Latest Patents

Bergendahl's latest patents include a digital telephone switch with simultaneous dual PCM format compatibility. This invention discloses a PCM telephone switch that is compatible with both DS-1 and CEPT PCM formats. The switch module performs timeslot switching of individual subchannels between DS-1 and CEPT trunks, which are input through digital group interfaces. Each group interface connects to one or more trunks of serial bit streams of either DS-1 or CEPT format standards. After converting the input serial bit stream to a parallel format, it is used as eight bits of the address bits of data processing ROMs. This allows for the corresponding 8-bit word to be parallel read on a per-channel basis and routed to the appropriate output data processing ROMs. The output data bits of the ROMs are the processed data bits, which are reconverted to serial format for either DS-1 or CEPT standards as required by the output trunk. Additionally, A-law or μ-law decoding and encoding is accomplished independently from input to output channel on a per-channel basis.

Another significant patent involves a digital radiotelephone exchange featuring self-diagnostic individual subchannel loopback. This invention allows for an individual subchannel of an outbound PCM data stream to be substituted for an individual subchannel of an inbound PCM data stream. The removed individual subchannel of the inbound PCM data stream can either be substituted in the outbound PCM data stream or discarded. Line signal bits may also be generated and substituted for the line signal bits of the individual subchannel in the outbound PCM data stream.
