A portable voice communication digital switching device is provided for use with voice communication systems. The switching device is contained in a portable switching device enclosure and has a central control unit that includes communication line interface units and an operator position station with a touch display screen for operator switching control of communication components connected to the switching device.

Disclosed are some implementations of methods and apparatus for managing services within a computer network. In one embodiment, a message interchange network for exchanging application-level messages between services, which are located outside the message interchange network, is provided. At the message interchange network, a plurality of application-level messages, which each specify which one or more receiving services are to receive the each application-level message, are received. Each received application-level message is forward towards the one or more receiving services. Correlation information regarding each application-level message that is received into message interchange network is retained. The application-level messages are sent between pairs of the services, and the retained correlation information for each application-level message pertains to each application-level message and any other application-level messages related to the each application-level message.

Systems and methods of Ethernet path selection in a modular network element including one or more ingress line modules, a plurality of switch modules in a chassis, and one or more egress line modules, wherein the one or more ingress line modules and the one or more egress line modules are located separate from one another and connected to the chassis via cabling. The method includes distributing one or more Ethernet flows from the one or more ingress line modules to the one or more egress line modules via the plurality of switch modules; receiving fabric state information at the one or more ingress line modules from the core chassis out-of-band via the cabling; and, responsive to congestion on a path through the plurality of switch modules, selecting a new path by an ingress line module for an Ethernet flow.

A wireless control device includes a power source, one or more sensors, one or more switches, a wireless transceiver circuit, an antenna connected to the wireless transceiver circuit, and a processor communicably coupled to the power source, the one or more sensors, the one or more switches, and the wireless transceiver circuit. The processor receives a data from the one or more sensors or the one or more switches, determines a pre-defined action associated with the data that identifies one or more external devices and one or more tasks, and transmits one or more control signals via the wireless transceiver circuit and the antenna that instruct the identified external device(s) to perform the identified task(s).
