S6* Waiting period dial tone
Maximum waiting time for the dialing tone. After the modem went off-hook it
waits 7 seconds for the dialing tone (fixed for approval purposes). If it detects a
dialing tone during this waiting period it will start dialing.
If it does not detect a dialing tone, it will check if dial tone recognition is activated
or if the dialing string (Chapter „AT Command Set“, command ATD) contains the
parameter W. If the dialing tone detection is not activated, the modem waits for
the dialing tone. The waiting time (in seconds) is specified in S6.
The value of the S6 registry can be between 4 and 7 seconds.
S7* Waiting period carrier signal
Wait for the carrier frequency from the other modem. The maximum time for the
modem to wait for a response from the other modem is specified in S7. The time
starts running as soon as the modem has finished dialing. The value of S7 can be
between 0 and 180 seconds.
S8* Dial tone delay
Dial pause time, if a comma is included in the dialing string. If there is a comma in
the dialing string, the modem will wait during the dialing procedure, until the
time specified in S8 (in seconds) has run out. The value of S8 can be between 1
and 7 seconds.
S9* Reaction time carrier signal
DCD response time for the carrier frequency from the other modem. The DCD out-
put of the RS232 interface (CT109) of the modem switches to ON, when the carrier
frequency from the other modem is detected before the time defined in S9 (in
tenth of seconds) runs out. S9 must be smaller than S10.
S10* Time period between lost carrier signal and hang up
The time which leads to termination after carrier frequency loss. In S10, the time
is specified in tenth of seconds, which the modem awaits to disconnect, if it can’t
detect the carrier frequency from the other modem anymore.
S12* Transmission clock of the ESC characters
Minimum pre and post run time and maximum interim time in 1/50 of seconds
between two characters. This must be observed, if the modem is supposed to de-
tect an abort sequence (usually +++).
