Table 11-11. H.323, SIP, or UNKNOWN Channel Table Column Descriptions

Table Column	Description
Channel	Channel type, Audio, Video, or Data.
Min User R Factor	The lowest User R-factor calculated during a sampling interval for a
	call.
User R Factor	Voice quality measure expressed as a numeric value between 0 and
	94. The value is calculated by Surveyor. Surveyor uses a formula that
	includes packet loss, jitter, transmission delay, and recency to deter-
	mine the User R-factor.
Max User R Factor	The highest User R-factor calculated during a sampling interval for a
	call.
Min Network R Factor	The lowest Network R-factor calculated during a sampling interval for a
	call.
Network R Factor	Voice quality measure expressed as a numeric value between 0 and
	94. The value is calculated by Surveyor. Surveyor uses a formula that
	includes packet loss, jitter, and transmission delay to determine the
	Network R-factor.
Max Network R Factor	The highest Network R-factor calculated during a sampling interval for
	a call.
Estimated MOS	A conversion of the combined R-factors to a Mean Opinion Score. The
	MOS maps to a purely subjective evaluation of call quality where users
	rate speech samples on a scale of 1 to 5.
Dst Addr	The destination IP address.
Dst Port	The destination UDP port.
Src Addr	The source IP address.
Src Port	The source UDP port.
Sync Source	Synchronization source. Internal number identifying the source.
Packet Count	Packet Count. The value is calculated by Surveyor.
Byte Count	Byte Count. The value is calculated by Surveyor.
Dropped Packets	Packets Dropped. The value is calculated by Surveyor.
Codec	Codec/Decoder type. (DataType in H.245)
Jitter (ms)	Jitter in milliseconds. The value is calculated by Surveyor. Surveyor
	uses the formula described in RFC 1889 to calculate jitter.
Min Jitter (ms)	Minimum Jitter in milliseconds. The value is calculated by Surveyor.
	Surveyor uses the formula described in RFC 1889 to calculate jitter.
