reference line
NOTE: This is the master clock reference for all four T1/E1 lines.
The default setting is T1/E1 Port 1.
The default setting is T1/E1 Port 1.
Enter set master clock reference line [1/2/3/4]
where
[1/2/3/4]
represents T1/E1 ports 1 through 4.
RESULT: The system responds
Clk ref line; [1,2,3,4]
