or newer
for best performance.
http://www.adobe.com.
8.1 Accessing the graphical user interface
The default IP address of the TNS544 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.
The TNS544 offers two options to alter the user interface IP address; through an Ethernet connection or using a USB terminal interface. If your management computer allows setting a fixed IP
address, change the IP address using the Ethernet option described in Section 8.3.1.
If a static address cannot be configured on your management computer, Section 8.3.2 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 9.
8.2 Password protection
Remote access to the device is controlled by password protection. If you access the TNS544 using

The passwords can later be changed, either from the Web GUI or via the terminal.
8.2.1 Resetting the password list
If a password is lost, the password list can be reset to factory defaults via the local USB terminal
interface. To reset the password list, type the following command in the terminal interface:
userdb factory_defaults
Note: The factory_defaults option on the userdb command is avail-
able without administrator previledges only when accessing the terminal
via the local USB interface. In remote terminal sessions with a Telnet
client, administrator privileges are required to run the same command.
8.3 Changing the IP address of the unit
The TNS544 is supplied with a dedicated management Ethernet port, labeled Control. The default
IP configuration (IP address and netmask) of the port is 10.0.0.10/255.255.255.0.
8.3.1 Changing IP address via the Web GUI
Changing the default IP address using the Web interface requires that your management computer
may be configured with a static IP address.
Note: Avoid connecting through a network at this stage, as this may give
unpredictable results due to possible IP address conflicts.
1. Connect an Ethernet cable directly between the PC and the Ethernet control port of the
TNS544. Configure the PC to be on the same sub net as the TNS544. See Figure 8.2.
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 correct IP address
settings. Click apply to activate the new parameters. Figure 8.1 shows this GUI screen.
Note: Contact with the unit’s GUI will be lost. Please type http://<your
new IP address> in your browser to reconnect to the unit.
Windows XP example
The screen-shot in Figure 8.2 shows how to configure the network interface in Windows XP to
communicate with the TNS544 with factory default settings. The IP address/netmask is set

to 10.0.0.11/255.255.255.0 which is on the same sub net as the TNS544, and does not conflict
with the IP address of the device.
Note: If several new devices are accessed, one after another, the ARP
cache of the computer from which the devices are being accessed may
have to be flushed between each device, since the same IP address will be
used for different MAC addresses. On Windows XP this is done on the command
line typing the command ’arp -d *’
8.3.2 Changing the management port IP address via 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 (setup_ftdi_usb_drivers.exe). (This step may be
omitted if the driver has already been installed.)
ID: um_tsoipswitch TNS544 TSoIP Switch User’s Manual Rev. 2.6.B (5219)
Page 42
42 Operating the Equipment
2. Connect your computer USB port to the TNS544 USB port using a suitable cable.
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. Test that the connection is successful by hitting the <Enter> key. If successfull an >app
prompt should be shown.
5. In the terminal, type the following command and press <Enter>:
net ipconfig --ip <ip address> --mask <subnet mask> --gw <default gateway>.
Example:
app>net ipconfig --ip 10.40.80.100 --mask 255.255.255.0 --gw 10.40.80.1
This will result in the IP address 10.40.80.100 being set. The subnet mask is set to 255.255.255.0
and the default gateway to 10.40.80.1.
Note: The product CD shipped with the TNS544 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. Drivers retrieved from http://www.ftdichip.com will also
work, but these may not have the same COM port number mapping.
8.3.3 Configuring automatic IP address assignment
The TNS544 can be configured to obtain an IP address automatically from a DHCP server on the
network. See section 8.3.1 for how to connect, and section 9.4.4.1.1.1 for how to configure this
from the GUI. Alternatively, configure it in the terminal by connecting as in 8.3.2 and issuing the
following command:
ipconfig --dhcp 1 --hostname <your_device_name>
Example:
ipconfig --dhcp 1 --hostname bonemachine-100
Replace <your_device_name> with the name to register in the DNS system for your device. After
this, it should be possible to contact the unit in a browser using the URL:
http://<your_device_name>
To disable automatic IP assignment, use the command
ipconfig --dhcp 0
TNS544 TSoIP Switch User’s Manual Rev. 2.6.B (5219) ID: um_tsoipswitch
Page 43
Operating the Equipment 43
Note: Hostname registration is only done via the DHCP server, so if
DHCP is not enabled the hostname is not registered. The default hostname
used is on the format TNS544-<serial-no>-<interface-no>
Note: If automatic IP address assignment is configured and the interface
is connected to a network that does not support DHCP, the interface will
not receive an address and will fall back to a link local address after about 1
minute, using the first available address in the range 169.254.1.0 - 169.254.254.255.
If you have a unit that has been configured with DHCP, but current network does
not support it, you should be able to connect to the device for reconfiguration on a
local network connection using the address 169.254.1.0. If more devices are using
link local addresses, try 169.254.1.1, 169.254.1.2, etc.
8.3.4 Detecting the management port IP address
If you have a unit and do not know the IP address of the Control Interface there are a few options
available. The simplest solution is connecting through the USB interface.
8.3.4.1 USB Interface
8.3.2 on how to connect to the unit using the USB Interface.
See
Type the following command to list the currently assigned IP addresses:
app>net ipconfig
8.3.4.2 Nevion Detect
If you are not able to connect through the USB Interface, you may use the Nevion Detect software.
This software may be found on the Nevion Product CD (version 2.20 and newer), or by contacting
Nevion Support (see Section 2.4). An User’s Manual is also included.
The Nevion Detect software detects devices by sending broadcast messages that the TNS544 and
other Nevion devices will recognize and reply to with some essential information. The PC running
Nevion Detect may be on a totally different subnet than the TNS544, such that the device will be
discovered regardless of IP addresses and IP submasks.
Warning: Some Ethernet equipment might block broadcast traffic. Con-
nect your PC directly to the TNS544 to avoid this.
Note: It is possible to avoid that the TNS544 is detected by the Nevion
Detect software. See Section 9.4.4.1.1 for details on how to do this.

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 E.
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.

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 9.4.1 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.

a comma separated value file (.CSV).
9.3.1 Current Status
This page displays the current status of the device. It consists of a block diagram illustrating the
device with its input and output ports, an overview of the currently active network interfaces and
a list of currently active alarms.
Block Diagram
The block diagram provides a compact view of the unit status. It shows:
• The name of the functional units of the device.
• The name and alarm status of each input/output port.
• The status of non-I/O port related alarms.
The alarm status is shown with colours indicating the severity of the alarm. The various
severities and colours used are described in

Access to additional information pertaining to the various ports of the block diagram is provided by hovering the mouse pointer over the port within the diagram. The port representations in the diagram also act as shortcuts to the corresponding configuration page for the
port. The shortcut is activated by clicking on the port in the diagram.
If an input switch is defined, it is shown in the status diagram as a box inside the device block
in front of a MUX block. The block shows the ports that are members of the switching group,
and the currently selected port. Clicking the switch block will take you to the configuration
page for the switch.
Right-clicking the status block diagram top bar offers a shortcut to clear device statistics parameters. Selecting Reset device statistics brings up a dialogue where you can select which
information to clear.
Current Alarms
The bottom part of the page shows the currently active alarms. Some alarms may contain
several sub-entries that are displayed by clicking on the arrow in front of the entry’s description. The severity of each alarm is represented by an error indicator (visually similar to a
LED). The colour of the indicator represents the severity level configured for the specified
alarm. The various severities and colours used are described in

The table consists of the same columns as the Current Alarms table, but does not show details by
default. You can change which columns to show, including the details column, in Section 9.4.2.4.
Additionally a column named Off Time shows the time the alarm condition was cleared. Rows
will not have the Off Time set if the alarm is still active.
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 TNS544.
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.
Details
An optional string providing more information about the alarm in human readable form.
The content and format of this string depends on the alarm type.
Beneath the alarm table is a caption showing the total count of alarms currently stored in the alarm
log.
To the right of the table are three buttons and a check box.
Clear Alarm Log
Clears all alarms from the alarm log.
Export to File
Saves the alarm log to a comma-separated value (.CSV) file. The button opens a file dialogue
where the user can choose the destination to save the file on the computer.
Export to Browser
Opens the complete log in a new browser window, showing the alarm log as a commaseparated value list. The format of this list is a text file (not HTML or XML).
Enable updates
This check box can be unchecked to stop the log from scrolling if new alarms are triggered
while watching the log.
The alarm log is stored in non-volatile memory, so the content is kept even if the unit is rebooted.

This page provides an interface to configure globally the behaviour of all alarms. By default ports
use the global configuration settings but each port alarm can be configured individually to override these settings.
For each alarm a custom severity level can be configured. In addition the alarms can be omitted
from the alarm log and trap transmission.
Edited rows are highlighted until changes have been applied.
Tip: For the Log and Send Trap columns, you can quickly select/deselect
all items by right-clicking on the header fields in the columns.
9.4.2.3 Relays and LED
This page lets the user configure the alarm severity level that shall turn the relays and alarm LED
on. The behaviour of Alarm relay 1 and Alarm relay 2, and the Alarm LED may be configured
individually for each alarm severity level. Note that the Alarm relay 1 and the Alarm LED will
always be enabled for alarm severity level Critical, as indicated by the disabled check boxes in the
Relay and LED level triggers field. The current state of the relays and LED is indicated inside the
associated brackets.
The General purpose input field allows the user to enable pin 9 of the alarm D-SUB connector as
a remote reset input. See Section 7.6.1. GPI status indicates if the input signal is active.
For further details on the physical relays refer to Section B.5.1.
The Virtual Relays field shown in Figure 9.12 also includes settings for the so-called virtual relays.
These are programmable status indicators that can be set to react to any specific alarm condition.
In the simplest case you may want to enable a relay in case a specific alarm ID turns up. In another
case you may want to enable a relay if a specific alarm turns up on a given port.

Figure 9.12 Relays and LED configuration
Each relay status are exported on SNMP. Activation of a virtual relay also generates a specific
alarm, named "Virtual alarm relay activated" (ID=169).
The key element in the settings of the virtual relays is the Expression value. The expression is
very close to SQL in syntax and specifies when the relay should be activated. The behaviour is as
follows for each virtual relay:
1. Each active alarm event is evaluated against the Expression for the virtual relay (if en-
abled).
2. If the expression evaluates to true, the Count value is increased by 1. You can at any time
see the current count value. The Count value simply tells you how many of the current
(active) alarm events in the unit that matches the expression.
3. If the count value is larger than or equal (>=) to the Count Thresh. value the relay is
activated.
The expressions are validated before they are accepted by the unit. Table 9.1 shows the field
values you may enter in an expression.

In the expressions you may enter parentheses to group sub-expressions together. Together with
the supported list of operators this gives great flexibility in constructing advanced “match” patterns.
Table 9.2 summarises the operator types you are allowed to use. Please note that the examples
below are used for illustration purposes only. For example, the plus and minus operators may not
be very useful in practise, but they are included in this table for completeness.

!= Not equal id != 169
AND Logical AND id = 169 AND port = 2
OR Logical OR id = 169 OR id = 200
IN Set operator. Returns true if left-hand part is included in set to the right. id IN (169,200,201)
+ Addition id + 9 = 169
- Subtraction id - 8 = 160

<= Less than or equal id <= 100
Some examples are given in Table 9.3.
Note the last example in the table: Here the count threshold value must be set to 2 to get the
expected behaviour. This is because the expression entered matches two different alarm events
(port=1 or port=2), and in order to match them both two matches are required in the global alarm
list.

Status
The status of the time synchroniser.
Active
The time source currently in use by the time synchroniser.
The Manual Adjust Time field allows the operator to set the time. The manually configured time
will only be used when no other time sources are configured in the Prioritised time sources list.
The Timesource prioritisation field contains two lists showing configured time sources. Disabled
time sources are greyed out. Enabled time sources are shown with an indication of the time source
status. The list to the right shows time sources that are defined but not used by the time synchroniser. Enabled time sources may be moved to the leftmost list by using the arrow-left button, and
back again by using the arrow-right button. Time sources in the left hand list are used by the time
synchroniser to set the time. They are listed in prioritised order; the source with the highest priority at the top. The order of priority can be altered by clicking an item in the list and using the up or
down arrows to the left of the list to increase or decrease, respectively, the item priority. The time
synchroniser will use the time source with the highest priority whose status is “OK” (represented
by a green indicator).
To add a time source to the system, click the “Add Timesource” button, which brings up the dialog
shown in
Figure 9.15 with the following fields:

Lists ports that can be used as time sources with the selected time source type
(Figure 9.15. Multiple entries can be selected to add more than one time source.
For switched inputs, you may select the time source to get time from the input
switch group, which will make the time source retrieve the time from the currently
active input in the switch.
To remove time sources, Select them in the list and click the “Remove Timesource” button. Time
sources for dynamic ports such as IP inputs and Switch inputs, are automatically removed if the
dynamic port is removed.
Located belowthe lists is also a field to define the maximum allowed time interval between updates
from the currently used time source. Exeeding this interval the source is considered “Not OK” and
the synchroniser selects the next source in the prioritised list.
Upon selecting a time source, the Timesource Details box at the bottom right of the page provides additional details relating to the selected time source. Depending on the type of time source
selected the box may contain some or all of the following parameters:
Active
A checkbox to enable or disable the time source. Disabled time sources are never updated.
Time sources configured and present in the prioritised list must be removed before they can
be disabled.

9.4.3.1 Daylight saving time
Daylightsaving time (DST) can be set in the field below the Manual Adjust Time field. The effect of
having it enabled is that the local time on the unit is adjusted for daylight saving time. The current
time will show the daylight saving adjusted time, with correct UTC offset. This will mainly have
an effect on alarm log entries and reading the time from the GUI. When enabled, there are four
DST modes to choose from:
Europe
Standard European settings. Daylight saving time starts on the last Sunday in March at 1AM
UTC, and ends on the last Sunday in October at 1AM UTC.
USA
Standard USA settings. Daylight saving time starts at 2AM local time on the second Sunday
in March, and ends at 2AM local time on the first Sunday of November. This setting does not
take into account the exceptions where daylight saving time is not observed, such as Arizona,
Hawaii, Puerto Rico, American Samoa, Guam, Northern Mariana Islands and the United
States Virgin Islands. These locations should simply have daylight savings time disabled.
Manual dates
Manual dates which can be inputted in the autumn and spring fields that appear when this
option is chosen. Will only occur on these times, and need to manually be updated in order
to change the following years. If both the manual dates has passed, the time is set to not be
in daylight saving, even if the last date was a spring date. The number of minutes to adjust
the time for daylight savings can be set in the Offset in minutes field.
Manual recurring
Gives drop-down lists to input a rule, such as “First Sunday in February 02:00”. This will

set dates based on the selected input, and happens each year on that day. The number of
minutes to adjust the time for daylight savings can be set in the Offset in minutes field.
If daylight saving is enabled, a status field showing the current time status with daylight savings
appears. If daylight saving is disabled, this field is not visible. The status field shows the following
information:
Current time
The current time as reported by the device.
Currently in summer time
Whether or not the current time is in daylight saving time.
Setting clock in
Countdown to the next time time will be adjusted to or from summer time. If it displays “No

server is used to map names to IP addresses.
9.4.4.3 IP Routing
Figure 9.27 IP Routing
The IP Routing table lets the user configure IP routing rules for the unit. These rules tell the unit
which interface to send IP traffic to, based on the destination IP address of the traffic.
Destination
The destination IP address to use for matching against this routing rule.
TNS544 TSoIP Switch User’s Manual Rev. 2.6.B (5219) ID: um_tsoipswitch
Page 81
WEB Interface 81
Netmask
The subnet mask to use for matching against this routing rule.
Gateway
The IP destination to send a packet to if the destination address of the packet is on a different
subnet than the destination interface.
Interface
IP packets matching this rule will be sent through this interface.
Metric
The metric of the routing rule. If more than one rule matches a destination address the rule
with the lowest metric will be used.
When an IP packet is sent from the unit the destination address of the packet is matched against
the configured routing rules. If the destination address matches one or more rules the rule with
the lowest metric will be used. The packet will then be forwarded to the interface determined
by this rule. If the destination address is on a different subnet than the configured interface the
packet will be sent to the gateway determined by the rule.
Below the table is a checkbox where the user can Allow IP forwarding. If enabled incoming TCP
packets that are not addressed to the unit will be forwarded to an interface according to the routing
rules. The receiving interface must have management traffic enabled to forward TCP traffic to a
different interface.
Note: Modifying the IP routing rules may cause loss of contact with the
unit. Make sure you will still be able to contact the unit with the new
settings before applying the changes.
9.4.4.4 TXP Settings
Figure 9.28 TXP Settings
TXP is a Nevion proprietary HTTP/XML based protocol designed to retrieve configuration and
status information using WEB/HTTP requests. TXP exists side by side with an SNMP agent and
provides an alternative way to access data in a product. TXP and SNMP therefore complement
each other.
This page contains settings to determine how the unit should respond to TXP queries.

9.4.4.5 SNMP Settings
The Simple Network Management Protocol (SNMP) is used to monitor network-attached devices
for conditions that warrant administrative attention. This page gives access to SNMP settings such
as destination IP addresses of trap receivers and community string. It Also displays a log of the
latest traps sent by the unit.
The Trap Destination table lets the user configure the trap servers that should receive SNMP traps
from the unit. To add a server click the Add new button, enter an IP address, then click the Apply
button. To delete an entry select a server entry from the list and click the Delete button.
The Settings group of parameters configures MIB-2 parameters and SNMP password protection.
The SNMP version to use for traps, version 1 or version 2, may be selected. When selecting to
transmit SNMPv2 traps, two additional options are applicable.
Status change traps
Selecting this causes a trap to be transmitted each time the overall device status changes.
Alarm event forwarding

The tools menu contains helpfull tools for network debugging.
9.4.4.6.1 Ping
The ping tool can be used to check for connectivity between devices. It is especially useful to ping
the receiving data port from the IP transmitter to see if the receiver can be reached.
IP destination
The IP address of the receiving data port. The ping messages will be routed to the matching
Ethernet port, either data or management, or to the port configured as default management
interface if the specified IP address does not match either of the two sub-nets. Note that if

you are pinging between data interfaces, the Allow ping response option on the network page
Advanced tab (see Section 9.4.4.1.3) must be enabled both in the transmitter and the receiver.
Note: When the IP destination is a multicast address one cannot expect to
receive a response to a ping request. It is recommended to test connectivity
using the device’s actual IP address.
TTL (Time To Live)
Enter the time to live value for the ping messages here. The time to live value is a field in the
IP protocol header that is decremented once for each router that the datagram passes. When
the count reaches 0, the datagram is discarded. You can use this to check the number of
routers between the transmitter and the receiver by starting with a low value and increment
it until ping responses are received. TTL is also specified for each data channel on the IP
transmitter, and must be high enough to reach the receiver. Values range from 1 to 255.
Ping count
The number of ping messages to send. The messages are transmitted with an interval of
about 1 second.
MTU
Maximum Transfer Unit. Specify a length for the ICMP frames to check that frames with
given length pass through the network. The ICMP data payload size is adjusted to yield
Ethernet frames with the specified length. The ping messages are transmitted with the “don’t
fragment” bit set.
Start
Press this button to start the pinging sequence configured above. The status of the ping
sequence is displayed in the status frame. Status values are reset on pressing the start button.
After pressing the start button the label switches to Stop, and the button can be pressed again
to cancel the pinging sequence.
OK responses
The number of ping responses received.
Timeouts
The number of ping requests that were not answered. If the timeout counter is incrementing
while the OK responses counter is zero, there is no contact with the specified IP address.
TNS544 TSoIP Switch User’s Manual Rev. 2.6.B (5219) ID: um_tsoipswitch

9.4.6 Configuration Manager
The Configuration Manager, shown Figure 9.34 provides an interface for managing the device
configuration as “snapshots”. From here, snapshots of the device configuration settings can be
taken and stored locally, or exported from the device as XML files. Also, configuration files may
be imported and applied.
The device allows for up to 8 configuration snapshots to be stored and managed locally, not including the current running configuration.
9.4.6.1 Save/Load Configs
Figure 9.34 Configuration manager
9.4.6.1.1 Save Configuration To File
This is the interface for exporting the current running configuration as an XML file. Clicking the
Save Config button prompts the user with a standard Save as dialogue requesting a location to
store the configuration file. This location can be any place the user has access permissions to write
files.
TNS544 TSoIP Switch User’s Manual Rev. 2.6.B (5219) ID: um_tsoipswitch
Page 89
WEB Interface 89
During the transferof the file from the device to the user’s system the user has the ability to click the
Cancel button to cancel the transfer. Note that, depending on the web browser used, an incomplete
file may be left on the user’s system after canceling.
Upon completion of the transfer the transfer progress bar will turn green. If an error occurs during
the transfer the progress bar will turn red and display an error message.
Files exported from the device using this option contain a complete device configuration and can
be restored to the device at a later time. Or it may be installed on another device using the Load
Configuration option.
9.4.6.1.2 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 administratorto 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 9.4.6.1.4
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.
9.4.6.1.3 Load Configuration from Remote Device
The Load Configuration from Remote Device makes it easy to copy the configuration of another
device to this device. This device will therefore be a clone of the remote device, except for device
specific parameters such as IP addresses and product name. Loading a configuration from Remote

Device is essentially equal to saving the configuration file of another device, and uploading it to
this device.
The configuration field includes the IP address of the remote device. Entering an IP address and
pressing the Contact Device button will check if the connection is valid and display some information about the device if successful. If the connection is valid, the Load Config button will become
clickable.
Note: It is possible, but not advisable, to load configuration from other
model types. Even if loading from the same model type, loading a configuration might also fail, especially if the two devices have different feature
sets. See Section 9.4.7.1 for a list of features.
Please see next chapter (Section 9.4.6.1.4) for a description of the load options.
9.4.6.1.4 Load options
These options are used to modify the behavior on configuration loading. The options are available
when loading from a file (Section 9.4.6.1.2) and when loading from a remove device (Section
9.4.6.1.3) .
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.
Update
Only update nodes that are present in running configuration and in file loaded, i.e no
list entries are added or removed.
Overwrite
This parameter is used to modify how specially tagged parameters are handled during file
loading.
Access control parameters
Tick to overwrite SNMP community strings and TXP access parameters.
Device identifier parameters
Tick off his check box to overwrite the device identifiers device name and inventory ID.
