Supposedly, 2015 has been a busy year for Enya. However, we do not have any detailed information on what Enya is doing these days.
The National Electrical Contractors Association (NECA) recently published NECA-BICSI-607-2011, Standard for Telecommunications Bonding and Grounding Planning and Installation Methods for Commercial Buildings (ANSI). The new standard was jointly developed between NECA and Building Industry Consulting Service International (BICSI).
The standard on copper twisted pair is IEEE 802.3ab for Cat 5e UTP, or 4D-PAM5; four dimensions using PAM (pulse amplitude modulation) with five voltages, â2 V, â1 V, 0 V, +1 V, and +2 V. While +2 V to â2 V voltage may appear at the pins of the line driver, the voltage on the cable is nominally +1 V, +0.5 V, 0 V, â0.5 V and â1 V.
