  2. EIA-530 - Wikipedia

    en.wikipedia.org/wiki/EIA-530

    Most of the interchange circuits are Category I, with the exception of Local Loopback (pin 18), Remote Loopback (pin 21), and Test Mode (pin 25) being Category II. TIA-530 originally used Category I circuits for what is commonly called "Data Set Ready" (DCE Ready, pins 6 and 22) and "Data Terminal Ready" (DTE Ready, pins 20 and 23).

  3. ANSI/TIA-568 - Wikipedia

    en.wikipedia.org/wiki/ANSI/TIA-568

    Perhaps the most comprehensive known and most discussed feature of ANSI/TIA-568 is the definition of the pin-to-pair assignments, or pinout, between the pins in a connector (a plug or a socket) and the wires in a cable. Pinouts are critical because cables do not function if the pinouts at their two ends aren't correctly matched.

  4. Boundary scan - Wikipedia

    en.wikipedia.org/wiki/Boundary_scan

    The boundary scan architecture provides a means to test interconnects (including clusters of logic, memories, etc.) without using physical test probes; this involves the addition of at least one test cell that is connected to each pin of the device and that can selectively override the functionality of that pin. Each test cell may be programmed ...

  5. Loopback - Wikipedia

    en.wikipedia.org/wiki/Loopback

    This is called a loopback test and can be performed within a modem or transceiver by connecting its output to its own input. A circuit between two points in different locations may be tested by applying a test signal on the circuit in one location, and having the network device at the other location send a signal back through the circuit. If ...

  6. Registered jack - Wikipedia

    en.wikipedia.org/wiki/Registered_jack

    The RJ45S jack is rarely used in telephone applications, and the keyed 8P8C modular plug used for RJ45S mechanically cannot be inserted into an Ethernet port, but a similar plug, the non-keyed 8P8C modular plug – never used for RJ45S – is used in Ethernet networks, and the connector is often, however improperly, referred to as RJ45 in this ...

  7. Attachment Unit Interface - Wikipedia

    en.wikipedia.org/wiki/Attachment_Unit_Interface

    The physical interface consists of a 15-pin D-subminiature connector that links an Ethernet node's physical signaling to the Medium Attachment Unit (MAU), [2] sometimes referred to as a transceiver. An AUI cable can extend up to 50 metres (160 feet), though often the MAU and data terminal equipment 's (DTE) medium access controller (MAC) are ...

  8. GG45 - Wikipedia

    en.wikipedia.org/wiki/GG45

    GG45 (GigaGate 45) and ARJ45 (Augmented RJ45) are two related connectors for Category 7, Category 7 A, and Category 8 telecommunication cabling. The GG45 interface and related implementations are developed and sold by Nexans S.A. , while the ARJ45 interface and related implementations are developed and sold by Bel Fuse Inc.

  9. Network tap - Wikipedia

    en.wikipedia.org/wiki/Network_tap

    Some vendors define TAP as an acronym for test access point or terminal access point; however, those are backronyms. The monitored traffic is sometimes referred to as the pass-through traffic, while the ports that are used for monitoring are the monitor ports. There may also be an aggregation port for full-duplex traffic, wherein the A traffic ...
