Motorola T1/E1 manual Set clock source loopback, Set clock source recovered

Canopy T1/E1 Multiplexer		September 2004
	T1/E1 Multiplexer FPGA Version 3.4
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.
