line-number: T1 line number in the range 1 to 28.

master: Adopts the internal clock as the clock source on the T1 line.

slave: Adopts the line clock as the clock source on the T1 line.

Use the t1 set clock command to configure clock source for a T1 line on the CT3 
interface.

Use the undo t1 set clock command to restore the default, that is, line clock.

When a CT3 interface is working in channelized mode, its T1 lines may use 
separate clocks.

# Use the internal clock as the clock source on the first T1 line on interface T3 2/0.
