Large business systems
For large business systems, local loop and public access systems, several PCD5096 codecs can be connected together
utilizing the serial bus system. A digital cordless base station for large business systems typically consists of a baseband
processor, radio interface and a number of universal codecs interfacing to local lines, PSTN lines and to the local corded
handset/hands-free interface. A diagram of this configuration is shown in Fig.20.
The universal codec can connect to different applications in a typical large business system. They are as follows:
1.
PSTN Line Interface
2.
Speaker phone with hands-free feature
3.
Local Line Interface.
In these applications the additional processing required for conference calling is performed either in the host baseband
processor, or in the universal codecs.
For further details about these three applications consult the “PCD5096 DSP user manual”
