Jerry Darden Vereen, Ronald Howard Diego, Barry Alan Farber: Optical network terminal with low-power sleep logic that substantially extends the life of the battery after the AC main power supply has been lost. Tellabs Petaluma, Mark C Pickering, October 23, 2007: US07287175 (16 worldwide citation)

An optical network terminal includes a sleep logic circuit that assumes responsibility for monitoring off-hook transitions after the AC main power supply has failed for a predetermined period of time. The sleep logic circuit is very low power and, as a result, allows the optical network terminal to ...

Jerry Darden Vereen, Iris Lopez, Raul F Fernandez: Optical network that detects and removes Rogue ONTS. Law Offices Of Mark C Pickering, May 4, 2006: US20060093356-A1

A point-to-multipoint communications network includes an optical line terminal (OLT) and a number of optical network terminals (ONTS) which each detect and remove rogue ONTs from the network. The OLT monitors transmission errors to detect the presence of a rogue ONT, and can determine the identity o ...
