Title: Call hold signaling
Inventor: BURG FREDERICK MURRAY
IPC: H04M3/487
Filed: 2003-02-12
Abstract: One or more elements in a telecommunications network ( 10, 10' and 10") receive a call hold-initiating message when a first party places a second party to the call on hold, and in doing so, triggers a call hold event in the network. In response to the call hold-initiating message, the network element may take one or more actions, including releasing one or more network resources and/or providing a service to the second party during the period the call remains on hold. Upon resumption of the call, the network will re-acquire the resources that had been previously released.

Abstract: A system and method for conducting diagnostic services on live electrical equipment, such as electrical power transformers (20) using a tap switch (10 ) installed into each phase of the transformer (20). The tap switch (10) is us ed along with the appropriate test and measurement equipment (60) connected to a test and measurement system (40) to perform the diagnostic service when the transformer (20) is live and in-service. The tap switch(10) allows the diagnostic service to be performed without the hazard of disconnecting the bushing tap(21) in order to connect the bushing tap(21) back to the test and measurement equipment (60). The tap switch (10) provides for live diagnostic tests and measurements for the early identification of potential failures using diagnostic services, such as partial discharge and frequency response. Thus, live diagnostics can be performed on electrical power transformers (20 ) while the transformers (20) are in service using a tap switch (10) resulting in a reduction in down time and thus costs.
