be programmed to search for individual tones. The four
detectors have center frequencies which can be set by
registers UDFD1–4 (see Table 24). (SE5[6] [TDET]
[SE8 = 0x02] Read Only Definition) can be monitored,
along with TONE, to detect energy at these user-
defined frequencies. The default trip-threshold for
UDFD1–4 is –34 dBm but can be modified with the DSP
register UDFSL.
By issuing the “ATDT;” command, the modem will go off
hook and return to command mode. The user can then
put the DSP into call progress monitoring by first setting
SE8 = 0x02. Next, set SE5 (DSP2) = 0x00 so no tones
are transmitted, and set SE6 (DSP3) to the appropriate
code, depending on which types of tones are to be
detected.
