Joe Take a look at ETSI ETR 143- Equipment Engineering: Connectors for Test and disconnections points, Display of Alarms.
We wrote a report a few years back and the version then was Oct. 1994. It contains details of alarm LED colours etc. Good luck Matthew Sykes Genesys IBS Ltd Radio & Telecoms Approvals Worldwide PSTN21 Automated Telecom Test System Singleton Court, Wonastow Road Monmouth, NP25 5JA, UK Tel: +44 1600 710300 Fax: +44 1600 710301 www.genesysibs.com -----Original Message----- From: nebs-appro...@world.std.com [mailto:nebs-appro...@world.std.com]On Behalf Of Joe Finlayson Sent: 02 October 2001 22:36 To: 'NEBS Newsgroup'; 'EMC PSTC' Subject: LED Color Assignments Would anyone know of an equivalent (ETSI) requirement for the EU, and possibly rest of world, for the Telcordia requirements in GR-474 for LED color assignments? The EU requirements are most important although any additional information would be helpful. I would appreciate it if your answers could be accompanied by a document number, section, etc. The following is from GR-474: 2.2.3.2 NE Display - Visual Assignments and Meanings R2-36 [36] The colors red, yellow or amber, green, and white, indicating the severity of the trouble, shall be used on the NE's physical control/status display panel to visually represent various alarm levels and status conditions at the NE's equipment location and the OC. (See Section 2.7, Maintenance Person - NE Interface.) R2-37 [37] Color assignments for physical panels shall be as follows: .... a. Red shall indicate a critical or major failure, error, or danger. .... b. Yellow or amber shall indicate a minor failure, caution, warning, or temporary malfunction, or state for which the craftsperson should use caution. .... c. Green shall indicate satisfactory operation, active condition, or completion of a process or procedure. .... d. White shall indicate a neutral condition that implies nothing about the success or failure of system operations.
