Action

Steps

 

 

 

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

 

 

 

Set master clock

NOTE: This is the master clock reference for all four T1/E1 lines.

reference line

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]

 

 

 

Set backup clock

NOTE: This is the backup clock reference for all four T1/E1 lines. The

reference line

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]

 

 

 

 

Log off

Enter lo.

 

 

RESULT: The system responds goodbye.
