I apologize for resurrecting an old string like this but, I’ve encountered a wide variety of interpretations as to what a Telecom Port is in the context of EN55022 and the required testing. One of the latest interpretations I’m struggling with is where the emphasis is on the first statement in the definition “point of connection for voice, data and signaling transfers intended to interconnect widely-dispersed systems via such means as direct connection to multi-user telecommunications networks”
The device employs multiple RS-232 ports to transfer data to peripheral devices that are dispersed throughout a building which will be accessed by multiple users. This loosely fits the excerpt above and appears to be the justification for their interpretation. The examples of the “widely-dispersed systems” given in the definition are on another scale and would seem to exclude this type of device. Any comments would be welcome.

Peter, I like your conclusion ("Infiniband is not a telecommunication port."), but your justification defeated your conclusion. You stated that "It's akin to an ethernet port." However, CISPR22 clearly identifies "local area networks (e.g. Ethernet, Token Ring, etc.) and similar networks" as a telecommunications/network port in its definition. Therefore, Ethernet is a telecommunications/network port and must be conducted emissions tested. My point is that Infiniband cannot run on long cables (100 foot or more plus infrastructure to go building, campus and worldwide through hubs/switches/routers). Monrad L.
