Abstract: A radio frequency (RF) coaxial conductor. The connector includes an outer conductor, an inner conductor, and a dielectric insulator. The outer conductor and the inner conductor are concentrically positioned and insulated by the dielectric insulator. An insertion hole is disposed axially in the interface end of the inner conductor and an elastic element and U-type cylinder are installed in the hole. The outer wall of the U-type cylinder physically contacts the inner wall of the hole to form an electric continuity between the U-type cylinder and the inner conductor. The elastic element installed below the U-type cylinder provides rebounding force on the U-type cylinder when the center conductor of a coaxial cable is inserted and pressed into the U-type cylinder to ensure a good electric continuity between the center conductor and the inner conductor of the RF coaxial connector regardless of the cut length of the cable center conductor.

Title: Switch-based call processing with detection of voice path connection between multiple trunks in external network
Inventor: BRIDGES SYDNEY D
IPC: H04M3/54
Filed: 2004-02-06
Granted: 2008-04-15
Abstract: A private branch exchange (PBX) or other communication system switch is configured to establish connections for at least first and second calls associated with an external endpoint, using respective first and second trunks. Upon detection of a voice path connection between the first and second calls in a network external to the switch, the switch conferences the first and second calls together within the switch and drops at least one of the trunk connections. The switch may detect the voice path connection using an active approach in which a designated signal is generated on one of the first and second trunks and a determination is made as to whether the designated signal is detected on the other trunk. As another example, the switch may detect the voice path connection using a passive approach which involves monitoring the first and second trunks to determine whether they are connected in the external network.
