VideoJet X.21/G.703

Manual

Introduction

2

For the first time,

VideoJet X.21/G.703

implements live video

transmission on an existing X.21/G.703 leased line. Efficient com-
pression, 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 pro-
gram is supplied for additional configuring.

VideoJet G.703

only has to be connected to the DCE terminat-

ing 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 applica-
tions. 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.
