Parameters
t1-number: Specifies a T1 channel by its number on a CPOS interface. The value range for this argument
is 1 to 84.
Usage guidelines
Like E1 channels, T1 channels on CPOS interfaces support the unframed (clear channel) mode and the
framed (channelized) mode:
• In unframed mode, a T1 channel can form a 1.544 Mbps serial interface without timeslot division.
This interface is numbered in the format of Serial interface number/channel number:0.
• In framed mode, 24 timeslots of a T1 channel can be bound randomly to form serial interfaces.
Examples
# Set T1 channel 3 on CPOS 2/4/0 to operate in unframed mode.
