4.10 DTMF/MF ANALYZE 3
This is the third of three menus used for Tone dialing analysis. These menus apply to
DTMF
,
and
MF(R1)
. This menu contains parameters used to set Tone ON and OFF time thresholds
and Guard Time.
DTMF/MF :
ANALYZE 3: TONE ON/OFFms(min)
35 35
* 25 to 99 (1ms steps)
Alternate:
GUARDms
40
0 to 99 (1ms steps)
* min ON time setting for DTMF = 25 ms
* min ON time setting for MF(R1) = 35 ms
4.10.1
TONE ON/OFFms(min):
When Tone Dialing is received, the
ON
time (time the digit is
present) and
OFF
time (quiet time between digits) must be greater than the setting of
these values. If either the
ON
time or the
OFF
time exceed these settings, the Event is
flagged as an error.
4.10.2
GUARDms:
When a Tone is present, this parameter controls whether or not the AM8a
will analyze it. This
GUARD
(Tone
ON
time) time MUST be exceeded before the
AM8a will analyze it. If the Event is shorter, it will be ignored.
4.11 THRESHOLD ANALYZE
This menu controls the Tone Level and the Off Hook threshold that the AM8a will recognize.
OFF HKvdc(min)

2 to 60 (1 vdc steps)
THRESHOLD:
ANALYZE : TONEdBm(min)
-30
-40 to 0 (1 dB steps) Alternate:
4.11.1
TONEdBm(min):
When a Tone is present, this parameter determines the
LEVEL
which
must be exceeded before the AM8a will analyze it. If a Tones Level is below this
setting, the AM8a will ignore it.
