The port discovery equipment searches for new ports, and, responsive to finding a new port, automatically discovers a predefined set of one or more attributes of the new port. The controller determines that a client-side port and an edge-side port are a matching pair of ports if discovered sets of attributes of those ports match according to one or more predefined rules. The controller then controls the wavelength switch network to re-route the wavelength channel supporting that matching pair between those ports. | 2014-07-03 |
20140186038 | Multi Directional Multiplexer - Described herein is an optical transmission cross-connect for routing wavelength signals to a bank of directionless transceivers. One embodiment ( | 2014-07-03 |
20140186039 | Dynamic Bandwidth Assignment in Hybrid Access Network with Passive Optical Network and Another Medium - An optical line terminal (OLT) configured to receive transmission requests from a plurality of both network elements (NE) and customer premises equipment (CPE), allocate a timeslot to each NE for transmission on an optical distribution network (ODN), and a timeslot to each CPE for transmission on an electrical distribution network (EDN), wherein each NE intermediates between the OLT and the CPEs. Included is a NE configured to transmit a timeslot to a CPE for transmission on an EDN allocated by an OLT, receive data frames from the CPE during the timeslot, and forward the data frames to the OLT without rescheduling. Also included is a method comprising sending a transmission request to an OLT, receiving a timeslot from the OLT for transmission on an EDN in response, transmitting data frames to a NE during the timeslot, wherein the NE forwards the data frames to the OLT without rescheduling. | 2014-07-03 |
