Re: LED Color Assignments
Joe, Check with the telco people on this but be careful about the specific definitions of the colors of the alarms. They are more technical than what's given. Red Alarm - An active link has been terminated, either a physical disconnect or software disconnect has occurred. Yellow Alarm - link is still active, an error has occurred. Green Alarm - link is active, no errors. White Alarm - link is inactive. IOW, red and yellow alarms both have errors. But, they are different because red means a link is down. - Doug McKean --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

Re: LED Color Assignments
Joe, Get a copy of EN 60073 - 1993, (IEC 73 - 1991) - it is a good reference. BSI publishes it as BS EN 60073. I doubt it is adhered to entirely by most manufacturers these days, but some of us still do. Like most everything in the Compliance world, it is at least open to dogged interpretation discussions, and perhaps individual concessions. UL/EN60950 reference this, so check there for more supporting verbiage (Colours; clause 1.7.8.2).

RE: LED Color Assignments
Joe See IEC/EN60073 for the major colour assignments - and any sector-specific standards (e.g. for medical see IEC/EN60601, or for industrial equipment see EN60204 - but no special requirements for IEC/EN60950). 60073 requirements are very similar to what you quote for the Telecordia spec.
