  • Bit density controller
    Patent number: 4967389
    Abstract: A bit density controller is capable of transmitting no more than 15 consecutive 0-bits to be sent serially in a data bit sequence, without a 1-bit, for operating on the AT&T T1 network. The bit density controller includes a state machine having a state index and a substitution device coupled to the state machine. The bit density controller additionally can include a buffer for storing at least one frame of the data bit sequence, a memory for storing overhead bits, and an overhead bit inserter for inserting overhead bits into the data bit sequence.
    Type: Grant
