Command Default

Description

Compression Method Selection: (cont.)

<sel> Silence Expansion: This command enables the DTE to modify the amount of silence expansion. This parameter represents the maximum period of silence the DCE expands a period of silence compressed by the <scs> parameter. The DCE ignores the <sel> parameter if <scs> is zero.

NOTES:

1.Because of the high UART data rates, these compression/sample rates may not be applicable to the serial host interface (that is, serial box modem) designs (see ATI5 to determine if the modem is using the serial host interface). For parallel and PC Card host interfaces, the modem ignores the UART data rate.

2.DTMF detection is provided for all sample rates.

 

 

Speakerphone On/Off Control: This command turns on the speakerphone function. This feature

 

 

provides full-duplex speakerphone capabilities with internal adaptive echo cancellers. This command

 

 

takes the received voice signal and loops it back to the analog transmit pins. The host must configure

 

 

the relays and microphone interface as necessary using the AT+VLS=m command. Typically, this

 

 

means setting the off-hook relay driver, speaker, and microphone inputs with AT+VLS=13.

+VSP=m

0

After enabling the speakerphone mode (+VSP=1), the modem remains in voice command mode and

provides information about local off-hook detection, DTMF detection, and tone detection—if supported

 

 

 

 

by the modem board.

 

 

Range: 0, 1
