摘要： A system has a current mirror that has an input node and an output node and an avalanche photodiode (APD) coupled to the output node of the current mirror. The system also has a nonlinear voltage-to-current conversion element coupled to the input node of the current mirror that transmits current through the current mirror and the APD. Further, the system has a feedback path coupled between the output node of the current mirror and the voltage-to-current conversion element that senses a voltage across the APD and provides, based on the sensed voltage, an input signal to the voltage-to-current conversion element for controlling the element's output current, and the feedback path is arranged to limit a voltage of the input signal such that the output current is limited thereby preventing damage to the APD.

摘要： A communications system and associated method distributes media in a communications network. A Session Initiation Protocol (SIP) communication session call is established between a caller and a communications server. A message is transmitted from the communications server to the media server that includes Session Description Protocol (SDP) parameters for media provided by the media server. Media is delivered to the caller in a packet format in accordance with the Real Time Transport Protocol (RTP) to reuse the same socket as the source IP and port numbers and update RTP timestamps and sequence numbers. The media is transferred to the caller with minimal jitter buffer flushes and network resource usage.

摘要： Flexibility of handling of multicast information using an Internet Group Management Protocol (IGMP) is improved by overcoming failures to respond to group specific queries. Such failures occur when heterogenous host devices are used on a common network. When a failure to respond to a group specific query is experienced, a general query is used to obtain information that was not provided by the group specific query.

摘要： The present disclosure generally pertains to systems and methods for allocating bonding engines among bonding groups. In one exemplary embodiment, a provision module is configured to allocate bonding engines. When selecting a bonding engine for a new bonding group, the provision module only considers bonding engines residing on access modules that terminate at least one of the communication links of the bonding group. Out of the bonding engines residing on access modules terminating at least one communication link of the bonding group, the provision module selects a bonding engine servicing the least number of external links and assigns the selected bonding engine to the bonding group. The provision module also provisions the access modules terminating the communication links of the bonding group such that the selected bonding engine bonds such communication links during operation.

摘要： Improved digital delay line driver is described. A delay line driver circuit includes elements to drive the delay line in one or multiple locations to provide a dynamic, adjustable slew rate on the output signal. The delay line driver circuit may also include active elements coupled to the transistors of the delay line to deactivate the delay line transistors substantially simultaneously, rather than cascading in series. Shutting off the delay line transistors substantially simultaneously reduces or eliminates crowbar or shoot through current on an edge transition of the output signal.

摘要： A system for embedding metadata in data packets has logic that is configured to insert metadata into a data packet after the payload data and padding, if any. The logic further adjusts the packet's overhead, such as a frame check sequence, to account for the added length of the packet. The packet remains compliant with applicable protocols, such as Ethernet, and can be successfully communicated in accordance with such protocols while carrying the metadata. In this regard, the insertion of the metadata is transparent to protocol stacks such that the metadata data does not cause an error or the protocol stacks to render the packet invalid. In particular, the protocol stacks view the inserted metadata as part of the packet's pad field, and the inserted metadata should not cause any errors in the operation of the protocol stacks or prevent the protocol stacks from processing the packet.

摘要： A telecommunications access module comprises at least one bonding engine that receives packet data and bonds subscriber line pairs together to form a bonding group over which packet fragments are transmitted. A database maintains a list of communications subscriber line pairs that form the bonding group. A processor is configured to determine whether an incoming packet subject to fragmentation is long enough to fragment across multiple subscriber line pairs. If the incoming packet can be fragmented, the processor is configured to calculate a cost function for minimum packet fragment sizes that is proportional to the end-of-fragment arrival time at the far end of each subscriber line pair and calculate remainders of packet fragment length. The packet is fragmented based on the calculated cost function and remainders of any packet fragment lengths and allocated to the subscriber line pairs and transmitted.
