#### Release Information

Statement introduced in Junos OS Release 8.5.

Statement introduced in Junos OS Release 12.2 for the ACX Series Universal Metro Routers.

#### Description

Minor alarm error thresholds for T1 CRC errors. When the threshold is exceeded for one second, a defect condition is declared. If the defect condition continues for the monitoring period, an alarm condition is declared.

#### Default

10-second monitoring period for values 1e-3, 5e-4, 1e-4, and 5e-5. The 1e-5 value uses a 50-second monitoring period. The 5e-6 value uses a 100-second monitoring period. The 1e-6 value uses a 500-second monitoring period.

#### Options

1e-3—Error rate expressed as
the number of errors per number of bits. The value 1e-3 is one crc error in 10^{3} bits.

1e-4—Error rate expressed as the number of
errors per number of bits. The value 1e-4 is one crc error
in 10^{4} bits.

1e-5—Error rate expressed as the number of
errors per number of bits. The value 1e-5 is one crc error
in 10^{5} bits.

1e-6—Error rate expressed as the number of
errors per number of bits. The value 1e-5 is one crc error
in 10^{6} bits.

5e-4—Error rate expressed as the number of
errors per number of bits. The value 5e-4 is five crc errors
in 10^{4} bits.

5e-5—Error rate expressed as the number of
errors per number of bits. The value 5e-5 is five crc errors
in 10^{5} bits.

5e-6—Error rate expressed as the number of
errors per number of bits. The value 5e-5 is five crc errors
in 10^{6} bits.

**Default: **5e-6
