Line Rate	Does not apply when the Line Mode is defined as Auto.
	The DSL line rate (in kbps) available for the SHDSL port:
	• auto—The controller selects the line rate. This is available only in
	2-wire mode.
	• Supported line rates:
	– For 2-wire mode: 192, 256, 320, 384, 448, 512, 576, 640, 704, 768,
	832, 896, 960, 1024, 1088, 1152, 1216, 1280, 1344, 1408, 1472,
	1536, 1600, 1664, 1728, 1792, 1856, 1920, 1984, 2048, 2112, 2176,
	2240, and 2304.
	– For 4-wire mode: 384, 512, 640, 768, 896, 1024, 1152, 1280, 1408,
	1536, 1664, 1792, 1920, 2048, 2176, 2304, 2432, 2560, 2688, 2816,
	2944, 3072, 3200, 3328, 3456, 3584, 3712, 3840, 3968, 4096, 4224,
	4352, 4480, and 4608.
	Note Third-party equipment may use a line rate that includes an additional
	SHDSL overhead of 8 kbps for 2-wire mode or 16 kbps for 4-wire
	mode.
SNR Margin settings
Current	The current signal-to-noise (SNR) ratio on the controller, in decibels (dB).
	Valid values range from -10 to 10 dB.
	This option can create a more stable line by making the line train more than
	current noise margin plus SNR ratio threshold during training time. If any
	external noise is applied that is less than the set SNR margin, the line will be
	stable.
	Note Select disable to disable the current SNR.
Snext	The Self Near-End Crosstalk (SNEXT) signal-to-noise ratio on the
	controller, in decibels. Valid values range from -10 to 10 dB.
	This option can create a more stable line by making the line train more than
	SNEXT threshold during training time. If any external noise is applied that
	is less than the set SNEXT margin, the line will be stable.
	Note Select disable to disable the SNEXT SNR.
