Description

 

 

 

 

 

Volume Selection: This command sets the volume level for the modem’s playback voice mode. A

 

 

different playback level may be needed for each type of playback device (telephone line, local handset,

+VGT=m

128

local telephone, or speaker).

 

 

 

 

Range: 121–131

 

 

128*

Nominal transmit level

 

 

 

+VIP

none

Initialize Parameter: This command causes the modem to initialize all voice parameters to the factory

default values. This command does not change relay or speaker setup (that is, if the modem is off-

 

 

hook, then the modem remains off hook after processing this command).

 

 

 

 

 

DTE/DCE Inactivity Timer: This command sets the length of time the modem can be inactive in voice

 

 

mode before the modem resets its relays +VLS=0 and changes to data mode (FCLASS=0) with

 

 

autobauding. The purpose of this timer is to ensure that the DTE does not leave the DCE in a mode

 

 

that cannot be accessed by voice-unaware software. This timer is supported in playback, record and

+VIT=m

0

voice command mode. Sending any data (such as a <DLE><NUL> string) to the modem re-initializes

this timer.

 

 

 

 

 

 

Range: 0–255 (units of 1.0 second)

 

 

m = 0*

Disables inactivity timer

 

 

m ≠ 0

Inactivity timer active
