Introduction

For the first time, VideoJet X.21/G.703 implements live video
transmission on an existing X.21/G.703 leased line. Efficient compression, according to the ITU-T standard H.261, enables video
communication on any X.21/G.703 leased line.
VideoJet X.21 only has to be connected to the DCE terminating
adapter (DCE = data circuit-terminating equipment) of the X.21
port. The transmission speed is automatically adapted to the data
transmission rate of the line and ranges from 64 Kbit/s to 2.048
Mbit/s. The device is ready for operation on delivery. A terminal program is supplied for additional configuring.
VideoJet G.703 only has to be connected to the DCE terminating adapter (DCE = data circuit-terminating equipment) of the
G.703 interface. The transmission speed is automatically adapted
to the data transmission rate of the line (2.048 Mbit/s). The device
is ready for operation on delivery. A terminal program is supplied for
additional configuring.
This chapter will familiarize you with the underlying concept of the
VideoJet X.21/G.703 multimedia gateway. It will provide an
overview of the features and will give examples of typical applications. After an introduction to the front and back panel connectors,
you are in a good position to follow the installation and configuration
details given in the subsequent chapters.

Introduction
X.21/G.703 Transmission Concept
Until now, video and audio signals have been transmitted along
dedicated lines, e.g. coaxial cable. To make use of existing digital
networks and the simpler installation that entails, devices are
required to convert broadband analog video and audio signals for
existing transmission lines. The main advantage clearly lies in the
virtually unlimited loss-free transmission distance between sender
and receiver. The digitized video live image is transmitted across an
X.21/G.703 transmission line with the VideoJet X.21/G.703.

The VideoJet X.21/G.703 transmission system was designed,
to enable multimedia data streams over an existing X.21/G.703
leased line. It combines state-of-the art compression technology
with ease-of-use, enabling you to transmit full colour live video with
accompanying full-duplex audio and data over a X.21/G.703 leased
line.
The VideoJet X.21/G.703 functions as a DTE (data terminal
equipment). An adapter used as the line termination for the X.21/
G.703 leased line must therefore be used as the DCE (data circuit
terminating equipment).
The X.21 port of the VideoJet X.21 is directly connected to this
termination. The transmission rate matches the clock output by the
DCE (data circuit-terminating equipment). It can be anything from
64 Kbit/s to 2.048 Mbit/s (x times 64 Kbit/s, where x must not be
greater than 32).

VideoJet X.21/G.703 Manual
Introduction
The G.703 port of the VideoJet G.703 is directly connected to
this termination. The transmission rate is always 2.048 Mbit/s.
Also X.21/G.703 dial-up networks exist, when the connection is
established by dialling. However, the VideoJet X.21/G.703
operates on the basis of a X.21/G.703 leased line for which the
function for establishing the connection via a dial-up connection is
not supported.
VideoJet X.21/G.703 is available in two versions, as a
VideoJet
XS/GS
sender or as a VideoJet
XE/GE
receiver. The
sender links every PAL or NTSC video source at that side, which is
being monitored to the X.21/G.703 transmission port. The receiver
displays the video image on any standard PAL or NTSC monitor on
the receiving end of the X.21/G.703 leased connection. Remote
control of peripheral components like pan/tilt/zoom cameras is facilitated by the bidirectional serial interface.
With the audio option, bidirectional transmission of audio signals
across the X.21/G.703 leased line is also possible. An additional “A”
in the name indicates that the audio option is included. For example, VideoJet

Introduction
Front Panel Connectors
One of the VideoJet X.21/G.703 benefits is compact design,
enabling you to install the unit in the most confined environments,
e.g. installation ducts or camera housing. Compact design was
made possible in part by placing connectors at the front and the
rear panel. The front panel connectors are dedicated to the media
interfaces, i.e. video, audio and data, and are depicted in Fig. 2-4:

The green power LED will be lit as soon as power is supplied to the
unit and the unit is ready for service. During an active connection to
a VideoJet X.21/G.703 unit, the LED will blink to indicate the
connection status.
The serial interface for transparent data transmission does only
provide serial send (pin 3) and receive (pin 2) signals and ground
(pin 5). No hardware flow control signals are provided.
The handset interface facilitates direct connection of a telephone
handset.
Note that either the handset or the line interface is active at any
given time. Selection of the interface is described in Chapter 5.

Introduction
Rear Panel Connectors
On the rear panel of the unit you will find the X.21/G.703 network
interface, a terminal port for configuration and management with
the NCTerminal program, an I/O-port and the power connector:

(1) X.21 interface (DTE, 15-way SUB-D) for connection with
X.21 DCE
(2) Serial interface for configuration (NCTerminal, RS-232)
(3) Signalling input and relay output
(4) Power connector for connecting the AC plug power adapter

The power LED on the VideoJet X.21 is the only display that
supplies information about the connection status. But it can be
monitored with the terminal program included in the scope of supply. More detailed information is given in Chapter 5. Most of the
DCEs (data circuit-terminating equipment) of an X.21 leased line
are also equipped with a display that indicates whether data are
being transmitted through the X.21 port.

The green LINK LED will provide ISDN status information: If the
LED is on, the ISDN port is properly connected to the ISDN network.
The yellow TX (Transmit) LED will blink for each packet being transmitted. Note that packet reception is not signalled.
The RS-232 interface allows for connection to the serial port of a
PC for simple configuration or for the control of the VideoJet
X.21/G.703 unit. The interface features the full suite of RS-232
flow control signals.
The switching I/O-port allows for direct connection of external signalling devices, for example buttons or contacts. Also, the relay output facilitates switching of peripheral devices, for example lights or
electric door openers.

Introduction
Note: Use only the supplied AC plug power adapter. If the adapter,
the cable or the connector show any sign of damage, do not use the
power adapter and send it in for repair or replacement. Never
attempt to interface any other power adapter other than the supplied one.
