Description Use the t1 shutdown command to shut down a T1 channel.
Use the undo t1 shutdown command to bring up a T1 channel.
By default, T1 channels are enabled.
Disabling a T1 channel disables the serial interfaces formed on it, if there is any.
Example # Shut down T1 channel 1.
<Sysname> system-view
[Sysname] controller cpos 1/0
[Sysname-Cpos1/0] t1 1 shutdown
t1 unframed
Syntax t1 t1-number unframed
undo t1 t1-number unframed
View CPOS interface view
Parameter t1-number: Number of a T1 channel on the CPOS interface, in the range 1 to 84.
Description Use the
t1 unframed command to set a T1 channel on the CPOS interface to
operate in unframed mode.
Use the
undo t1 unframed command to restore the default, that is, channelized
mode.
Like E1 channels, T1 channels on CPOS interfaces support unframed (clear
channel) mode and channelized mode.
■ In unframed mode, a T1 channel can form a 1.544 Mbps serial interface
without timeslot division. This interface is named serial slot/card/t1-number:0.
■ In channelized mode, 24 timeslots of T1 channel can be bound and used as
serial interfaces.
Example # Set T1 channel 3 on interface CPOS 1/0 to operate in unframed mode.
<Sysname> system-view
[Sysname] controller cpos 1/0
[Sysname-Cpos 1/0] t1 3 unframed
