Patent number: 5777996Abstract: An inter-repeater backplane that allows seamless integration of multiple repeaters into a single hub and wherein each repeater may be swapped out without causing the backplane to crash, hang-up or pass error messages. The mixed signal state machines operate in conjunction with the dual analog, digital collision signaling scheme so that repeaters can be removed from the hub without causing the remaining repeaters in the hub to malfunction. Additional drivers or external glue logic are not needed for arbitration because PORTN and PORTM information is embedded within the backplane signals. Thus, the backplane scheme according to the present invention is completely seamless.Type: GrantFiled: October 29, 1996Date of Patent: July 7, 1998Assignee: Level One Communications, Inc.Inventors: David T. Chan, Joseph E. Heideman, Haim Shafir, Stefan M. Wurster, David S. Wong

Patent number: 5742603Abstract: A system consisting of a repeater management function and media access control into a single device. The repeater management functions and the media access control may also be combined with bridging support functions. The repeater management function uses a repeater management interface to control information transferred to an access port and to control repeater functions under direction of access port and monitor repeater function and provide status via access port and to control the bridge support function. The bridge function controls information transferred through a bridge port. The MAC function transfers information between the repeater data port and the MAC port (transmit/receive). The integration of the media access controller and repeater management into a single device is independent of the implementation of any of the ports.Type: GrantFiled: September 14, 1995Date of Patent: April 21, 1998Assignee: Level One Communications, Inc.Inventors: Haim Shafir, Mark T.

Patent number: 5717714Abstract: An inter-repeater backplane employs both analog and digital circuitry to convey state machine information to adjacent repeaters thereby allowing seamless integration of multiple repeaters into a single hub without requiring additional drivers or external glue logic. A data path allows the passage of data between multiple repeaters on the inter-repeater backplane and an inter-repeater backplane enable allows individual repeaters to take control of the inter-repeater backplane data bus. An inter-repeater backplane driver enables external bus drivers which may be required in synchronous systems with large backplanes. An inter-repeater backplane clock is used to synchronize multiple repeaters on the inter-repeater backplane. Only two leads (IRCOL and IRCFS) are used to provide transmit and receive collision information. These two leads in conjunction with IRENA also indicate which repeater is receiving data.Type: GrantFiled: January 30, 1995Date of Patent: February 10, 1998Assignee: Level One Communications, Inc.Inventors: Ralph E.

Patent number: 5671249Abstract: An inter-repeater backplane that may operate in either a synchronous or asynchronous mode for data transmission. The inter-repeater backplane includes a bus of electrical signal conductors coupled between repeaters for communicating electrical signals and data transmission mode detector for determining whether to transmit data synchronously or asynchronously. Data is recovered from a received data packet and is reframed for transmission across the inter-repeater backplane. According to which mode of data transmission is selected, the data is then retimed and transmitted across the backplane. In the synchronous mode of data transmission, the data is synchronized with the system clock. When the asynchronous mode of data transmission is selected, the data is transmitted asynchronously with respect to the system clock. In the asynchronous mode, the recovered data is timed with a clock signal associated with the transmitting repeater.Type: GrantFiled: November 27, 1996Date of Patent: September 23, 1997Assignee: Level One Communications, Inc.Inventors: Ralph E.

Patent number: 5267269Abstract: A data communication system employing predetermined equalized waveforms for transmit equalization is disclosed. Serial NRZ data is received from a network controller and utilized to select from memory its equivalent as predistorted and filtered Manchester encoded data. Predetermined waveforms in memory are representative of the analog waveform produced when predistorted digital Manchester encoded data is passed through a high order transmit filter. Data from memory drives a digital to analog converter (DAC) to reconstruct the waveforms into analog form. A line driver having an integrated single pole low pass filter impresses the equalized waveform on to the transmission line.Type: GrantFiled: September 4, 1991Date of Patent: November 30, 1993Assignee: Level One Communications, Inc.Inventors: Cheng-chung Shih, Haim Shafir, Stefan M.

Patent number: 5249183Abstract: A local area network (LAN) having a 10Base-T media attachment unit (MAU) is disclosed for coupling an attachment unit interface (AUI) to a twisted pair link through an AUI port of the 10Base-T MAU. In addition to meeting or exceeding standards set forth in the proposed supplement (P802.3I/D10) to IEEE standard 802.3 for LANs, the MAU provides an interface between the AUI and a RJ45 (twisted pair) connector which auto-engages when activity is detected on the twisted pair link. Lack of activity on the twisted pair link forces the 10Base-T MAU to isolate its AUI port from the AUI. An Ethernet (coaxial) type MAU commonly connected with the 10Base-T MAU at the AUI may be utilized without manual intervention when the twisted pair link is inactive.Type: GrantFiled: March 14, 1991Date of Patent: September 28, 1993Assignee: Level One Communications, Inc.Inventors: Dave Wong, Haim Shafir, Joe Heideman, Cheng C.
