  2. Commutation (telemetry) - Wikipedia

    en.wikipedia.org/wiki/Commutation_(telemetry)

    In telemetry, commutation is a process whereby multiple data streams ("measurands"), possibly with differing data rates, are combined into a single frame-based stream for transmission, before being separated again (decommutated) upon reception; it is a form of time-division multiplexing.

  3. Portal frame - Wikipedia

    en.wikipedia.org/wiki/Portal_frame

    A portal frame steel building under construction. Portal frame is a construction technique where vertical supports are connected to horizontal beams or trusses via fixed joints with designed-in moment-resisting capacity. [1] The result is wide spans and open floors. Portal frame structures can be constructed using a variety of materials and ...

  4. Frame synchronization - Wikipedia

    en.wikipedia.org/wiki/Frame_synchronization

    In telecommunications, frame synchronization or framing is the process by which, while receiving a stream of fixed-length frames, the receiver identifies the frame boundaries, permitting the data bits within the frame to be extracted for decoding or retransmission.

  5. Frame (networking) - Wikipedia

    en.wikipedia.org/wiki/Frame_(networking)

    Frames are the result of the final layer of encapsulation before the data is transmitted over the physical layer. [1] A frame is "the unit of transmission in a link layer protocol, and consists of a link layer header followed by a packet." [2] Each frame is separated from the next by an interframe gap. A frame is a series of bits generally ...

  6. CRC-based framing - Wikipedia

    en.wikipedia.org/wiki/CRC-based_framing

    CRC-based framing is a kind of frame synchronization used in Asynchronous Transfer Mode (ATM) and other similar protocols.. The concept of CRC-based framing was developed by StrataCom, Inc. in order to improve the efficiency of a pre-standard Asynchronous Transfer Mode (ATM) link protocol.

    A GFP client frame can be further classified as either a client data frame or a client management frame. The former is used to transport client data, while the latter is used to transport point-to-point management information like loss of signal, etc. Client management frames can be differentiated from the client data frames based on the ...
