Chapter 4: Configuring your MVPGSM
Multi-Tech Systems, Inc. MVPGSM 39
Setting Custom Tones and Cadences (optional). The Regional Parameters dialog box has a secondary dialog box
that allows you to customize DTMF tone pairs to create unique ring-tones, dial-tones, busy-tones or
“unobtainable” tones or “re-order” tones or “survivability” tones for your system. This screen allows the user to
specify tone-pair attributes that are not found in any of the standard national/regional telephony toning
schemes. To access this customization feature, click on the Custom button on the Regional Parameters screen.
The “Custom” button is active only when “Custom” is selected in the Country/Region field.

and “mute” setting
Amplification factor of lower frequency of pair. This figure describes
amplification that the MultiVOIP GSM applies to outbound tones entering
the MultiVOIP GSM at the input port. Default: -16dB
Gain 2 +3dB to
–
31dB
and “mute” setting
Amplification factor of higher frequency of pair. This figure describes
amplification that the MultiVOIP GSM applies to outbound tones entering
the MultiVOIP GSM at the input port. Default: -16dB
Cadence 1 integer time value in
milliseconds; zero value
for dial-tone indicates
continuous tone
On/off pattern of tone durations used to denote phone ringing, phone
busy, dial tone (“0” indicates continuous tone) survivability and re-order.
Cadence 1 is duration of first period of tone being “on” in the cadence of
the telephony signal.
Cadence 2 duration in milliseconds Cadence 2 is duration of first “off” period in signaling cadence.
Cadence 3 duration in milliseconds Cadence 3 is duration of second “on” period in signaling cadence.
Cadence 4 duration in milliseconds Cadence 4 is duration of second “off” period in the signaling cadence.
