S-Register 11 – DTMF Tone Duration
S-Register 11 defines the duration/spacing of tones (in milliseconds) in Dual Tone Multifrequency
(
DTMF
) dialing. This register has no meaning unless the Tone Length option under the DIALING
OPT’S is set to S11. Refer to Appendix C, Country-Specific Information, for the ranges supported by
each country.
S-Register 12 – Escape Code Guard Time
The S-Register sets the interval that must be present on either side of the escape code (+++) in order
for the modem to recognize the escape command and enter command mode. This prevents the +++
characters from putting the modem in command mode if they are contained in data. The value of S-
Register 12 is multiplied by 0.02 to determine the number of seconds. For example, the value of the
factory default 50 is one second.
If S-Register 12 is set to 0, the speed at which you enter the escape sequence is not a factor.
S-Register 18 – Test Timer
This S-Register determines the duration, in seconds, of loopback tests. With S-Register 18 set to 0, the
timer is not operational and tests must be terminated manually.
NOTE
: S-Register 18’s function is
valid only when loopback tests are issued using the AT&T command. S-Register 18 cannot be used to
automatically terminate loopback tests if the test is initiated from the front panel.
