Errored Seconds
The errored seconds count represents the number of
seconds with at least one bit error since the first
synchronization of the test pattern. The seconds prior
to the first pattern synchronization are ignored. This
parameter will count while the bit error count is
greater than zero for any given second and the TSI
interface is declared available until the test is
terminated, or the test mode is changed.
Severely Errored Seconds
The severely errored seconds count represents the
number of available seconds where the bit error rate
-4
was worse than 10 since the first synchronization of
the test pattern. The seconds prior to the first test
pattern synchronization are ignored. This parameter
will count while the TSI interface is available and the
bit error ratio is worse than 10
terminated, or the test mode is changed.
Percent Available Seconds
The percent available seconds count represents the
ratio of the number of available seconds to the elapsed
time since the first pattern synchronization. The
seconds prior to the first test pattern synchronization
are ignored. This pattern will represent the ratio until
the test is terminated, or the test mode is changed.
Percent Unavailable Seconds
The percent unavailable seconds count represents the
ratio of the number of unavailable seconds to the
elapsed time since the first pattern synchronization.
The seconds prior to the first test pattern
synchronization are ignored. This pattern will
represent the ratio until the test is terminated, or the
test mode is changed.
Percent Severely Errored Seconds
The percent severely errored seconds count represents
the ratio of the number of severely errored seconds to
the elapsed time since the first pattern
synchronization. The seconds prior to the first test
pattern synchronization are ignored. This pattern will
represent the ratio until the test is terminated, or the
test mode is changed.
Alarms
The alarm processing on the TSI-MUX is capable of
detecting fault and test alarms. All alarms have an
integration function compliant with ANSI T1.231-
1997. See Appendix A.
The integration function has a criteria to declare time
of 2.5s ± 0.5s of a persistent set condition. The

integration function has a criteria to clear of 10.0s ±
0.5s of a persistent clear condition.
Fault Alarms
Fault alarms describe hardware and software faults
detected by the TSI-MUX card. These alarms are
always displayed and also generate a trap to the system
manager regardless of the service state of the card.
Upon the generation of a fault alarm, the TSI-MUX
card will also change to an Out of Service, Fault state
that will force a protection switch if online and prevent
protection switches if offline.
Test Alarms
Test alarms describe active diagnostic tests. These
alarms are generated when a diagnostic test is
activated and cleared when the test is terminated. The
test alarms cause the TEST LED on the front panel of
the TSI-MUX to be illuminated yellow. The test
alarms will normally not cause traps to the system
management unit since the card must be
Out of Service to initiate a diagnostic test; however,
traps may be generated if the card is placed In Service
while the test is still active.
Performance Parameters
Current Interval
The current interval contains the most recent
performance parameter. This is the same as the first
entry in the 15-minute interval. The data in the current
interval is updated every second and reverts to zero on
a 15-minute boundary.
15-Minute (Quarter Hour) Interval
The 15-minute interval processing contains the latest
96 15-minute performance parameters. The current
15-minute interval is updated every second. Every 15
minutes a new 15-minute performance parameter bin
is created and the previous bins are saved up to a total
of 96 bins. The 96 valid 15-minute performance
parameter data bins contain all of the information for a
24-hour period.
Daily Interval
The daily interval processing contains the latest seven
days of performance parameter values. The current
daily bin is updated every 15 minutes as the 15-minute
interval expires. Every day a new daily performance
parameter bin is created and the previous bins are
saved up to a total of seven bins. The seven valid
daily performance parameter data bins contain all of
the information for a week.
