  • System for the simultaneous operation of a plurality of terminal equipment at a network terminating unit of a broadband network
    Patent number: 4847833
    Abstract: This system comprises a passive bus system which, for the incoming direction (NT.fwdarw.TE), contains a ring-shaped bus, whereby the device connector lines branched off it, have the same signal transit times, and for the outgoing direction (TE-NT) contains a bus line terminated in a low reflection fashion. For the combination of the bit currents flowing from, or respectively to the terminal equipment, a time division multiplex super frame is transmitted with the standard bit rate of 139,264 Mbit/s, which, in both directions, is composed of two 8704 bit frame containing a complete picture line respectively, wherein B bits are contained for the two alternately transmitting ISDN-narrow band channels (B1) and (B2) and bits for the frame synchronization (Rahm-Sync), or respectively segment synchronization (Vor).
