Note	The list of options may vary according to the system configuration. Additional
	options to those shown in the figure above may be included and are listed below.
	Table 5-18. T1 Parameters Link1 Parameters
Parameters	Possible Values	Description
Frame Type		Sets the T1 framing type
	ESF	24 frames per multiframe
	SF	12 frames per multiframe
Line Code	B7ZS	Sets the line coding method used for zero suppression. The zero
	B8ZS	suppression method is used to avoid long strings of '0', because
		these strings do not carry timing information.
	Transparent
Tx Line Mask	0–133 ft / 0 dB	Controls the link transmit signal characteristics.
	133–266 ft	Options depend on whether the link should be configured with
	266–399 ft	CSU.
	399–533 ft	When the link is configured without CSU, the transit signal mask
		is selected according to the transit line length (0-655 ft.), to meet
	533–655 ft
		DSX-1 requirements.
	7.5 dB	When the link is configured with CSU, the transit signal is
	15 dB	attenuated by 7.5, 15, or 22.5 dB.
	22.5 dB
