Parameters
line-number: T1 line number in the range of 1 to 28.
local: Sets the T1 line in internal loopback mode.
remote: Sets the T1 line in external loopback mode.
remote: Sets the T1 line in payload loopback mode.
Usage guidelines
Loopback is intended for test use. Disable loopback in other cases.
If a T1 line encapsulated with PPP is placed in loopback mode, it is normal that the state of the link layer
protocol is reported as down.
Examples
# Enable internal loopback on the first T1 line on interface T3 2/0/0.
<Sysname> system-view
[Sysname] controller t3 2/0/0
[Sysname-T3 2/0/0] t1 1 set loopback local
t1 show
Use t1 show to have a quick look at the line state of the specified T1 line on the CT3 interface.
Syntax
t1 line-number show
Views
CT3 interface view
Default command level
2: System level
Parameters
line-number: T1 line number, in the range of 1 to 28.
show: Displays the physical line state of the specified T1 line.
Examples
# Display line state of T1 line 1 on CT3 interface T3 2/0/0.
<Sysname> system-view
[Sysname] interface t3 2/0/0
[Sysname-T3 2/0/0] t1 1 show
T3 2/0/0 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
