Group, As many of you are aware, EN 300 386-2 is looming on the horizon as the new product-specific EMC standard for telecom network equipment. Currently dow is 30 Sep 2002, but I have heard that this could be moved up to as early as 2000.
Presently, telecom network equipment is typically evaluated to EN55022 class A limits. EN 300 386-2 requires that equipment other than that located in a "telecommunication centre" (defined in ETSI 300 386-1) must meet class B limits for radiated emissions. I am looking for input/interpretation from other telco network equipment manufacturers and/or consultants regarding determination of the appropriate environment characteristic in various scenarios (i.e. when to test to class B). For example, if you have a stand-alone remote switching center/concentrator in its own environmental enclosure, can this be classified as a "minor telco centre" (class A) or must it be considered "outdoor location" (class B)? If the telco operator locates his/her CO in the basement of an office building (not a "dedicated, separate building"), does this then mean (per 386-1 subclause B.3) that this is considered "customer premise" type equipment and therefore must meet class B? Any feedback/thoughts/comments? Regards, Scott Lemon Nortel
