Hi Alex,
As background, I believe there is still a bit of resentment and ambiguity from the telecommunications act of 1996, which 'encouraged' ILEC's to open their facilities to CLEC's in an effort to increase competition. One of the sore points was NEBS compliance. The ILEC's insisted that anything that came into their facilities would need to be NEBS level 3, the status quo requirement. However, many CLEC's were not dealing voice and the FCC QOS requirements did not apply. They successfully argued that they should not be required to meet more than NEBS level 1, a level that ensures the equipment will not be a danger to personnel or other co-located equipment. ILEC's created segregated spaces for co-located equipment in an effort to isolate it as much as possible from voice switch gear. As with all NEBS programs, the most important thing you can do is identify your potential customers and ask them what needs to be done. At a minimum, you will need a subset of NEBS 3 as outlined in SR 3580. I say subset because you may well be able to avoid Seismic, illumination, acoustic noise and the like if you have a small shelf unit. You will most assuredly need to meet Class B Radiated and Immunity requirements for the client side box, the lightning requirements in Section 4.6 of GR1089, and 60950 safety requirements. Have a Great Day!

I'm still only 80% certain he meant what he said. This was just a casual conversation. If one end of the cable modem goes into a CO or a co-locator's space I think you're out of luck and NEBS applies, either level 1 or 3 as defined by the various RBOC's, for homes - which I think have to be CPE locations then its the 80% answer I got. Contact me privately and I will give you a name of someone who I think we have a good answer for you. He's well known buy most folks but out of respect to his time I don't want to blast it for everyone's contact fill addition.

Is anyone familiar with compliance requirements needed to meet their requirements? I'm aware they all have specific requirements so I would use Verizon and AT&T as a general reference. These modems are located in a residential environment so I'm curious if they would have to meet any of the NEBS or GR ??? requirements? Any thing else to be aware of in the US other than FCC and UL Safety as applicable? All input is appreciated, Alex _____ Do you Yahoo!?
