For example, in one embodiment, a first Local Area Network (LAN) access device is to establish a first LAN; a second LAN access device is to establish a second LAN; a first Wide Area Network (WAN) backhaul connection is to provide the first LAN access device with WAN connectivity; a second WAN backhaul connection is to provide the second LAN access device with WAN connectivity; and a traffic aggregation unit is to form a logically bonded WAN interface over the first WAN backhaul and the second WAN backhaul. In some embodiments an optional traffic de-aggregation unit may be used.

Abstract: A probing signal transmitted on a twisted pair telephone line in a DSL system is reflected and received at a DSL device. An estimate of one of a DSL data transmission signal or DSL synch symbol transmission signal is removed from the received probing signal to recover the reflected probing signal. The recovered reflected probing signal is processed to determine characteristics information of the twisted pair telephone line.

Abstract: Described are systems and methods for jointly optimizing Wide Area Network (WAN) and Local Area Network (LAN) network communications. In one embodiment, a management device communicatively interfaced with a WAN and a LAN includes a collection module to collect LAN information from the LAN and WAN information from the WAN; an analysis module to jointly analyze the collected WAN information and the collected LAN information to identify an operational condition; and an implementation module to initiate a management event responsive to the operational condition being identified. In one embodiment, the management event includes generating and transmitting a diagnostics report responsive to a fault being identified. The management device may further generate and execute instructions to remedy the diagnosed fault.

Abstract: Described are systems and methods for a Digital Subscriber Line (DSL) customer premises equipment (CPE) Management Center (CMC). In one embodiment, the CMC includes a communications interface to receive information from the CPE device regarding operation of the CPE device. The received information is analyzed and a command signal generation module generates a corresponding command signal for transmission to the at least one CPE device to modify the CPE device operation based on the analysis results in a manner which either enhances CPE device performance, for example increasing data rate, or improves line stability, for example reducing CPE error rate.

Abstract: A Digital Subscriber Line (DSL) Management Center (DMC) coupled to a DSL network includes a data collection module that receives information regarding the DSL network from a plurality of sources. An analysis module is coupled to the data collection module to analyze the received information and issue a command for one or more of a plurality of DSL performance enhancement devices to optimize their operation. A command signal generation module is coupled to the analysis module to receive the issued command from the analysis module and generate a corresponding command signal for transmission to one or more of the DSL performance enhancement devices.

Abstract: The certificate revocation lists at access points of a wireless access network can be reduced. In one embodiment, an Internet Service Provider (“ISP”) connected to the wireless access network can receive a subscription request from a user terminal capable of accessing the ISP using the wireless access network. When the ISP assigns a subscription identifier to the user terminal, it also provides a service certificate signed by a certificate authority including the subscription identifier. In addition, the ISP also provides the user terminal one or more session certificates to be used to access the wireless access network, where the session certificates having a shorter validity period than the service certificate.

Abstract: A method and apparatus for increasing the spectral efficiency of communications systems by employing portions of the spectrum, which portions might otherwise be reserved as all or part of guard bands and not utilized (i.e., effectively wasted), for communicating at reduced power levels between devices that are determined to experience relatively high performance (e.g., relatively little path loss, etc.). In a communication system having a first predefined maximum system transmission power level for in-band transmissions, a method is provided for determining that communication performance between a first communication device and a second communication device exceeds a performance threshold. Based on the determination, a first band-edge channel for communication between the first communication device and the second communication device (i.e., transmission from the first device to the second device and/or visa versa) is assigned.

Abstract: A user terminal of a wireless access network can use a digital certificate to authenticate itself to access points of the wireless access network. In one embodiment, the user terminal includes a memory to store an identity certificate signed by a certificate that the user terminal can use for authentication, where the identity certificate being based, at least in part, on hardware included in the user terminal. In one specific embodiment, the identity certificate is tied to the serial number of the user terminal.
