Title: Optical wavelength demultiplexer for a video passive optical network
Inventor: OTA YUSUKE
IPC: H04J14/02
Filed: 1997-01-29
Abstract: In a system where a second signal interferes with the detection of a first signal at an input, in which the second signal is composed of a low frequency component and a portion of the frequency spectrum that is higher than that of the first signal, then both signals are processed to eliminate such interferenceby filtering the second signal to eliminate the portion of the frequency spectrum that is higher than that of the first signal and eliminate the low frequency component of the second signal. Advantageously, such processing is done without affecting any low frequency component of the first signal.

Title: Cross-connect multirate/multicast sdh/sonet rearrangement procedure and cross-connect using same
Inventor: OWEN HENRY WALTER LILLY
IPC: H04B10/291
Filed: 1997-11-07
Abstract: A connection procedure for finding by rearrangement a path for multirate, multicast traffic through an SDH cross-connect with subnetwork connection protection. If no free path for a new payload through the SDH switching hardware is available, the switching procedure looks for a path that is adequate and blocked by the least existing payload capacity. If the hunt is successful, the procedure rearranges the existing connections to make possible a path for the new payload. The procedure does not interrupt the existing connections; thus it is a "hitless" procedure. Connections for existing payloads that must be moved to make way for the new payload are queued and the connection procedure is applied recursively, to each in turn, until the queue is empty.
