Abstract: Aspects of the subject disclosure may include, for example, a method for down-converting a long-range communication signal that is wirelessly received via a first antenna of a communication device to extract a first version of a baseband signal, down-converting a short-range communication signal wirelessly received from a second device via a second antenna of the communication device to extract a second version of the baseband signal from the long-range communication signal that can be received at the second device, which is remote from the communication device, via a second antenna. The first version and second version of the baseband signal can be combined to generate an information signal that can be processed. Other embodiments are disclosed.

Abstract: Embodiments of the present invention are directed to diagnosing problems in a dual stack network supporting Internet Protocol Version Six (IPV6). Inventoried information can be retrieved from an inventory system in response to a problem associated the dual stack network. It can be determined whether a mismatch exists between live customer address information associated with a customer edge router and the inventoried information. A notification can be generated in response to determining whether a mismatch exists. The notification includes information representing a cause of the problem and resolution of the problem.
