The standard GR-1089-CORE is available for purchase in electronic media at http://www.bellcore.com/BC.dynjava?BellcoreHomeHomeGeneralHome If you go into the into the Information Superstore and do a keyword search for GR-1089-CORE you get to the following summary:
Document Number GR-1089 Issue Number 02 Issue Date Dec 1997 Product Type Industry Requirements And Standards (RS) Replaces TA-NWT-001089 Issue02 Component of FR-2063, FR-440, FR-64 ORDERING INFORMATION ABSTRACT: This Generic Requirements (GR) document contains the Electromagnetic Compatibility (EMC) and electrical safety criteria, that in Bellcore's view, are necessary for equipment to perform safely and reliably in the environment of a Telecommunications Service Provider. Components of this product are: GR-1089-CORE The cost is $350 and they accept the major credit cards. As Gary indicated the EMC testing is significant but it also gets into electrical safety requirements. Also as Gary indicated equipment specified to meet this requirement often have to meet the Bellcore NEBS GR-63-CORE requirements. This standard covers such things as Operation Temperature and Humidity, Altitude, Heat Dissipation, Flame Resistance, Fire testing, Use of fire-resistant Material, Smoke Corrosivity, Equipment Shock, Earthquake, Vibration, Contamination. This standard itself is fairly extensive and if your customer is not asking for it I would not worry about it, but you should be aware of it. GR-63-CORE can be found at the Bellcore Site as well. > -----Original Message----- > From: owner-emc-p...@majordomo.ieee.org > [mailto:owner-emc-p...@majordomo.ieee.org]On Behalf Of Gary McInturff > Sent: Tuesday, January 05, 1999 8:00 PM > To: 'Fred Waechter'; emc-pstc > Subject: RE: Bellcore GR1089 > > > You can get the standard through Bell Labs, Global engineering > documents may also have it.
