Cisco Systems WS-X6624-FXS specifications Fax and Modem Transport Parameters

Features

Table 2	Fax and Modem Transport Parameters (continued)
Fax payload size		Configures the size of the fax payload (fax data)	20
		carried over real-time transport protocol (RTP). The
		value can range between 20 and 48.
Non standard facilities		Overrides the country code passed by the fax	65535
country code		machine with the value defined. Setting the value to
		default (65535) results in the gateway passing the
		country code values received from the fax machine
		to the far end. If the value is not the default, then the
		gateway will pass the configured value as the
		country code to the far end. It will suppress the
		actual country code passed by the fax machine.
		Country code can be received by the gateway from
		the far end through ISDN. For details about the
		nonstandard facilities country code, refer to the
		T.35 specification.
Non standard facilities		Overrides the vendor/provider code passed by the	65535
vendor code		fax machine with the value defined. Setting the
		value to default (65535) results in the gateway
		passing the vendor code values received from the
		fax machine to the far end. If the value is not the
		default, the gateway passes the configured value as
		the vendor code to the far end. It will suppress the
		actual vendor code passed by the fax machine. The
		vendor code can be received by the gateway from
		the far end through ISDN. For details about the
		nonstandard facilities vendor code, refer to the T.35
		specification.
Fax/Modem Packet		Enables packet redundancy support for fax and	Checkbox unchecked
Redundancy		modem calls. Packet redundancy support results in
		retransmission of packets in case of problems.
		Enabling redundancy can have a negative impact on
		performance.
V.21 Flag Sequence		Specifies the number of V.21 flag sequences that	4
Detection Count		need to be detected in order to determine that an
		incoming fax tone is valid. Increase this value when
		there are line disturbances that require the gateway
		to wait for a longer period of time to confirm a fax
		call.
Port Used for Voice		Optimizes the performance of voice calls. If this	Checkbox checked
Calls		parameter is enabled and the parameters for modem
		and fax calls are disabled, the port is configured to
		accept only voice calls. Enable this parameter only
		if you are certain that a port will handle voice calls
		only.
