Voice/Fax Parameter Definitions (cont’d)

Field Name	Values	Description
DTMF Parameters
Duration	60 – 3000	When DTMF: Out of Band is selected, this
(DTMF)	ms	setting determines how long each DTMF
		digit ‘sounds’ or is held. Default = 100 ms.
		Not supported in 5.02c BRI software.
DTMF In/Out	Out of	When DTMF Out of Band is selected, the
of Band	Band, or	MultiVOIP detects DTMF tones at its input
	Inband	and regenerates them at its output. When
		DTMF Inband is selected, the DTMF
		digits are passed through the MultiVOIP
		unit as they are received. In 502c BRI
		software, “DTMF Out of Band” can be
		checked or unchecked.
FAX Parameters
Fax Enable	Y/N	Enables or disables fax capability for a
		particular channel.
Max Baud	2400, 4800,	Set to match baud rate of fax machine
Rate	7200, 9600,	connected to channel (see Fax machine’s
(Fax)	12000,	user manual).
	14400 bps	Default = 14400 bps.
Fax Volume	-18.5 dB	Controls output level of fax tones. To be
(Default =	to –3.5 dB	changed only under the direction of Multi-
-9.5 dB )		Tech’s Technical Support.
Jitter Value	Default =	Defines the inter-arrival packet deviation (in
(Fax)	400 ms	milliseconds) for the fax transmission. A
		higher value will increase the delay,
		allowing a higher percentage of packets to
		be reassembled. A lower value will
		decrease the delay allowing fewer packets to
		be reassembled.
Mode (Fax)	FRF 11;	FRF11 is frame-relay FAX standard using these
	T.38	coders: G.711, G.728, G.729, G.723.1.
	(T.38 not	T.38 is an ITU-T standard for storing and
	currently	forwarding FAXes via email using X.25
	sup-ported)	packets. It uses T.30 fax standards and
		includes special provisions to preclude FAX
		timeouts during IP transmissions.
