t1 set clock
Syntax t1 t1-number set clock { master | slave }
undo t1 t1-number set clock
View CPOS interface view
Parameter t1-number: Number of a T1 channel on the CPOS, in the range 1 to 84.
Master: Set the clock mode of the T1 channel to master.
slave: Set the clock mode of the T1 channel to slave.
Description Use the
t1 set clock command to configure the clock mode of the T1 channel.
Use the
undo t1 set clock command to restore the default, that is, slave.
T1 channels on the same CPOS physical interface can use different clock modes,
depending on connected devices. For example, when connected to a SONET/SDH
device, a T1 channel should use the slave clock mode, and when directly
connected to another device with fiber-optic, it can use either mode so long as the
mode is different from the one used at the opposite end.
Note that different T1 channels of the same CPOS physical interface are
independent of one another in terms of clock mode.
Example # Set the clock mode of T1 channel 1 to master.
<Sysname> system-view
[Sysname] controller cpos 1/0
[Sysname-Cpos1/0] t1 1 set clock master
t1 set frame-format
Syntax t1 t1-number set frame-format { esf | sf }
undo t1 t1-number set frame-format
View CPOS interface view
Parameter t1-number: Number of a T1 channel on the CPOS interface, in the range 1 to 84.
esf: Sets the T1 channel to use the extended super frame (ESF) format.
sf: Sets the T1 channel to use the super frame (SF) format.
Description Use the
t1 set frame-format command to set the framing format for T1
channel.
