VX 40 Router KVM Matrix Switch
The TOE is a distributed system, which allows for remotely operation of shared computers using sets of
shared peripherals, dynamically connecting (switching) physical ports on a particular computer to a
particular shared peripheral set.
The TOE consists of the following hardware devices:
- Thinklogical KVM Matrix Switch.
VX 40 Router and a customer supplied computer system (CSCS)
A set of Thinklogical Velocity Transmitter Extender Devices connected to sets of peripheral ports on shared computers.
A set of Thinklogical Velocity Receiver Extender Devices connected to sets of shared peripherals
Velocity Transmitter Extenders are connected to Transmitter Port Groups on the Switch using optical
fibers connections. Transmitter Port Groups are marked green on the VX40 Switch.
Velocity Receiver Extenders are connected to receiver port groups on the Switch using optical fiber
connections. Receiver Port Groups are marked blue on the VX40 Switch.
Each Transmitter and Receiver Port Group is composed of two ports: transmit (T) port and receive (R)
port. Two optical cables are then required to connect a Velocity Transmitter or Receiver Extender to a
Transmitter or Receiver Port Group on the Switch. One cable is used to transmit data from the Extender
to the Switch; the other cable is used to transmit data from the Switch to the Extender. As a result, a bidirectional
connection is established, where data can flow in both directions.
All data types, including video, audio and serial data are converted to an optical form and transmitted
in a single optical cable.
The purpose of the Switch is to establish logical connections between Transmitter and Receiver Port
Groups, while preserving Data Separation Security Function Policy (SFP).
