Patent number: 6172983Abstract: A network having a number of terminals connected by a hub includes managing data transmission collisions by distinguishing among the terminals following a transmission. In the preferred embodiment, the terminals are arranged in a star configuration and the hub is an Ethernet hub that forwards a data packet from a terminal to all of the remaining terminals. A data packet is stored in memory while it is transmitted to all of the other terminals in the collision domain. If a collision is detected in forwarding the data packet, the transmission is completed to the collision-free terminals, thereby isolating subsequent forwarding of the data packet to the one or more collision-inducing terminals. When a no-carrier condition is sensed, the data packet is retransmitted to the one or more collision-inducing terminals.Type: GrantFiled: March 13, 1997Date of Patent: January 9, 2001Assignee: Siemens Information and Communication Networks, Inc.Inventors: Shmuel Shaffer, David Weiss, Charles Marcus White

Patent number: 6172984Abstract: A device (104) transmitting or receiving low priority data may receive or be directed to transfer higher priority data for transmission. If the incoming data is of sufficiently high priority, the device (104) will interrupt transmission of the outgoing data by generating a signal on the bus (102) indicative of a collision. The receiving device (106) will then back-off. To prevent another device (106, 108) from seizing the bus after the back-off, the device (104) immediately (i.e., before expiration of a single slot time), proceeds with the high priority transmission. Once it is finished, the device (104) may resume its earlier lower priority transmission.Type: GrantFiled: November 21, 1997Date of Patent: January 9, 2001Assignee: Siemens Information and Communication Networks, Inc.Inventors: William Joseph Beyda, Shmuel Shaffer

Patent number: 6167374Abstract: A method and system of processing speech information includes segmenting the speech information based upon detection of logical speech boundaries, such as isolated words, prior to compressing and/or transmitting the speech information. In one embodiment, a continuous stream of voice data is analyzed to detect signal segments containing the characteristics of an isolated word, thereby forming frames of speech information. The frames are data compressed to form packets that are transmitted to a remote site. Preferably, the packets include error checking information. In a receive mode, incoming packets are error checked prior to packet decoding. If transmission errors are detected, repairable packets may be corrected. Non-correctable errors cause generation of notice data that are used to notify a listener of the location of lost speech information. Notice data are also generated if the duration between two arriving packets exceeds a preselected threshold.Type: GrantFiled: February 13, 1997Date of Patent: December 26, 2000Assignee: Siemens Information and Communication Networks, Inc.Inventors: Shmuel Shaffer, Dan Lai, William J.
