  • Switching element for cross-connect equipment for digital bit streams multiplexed by time-division multiplexing digital tributaries with different bit rates
    Patent number: 5265090
    Abstract: A switching element for cross-connect equipment for digital bit streams multiplexed by time-division multiplexing of digital bit streams at different bit rates includes, for each incoming frame transmission medium, a device for extracting from said incoming frames signals constituting multiplexing units to be cross-connected. It further includes for each incoming frame transmission medium a memory for signals constituting multiplexing units to be cross-connected adapted to hold at least N signals where N denotes the repetition period in the incoming frames of the lowest bit rate tributary of the multiplexing hierarchy.
