R3303-HP HSR6800 Routers Interface Command Reference

233
Parameters
t1-number: Number of a T1 channel on the CPOS interface, in the range of 1 to 84.
Usage guidelines
Like E1 channels, T1 channels on CPOS interfaces support unframed (clear channel) mode and framed
(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 framed mode, 24 timeslots of a T1 channel can be bound randomly to form serial interfaces.
Examples
# Set T1 channel 3 on interface CPOS 2/0/0 to operate in unframed mode.
