Action Steps
Set backup clock
reference line
NOTE:
This is the optional backup clock reference for all four T1/E1 lines. The
backup clock reference becomes active only when the master clock reference
line is unavailable. The default setting is T1/E1 Port 2.
Enter
set secondary clock reference line [1/2/3/4]
where
[1/2/3/4]
represents T1/E1 ports 1 through 4.
RESULT:
The system responds
Backup clk ref line; [1/2/3/4]
Set timing mode
NOTE:
Timing mode applies to all four E1 lines. Loopback mode loops the T1/E1
Tx clock to the T1/E1 Rx. Recovered mode recovers the T1/E1 clock from the
incoming T1/E1 over Ethernet bit stream (recovers the clock from the far end
T1/E1). The default timing mode is Recovered.
For master clock timing mode, enter
set clock source loopback
RESULT:
The system responds
Clock source is loopback
For slave clock timing mode, enter
set clock source recovered
RESULT:
The system responds
Clock source is recovered
Log off
Enter
lo
.
RESULT:
The system responds
goodbye
