| CDTS-2048 | Copper wire Distributed Transmission System |
| Introduction |
|
The CDTS-2048
system enables computer systems to be connected by means of copper cables
over long distances at high data rates. The system was specially designed
for high-speed data transmission over long stretched networks such as common
alongside motorways and railways. The transmission system is based on 2-wire
SDSL technology and creates a transparent backbone network for devices
equipped with an Ethernet port.

| Description |

The CDTS
system offers a unique means for simplifying high-speed communication alongside
motorways and railways. In such environments usually one master station
interrogates multiple remote stations. When using the traditional multipoint
network system to address the remote stations, the communication is handled
by means of a special, non-standard, communications protocol, which has
to be implemented in all attached information systems. This implementation
usually is quite cumbersome and time consuming. The CDTS Network system
however, facilitates standard Ethernet protocols as supported by various
machines ranging from Personal Computers to advanced industrial computer
systems and video surveillance systems. Multiple CDTS units can be linked
together to build a wide area network alongside motorways, railways or
similar infrastructures.
In other
words: A CDTS network can be seen as an Ethernet LAN, which is spread out
over a wide area.
 The Ethernet
protocol allows all attached devices to send data without the intervention
of a master station. Nowadays many industrial computer systems are equipped
with TCP/IP networking facilities and standard Ethernet interfaces. This
enables such equipment to communicate in a standardized manner, which is
essential for compatibility between systems from different vendors.
The CDTS
system uses a reliable SDSL transmission technology in combination with
an efficient statistical multiplexing system to distribute the data packets
of each station over the network. For the connection between the stations
only one single copper wire pair is needed. The maximum distance between
the stations depends on the transmission rate and copper wire diameter.
The CDTS
unit offers a standard 10baseT Ethernet interface to attached systems or
Ethernet Local Area Networks. Because of the transparency of the system,
the need for configuration of each unit is kept to a minimum.
The CDTS
units are equipped with a bypass system that automatically creates a direct
connection between the next upstream and downstream CDTS systems should
the power of an intermediate CDTS fail.
For building
a fail-safe network system, a second cable (e.g. at the other side of the
rail or motorway) can be used to create a back-up network.
The CDTS back-up unit connects the two systems at each location and automatically selects an alternative route should one cable section or CDTS unit fail. Switching over between the regular and the back-up network section takes place within 3 seconds; short enough to maintain TCP/IP connections.
The network built with the CDTS system also allows forking, so connection to “side-tracks” can be made easily. For alarm
reporting and remote status reporting the CDTS units support the SNMP,
Telnet and HTTP internet protocol. The unit can be configured to send SNMP
traps (alarms) to a central Network Management station such as IBM Tivoli
or HP OpenView. For character-based access of the internal Modem Management
unit the internet Telnet Protocol can be used. The built-in web server
can be accessed by means of a standard Web Browser but can also be used
for a Graphical User Interface to be integrated in the Network Management
station.
