In some implementations, a device may receive, via a universal serial bus (USB) interface, configuration information and a supply of power from a network device. The device may receive, via an antenna that is external to the device, a first signal indicating timing information. The device may generate, based on the first signal, a second signal and a third signal, wherein the second signal comprises a one pulse per second signal and the third signal comprises a ten-megahertz signal. The device may provide, to the network device, the second signal and the third signal. The device may receive, via an input port, a clock signal to provide an extended holdover functionality to the network device.

A line card of a set of line cards is configured to be coupled to a set of switch-fabric cards to collectively define at least a portion of an orthogonal cross fabric without a midplane board. The line card has an edge portion, a first side and a second side, opposite the first side. The line card includes a set of first set of connectors and a second set of connectors. The first set of connectors is disposed along the edge portion on the first side of the line card and the second set of connectors is disposed along the edge portion on the second side of the line card.

An apparatus may comprise a board that can mechanically support one or more components of the apparatus. The one or more components may include a processor to process a signal received or provided via the apparatus. The apparatus may comprise one or more sets of contacts via which the processor is to receive or provide the signal. The one or more sets of contacts may be associated with permitting the apparatus to function as a connector. The apparatus may comprise one or more electrical connections that provide connectivity between the processor and the one or more sets of contacts.

Electrical connector with embedded processor

An apparatus may include a printed circuit board, an integrated circuit mounted on a first surface of the printed circuit board, and one or more vias that extend through the printed circuit board from the first surface to a second surface of the printed circuit board to provide electrical connectivity for the integrated circuit. The second surface of the printed circuit board may be opposite the first surface of the printed circuit board. The apparatus may include a pin header that mechanically supports one or more pins that provide electrical connectivity for the integrated circuit. The pin header may be mounted to the second surface of the printed circuit board to mate the one or more pins with the one or more vias to provide electrical connectivity for the integrated circuit.

A portable, self-powered, interface converter for converting between Ethernet over twisted pair cables and Ethernet over optical fiber is described. In one implementation, the device may include a first interface to a power-over-Ethernet connection and a second interface to provide a connection to receive fiber optic cabling. A power-over-Ethernet (PoE) circuit may derive power from the PoE connection and output a corresponding power signal. A transcoder may perform physical layer conversion between Ethernet communications over twisted pair cabling connected to the first interface and Ethernet communications over the fiber optic cabling. The transcoder may be powered by the power signal output by the PoE circuit.

The disclosed apparatus may include (1) an access surface that provides access to ports used to connect devices to a telecommunications network via the line card, (2) a back opposite the access surface, (3) a row of ports arranged along the access surface to house a set of transceivers, and (4) a recessed row of ports arranged along the access surface to house an additional set of transceivers, such that the recessed row of ports is recessed inward toward the back relative to the row of ports. Various other apparatuses, systems, and methods are also disclosed.

Apparatus, system, and method for increasing access to transceivers

A device includes a memory, flow table logic, sampling logic, and a processing unit. The memory is configured to store a flow table that stores, as a number of entries, statistics regarding a number of data flows. The flow table logic is configured to generate records corresponding to data flows for which entries are created in the flow table or removed from the flow table. The sampling logic is configured to select one of the data flows for sampling and sample initial data units for the one of the data flows. The processing unit is configured to receive the records generated by the flow table logic, receive the initial data units sampled by the sampling logic, analyze the initial data units to generate analysis results, correlate the records and the analysis results associated with a same one of the data flows, and store the correlated records and analysis results.

In some embodiments, an equipment unit has a set of visual indicators, a power switch, and a set of compute components. The power switch receives a signal representing a status such that when the status is in a first mode, the power switch provides power to the set of visual indicators and when the status is in a second mode the power switch does not provide power to the set of visual indicators. The compute components are configured to receive power when the power switch does not provide power to the set of visual indicators.
