(3)This would read X.21 for an X.21 link.

(4)SYNC LOSS and CD LOSS appear on Mux Link screens. They do not appear on X.21 Link screens.

(5)X.21 CONNECT appears on X.21 Link screens. It does not appear on Mux Link screens.

FRAME COUNT	The number of data frames (in
(X100)	hundreds) sent over the link since the
	last reporting interval.
UTILIZATION %	The average percentage of
COMPOSITE	composite bandwidth used for data
	transmission since the last reporting
	interval.
UTILIZATION %	The highest percentage of system
BUFFERS	buffers used since the last reporting
	interval.
EVENT	The number of frames that were
COUNTS (X1)	received in error and for which
RETRANSMITS	retransmission was requested over the
	link since the last reporting interval.
EVENT	The number of line alarms since the
COUNTS (X1)	last reporting interval. A line alarm is
LINE ALARMS	generated whenever the error rate on
	the link is equal to or greater than 1
	bit retransmitted per 1000 bits.

TIME (SECONDS) The number of seconds for system-

IN SYS FLOW wide (global) buffer control on all

CONTROL channels since the last reporting interval. System-wide (global) buffer control occurs when 87 percent of the available buffer space is used.

TIME (SECONDS) Number of seconds that sync loss

IN SYNC LOSS occurred on the link since the last reporting interval.

TIME (SECONDS) Number of seconds that carrier loss

IN CD LOSS occurred on the link since the last reporting interval.

TIME (SECONDS) Usage (in seconds) of the X.21 link IN X.21 CONNECT since the last reporting interval.
