摘要： In a frame synchronous scrambled communications network, communications are protected from pathological bit patterns that may lead to loss of receiver lock by detecting a pathological bit pattern in an incoming traffic stream using a pathological pattern detector. When a pathological bit pattern, such as a transition-less bit pattern, is detected, a corrective bit pattern is generated and inserted or substituted into the incoming traffic stream before transmission to the receiver. The receiver can be configured to revert the modified traffic stream back to the original traffic stream.

摘要： A system and computer readable medium for a burst mode optical receiver that enables an optical receiver to receive signals from a plurality of optical network units at different optical power levels. In an exemplary embodiment, the system may include a memory that stores a received signal strength indication, and a media access controller communicably coupled to the memory. The media access controller receives a received signal strength indication of an upcoming data stream to an optical network unit, and asserts a signal control voltage during a guard time to an optical receiver to optimize reception of incoming data streams of the optical network unit based upon the received signal strength indication received from the upcoming data stream.

摘要： A stack switch for performing pass-through forwarding operations, assigning stack switch identifiers to a plurality of stack switches, temporarily disabling supervision messages exchanged by stack switches, and electing a primary master stack switch is disclosed. In the pass-through mode, the stack switch automatically forwards packets between stack ports independent of their destination address to maintain connectivity between adjacent stack switches while conventional bridging and routing operations are disabled. The sequential identifiers are also preferably assigned in accordance with the sequential position of the various stack switches to better reflect the topology of those switches. The switch is also preferably adapted to temporarily disable the transmission of supervision messages between stack switches to prevent re-assignment of network management functions when switch resources are low. The switch may execute a stack switch identifier numbering scheme based on the time the switch became operational.

摘要： A method and system are provided for enabling packet-based tandem free operation C(FO). In one example, the method includes monitoring packets sent between network elements to identify a TFO request message and a TFO acknowledgement message. A substitute TFO acknowledgement message is sent from an intermediate network element if no TFO acknowledgement message is identified, and both TFO and non-TFO call legs may be established.

摘要： A switch in a data communications network for performing traffic generation in addition to standard switching and routing operations is disclosed. The switch uses a fixed number of test packets retained in a conventional switch buffer to produce one or more infinite packet streams transmitted to a router under test (RUT). The switching device enqueues packets in the priority queues, dequeues the packets from the priority queues, transmits the dequeued packets to the RUT, and re-enqueues a copy of the dequeued packets into the priority queues from which they were dequeued. The enqueued packets and associated pointers to packets are organized into linked lists. By re-writing a copy of each dequeued packet to the tail of a linked list and updating the pointers, the switch produces repeatable streams of test packets. The priority buffers, without the re-write operation, may also be used for conventional egress traffic.

摘要： An assembly, and an associated method, by which to place a telephonic station in virtual residency in a telephonic network. The virtually-resident telephonic station is coupled to a packet data network, such as the Internet backbone. The virtually-resident telephonic station has packet network address determined by the location of its connection to the packet data network. An index, formed by an indexer, is maintained at a proxy server embodied at the packet data network. When a call is placed by a calling station for connection with the virtually-resident telephonic station, the call is routed to the packet data network, and the index is accessed to ascertain the address of the virtually-resident telephonic station. When the address is ascertained, the call is routed to the virtually-resident telephonic station, and the call connection is completed.
