Title: Passive optical network system, device and method for providing biderectional broadcasting service
Inventor: CHOI JEE YON
IPC: H04L12/28
Filed: 2005-12-08
Abstract: A passive optical communication system for supporting a bidirectional broadcasting service, a device thereof, and a method thereof are provided to offer a bidirectional broadcasting service at a low price by installing optical signal circulators at an OLT(Optical Line Terminal) and an ONT(Optical Network Terminal), respectively and transferring both upstream broadcast signals and downstream broadcast signals through a single broadcasting optical wavelength. A passive optical communication system for supporting a bidirectional broadcasting service comprises a plurality of ONTs(640), an optical coupler(630), and an OLT(620). The ONTs(640) convert RF-type upstream broadcast signals and upstream communication data into optical signals, execute wavelength multiplexing for them, and output them. The optical coupler(630) collects wavelength-multiplexed upstream optical signals from the ONTs(640) and transmits them to the OLT(620). The OLT(620) receives the wavelength-multiplexed upstream optical signals from the optical coupler(630), executes wavelength demultiplexing for the received optical signals, and divides them into upstream broadcast signals and upstream communication data.

Abstract: Inhibitors of bone calcium resorption are administered to allow high doses of vitamine D compounds or mimetics to be given the intent of treating non-calcium related diseases such as cancer, psoriasis, and autoimmune disease without the dangers of calcification of kidney, heart, and aorta. Inhibitors of bone calcium resorption include the bis- phosphonates, OPG or the soluble RANKL receptor known as sRANK, and function to block the availabilite of calcium from bone thereby preventing hypercalcemia and the resulting calcification of soft tissues. Thus, high doses of 1alpha,25-dihydroxyvitamin D3 (1,25-(OH) 2D3), its analogs, prodrugs, or mimetics can be utilized with minimal risk to a patient. Specifically, alendronate is shown to block the bone calcium mobilization activity of both 1,25-(OH) 2D3 and its very potent analog, 2-methylene-19-nor(20S)- 1alpha,25 dihydroxyvitamin D3.
