56K V.92 Data, Fax, and Voice Chipset

Table 7-1. S-Register Command Descriptions (Continued)

Disconnect Inactivity Timer: This S-register sets the length of time (in minutes) that the modem stays online/off-hook before disconnecting when no data is being transmitted or received. In data and fax modes, any data transmitted or received be- tween the DTE-DCE interface resets the timer. In all other modes (except Tele- phone-Emulation mode), any data transmitted resets the timer. In Telephone-Emu-

S30 0 lation mode, S30 is ignored (that is, the modem does not automatically hang up the line after a given time delay).

Range: n = 0–255 minutes

n = 0

Disabled
