Example # Display line state of T1 line 1 on CT3 interface T3 2/0.

<Sysname> system-view [Sysname] interface t3 2/0 [Sysname-T3 2/0] t1 1 show T3 2/0 CT1 1 is up

Frame-format ESF, clock slave, loopback not set

FDL Performance Report is disabled

Transmitter is sending none

Receiver alarm state is none

Line loop back deactivate code using inband signal last sent BERT state:(stopped, not completed)

Test pattern: 2^11, Status: Not Sync, Sync Detected: 0

Time: 0 minute(s), Time past: 0 minute(s)

Bit errors (since test started): 0 bits

Bits received (since test started): 0 Kbits

Bit errors (since latest sync): 0 bits

Bits received (since latest sync): 0 Kbits

Table 22 Description on the fields of the t1 show command

Field	Description
T3 2/0 CT1 1 is up	The state of T1 line 1 on the CT3 interface: up or down
Frame-format ESF	Framing format of T1: ESF or SF
clock slave	Clock source used by the T1 line: slave for the line clock or
	master for the internal clock
loopback not set	Loopback state or mode: local, remote, payload, or not set.
FDL Performance Report is	Transmission of PPR in the FDL is disabled. You may enable
disabled	that with the t1 set fdl ansi command.
Transmitter is sending RAI	The transmitter of the T1 line is sending RAI signals. When
	the T1 line receives LOS, LOF, or AIS signals, it sends RAI
	signals.
Receiver alarm state	The type of alarm signal that the T1 line can receive: LOS,
	LOF, AIS, or RAI.

Line loop back activate code using inband signal last sent

BERT state

The loopback code sent last time is in-band LLB activation request code.

BERT test state: running, complete, or stopped (not completed)

Test pattern

Status

Sync Detected

Time

Time past

Bit errors (since test started)

Test pattern in use, 2^11 in this example; synchronization state, and the number of detected synchronizations

The duration of the BERT test and the time that has elapsed

Number of bit errors received since the start of the BERT test

Bits received (since test started)	Number of bits received since the start of the BERT test
Bit errors (since latest sync)	Number of bit errors received since the last synchronization
Bits received (since latest sync)	Number of bits received since the last synchronization
