• Description: 4ch Voip Codec
• Manufacturer: Oki Semiconductor

Configuration Example 4 (three-way calling: three persons on the terminal side)
This configuration example shows a case of calling made by three persons (Mr. A, Mr. B and Mr. C) on the terminal
side.
To make a three-way calling in this configuration, control the speech path switch using the following settings:
R1_RXON_a (CR44a-B4) = 1, T0_RXON_b (CR44b-B2) = 1
