Yes, they are paired cable interfaces and T&R terminology applies to them from NEBS point of view. I asked this question at Telcordia seminar and got this answer, however some testlabs might have different opinion.

It then defines "telecommunications ports" as "paired-cable interfaces to other equipment in a telecommunications network (such as T and R lead, sleeve leads, E&M leads)." Ethernet interfaces are neither paired-cable interfaces nor fit the descriptions of included leads. -----Original Message----- From: Mitch Gaudyn [mailto:[email protected]] Sent: Thursday, April 06, 2000 10:06 AM To: [email protected] Subject: Lightning tests on Ethernet ports I am interested in finding out what lightning requirements exist on Ethernet ports located on both CO and Network equipment. Also, if anyone has done any testing on these ports, I would be interested in the test methods and results. Thank you. Mitch Gaudyn
