13 APPLICATION EXAMPLES

In this chapter some application examples are given to assist users with the programming of the PCD5096

(DSP parameter settings, control register settings and IOM-2 interface programming). Three examples are considered:

a two channel application, a conference call application between one PSTN line and two IOM buffers, and a conference

call application between two PSTN lines and one IOM buffer.

13.1

PCD5096 with two active channels

A typical application for the PCD5096 is depicted in Fig.22. Two handsets (PPa and PPb) are connected through a

PCD5093 and a PCD5096 to two PSTN lines. Tables 35, 36 and 37 show possible settings for the DSP parameters, the

IOM control table and the control registers in the PCD5096.

Note that the chosen values for the IOM pointers, the volume parameters and the frequency parameters depend on the

application. This means that they can differ from the values that are given in this example.
