Richard, In addition to Gherys explanation of the note, there is also the definition itself that inherently excludes certain interfaces by means of the wordings widely dispersed and multi-user. But I agree that adding some more definitions of interfaces would help, also myself.
Clause 6.3: Telecommunications port Point of connection for voice , data and signalling transfers intended to connect widely dispersed systems via such means as direct connection to multi-user telecom networks (e.g. PSTN, ISDN, xDSL, LAN (token ring, ethernet, etc) and similar networks. Note A port generally intended for connection of components of an ITE system under test (e.g. RS232, IEEE standard 1284 (parallel printer), USB, IEEE Std 1394 (fire wire) etc) and used in accordance with its functional specifications ( e.g. for the max. length of cable to be connected to it), is not considered to be a telecommunications/network port under this definition Regards, Kris From: richwo...@tycoint.com [mailto:richwo...@tycoint.com] Sent: donderdag 30 januari 2003 19:32 To: emc-p...@majordomo.ieee.org Subject: EN55022:1998 and telecom ports EN55022:1998 defines telecommunication ports as " Ports which are intended to be connected to telecommunications networks (e.g. public switched telecommunication networks, integrated services digital networks), local area networks (e.g. Ethernet, token ring) and similar networks." Since "similar networks" are included, it would seem that dissimilar networks are excluded. What distinguishes a similar network to a dissimilar network? What are some examples of dissimilar networks that are not included?
