YEL ALM Note: This LED is not functional on the HSSI line module.

RED ALM	Port status	Red	If the port is configured
			as DTE, the LED lights
			when either the DCE or
			the clock source
			becomes unavailable.
			If the port is configured
			as DCE, the LED lights
			when the DTE becomes
			unavailable.

If the port is configured as DTE, the LE goes out when both the DCE and the clock source are available.

If the port is configured as DCE, the LED goes out when the DTE is available.
