Multi-Tech Systems MVPGSM-2 Regional Parameter Definitions, Standard Tones fields, Default -16dB

				Chapter 4: Configuring your MVPGSM
		“Regional Parameter” Definitions
Field Name	Values	Description
Country/Region	USA,	Name of a country or region that uses a certain set of tone pairs for dial tone, ring
	Japan,	tone, busy tone, unobtainable tone (fast busy tone), survivability tone (tone
	UK,	heard briefly, 2 seconds, after going off hook denoting survivable mode of VOIP
	Custom	unit), re-order tone (a tone pattern indicating the need for the user to hang up the
		phone), and intercept tone (a tone that warns a party that has gone off hook but
		has not begun dialing, within a prescribed time, that an automatic emergency or
		attendant number will be called; the automatic call can be used to direct an
		attendant’s attention to a disabled or distressed caller, allowing an appropriate
		response to be made).
		In some cases, the tone-pair scheme denoted by a country name may also be used
		outside of that country. The “Custom” option (button) assures that any tone-
		pairing scheme worldwide can be accommodated.
		Note 1: Intercept tone is applicable only when the FXS telephony interface has
		been chosen in the Interface screen and when the AutoCall / OffHook Alert field is
		set to OffHook Alert in the Voice/Fax Parameters screen. The time allowed for
		dialing before the automatic calling process begins is set in the OffHook Alert
		Timer field of the Voice/Fax Parameters screen.
Advisory screen				This message screen appears whenever the
				Country field is changed. It informs the operator
				that, upon change of the Country field value, all
				User Defined Tones will be deleted.
Standard	Tones fields
Type column	dial tone,		Type of telephony tone-pair for which frequency, gain, and cadence
	ring tone,		are being presented.
	busy tone,
	unobtainable tone,
	survivability tone,
	re-order tone
Frequency 1	freq. in Hertz		Lower frequency of pair.
Frequency 2	freq. in Hertz		Higher frequency of pair.
Gain 1	gain in dB		Amplification factor of lower frequency of pair.
	+3dB to –31dB		This applies to the dial, ring, busy and ‘unobtainable’ tones that the
	and “mute” setting		MultiVOIP GSM outputs as audio to the wireless port. Default: -16dB
Gain 2	gain in dB		Amplification factor of higher frequency of pair.
	+3dB to –31dB		This applies to the dial, ring, busy, and ‘unobtainable’ (fast busy) tones
	and “mute” setting		that the MultiVOIP GSM outputs as audio to the wireless port.
			Default: -16dB
Cadence	n/n/n/n		On/off pattern of tone durations used to denote phone ringing, phone
(ms) On/Off	four integer time		busy, connection unobtainable (fast busy), dial tone (“0” indicates
	values in		continuous tone), survivability, and re-order. Default values differ for
	milliseconds; zero		different countries/regions. Although most cadences have only two
	value for dial-tone		parts (an “on” duration and an “off” duration), some telephony
	indicates continuous		cadences have four parts. Most cadences, then, are expressed as two
	tone		iterations of a two-part sequence. Although this is redundant, it is
			necessary to allow for expression of 4-part cadences.
Custom (button)	Only available when		Click on the “Custom” button to bring up the Custom Tone Pair
	Country/Region is		Settings screen. This screen allows the user to specify tone pair
	set to “Custom”		attributes that are not found in any of the standard national/regional
			telephony toning schemes.
