Chapter 4: Configuring your MVPGSM

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.

Description

Identifies the type of telephony signaling tone for which frequencies are being specified.

About Defaults: US telephony values are used as defaults on this screen. Lower frequency of pair.

Higher frequency of pair.

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

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

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 is duration of first “off” period in signaling cadence. Cadence 3 is duration of second “on” period in signaling cadence. Cadence 4 is duration of second “off” period in the signaling cadence.
