Latest Patents

One of Raymond Paul Dell's key patents is titled "Network based call mute." This invention introduces a telephone feature that can be implemented within a Digital Multiplex Switch (DMS) to mute a telephone handset's voice path at the network level. The DMS utilizes a Digital Tone Multi-Frequency (DTMF) receiver to monitor for a specific sequence of DTMF buttons pressed on the handset, specifically the * button followed by two other digits. Upon detecting this code, the DMS interrupts the transmit path of the handset by opening a switch within the cross-connection switch matrix. This effectively removes any background acoustic noise from the muted handset and eliminates electrical noise along the transmission line. This feature proves particularly beneficial during teleconferencing sessions, where multiple participants may not be contributing to the call but need to listen to the discussion.
