HYBRID SWITCHING SOLUTION

For Uncompressed, High Resolution Video & KVM Systems

Thinklogical’s TLX Matrix Switches are high performance, non-blocking switches for complete end-to-
end switching of video, audio and peripheral signals over multi-mode or single mode fiber optic cable
or CATx cable.

TLX switches are protocol agnostic, supporting most video, audio and peripheral signals and allow users
to consolidate all of their system switching requirements in a single chassis. TLX Matrix Switches are
ideal for small or large system applications, with switch sizes ranging from 12 ports to 640 ports. Each

port supports 10Gbps bandwidth, preserving signal integrity to provide uncompressed, high resolution
video with no artifacts, latency or lost frames. Thinklogical’s re-clocking technology ensures that every

video and data stream is delivered in perfect synchronization.

SECURITY

Creating physical separation between potential threats (users) and the target (secure data) is essential

to a secure system design. Thinklogical’s system permits users to access sources up to 80 kilometers
away, with no performance degradation. System administrators can safeguard sources in a

centralized location, allowing users to maintain remote access to the sources, but with no means to
breach the system, either accidentally or intentionally (such as downloading sensitive information onto a
USB drive).

PARTITIONED AND RESTRICTED SWITCHING

To protect data between multiple networks, partitioning allows the switch resources to be divided to

support more than one network without allowing switching between networks. Restricted switching
allows the administrator to manage access on a port-by-port basis. Partitioned and restricted switching is
enabled through the switch’s firmware, which means a threat would have to physically access the switch
to tamper with the settings.

Note: Partitioning and Restricted Switching security features are only available with

fiber-optic Matrix Switch applications. CATx Matrix Switching applications do not offer

the same level of security.

SYSTEM FUNCTIONALITY

TLX Extension Systems have a simple transmit and receive design. The TLX Transmitter connects to the
source to receive video, audio and peripheral data. Utilizing Thinklogical’s proprietary multiplexing

technology, the data is transmitted over fiber through 10Gbps SFP+ technology for up to 80
kilometers, or over CATx cable for up to 100m. At the TLX Receiver, Thinklogical de-multiplexes the

data stream to deliver uncompressed, high resolution video, audio and peripheral data at the end-user’s
workstation.

TLX extension systems are highly configurable to suit the requirements of any application. Extenders are
configurable to support up to 4K video (4096x2160) @ 60Hz, full duplex stereo audio, serial (RS-

232), USB HID, USB 2.0 (480Mbps) and 10/100/1000 Network. The TLX design offers support for both
HDMI 1.4 and DisplayPort 1.2 connector types in a single extender, with full support for HDCP

content.
Additionally, TLX extension systems support embedded audio, with the ability to de-embed audio at the

receiver. All extenders are equipped with an additional output for a local display, as well as an Ethernet
port for configuration management and updates.

For high-availability applications, redundant fiber path configurations are also available.

The TLX extension systems are compatible with a full line of scalable, non-blocking TLX
matrix switches, ranging from 12 to 640 ports.

FORM FACTOR

TLX extension systems are available in a modular form factor. The modular extenders are compact and
hot-swappable, so users can field-configure any modular chassis. For fiber extenders, the optical
modules, or SFPs, are also hot-swappable. The modular system promotes system flexibility,

scalability and reduced maintenance.

The TLX Modular Extender Chassis Line

Several chassis types are compatible with all TLX modular extenders, allowing users to mix-and-match
chassis types to reduce the overall footprint of the design. Users can choose from the resilient, rack
mount chassis (housing up to four video extenders or up to two KVM extenders in a single rack unit) with
redundant and hot-swappable power supplies, or from our more compact, space-saving designs for
desktop applications.

Each TLX Chassis accommodates the full line of TLX Extender Products.
 The CHS-000004 is a rack-space-saving, high-reliability rack mount unit for up to 4 modules of

HDMI, DVI, RGB or SDI in a compact 1U chassis.

 The CHS-000002 is a desktop solution that accommodates one 7.4” or two 3.7” modules of HDMI,

Source 1 is connected to

Destinations 13, 14 & 15.

Pressing Destination 16 when

the LEDs are lit adds it to Source

1’s outputs.

SOURCES 1-24 Used to select any one of the 24 Matrix Switch

inputs. Only one input can be selected per action. (Pressing a

button illuminates it to confirm the selection.) A previously selected
input will be deselected upon selecting a new input. To deselect,
simply press the illuminated button and the button shall no longer
be illuminated/selected. When an input is selected, all the

corresponding connected DESTINATION ports shall illuminate,
reporting the full connection map of the selected input. If no

DESTINATION ports illuminate, then the input is not connected.

DESTINATIONS 1-24 Used to select Matrix Switch outputs. If an

input and output(s) are illuminated, then selecting another
output will enable an additional output to the connection map. If

no prior input or output(s) are illuminated, then selecting an output
will illuminate the corresponding connected input and output(s). To
deselect, simply press the illuminated button and the button shall no
longer be illuminated/selected.

TAKE In MANUAL mode (as opposed to AUTO mode),

connections/disconnections require pressing the
TAKE button. After the connection/disconnection is

performed, the selected SOURCE and

AUTO In AUTO mode, connections are made or broken immediately after a DESTINATION button

is selected (so the TAKE button will not be required) or deselected (so the DISCONNECT button will

not be required).

 Any selection of an unilluminated DESTINATION while a SOURCE is selected (illuminated) will

cause that SOURCE to be connected to the DESTINATION.

 Pressing a DESTINATION while illuminated (which means it is connected to the currently

illuminated SOURCE) will cause that DESTINATION to be disconnected and no longer illuminated.

DESTINATION(S) will no longer remain illuminated.

LOCK OUT Press the LOCK OUT button to disable the following action buttons: MACRO,

SNAPSHOT, AUTO, TAKE, DISCONNECT and DESELECT. Selecting the SOURCE or DESTINATION

will continue to provide connection status information only. Creating MACRO(S) and SNAPSHOT(S) will
be performed in the LOCK OUT mode.

DISCONNECT In MANUAL mode, after illuminating a SOURCE and one or more DESTINATION (S),

press the DISCONNECT button to disconnect all illuminated DESTINATION (S) from the illuminated
SOURCE. After the disconnect is performed, the selected SOURCE and DESTINATION (S) will no
longer remain illuminated.

BIDIRECTIONAL This is a special TAKE button which supports full duplex connectivity. For

example, in MANUAL mode when SOURCE 1 and DESTINATION 2 are illuminated, pressing the
BIDIRECTIONAL button connects both the selected SOURCE 1 to DESTINATION 2 as well as
SOURCE 2 to DESTINATION 1.

LED TEST Runs an automatic test of all LEDs collectively and individually for color and functionality.
MACRO n When in LOCK OUT mode, holding one of the MACRO buttons for >5 seconds will capture

currently connected DESTINATION (s) (but not those that are disconnected). When in NORMAL mode,

selecting that MACRO button will ‘add’ the MACRO connections to the existing connection map.

TLX24 Matrix Switch Product Manual thinklogical Rev. C, August, 2016

THE NETWORK INTERFACES

The default subnet used by the TLX24 is 192.168.13.xxx. Users may change to their own subnet by

reconfiguring the switch’s network startup.
This is detailed in the document: How_To_Change_A_TLX_Matrix_Switch’s_IP_Address.pdf.
The switch uses several network ports for control and status. Port 17567 accepts commands to control

the switch.
The command API is described in the manual: TLX_Matrix_Switch_ASCII_API_V5.pdf.
There are other ports that can be read to access system configuration and operating data. The actual

data format varies by model and is described in the following sections. There are five blocks of data
available for reading.

TLX24 Matrix Switch Product Manual thinklogical Rev. C, August, 2016

Page 11

These ports are documented in the manual: TLX_Switch _Interfaces.pdf.

1. Switch connection status (broadcast over port 17564 every few seconds)

 The primary CPU IP address
 First port number in this block
 Last port number in this block
 'N' port number values

2. Port settings (UDP port 17565, matrix switch localhost only)

 Port output level value
 Port input enable status
 Input port number (big-endian format)

3. Hardware sensor status (TCP port 17566)

 Reserved for future use.

4. Inventory and Power Supply Status (TCP port 17600)

 Card Inventory
 Power Supply Status (internal TL use only)
 Switch card temperature readings

5. I/O data (TCP port 17601)
Refer to the manual TLX_Switch _Interfaces.pdf.

6. Service Request (LOS) Signaling (UDP port 17560)
The TLX24 10G Matrix Switch can broadcast a message over the network when a remote receiver
requests attention. When enabled, the receiver will toggle its TX pin, causing a LOS (loss of signal)
event to occur at the switch. When detected, the switch broadcasts an 'Attention Request' message over
the network. This message contains the IP address of the switch and the port number that detected the
request. It is left up to an external system to detect, decode and act upon this request.

 32-bits, switch 's primary IP address
 16-bits, set to 0
 16-bits, port number (list starts from 1, not 0)
 16-bits, key code in bits 0 – 7, 0x00 and 0xff are ignored

SNMP SUPPORT

The switch can be monitored via SNMP Simple Network Management Protocol (supports version V2c

and V3 USM). Please call our technical support staff at 1-203-647-8700 for downloadable MIB
Management Information Base definition files.

There are certain entries in the SNMP configuration file (/etc/snmp/snmpd.conf) that users may wish
to modify:

 syslocation Text to aid in locating the unit
 syscontact Name/ Phone/ Email address of a contact
 trap2sink IP address/ Name of a system to receive SNMP traps

The default name used by trap2sink is 'snmp.trap' and is defined in the file /etc/hosts as pointing to

127.0.0.1. The easiest method to change the trap address is to modify the /etc/hosts entry and not
change the trap2sink setting in the configuration file. Users may have multiple trap2sink entries in the
configuration file to specify multiple trap destinations.

NTP SUPPORT

NTP, or Network Time Protocol, is used to keep the internal clock on the switch set to the correct
time. By enabling this service, users keep the switch’s clock synchronized to an external time reference.

In order to use the service users must have a time server running on their network or allow the switch to
access a public time server. NTP configuration is contained in the file /etc/ntp.conf

Details about NTP configuration may be found at:

http://tldp.org/LDP/sag/html/basic-ntp-config.html

SYSTEM LOG FILES SUPPORT

The switch records system events into files located in the directory /var/log/. If you wish to preserve
log files, you may redirect the logs to another system(s). This is a standard feature of Linux's rsyslogd
program. Redirection is enabled by entries in rsyslog configuration files located in /etc/rsyslog.d/

Details about syslog configuration file entries may be found at: http://www.rsyslog.com/doc/

SERIAL/RS-232 INTERFACES

Unpacking the TLX24 Matrix Switch

The TLX24 Matrix Switch is designed to be mounted in a standard EIA 19” rack. All physical

connections to the product use industry-standard connectors. Non-supplied cables that may be needed
are commercially available. All connections are found on the rear of the unit.

Step 1 Carefully remove the TLX24 from its shipping package and inspect it to make certain that it is

in good condition.

Step 2 Ensure that all the SFP modules are sealed with a removable dust plug.
Step 3 Verify that the power supply is fully seated in the chassis and that the locking latch is

secure.

Step 4 When the device has been inspected and found to be in suitable condition, the installation

process can begin.

Connecting to the TLX24 Matrix Switch

Thinklogical’s line of TLX Extenders come in both fiber-optic cable and CATx cable versions.

Thinklogical’s proprietary multiplexing technology combines video, audio and peripheral data on a single

data stream for up to 80km over a single fiber or up to 100m over a single CATx cable.

External Control CPU Minimum Requirements

The External Control CPU must meet the following minimum requirements (including requirements
for using Thinklogical’s System Management Portfolio):

 System Management Interface package requires Debian 32 or 64 bit.
 Configurator and Hot Key Manager run on Linux (RedHat 32 & 64 bit, Debian 32 & 64 bit or

Windows XP, 7, and 8).

 RAM (minimum): Linux: 1GB Windows: 4GB OSX: 4GB
 VIDEO: Works with all video adapters. (Not required if the computer is used as a headless server.)
 KEYBOARD/MOUSE: Works with any keyboard/mouse/touchpad. (Not required if the computer is

used as a headless server.)

 NETWORK: One port minimum, although two ports are recommended for security considerations.
 DISK SPACE: Thinklogical programs typically use less than 40 MB.
 SERIAL PORT: 1 optional RS-232 serial port (Crestron/AMX serial access)

Pluggable SFP+ Modules

Each Input and Output card contains rows of SFP+ modules that
serve as the fiber-optic couplers for the fiber cables to and from the
Thinklogical transmitter and receiver extenders. Individual cards can
be removed for easy access to the SFP+ modules.

The SFP+ Optical Module is an 8Gbs Short-Wavelength Transceiver
designed for use in bi-directional Fiber Optic Channel links. The
modules have LC-type connectors, are hot-pluggable and operate
on 3.3VDC.

Always use dust caps to protect against dust and damage when
a fiber optic connector is not attached to its coupling device
(fiber optic equipment, bulkheads, etc.). All Thinklogical Matrix
Switch SFPs are fully populated with dust plugs upon shipment.

Note: It is good practice to immediately install dust plugs in unused SFP modules and on

the ferrules of unconnected fiber-optic cables.

Each fiber-optic TLX24 has either 12 or 24 SFP+ Modules, each mounted within a grounded metal

enclosure. Each SFP is locked into its enclosure with a built-in latch handle that can be opened for
removal or locked for installation (right).

The latch handle spans the two LC ports. Arrows printed on the handle indicate which port is an INPUT
( ) and which is an OUTPUT ( ).

LC-Type Fiber Optic Cable

Installing Fiber Optic Cable: The TLX24

switching matrix connects any SFP’s optical
output port (Transmit) to any other SFP’s optical

input port (Receive).

Requirements: Thinklogical recommends SX+ Laser Enhanced (50µm) fiber with LC-type connectors

for your TLX24 KVM Matrix Switch and Velocity Extension System. Multi-mode fiber can extend up to a
maximum of 400m and Single-mode fiber can extend up to 80km.

Handling Fiber Optic Cable: Unlike copper cabling, fiber optic cable requires special handling.

A small speck of dust or a scratch to the ferrule tip (the end of the connector) can attenuate the
optical signal, rendering the cable inoperable.

Warning! The ends of the connectors

(the ferrule) should never come in

contact with any foreign object,

including fingertips. Always install a

dust cap immediately on the ferrule of

any unused fiber to protect the tip.

Dust cap installed on the ferrule.

Warning! Minimum bend diameter

must be no less than 3”. Be careful

not to kink or pinch the fiber when

using ties.

CATx Cable

There are currently several versions of CATx (category 5/5a/6/6a/etc.) cables with RJ-45 connectors on the
market. Thinklogical recommends 23 AWG Category 6a Cabling for TLX applications, which
operates over channel lengths of up to 100 meters. Assume a 30% derating for 26 AWG CAT6a cabling.

Routing Thinklogical Extenders through the TLX24

Comprised of a fiber-in, fiber-out matrix switch and fiber-optic or CATx Transmitter and Receiver
Extenders, this complete system provides transparent and secure routing, switching and extension of
video and high-speed data peripherals to remote destinations with ease.

Connecting to the Receiver

The Velocity Receiver serves as the Destination (desktops, theaters, conference rooms, editing

suites, control consoles, video walls, etc). Depending on your configuration, your KMASS devices (audio,
keyboard, mouse, etc.) are connected to the Receiver first, using standard cables. Power can then be
applied to the unit. The Receiver then connects to the TLX24 using fiber-optic cable (Multi-mode fiber for
distances up to 400m; Single-mode fiber for distances beyond 400m).

Connecting to the Transmitter

The Transmitter serves as the Source (computer and video entities). If the source includes a

workstation, depending on your configuration, your local KMASS devices (audio, keyboard, mouse, etc.)
should be connected first. The video sources (e.g. computers, tape decks, etc.) are connected next,
followed by any local video devices. Power can then be applied to the unit. The Transmitter connects to
the TLX24 Transmitter ports using fiber-optic cables (Multi-mode fiber for distances up to 400m; Single­mode fiber for distances beyond 400m).

Routing Thinklogical® TLX Extenders through the TLX24

Connecting to a Control CPU

The TLX24 is controlled via a dedicated external Control CPU. This allows for customization as well as
ease of control and administration. Access is provided via a network connection or serial RS-232 port.

Note: The Control CPU (Computer) is supplied separately.

The network and serial RS-232 connection both use the same low level ASCII API syntax. This
command syntax is defined in the document: Router_ASCII_API.pdf. Each line contains only one
command and must end with a carriage return (CR) and line feed (LF), or just a line feed (LF). The
characters are not echoed.

The serial port is configured for 9600 baud, 1 stop bit, no parity, and no flow control. The network
interface listens on TCP (Transmission Control Protocol) port 17567. It accepts the same commands as
the serial interface. You may use telnet to manually open a connection and control the TLX Matrix Switch
using port 17567.

Third-party controllers will control the Matrix Switch by connecting to either the serial or network port.
Using the network is the only means to take advantage of our automatic fail over facility.

Thinklogical offers a web-based control program called 'Configurator'. This program is described in
greater detail in the document: Manual_Sytem_Management_Portfolio.pdf, available on the
Thinklogical web site.

Firmware

Page 21

On Screen Display (OSD) - Firmware Option

The optional Configurator can be accessed and controlled via an OSD (On-Screen Display) technology.
The Configurator software can be installed on a designated out-of-band (OOB) PC which users can
access from a workstation. A preconfigured hot-key sequence will deliver the Configurator GUI straight
to the user’s desktop monitor. The user can then select the defined sources and destinations that they
wish to connect. While a user is making the connections, they have exclusive use of the OOB PC. Once
they have completed their connections, the OOB PC becomes available for the next user. The OOB PC
that has the Configurator loaded on it has a built in timeout function, therefore the PC should not be
taken out of service for an extended period of time. The timeouts can be set in increments of one
second. Typical timeouts are in the order of 10 seconds.

Appendix D: Secure Applications

Note: Restricted Switching and Partitioning security features are only available with
fiber-optic Matrix Switch applications. CATx Matrix Switching applications do not offer
the same level of security.

TLX Matrix Switch Control

When used in a secure application, the fiber-optic Matrix Switch and External Computer (server) used to
manage the system must be located in a physically secure environment to which only trusted
administrators have access. Similarly, the server used to manage the Matrix Switch must be physically
protected and have suitable identification/authentication mechanisms to ensure that only trusted
administrators have access.

Thinklogical’s TLX, VX and MX Matrix Switches use two methods for secure routing. One is known as

Restricted Switching and the other is known as Partitioning. These methods can be deployed
singularly or jointly, depending on security requirements.

TLX24 Matrix Switch Product Manual thinklogical Rev. C, August, 2016

Page 32

Restricted Switching

Restricted Switching provides multiple levels of security classification domains on the same
Matrix Switch. Each destination must ensure that no unauthorized content is displayed or accessed,

therefore, every input and output must be prioritized. Priorities can range from 1 to the total number of
ports in the Matrix Switch. An output can connect to an input with a priority greater than, or equal to, its
own. Thus, a priority level of 1 on an output can connect to any input (priority 1, 2, 3…).

The user must provide a table defining the priorities for each input and output of the switch matrix. This
table is in the form of a comma separated value (csv) file. This file contains the values in three columns:
Port Direction (i=input, o=output), Port Number and Port Priority. For example:

I/O Number Priority
"i", 1, 1
"i", 2, 2
"i", 3, 3
"i", 4, 1
"i", 5, 3
"o", 1, 1
"o", 2, 3
"o", 3, 2
"o" 4, 4
"o", 5, 1

Output 1 can connect to ports 1-5.
Output 2 can connect to ports 3 and 5.
Output 3 can connect to ports 2, 3, and 5.
Output 4 cannot connect to any ports.
Output 5 can connect to ports 1-5.

Note that Port Direction (i or o) is in quotes and that the table must use only the following ASCII printable
characters:

Double quotes character code = 34 (")
Lower case i character code = 105 (i)
Lower case o character code = 111 (o)
Comma character code = 44 (,)
Carriage Return character code = 13 (CR)
Line Feed character code = 10 (LF)

The Restricted Switching Table files for the TLX24 Switch are stored in the on-board Controller at:
var/local/router/restrict/upstream.csv

The on-board Controller will evaluate its Restricted Switching Table (upstream.csv file) only once at
boot-up.

Any errors that occur during the Restricted Switching Table evaluation process will be logged in the
daemon.log file at the following location: var/log/daemon.log

To verify the system restrict policy, Thinklogical recommends the following:

1) Review the daemon.log file and correct any errors in the Restricted Switching Table before
implementing multiple levels of security classification domains on the same Matrix Switch.

2) Fully test Restricted Switching before implementing multiple levels of security classification
domains on the same Matrix Switch.

There are cases where updates to the Restricted Switching Table must be made in an active
system. When an update is made to the table, the Controller will not evaluate the new table until it is

rebooted.
Restricted switching is disabled when Restricted Switching Table files are removed. By default,

when there are no Restricted Switching Table files, all input and output ports will have a priority of 1. All
Switches are shipped without Restricted Switching Tables and therefore do not restrict any connections.

Switch:

Restricted switching is configured via firmware loaded into
the Matrix Switch. The configuration file for this scenario
will appear like the table at right. 

Partitioning

Partitions allow TLX, VX and MX fiber-optic Matrix Switch sources and destinations to be
segregated. Therefore, destination work stations will only receive signals that are transmitted from

source computers in the same partition. In addition, it is impossible for a source computer to be
inadvertently routed outside of its designated partition as the signals will not be transmitted.

The user must provide a table defining the partitions. This table is in the form of a comma separated
value (CSV) file located in /var/local/router/partition. This file contains the port number and the
partitions to which it belongs. The configuration file for such a scenario looks like this:

Example: VX80 Switch with four distinct partitions:

Four partitions set up for secure routing and extension applications. Signals are only capable of

transmitting and receiving within a single partition and not across partitions

The maximum number of partitions is the number of ports that make up the Switch (12, 24, 80, 160, 320,

640). A VX80 Switch can be configured with up to 80 partitions, a VX160 up to 160, and so forth. There
are also overlapping partition configurations.

EXAMPLE: A VX80 with four partitions

The following example shows a VX80 Switch with an overlapping partition (Ports 5-10 are accessible to
both partitions 2 and 3):

The Partition Table files for the TLX24 are stored in the on-board Controller at:
var/local/router/partition/upstream.csv

TLX24 Matrix Switch Product Manual thinklogical Rev. C, August, 2016

Page 35

The Controller will evaluate its Partition Table (upstream.csv file) only once at boot-up.
Any errors that occur during the Partition Table evaluation process will be logged in the daemon.log file

at the following location on the Controller: var/log/daemon.log

Note: For access to the daemon.log file via SSH, refer to “THE NETWORK INTERFACES”
section of this manual (page 10).

To verify the system partition policy, Thinklogical recommends the following:

1) Review the daemon.log file and correct any errors in the Partition Table before implementing
multiple levels of security classification domains on the same Matrix Switch.

2) Fully test the Partitioning before implementing multiple levels of security classification domains
on the same Matrix Switch.

There are cases where updates to the Partition Table must be made in an active system. When an
update is made to the table, the Controller will not evaluate the new table until it is rebooted.

Partition switching is disabled when Partition Table files are removed. By default, when there are no
Partition Table files, all ports not listed will default to partition 1. All Switches are shipped without

Partition Table files and therefore do not restrict any connections.

Administration Access

There are only two methods by which the administrator can access the Switch Configurations:

1. Using the serial console directly connected to the Switch.

Note: While no administrator password is required to use the serial console, physical
access to the Switch is required, therefore the Switch should be stored in a physically
secure location to avoid unauthorized access.

2. Using SSH access

The Switch allows SSH connections to the Switch for management purposes. SSH sessions are
authenticated using an encrypted password file.

Password Security

For security purposes, the Switch defaults to using the Message-Digest Algorithm (MD5) and
shadow passwords. It is highly recommended that you do not alter these settings. If you
select the older Data Encryption Standard (DES) format, passwords will be limited to eight
alphanumeric characters (disallowing punctuation and other special characters) with a modest
56-bit level of encryption. The single most important thing you can do to protect the Switch

is create a strong password.
Creating Strong Passwords:

The password can contain up to 127 characters and cannot contain a space.
 MAKE THE PASSWORD AT LEAST EIGHT CHARACTERS LONG. The longer the password,

the more effective it will be. If you are using an MD5 password, it should be approximately 15
characters long. With DES passwords, use the maximum eight character length.

 MIX UPper AnD LowER CASE LETTERS. Passwords are case sensitive, so mixing will

multiply the number of possible combinations.

 MIX LETTER5 AND NUM8ERS within the password to enhance its strength.
 INCLUDE NON-ALPHANUMERIC CH@RACTER$. Special characters, such as (& $ % >) and

punctuation marks (? “- !) increase the strength of a password.

Secure Application Examples

The Diagram on page 37 shows the TLX24 Matrix Switch in a secure application. The highly secure
components are described as the Red Network and the other, lower security components are
described as the Black Network. The Red Network, containing the computers (sources), is shown in a

The configuration of the TLX Matrix Switch should be reviewed regularly to ensure that it
continues to meet organizational security policies concerning:

 Changes in the TLX Matrix Switch configuration
 Changes in the organizational security policy
 Changes in the threats presented from non-trusted network interfaces
 Changes in the administration, operation staff or the physical environment of the TLX Matrix Switch

physically secure environment along with the TLX Matrix Switch, the computer server used to manage
the Switch, and the Network Hub. The Network Hub is a dedicated network used only to connect the TLX
Switch to the computer server. This dedicated network does not connect to any other components and
does not extend beyond the physically secure environment. The dedicated network connection may be
replaced by a direct serial connection (RS-232) between the TLX Switch and the computer server.

The TLX Matrix Switch can be configured to
prevent accidental connection from the Red
Network to the Black Network using the
Restricted Switching feature. For example, the

TLX Matrix Switch Network Diagram should be
configured with the following csv file:

The following connection rules apply: SOURCE 2 can be connected only to DESTINATION 2 and
SOURCE 1 can be connected to both DESTINATION 1 and DESTINATION 2.

Note: The TLX Matrix Switch and the computer server used to manage the Switch must be
protected according to the highest security classification of any component in the entire
network application.

Note: The optical connections and DESTINATION receiver designated as Red Network
must be physically secure.
