Initialize Parameter: This command causes the modem to initialize all voice pa-

rameters 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).

+VIT=n 0

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 ac-

cessed by voice-unaware software. This timer is supported in playback, record

and voice command mode. Sending any data (such as a <DLE><NUL> string) to

the modem re-initializes this timer.

n =0–255 (units of 1.0 second)

n = 0* Disables inactivity timer

n ≠ 0 Inactivity timer active
