Abstract: The present invention relates to methods for indicating a bonding configuration mismatch of lines of bonding groups. The methods are performed in different nodes of a communications network. Said method comprises sending a Bonding Configuration Value via one line of the bonding group of lines, said Bonding Configuration Value being unique for said bonding group, and receiving a Bonding Configuration Value via each of the lines of the bonding group. It further comprises checking each received Bonding Configuration Value for diverging values. If a diverging Bonding Configuration Value is identified, an alarm message is generated and sent to Element Manager of the communications network.

Abstract: In one embodiment, the present invention is a method and apparatus for measuring the focus performance of a camera and lens combination. One embodiment of a test target for measuring a focus performance of a camera and lens combination includes a target body, the target body displaying a pattern including: a primary pattern covering a portion of the target body and a secondary pattern superimposed over a portion of the primary pattern, the secondary pattern being aligned along an edge of the target body. The test target also includes a ruler positioned adjacent to the edge of the target body, a ruler positioned adjacent to the edge of the target body, such that the secondary pattern directly abuts a zero line of the ruler.

Abstract: A method of re-configuring connections for a plurality of network access nodes arranged to communicate with a network. The network access nodes connected in a series configuration with only one of the access nodes being connected to the network, the method comprises: connecting a switch node between the network and each of the access nodes using a respective link. Prior to connecting the switch node the method further comprises collecting connection configuration data from the network access nodes connected in series and using at least some of the connection configuration data, and/or data derived from the connection configuration data, to configure the switch node to allow communication between the access nodes and the network via the switch node.
