摘要： Methods, systems, and apparatus, for receiving, by an optical line terminal, an upstream communication frame from an optical network terminal, the upstream communication frame including a data packet and a last fragment bit; determining, by the optical line terminal, a fragmentation of the data packet of the upstream communication frame; and processing, by the optical line terminal, the data packet of the upstream communication packet based on the fragmentation of the data packet, including: when the data packet is fragmented, examining a last fragment bit of the upstream communication frame, and storing, in a memory device, the data packet when a state of the last fragment bit indicates that the data packet is not a completion; and when the data packet is not fragmented, transmitting the data packet upstream without storing the data packet in the memory device.

摘要： In a transmitter, first and second sets of discrete multitone (DMT) sub-carrier signals or tones are identified. First and second bit groups of a payload data frame corresponding to the first and second sets of tones are selected. The first bit group is then trellis encoded. The second bit group is not trellis encoded. The first trellis coded tone group and the second bit group are then constellation mapped to produce a DMT symbol for transmission. A receiver may use an estimate of signal-to-noise ratio (SNR) of each tone to determine whether to select the tone for inclusion in the first or second set of tones. The receiver may provide the transmitter with information indicating whether a tone is included the first or second set of tones.

摘要： Optical telecommunications devices, systems, and methods. In some implementations, an optical networking unit (ONU) includes a multi-rate receiver having an operating bandwidth that is selected operationally based on physical layer characteristics of received signals and information received from a MAC. The ONU can also include an upstream laser circuit having an output impedance that differs from a characteristic impedance of a system in which the laser circuit is implemented. The ONU can also include a decision feedback equalizer (DFE) having at least one tap weight that is fixed to facilitate convergence of the DFE when signals received by the DFE would otherwise fail to meet characteristics required for DFE convergence.

摘要： Methods, systems, and apparatus for selective MAC address learning are disclosed. In one aspect, multiple different packets are received by a telecommunications device. The multiple different packets include different source MAC addresses. For each of the multiple different packets, a distribution type is determined. The distribution type is one of a one-to-one distribution type or a one-to-many distribution type. Based on the determined distribution type of the particular packet, a forwarding table of the telecommunications device is selectively updated. When the particular packet has the one-to-many distribution type, a source MAC address that is included in the particular packet is not stored in the forwarding table. When the particular packet has the one-to-one distribution type, the source MAC address that is included in the particular packet is stored in the forwarding table.

摘要： Methods, systems, and apparatus for automatically truncating a hierarchical query response are disclosed. In one aspect, a query for hierarchically arranged data about a telecommunications device is received by the telecommunications device. Creation of a response that includes at least a portion of the requested hierarchically arranged data is initiated. Prior to completing the response, that a response constraint will be exceeded by a completed response is determined. In response to the determination, the response is truncated to include less than all of the requested hierarchically arranged data. Reference data indicating that the response has been truncated is inserted into the truncated response. The truncated response with the reference data is transmitted to a device that submitted the query.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing device firmware. In one aspect, a system includes a file server; a subtending device coupled to the file server, and a telecommunications node coupled to the subtending device. The subtending device can include one or more line cards that connect one or more telecommunications nodes to a network. The telecommunications node receives, from the subtending device, a group name and replaces a wildcard in a firmware filename to derive a first network path of firmware files. The telecommunications node installs the firmware files and subsequently receives an updated group name. The telecommunications node replaces the wildcard with the updated group name to derive an updated path, and obtains different firmware files from the updated path. The firmware installed on the telecommunications node is managed based on the first firmware and the different firmware.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing configurations of telecommunications nodes. In one aspect, a system includes a file server; a subtending device coupled to the file server, and a telecommunications node coupled to the subtending device. The subtending device can include one or more line cards that connect one or more telecommunications nodes to a network. The telecommunications device receives, from the file server and based on provisioning information provided by the subtending device, an auto-config file for the telecommunications node and parses the auto-config file to identify a first filename of a unit-specific configuration file. A wildcard value in the first filename is replaced with a unit-specific identifier, and a unit-specific configuration file is requested from the file server. One or more parameters of the telecommunications node are configured based on a response to the request.

摘要： Methods, systems, and apparatus for selecting frame loss measures are disclosed. In one aspect, a Synthetic Loss Measurement (SLM) report for a given interval for a network managed entity that includes at least two network nodes is received. A Loss Measurement Message (LMM) report for a given interval for the network managed entity is received. For the given interval and from the SLM and LMM reports, a reporting measurement for the network managed entity is selected based, at least in part, on a frame rate of data transmitted over the network managed entity during the given interval or an occurrence of a specified network event during the given interval. Frame loss information for the given interval for the network managed entity based on the selected reporting measurement is reported.
