  • Publication number: 20150220560
    Abstract: A wireless communication device includes a processor and a memory coupled to the processor. The memory includes instructions executable by the processor to perform operations. The operations include receiving a communication request input corresponding to an action to be executed with respect to a data file. The action is executable by the processor when the processor is connected to an external resource. The operations include automatically determining, in response to receiving the communication request input, whether the processor is connected to the external resource. The external resource enables the processor to communication via a wireless wide area network. The method also includes generating delayed action metadata in response to determining that the processor is not connected to the external resource. The delayed action metadata indicates that the requested action is to be executed by the processor when the processor is subsequently coupled to the external resource.

  • Patent number: 9071678
    Abstract: A method of diagnosing a transmission loop in an Internet protocol television (IPTV) network includes configuring the loop as an open loop and performing a single-ended loop test (SELT), configuring the loop as a terminated-loop and performing another SELT, subtracting a trace of the first SELT from a trace of the second SELT, and determining the length of the loop from the result. A service assurance system in an IPTV network includes a test module and a DSLAM coupled to a residential gateway by a transmission loop. The test module operates to determine that a fault condition on the IPTV network is caused by a fault in the loop, direct the DSLAM to perform an open loop SELT and a terminated-loop SELT on the loop, receive the results of the SELTs, and determine a location of a tap on the loop based upon the results.
