Ethernet interfaces are normally connected to twisted pair cat 5 cable that run long distances thoughout a facility just as a DSX-1 or other intra-building interface. As such, Jim Brunssen at Telcordia who is responsible for GR-1089-CORE has stated that Ethernet ports used on network equipment are to be tested just as any telecommunications interface (such as a DSX-1) would be. Jon Curtis (of Curtis Straus) also gave a presentation at NEBS 1999 in Las Vegas stating that 10baseT and 100 baseT ports on network equipment must be tested. I suspect you will also find that all or most of the NRTL's will require these ports to be tested as part of a lightning or power fault evaluation.
Jim Brunssen can be reached at 973-929-2977. John Curtis is the maintainer of this listserver and can also be reached at 978-486-0888. I might also suggest possibly contacting ITS in Lexington, KY at 1-800-788-3061 if further clarification is required.
