  2. Ethernet over SDH - Wikipedia

    en.wikipedia.org/wiki/Ethernet_over_SDH

    A 10-Mbit/s Ethernet link is often transported over a VC-12-5v which allows the full bandwidth to be carried for all packet sizes. A 100-Mbit/s Ethernet link is often transported over a VC-3-2v which allows the full bandwidth to be carried when smaller packets are used (< 250 bytes) and Ethernet flow control restricts the rate of traffic for ...

  3. EoPoS is a standardized method for transporting native Ethernet frames over a SONET/SDH network, by first mapping into one or more PDH tributaries such as T1, E1, or DS3. The tributaries can then be dropped from a legacy ADM , delivered to the customer premises, and the PDH links resolved back to an Ethernet connection by a piece of equipment ...

  4. Synchronous optical networking - Wikipedia

    en.wikipedia.org/wiki/Synchronous_optical_networking

    SONET/SDH is not a complete communications protocol in itself, but a transport protocol (not a "transport" in the OSI Model sense). Due to SONET/SDH's essential protocol neutrality and transport-oriented features, SONET/SDH was the choice for transporting the fixed length Asynchronous Transfer Mode (ATM) frames also known as cells. It quickly ...

  8. Geometrical Product Specification and Verification - Wikipedia

    en.wikipedia.org/wiki/Geometrical_Product...

    Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.

  9. Pratt & Whitney Canada PW500 - Wikipedia

    en.wikipedia.org/wiki/Pratt_&_Whitney_Canada_PW500

    The PW530 has a single stage fan, driven by a 2-stage LP turbine, supercharging a 2A/1CF axial-centrifugal HP compressor, driven by a single stage HP turbine. Although similar in configuration, the PW535 has a booster stage, mounted on the LP shaft behind the fan, to increase overall pressure ratio and core flow.
