23 ~ 2000 ms This setting is the minimal time setting to
distinguish DTMF tones for the IPLB. If the
signal is shorter than the value set, the sig-
nal is deemed not a DTMF.
0: -40dbm This setting is the minimal level setting to
1: -39dbm distinguish DTMF tones. If the signal is
2: -38dbm shorter than the value set, the signal is
: deemed not a DTMF.
31: -9dbm
0: -9db This is a frequency ratio setting of the
1: -8db DTMF for the frequency other than the
: DTMF tone. When this value comes to
6: -3db 0db, the DTMF is distinguished only when
7: -2db the signal level except DTMF is low. In
8: -1db case of wrong DTMF detection by a per-
9: 0db son's voice, there is the possibility that the
level except DTMF is large. The system
will be able to protect a wrong DTMF de-
tection by choosing 0db value or so.
