Also for clarification, "NEBS Level 3 Plus" means all of GR-1089-CORE and all of GR-63-CORE. Also known as "NEBS Level 3 Plus other criteria" Both terms are borne from SR -3580, although not contained within in it. The confusion arises from the fact that not all the criteria in GR-1089 and GR-63 appear in NEBS Levels 1, 2, and 3 levels of SR-3580. There are several that fall into another category that are basically other miscellaneous criteria. Since each RBOC typically requires evaluations to all the criteria in GR-1089-CORE and GR-63-CORE, not just those in Level 1, 2, and 3, the term "NEBS Level 3 Plus" was used by people around industry to mean "NEBS Level 3 plus other miscellaneous criteria in SR-3580 that are not contained in levels 1, 2, and 3" or "all of GR-1089 and GR-63" But as Dave pointed out be careful. The deviations in test procedures or test labs required by some RBOC's can have a significant influence on whether you comply with a given criteria. So you may be NEBS level 3 Plus with one RBOC and not be NEBS Level 3 Plus with another depending upon how the test was performed or who performed it. Also be aware that some RBOC's and CLEC's accept testing to some of the new ANSI standards that are being developed. For instance the earthquake test was revised in ANSI T1.329-2002 and the Fire test was revised in ANSI T1.319-2002. The materials requirements for fire in GR-63 are from ANSI T1.307 which is up for ballot currently and should be accepted by November. All three of these are base documents for GR-63 earthquake and fire tests. These were not used when GR-63 was revised last April. Since three RBOC's and a couple CLEC's participated in the development and approved these ANSI standards, they tend to let manufacturers use these in place of the outdated GR-63 tests. But make sure you discuss with your customer first as Verizon for instance does not accept the new T1.329 fire standard. There seems to be significant interest to have Telcordia revise GR-63 to address these and other issues, and anyone interested should contact Richard Kluge at Telcordia to express interest that a project be opened to update GR-63 with the newest ANSI documents and fix other issues that labs and manufacturers know exist.

Richard, Verizon does not recognize "NEBS Level 3" as called out in Telcordia/Bellcore SR-3580. They had input into this document, but later regretted it. What Verizon does recognize is their own checklist at www.verizonnebs.com <http://www.verizonnebs.com/> . The confusion comes from the fact that the SR-3580 requirements are scattered throughout Verizon's checklist. At the NEBS 2002 Conference last week, Verizon introduced their latest revision of their checklist. They are trying to incorporate all of the other RBOC's and ATT requirements into this document. I caution everyone to obtain the specific checklists/requirements from each or your potential customers and comply with them. "NEBS Plus" is mentioned in an article I wrote for Evaluation Engineering "What Every Startup Needs to Know About NEBS": http://www.evaluationengineering.com/archive/articles/0502emc.htm <http://www.evaluationengineering.com/archive/articles/0502emc.htm> The intent was to highlight that just meeting "NEBS Level 3" was not enough to get equipment into your customer's central offices. In summary, there is no "NEBS Level 3 Plus" requirement, there are only customer requirements.

I have checked the Verizon web pages, the archives of the emc-pstc, and the word search on the internet, with no luck. Otherwise, I believe this is just another name for the checklist document that Verizon uses and can be downloaded from their website. Thanks in-advance.
