Grace,
Yes, Telecom ports is in effect as of August 2007. We upgraded our system
based upon a previous discussion last year that 8 wire ISNs are to be used on
unshielded ports regardless of the number of wires used. We purchased the
TESEQ (formerly Schaffner Test Systems) ISN. I also received in the last month
a flyer on an upgrade to the system to support CAT 6 Wiring when used.

Subject: Telecom Ports Requirements per EU
Dear Members,
Could you please comment the latest requirement on telecom port? Is telecom
port measurement mandatory per EU at this time? Section 5.2 of CISPR 22: 2005
with A1+A2 and EN 55022: 2006 lists limits of conducted common mode
(asymmetric mode) disturbance at telecommunication ports.
China has decided to postpone the telecom port requirement (as of early this
month). BSMI (Taiwan) is discussing this requirement and has not mandated it.
I believe VCCI (Japan) has not mandated it, either.
In addition, if you know any manufacturers and models for ISN for Category 5
and Category 6 Ethernet port, please share with me.
Thank you very much and look forward to your help.
Best regards,
Grace
