lfa: Sets the loss of frame align (LFA) alarm threshold, which can be level-1, level-2, level-3, and level-4.
• The level-1 keyword specifies generating an LFA alarm when two of four frame alignment bits are
lost.
• The level-2 keyword specifies generating an LFA alarm when two of five frame alignment bits are
lost.
• The level-3 keyword specifies generating an LFA alarm when two of six frame alignment bits are
lost.
• The level-4 keyword applies only to ESF frames. It specifies generating an LFA alarm when errors
are detected in four consecutive ESF frames.
By default, level-1 LFA alarm threshold applies.
los: Sets a loss of signal (LOS) alarm threshold, which can be pulse-detection (for the pulse detection
duration threshold with LOS) and pulse-recovery (for the pulse threshold with LOS).
The threshold of pulse-detection, in units of pulse intervals, is in the range of 16 to 4,096 and defaults to
176.
The threshold of pulse-recovery, is in the range of 1 to 256 and defaults to 22.
If the number of the pulses detected during the total length of the specified pulse detection intervals is
smaller than the pulse-recovery threshold, a LOS alarm occurs. For example, if the two thresholds take
their defaults, a LOS alarm is created if the number of pulses detected within 176 pulse intervals is less
than 22.
Examples
# Set the number of detection intervals to 300 for the pulse detection duration threshold.

ft1 bert
Use ft1 bert to start a BERT test on a T1-F interface.
Use undo ft1 bert to stop the BERT test running on the T1-F interface.
Syntax
ft1 bert pattern { 2^15 | 2^20 } time minutes [ unframed ]
undo ft1 bert
Default
No BERT test is performed.
Views
T1-F interface view
Default command level
2: System level
Parameters
pattern: Sets a bit error rate test (BERT) pattern, which could be 2^15 or 2^20.
2^15: Specifies the length of transmitted BERT pattern, in bits, as two to the fifteenth power.
