  • STM switching arrangement
    Patent number: 7630362
    Abstract: An STM telecommunications switch comprising a plurality of parallel data switching planes and a parallel control planes, each plane having an equal number of input ports and output ports and a central switching unit to switch each input port to any output port and wherein the data is switched in octets.

  • Statistical gain using ATM signalling
    Patent number: 5790552
    Abstract: Statistical multiplexing gain is desirable on ATM links, especially on high-cost international links, and is provided where STM traffic is carried as cells on an ATM bearer. The cells have a bit-stream based AAL format including a map for indicating any STM idle channels. The STM idle channels are not transmitted in the cells. Preferably, the format is AAL Type 1 for structured data, and the map is carried using an extension mechanism of that format.

  • ATM switching arrangement
    Patent number: 5703879
    Abstract: An ATM telecommunications switch includes a plurality of parallel data switching planes and a parallel central plane, each plane having an equal number of input ports and output ports and a central switching unit to switch each input port to any output port. The switch further includes a first rotator to connect each input port cyclically to each timeslot of the central switching unit and a second rotator to connect each timeslot of the central switching unit cyclically to each output port.
