Tone time per digit for DTMF-signalling
Determines the tone time per digit in milliseconds.
Value = 0 - 255
NOTE: Tone time = 0 gives continuous tone
transmission (of first keyed digit).
Intended for use when measuring the
DTMF-signal.
2010
Interdigital pause for DTMF-signalling
Determines the interdigital pause for DTMF-signalling.
Value = 20-255
2026
Attenuation for DTMF-signals
The attenuation level of DTMF-reception can vary from
market to market. The ELU-A/MFU board has
therefore been designed with programmable
attenuation level.
261x
DTMF-tones
The following commands are used for the
programming of DTMF-tones:
• 2610 Number of DTMF
• 2611 Level (dBm0)
• 2612 Level difference (dBm0)
• 2613 Signal time (ms)
• 2614 Pause time (ms)
2610
Number of DTMF
This command determines the number of DTMFs to be
12 or 16. If the number of DTMFs is 16, the maximum
number of tone fragments is 15. If the number of
DTMFs is 12, 19 tone fragments are possible (see
command 2601).
2611
Level (dBm0)
This command defines the level of the high frequency
group for DTMF.
Value: -64.0 - +3.0 dBm0 in steps of 0.5 dBm0
2612
Level difference (dBm0)
This command determines the difference in level
(dBm0) between high and low frequency groups in
DTMF-sending.
Value: 1 - 3 dBm0 in steps of 0.5 dBm0
2613
Signal time (ms)
This command defines the tone time per digit for digit
sending with DTMF.
Value: 0 - 32768
N.B.: Tone time = 32768 means continuous tone
sending (of first entered digit). Intended for use
when measuring the DTMF-signal.
2614
Pause time (ms)
This command defines the interruption time between
the digits at digit sending with DTMF.
Value: 0 - 32768
N.B.: Pause time = 32768 means silence.
