Table 3-6. Interpretation of the list measurements report
	Displayed
	Field	Function	Indication
	Test:	3-in-24 stress	The loopback jack test is active
	cpe-loopbac	test pattern
	k-jack
	Synchronize	= Y	The DS1 circuit pack is synchronized to the looped
	d		3-in-24 pattern and is counting the bit errors detected
			in the pattern until the test is ended.
		= N	Retry the test:
			1.	Stop the test (test ds1-loop UUCSS end
				cpe-loopback-jack-test).
			2.	Restart the test (test ds1-loopUUCSS
				cpe-loopback-jack-test-begin)
			3.	Repeat Steps 1 and 2 a maximum of 5 times, as
				necessary.
			If the circuit pack never synchronizes, it is possibly
			due to intermittent connections or a broken wire in a
			receive or transmit wire pair.
Bit Error		Cumulative	0 indicates that there are no wiring problems.
Count		detected	A count that sits at 65535 or continues to increment
		errors
			by several hundred to several thousand errors with
			each subsequent list measurements command
			indicates
			■	Intermittent or corroded connections
			■	Severe crosstalk
			■	Impedance imbalances between the two
				conductors of the receive or the transmit pairs.
			1.	Replace wiring, if necessary.
			2.	Note whether the Extended Super Frame (ESF)
				error and performance counters summaries
				(errored seconds, bursty errored seconds, and so
				forth) also increment. Although these counters are
				not used with the loopback jack test, they do
				increment as errors occur.
