4.5.1.2 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.
4.5.1.3 Connecting to the AC power supply

5.1 Introduction
The CP560 is a DVB-T2 gateway designed for the encapsulation of Transport Streams (TS) in T2MI frames. The product offers an easy-to use WEB based user interface, a flexible and powerful
T2-MI encapsulation module and integration with network management systems via the SNMP
interface.
This chapter gives a brief description of the CP560 inner structure, allowing a better understanding
of the device’s functionality, its operation mode and its applications.
Figure
description of the different blocks is provided in following sections.
5.1 shows a functional block diagram of the main components inside the CP560. A detailed
5.2 TS inputs
The CP560 can include up to 10 ASI ports, 8 of them can be used as input ports and 2 as output
ports.
The number of simultaneous TS inputs that can be enabled is limited by a software licence key.
The default configuration includes only one input port and two output ports. If needed, further
inputs can be enabled with the software licence key.
5.3 TS output
The CP560 generates a T2-MI output. When using ASI output,the transport stream is presented
on at least one ASI output port. In addition one port is programmed to carry the same signal, as
described in Section 6.1.2.
The output is always re-clocked, configuring a wanted bitrate for the output stream.
The CP560 can transmit the same transport stream over IP via the extra physical Ethernet data
connector(s) or via an SFP module inserted in the SFP slot.
5.4 SFN adapter
The product is fitted with an SFN adapter that generates an accurate DVB-T2 timestamp. This
enables synchronisation of the output clock to the Network Time Protocol (NTP) or a 1PPS signal
for operation in SFN networks. The 1 PPS signal can be taken from an external source.

5.5.1 Input and output
The CP560 supports MPEG transport streams over IP, the functionality is protected with a separate
SW licence.
The CP560 has 8 IP inputs, these are modelled to have the same functionality as the ASI input
ports, and content received will be available to the DVB-T2 Gateway generating the output. The
input streams can be either SPTS or MPTS and streams with or without RTP layer are accepted.
The DVB-T2 Gateway can generate one output and the operator chooses whether to transmit this
stream over IP or not.

5.5.2 Protocol mapping
Figure 5.2 Protocol mapping
When transmitting T2-MI streams over IP, the protocol mapping is according to figure 5.2. 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.
5.6 T2-gateway module
Figure 5.3 DVB-T2 Gateway module
The DVB-T2 Gateway module illustrated in figure 5.3 is the main module of the CP560, it encapsulates TS-input packets in Baseband frames, generates an accurate timestamp and generates
L1-signalling frames. The resulting T2-MI frames are packetized and encapsulated again in TS
packets to be transported over a network.
According to the DVB-T2 frame structure, T2-MI frames carrying user data are sent first followed
by a timestamp frame and a L1-frame. The time stamp frames and L1-frames are generated accordingly to the settings defined in the user interface.
The DVB-T2 packet bitrate is kept constant by the time source or the 1PPS signal, this prevent the
overflowing of the buffer on the modulator side when the unit and the modulator uses the same
time source.

26 Functional Description
5.7 Management sub-system
The management subsystem is a set of modules that handles all the interfaces to monitor and
control the operation of the CP560.
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
• 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.
5.7.1 Graphical user interface
Operators monitor and control the CP560 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 CP560 can be controlled from the web
GUI.
5.7.2 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.
CP560 DVB-T2 Gateway User’s Manual Rev. 2.2.B (5008) ID: um_t2gateway
Page 27
Functional Description 27
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
• IP network parameters
• ASI Port mappings
• On-device stored configurations
5.7.3 Alarm manager
The CP560 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 CP560 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.

28 Functional Description
5.8 Time synchronisation
The CP560 contains an internal real-time clock that is used for internal timestamps and the generation of DVB-T2 timestamps for SFN operation.
In order to generate precises SFN timestamps, the CP560 needs to be connected to both a NTP
timesource (for absolute time in seconds) and 1PPS (for subsecond time).
The internal time can be synchronised as follows:
• From NTP servers using SNTP protocol. Up to four NTP servers can be configured for
NTP server redundancy (see section
• Connect 1 PPS signal to the CP560 (see section 6.1.1) and enable 1 PPS synchronisation
(see section 8.4.6).
• Then Resync the internal time of the CP560 (see section 8.6.4.1).
8.4.4).

instructions, prior to connecting the units power cable.
6.1.9 Ethernet Management Port
The CP560 provides one Ethernet port for control and management. Connect the management
port to the management network. The LEDs for the management port are used as follows:
6.1.10 Technical Earth
Connect the Technical earth to a suitable earth point.
6.1.11 Alarm/Reset
The unit is equipped with a 9-pin male DSub 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. Please refer to section
the relays.
The pin out of the connector is shown in table 6.7.
When there is a critical (level 6) alarm in the unit, 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. When the
above conditions are not present, 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 not to be 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 active 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).

Operating the Equipment 35
7 Operating the Equipment
The CP560 is configured and controlled locally and remotely through a Flash-based Web interface.
The onlyapplication 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 CP560. 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
http://www.adobe.com.
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.
7.1 Accessing the graphical user interface
The default IP address of the CP560 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 CP560 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 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.
7.2 Password protection
Remote access to the device is controlled by password protection. If you access the CP560 using
the USB terminal interface a password is not required.
There are 3 user levels providing different user privileges, each with a separate default password:
Username Default password Privileges
admin salvador Full access to device
operator natal Configure setting, cannot alter passwords
guest guest View configuration and alarm logs
ID: um_t2gateway CP560 DVB-T2 Gateway User’s Manual Rev. 2.2.B (5008)
Page 36
36 Operating the Equipment
The passwords can later be changed, either from the Web GUI or via the terminal.
7.2.1 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.
7.3 Changing the IP address of the unit
The CP560 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.
7.3.1 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
CP560. Configure the PC to be on the same sub net as the CP560. See Figure 7.2.
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 7.1 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 7.2 shows how to configure the network interface in Windows XP
to communicate with the CP560 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 CP560, 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 *’
7.3.2 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_t2gateway CP560 DVB-T2 Gateway User’s Manual Rev. 2.2.B (5008)
Page 38
38 Operating the Equipment
2. Connect your computer USB port to the CP560 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 CP560 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.
7.3.3 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.
7.3.3.1 USB Interface
See 7.3.2 on how to connect to the unit using the USB Interface.
Type the following command to list the currently assigned IP addresses:
app>net ipconfig
7.3.3.2 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 CP560 and
other Nevion devices will recognize and reply to with some essential information. The PC running
CP560 DVB-T2 Gateway User’s Manual Rev. 2.2.B (5008) ID: um_t2gateway
Page 39
Operating the Equipment 39
Nevion Detect may be on a totally different subnet than the CP560, such that the device will be
discovered regardless of IP addresses and IP submasks.
Warning: Some Ethernet equipment might block broadcast traffic. Connect your PC directly to the CP560 to avoid this.
Note: It is possible to avoid that the CP560 is detected by the Nevion
Detect software. See Section 8.4.5.1.1 for details on how to do this.

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.
Figure 8.3 The status header
In the status header the product name is shown on the left hand side, along with the Nevion logo.
The status bar displays an 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 G.
Several items are presented in the right corner/section of the header. Starting from the left:
• The user defined device name, if entered.
• A button to log out from the GUI.
• A button to switch current user level.
• A text showing the current user name.
• The local device time.
• 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.
• 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

a comma separated value file (.CSV).
8.3.1 Current Status
Figure 8.5 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 Appendix G.

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 Appendix G.
The Current Alarms table contains six columns:
Description
Description of the alarm condition.
For sub-entries, the extended index is shown in brackets. To the left is an indicator visualising
the severity of the alarm. The indicator has a tool-tip providing a textual description of the
alarm severity.
On Time
The time when the alarm was raised.
Alarm type
Category of the alarm, i.e. Port, System, Switch etc.
Source
This identifies the source of the alarm. For port alarms, this is a reference to the specific
port raising the alarm. This field has a tool-tip showing the subid1 and subid2 values for the
alarm.
Subid1
Reserved for future use in multi-slot chassis and is always set to 1 in the CP560.
Subid2
The device or port to which the alarm relates. The value is zero for alarms that are
related to the device rather than to a specific port. Values of 1 and up reference specific
ports.
Alarm ID
Each alarm condition has an associated numerical alarm ID.

Details
An optional string to provide more alarm information in human readable form. The format
of this string depends on the alarm type. Hovering the mouse over this field produces a
tool-tip displaying the full text.
A detailed overview of alarm conditions is given in Appendix G.
8.3.2 Alarm log
Figure 8.6 Alarm log
The alarm log shows every alarm that has been triggered since the last time the alarm log was
cleared.
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 8.4.2.4.
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 CP560.
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.
ID: um_t2gateway CP560 DVB-T2 Gateway User’s Manual Rev. 2.2.B (5008)
Page 46
46 WEB Interface
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.
The log is circular. Events occurring after the maximum number of entries has been reached overwrite the oldest entries in the log. The maximum number of stored entries is 10000.
8.4 Device Info
The device info page contains all the information and settings that are not related to a single input
or output port. It is divided into multiple sub pages accessed via the navigation list to the left. In
the list of physical interfaces in the navigation list, the currently active interface is shown in bold.
See Figure 8.7.
The exact layout of the navigator depends on the resources and features currently available in the

Product name
Displays the name of the product as designated by Nevion.
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.
Device up time
The amount of time that has passed since the device was last reset.
Internal temperature
This shows the current internal temperature of the unit in degrees Celsius and Fahrenheit.
Fan speed
This bar chart shows the current speed of the device fans relative to full speed.
Flash Power LED button
The Flash Power LED button activates flashing the green power LED on the device in question. This is useful for identifying which device is currently being configured. Each click of
the button extends the blinking period by five seconds up to a maximum of about 30 seconds
of blinking.

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.
Figure 8.11 Relays and LED configuration
For further details on the physical relays refer to Section B.5.1.
The Virtual Relays field shown in Figure 8.11 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.
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:
ID: um_t2gateway CP560 DVB-T2 Gateway User’s Manual Rev. 2.2.B (5008)
Page 52
52 WEB Interface
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 8.1 shows the field
values you may enter in an expression.
Table 8.1 Legal field values to use in expressions
Field name Extracts from event: Type Sample expression
id Alarm ID Number id = 169
text Alarm text Text text = ’Defective fan’
type_num Type number Number type_num = 13
type_text Type text Text type_text = ’port’
sev Severity (number 2-6) Number sev = 6
details Alarm details (text) Text details = ’PID 113’
subid1 Alarm subid1 value Number subid1 = 1
subid2 Alarm subid2 value Number subid2 = 2
subid3 Alarm subid3 value Number subid3 = 1190
port Synonym for subid2 Number port = 2
service Synonym for subid3 Number service = 102
pid Synonym for subid3 Number pid = 2000
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 8.2 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.
Table 8.2.a Legal operators to use in expressions

= Equal id = 169
!= Not equal id != 169
AND Logical AND id = 169 AND port = 2
OR Logical OR id = 169 OR id = 200

Table 8.2.b Legal operators to use in expressions
Operator Description Sample
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
* Multiply id * 10 = 100
/ Divide id / 20 = 8
> Greater than id > 100
< Less than id < 90
>= Greater than or equal id >= 100
<= Less than or equal id <= 100
Some examples are given in Table 8.3.
Table 8.3 Expression examples
Task Expression Count threshold value
To generate an alarm when any alarm with
ID = 200 turns up (independent on source)
To generate an alarm when alarm with ID =
200 turns up on port with ID = 1 (subid2 =
1)
To generate an alarm when alarm with ID =
200 turns up on both port 1 AND port 2
id = 200 1
(id = 200) AND (port = 1) 1
(id = 200) AND ((port = 1) OR (port
= 2))
2
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.

installed in the chassis and the meaning of the different choices are:
Mode
Direction of the port, with two choices:
Input
Use the port as an ASI input to the multiplexer. All input ports can be used, but the number of inputs that can be enabled simultaneously is limited by the licence key Number
of input ports activated.
Output-Copy
Use the port as an ASI output, transmitting the multiplex generated by the unit.
The valid selections are also documented in

PLP
If an ASI port is currently being used as input source for a PLP, the PLP id will be listed in the
PLP column. ASI inputs used as source for a PLP may not be port mapped to ASI outputs
until it has been removed as source for the specified PLP. This must be done as shown in
Section 8.6.4.3.
Configure the mapping that best matches your needs and press apply to activate the new matrix.
Re-configuration does not require re-booting. The choices made will be reflected in the logical
block diagram of the device on the status screen (see also Section 8.3.1)
Note: The port map settings are tagged to follow the device (see Section
5.7.2, and even though the parameters are exported in the configuration
file format, they are not overwritten when loading a configuration file via

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).

8.4.5.2 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.

Figure 8.26 IP Routing
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.
8.4.5.3 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.

options:
Disabled
No traps are transmitted when alarms appear or disappear. If the Status change traps
check box is checked, device status traps are still transmitted.
Basic
The device forwards alarm events as SNMP traps. If there are several sub-entries only
a single trap is transmitted.
Detailed
The device forwards alarm events as SNMP traps. If there are several sub-entries, an
SNMP trap is transmitted for each sub-entry.

8.4.5.5 Tools
The tools menu contains helpfull tools for network debugging.
8.4.5.5.1 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.
Figure 8.29 The Ping tool
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 8.4.5.1.3) 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.

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.
Last roundtrip
The round trip time measured for the last ping request in units of milliseconds.
Average roundtrip
The average round trip time measured for the ping requests in this session. The value is reset
every time the start button is pressed.
Min roundtrip
The shortest round trip time registered for the ping requests in this session.
Max roundtrip
The longest round trip time measured for the ping requests in this session.
Remaining
The number of remaining ping requests in this session.
8.4.5.5.2 Traceroute
The traceroute tool can be used to debug the network connectivity with a given host bytracking the
router hops between the CP560 and the host. Traceroute uses ICMP ping messages with increasing
TTL to track the router hops.
Settings
IP Destination
The IP address of the host to check. IP routing decides which interface the ICMP messages are sent on.
Number of hops
This parameter sets a roof to the number of hops that are tracked. Normally this parameter can be set fairly low.
MTU
Maximum Transfer Unit. This parameter can be used to transmit messages with a given
length. ICMP messages are transmitted with the don’t fragment bit set to yield errors
when MTU of a link is too small for the frame.

8.4.7 Configuration Manager
The Configuration Manager, shown Figure 8.33 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.
8.4.7.1 Save/Load Configs
8.4.7.1.1 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.
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.

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 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
CP560 DVB-T2 Gateway User’s Manual Rev. 2.2.B (5008) ID: um_t2gateway

WEB Interface 83
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 8.4.7.1.4
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.
8.4.7.1.3 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 8.4.8.1 for a list of features.
Please see next chapter (Section 8.4.7.1.4) for a description of the load options.
8.4.7.1.4 Load options

transmit the file from the administrator PC to the device. Once the file has been transferred,
it is verified using and internal checksum value and set as the new active firmware image.
If the upload is successful the progress bar turns green and the unit reboots itself loading the
new image, unless the Reboot on success option has been unchecked.
If the upload is unsuccessful the progress bar turns red and an error message is displayed in
the Status field.
Cancel
The Cancel button is enabled during the upload process and can be clicked to cancel the
operation. It is not possible to continue a cancelled upload.
Reboot on success
This checkbox is checked by default but can be unchecked to disable automatic reboot upon
SW loading completion. If this option is not checked the SW will load but will not be activated
before the user performs a manual reboot. Note that this option is not stored on the device,
and Reboot on success will be enabled next time you enter the SW upgrade page.
During SW loading, an alarm SW loading in progress is set with the Details field displaying the
IP address of the machine from which the loading was initiated. The alarm is turned off when the
loading is completed or terminated.
If the Reboot on success option is active the unit will automatically reboot when loading is complete, otherwise an alarm New SW pending is set to indicate that a new SW will be used on next
manual reboot.
After uploading, if the Progress bar shows OK but the web interface does not change to the Waiting
for reset state, allow some time for the device to reset itself and then reload the web UI via the
web browser reload button.
Note: It is recommended to verify the new software version via the “Product Info” page (Section 8.4.1) to verify that the update was successful
and the latest software revision is active.
8.4.8.3 Feature Upgrade
The Feature Upgrade sub-page provides an interface to upload new software licences to upgrade
the feature set of the device. The licence key is provided as a text file. Paste the content of file into
the text area and click the Load Key button.
Some features do not require a restart of the device when upgraded, they are marked as “hot” in
the feature list. If you load a licence changing only hot-upgradable keys, you will get a message
back in the load text box telling you that no reboot is required. If any non-hot licence has changed,
the device needs to be restarted to activate the new feature(s).
Reset can be performed from the GUI as explained on the Maintenance > General tab in Section
8.4.8.1.
