INTRODUCTION
The C400xr ISDN audio codec has been designed for the broadcast of high quality audio over
the ISDN and other digital networks, such as Switch-56, dedicated digital lines, optical fibre
networks, digital microwave links, satellite links, etc. To achieve an efficient utilisation of
the available network data bandwidth, the C400xr uses apt-X
TM
100 4:1 fixed audio compres-
sion / decompression system to provide full duplex, point-to-point audio transmission.
