4.8 DTMF/MF ANALYZE 1

This is the first of three menus used for Tone dialing analysis. These menus apply to DTMF,
MF(R1), and MF(R2). This menu contains the parameters used to set the Low Band and HI
Band thresholds.
MF(R1) digits will not be seen if DIALTONE is used as a Start Signal.
NOTE:
DTMF/MF :
ANALYZE 1:
Alternate:
4.8.1 LO BANDdB(min/max): When Tone Dialing is received, the Lo Band LEVEL must fall
within the min and max settings of this parameter to be valid. If the Level is outside of
the programmed range, the Event is flagged as an error.
4.8.2 HI BANDdB: When Tone Dialing is received, the Hi Band LEVEL must fall within the
min and max settings of this parameter to be valid. If the Level is outside of the
programmed range, the Event is flagged as an error.

4.9 DTMF/MF ANALYZE 2

This is the second of three menus used for Tone dialing analysis. These menus apply to
DTMF, and MF(R1) frequencies. This menu contains the parameters used to set the Frequency
offset and Twist thresholds. For information on tone frequencies, refer to the description and
tables on the next page.
MF(R1) digits will not be seen if DIALTONE is used as a Start Signal.
