Techniques for dynamic backhaul bandwidth provisioning are described herein. For example, a method may include determining a potential subscriber user equipment load change, transmitting a backhaul bandwidth change request message based a potential subscriber UE load change, wherein the backhaul bandwidth change request message includes a requested backhaul bandwidth level, receiving a backhaul bandwidth change reply message in response to transmitting the backhaul bandwidth change request message, implementing a subscriber UE load change response corresponding to the potential subscriber UE load change based on receiving the backhaul bandwidth change reply message. Further example methods disclosed may include receiving a backhaul bandwidth change request message, wherein the backhaul bandwidth change request message includes a requested backhaul bandwidth level, calculating an available backhaul bandwidth level corresponding to a backhaul, transmitting a backhaul bandwidth change acknowledgement message when the available backhaul bandwidth level supports the requested backhaul bandwidth level.

Techniques are described for indicating a wavelength at which a network interface device is configured to operate. A first controller circuit may determine a wavelength at which the network interface device is operating. The wavelength at which the network interface device is operating includes at least one of an optical wavelength at which a laser of the network interface device is transmitting optical data or an optical wavelength at which a photodiode of the network interface device is receiving optical data. A second controller circuit may cause the network interface device to output a sensory output that indicates the wavelength at which the network interface device is operating.

ASCENT will provide a robust proof-of-concept of three related high temperature processes; each will lead to a step-change in efficiency of carbon removal in three types of pre-combustion capture, producing the hydrogen needed for highly efficient low-carbon power production. The project brings together five small and medium enterprises preparing to launch these concepts with the support of leading research institutes, universities and industrial partners. The essential feature linking the three technologies is the use of a high temperature solid sorbent for the simultaneous separation of CO2 during conversion of other carbon containing gases (CO and CH4) into H2. Each technology provides a step-change in efficiency because they all separate the CO2 at elevated temperatures (>300C) providing for more efficient heat integration options not available in technologies where the separation occurs at lower temperatures. Each process matches both endothermic and exothermic heat requirements of associated reactions and sorbent regeneration in an integrated in situ approach. The synergies between the three technologies are strong, allowing both multiple interactions between the different work packages and allowing a consistent framework for cross-cutting activities across all the technologies. Each technology will be proven under industrially relevant conditions of pressure and temperature, at a scale that allows the use of industrially relevant materials that can be manufactured at a scale needed for real implementation. This represents a necessary step to be taken for each of the technologies before setting out on the route to future demonstration level activities. ASCENT, Advanced Solid Cycles with Efficient Novel Technologies, addresses the need for original ideas to reduce the energy penalty associated with capturing carbon dioxide during power generation, and create a sustainable market for low carbon emission power with low associated energy penalties

LEILAC, Low Emissions Intensity Lime And Cement, will successfully pilot a breakthrough technology that will enable both Europes cement and lime industries to reduce their emissions dramatically while retaining, or even increasing, international competitiveness. LEILAC will develop, build and operate a 240 tonne per day pilot plant demonstrating Direct Separation calcining technology which will capture over 95% of the process CO2 emissions (which is 60 % of total CO2 emissions) from both industries without significant energy or capital penalty. Direct Separation technology uses indirect heating in which the process CO2 and furnace combustion gases do not mix, resulting in the simple capture of high quality CO2. This innovation requires minimal changes to the conventional processes for cement, replacing the calciner in the Preheater-Calciner Tower. For lime there is no product contamination from the combustion gas. The technology can be used with alternative fuels and other capture technologies to achieve negative CO2 emissions. The project will also enable research into novel building materials with a reduced CO2 footprint, as well the upgrade of low value limestone fines and dust to high value lime applications. The high potential of the project is complemented by high deliverability. The requested grant will secure 8.8m of in-kind funding and support from the LEILAC consortium members, which include world leading engineering, cement, lime and R&D organisations. To accelerate further development, LEILAC will deliver a techno-economic roadmap, and comprehensive knowledge sharing activities including a visitor centre at the pilot site near Brussels. In order to reach the required 80% emissions reductions by 2050, CCS will need to be applied to 85% of European clinker production, and LEILAC is uniquely placed to allow Europe to achieve these targets in a timely, effective and efficient manner.

Techniques are described for identifying a rogue network interface device whose laser is not under control of a controller of the network interface device. The techniques identify the rogue network interface device based on reception of a predefined data pattern in a timeslot that is not reserved for any of the network interface devices without needing to disable upstream data transmission from the network interface devices during their assigned timeslots. The techniques also relate to a network interface device determining whether the network interface device is transmitting optical signals at a wavelength different than the wavelength that the OLT to which the network interface device is associated receives.


A method and system for processing an input fuel gas and steam to produce separate CO_(2 )and output fuel gas streams. The method comprises the steps of using a decarboniser segment for reacting at least a solid sorbent reacts with the fuel gas and steam to remove carbon from the input fuel gas and to produce the output fuel gas stream in an exhaust gas from the decarboniser; using a calciner segment for reacting the solid sorbent from the decarboniser segment therein to release the CO_(2 )into the CO_(2 )gas stream; wherein CO_(2 )partial pressures and temperatures in the decarboniser and calciner segments respectively are controlled such that the temperature in the decarboniser segment is higher than the temperature in the calciner.


In general, techniques are described for provisioning network devices in an Ethernet-based access network. For example, an access node located in an Ethernet-based access network positioned intermediate to a back office network and a customer network may implement the techniques. The access node comprises a control unit that discovers a demarcation point device that terminates the access network of the service provider network at the customer network. The control unit of the access node implements an Ethernet protocol to provide layer two network connectivity between the service provider network and the customer network, authenticates the demarcation point device based on a unique identifier assigned to the demarcation point device and, after successfully authenticating the demarcation point device, provisions the demarcation point device.
