• Manufacturer Part Number: ml7214a-001
• Description: Voip Codec
• Manufacturer: Oki Semiconductor

Configuration Example 5 (Three-Way Speech: Terminal Side [One Party] – NW Side [Two Parties])
This configuration example shows when three-way speech is performed among an analog phone (A-TEL)
connected to the terminal side and the network side (two parties).
Please be aware that three-way speech cannot be performed among the terminal side (one party) and the network
side (two parties) between CH0 and CH1. In this configuration example, the CH1 side shows when the basic
speech is performed.
(1) Use of analog interface
Setting Examples
• CR10=06h (CH0/CH1 terminal interface: Analog interface, VFRO0/VFRO1=Voice output)
• CR13=12h (Frame/16B/G.711 µ-law/10msec)
• CR6=03h, CR7=8Bh, CR8=00h, CR9=08h, CR1=80h
* When the decode output start offset time is 1 msec
• CR24=04h (G711_PLCEN=“1”)
• Various settings
• CR0=01h (LONG/OPE_STAT=“1”)
• CR24=ECh (SC_CH0aEN=SC_CH0bEN=SC_CH1aEN=DEC_OUTON=G711_PLCEN=“1”)

(Caution) Restric tions on functions common to CH 0/CH1
* When t he FS K detector (FS K , DE T ) is used, it is prohibited to use DTMF detec tor
0 (DTMFDE T 0) or DTMF detec tor 1 (DTMFDE T 1).
* When the DP GE N is used, it is prohibited to use the FS K generation function and
tone generation function of either channel .
(Caution)
A function whose use is prohibited or a function with restrictions is indicated by
