• Manufacturer Part Number: ml7084-001
• Description: 4ch Voip Codec
• Manufacturer: Oki Semiconductor

Configuration Example 1 (three-way calling: one person on the terminal side, two persons on the network
side)
This configuration example shows a case of calling made by three persons: one person (Mr. A) on the terminal side,
two persons (Mr. B and Mr. C) on the network side.
To make a three-way calling in this configuration, control the speech path switch using the following settings:
R1_TXON_a (CR44a-B5) = 1, R1_RXON_a (CR44a-B4) = 1
R0_TXON_a (CR44a-B1) = 1, T0_TXON_a (CR44a-B3) = 1
