Re: NEBS/ETSI Equivalents for PAC RIM
Joe, You'll want to look at ETS EN 300-386-2 for EMI/C and EN 300-019 for Environmental.

For those who have ventured into these regions with carrier class equipment, has NEBS and ETSI carried enough weight or have some countries/carriers required additional testing. I would also be interested in hearing whether Product Safety and/or EMC certifications are required or are declarations/reports sufficient when product is destined for the central office ONLY. I'll take whatever you have but my primary concern for now is: Japan China Australia/NZ Korea Any and all input, feedback, links, etc. would be greatly appreciated. Thx, Joe * ...OLE_Obj...

Re: NEBS compliance for 100baseT / 1000base T
Muhammad, You should also take a look at the Semtech Line. They offer low-capacitance integrated protection circuits designed specifically to protect 10/100/1000 Base Ethernet from GR1089 intrabuilding surge levels. http://www.semtech.com/products/ go to Protection, go to Telecom Datacom, go to 10/100/1000 ethernet Protection.

The question I had was, for nebs compliance we need to pass power cross and lightening tests. For boards with copper ports (100baseT and 100base T), is it possible to use rj45 connectors with integrated magnetics and still get pass these tests. Has anybody done that - if yes, is it possible to share the method. I believe there are components (e.g. sedactors) one can use, but those are capacitve and might impact the signal integrity. Also, mostly that kind of stuff is used on the line side of the transformer. I am just a little bit hesistant to put in on the secondary side... Any input would be highly appreciated...

Re: Some slightly disturbing interview news ...
This is nothing new.. I found this to be typical interviewing technique at several start-ups that I had interviewed with over the past 3-4 years. The questioning would get extremely detailed, and in my opinion, way too focused (for a first interview). I learned to recognize some tell-tale signs.. for instance, where my most of my responses to specific questions got an immediate reaction like but what if you already tried that and it didn't work? .. what else would you do... and the questioning would proceed way down, into the micro-level on this one problem. It was so blatant at one interview that, after a grueling 2 hours, I finally stood up and said hire me and you'll find out, then walked out. They called me back for a second interview! .. I kindly declined..

Date: Wed, May 15, 2002, 6:45 PM Times are tough all round but there's no need to make things tougher. Here in Silly Valley, things are tough and I have made some attempts to find a few people jobs in my spare time. These are people I know personally. I'm sure I'm not alone in this venture. I'm sure most if not everyone on this list would also help. One headhunter who called me wanted to know if I was just plain nuts or just some sort of a good guy handing a job offer off to someone I knew who was looking. I told him it was none of his business smirk, just make sure to give so-and-so a call. Which they do. Unfortunately, what I have personally experienced in the past (rarely), and what appears to be happening at least with a few of companies currently is the following ... EMC job opening is posted. Resumes are sent. A few candidates are selected for interviews. Most of the interview centers on questions about how to solve some problems that are being experienced by said company. Then there's a decision not to hire anyone. Purchase req for new hires is closed. All candidates are rejected. A few months later, same company goes through the whole thing again. Only this time, there's a different set of questions to problems all being experienced by said company. Both sets of questions involving how-would-you-solve-this type of problems. I'm sure most of you know where I'm going with this. At the end of the day, the company or whoever in the company, has their solution or solutions. I'm not crying about this. My questions are ... Comes with the turf? Are you surprised to hear such a thing? Not surprised? Has is happened to you? Heard that it does happen but rarely and with some other company somewhere else? Happens all the time? Never happens? You gotta be kidden? So that's what that was all about! Thanks. Yea, but whaddaya gonna do about it? Well, if it does happen, so much the better I don't work there ... Etc ...

UL6500
Hello All, I'm in the process of specifying an external Ac to Dc power Adaptor which will be used for one of our products. The transformer is to be mounted inside an abs plastic housing with an Ac supply cord and a Dc output cord. Both cords are permanently fixed. Input voltage will be 120Vac and output will be 12Dc, 8Amps. Our product (Audio of sorts)can be used with a PC to provide audio or be used as home theater audio equipment. UL has identified UL 6500 as the approriate std to evaluate our end product to. UL has also indicated that off the shelf transformers, usually evaluated to UL 1411 (for Xfmrs used in certian types of audio products) won't meet the criteria for UL6500. I've had no luck thus far in locating a power adaptor manufacturer that evaluates to UL6500. Plenty have off the shelf product evaluated UL1411. What I'm trying to do here is start off my product's UL 6500 investigation with a Recognized Component power adaptor. This should make my product evaluation that much easier. If any of you knows of a mfgr that has been thruogh the UL6500 process, or if you have any suggestions as to what Power Adaptor manufacturers have a good reputation in working with you on this type of issue, please contact me via email. Additional comments regarding this issue also welcome. we're all in school, our whole lives through Good Health Good Fortune to YOU, George Sparacino - Sr. Compliance Engineer Boston Acoustics - This message is coming from the emc-pstc discussion list.
