V.34bis Series Standalone & Rackmount Modems
Timers
These modems have several timers that control the connection to the
phone line and the modem-DTE connection.
> Command Mode Inactivity Timer:
In Command Mode, if the
carriage return <CR> is not entered within 30 seconds after the AT
entry, the command that follows is ignored. To resume work, you must
enter AT again to wake up the modem.
> Online Inactivity Timer:
If no data is transferred for the period of
time specified in S-Register 32, the modem will automatically
disconnect from the telephone line. The inactivity can be related to
transmit data only, receive data only or to both as determined by the
AT%In command - see Chapter 6. The default is for the inactivity timer
to be disabled, AT%I0. Also, if S32 set to 0 the inactivity timer is
disabled. S32 may be zero or set to a positive value of 1-255 minutes
(asynchronous mode only).
> Abort Timer:
If no carrier tone is detected within the time period
specified in S-Register 7, the modem will drop the line. The default
time period is 60 seconds.
> Loss of Carrier:
If the modem loses carrier, it will disconnect from
the telephone line after the period of time specified by S-Register 10.
The default is 2.0 seconds.
