  • APPC (Advanced Program-to-Program Communication or LU 6.2)

    APPC (Advanced Program-to-Program Communication, sometimes called LU 6.2) is a communication protocol and programming interface standard that operates in the presentation layer and the session layer of the Open Systems Interconnection (OSI) communications model.

  • B

    baseboard management controller (BMC)

    A baseboard management controller (BMC) is a specialized service processor that monitors the physical state of a computer, network server or other hardware device using sensors and communicating with the system administrator through an independent connection... (continued)

  • BYE packet

    A BYE (or Goodbye) packet is a type of Real-Time Transport Control Protocol (RTCP) packet that is sent when a participant in a multicast event leaves the session.

  • C

    call failure rate (CFR)

    The call failure rate (CFR) is the percentage of calls to an ISP or any network provider that fail to get through. The CFR is commonly used as a statistical measure in assessing Internet service providers.

  • carrier-to-noise ratio (CNR or C/N)

    In communications, the carrier-to-noise ratio, often written CNR or C/N, is a measure of the received carrier strength relative to the strength of the received noise.

  • Cisco Certified Internetwork Expert (CCIE certification)

    Cisco Certified Internetwork Expert (CCIE certification) is a series of technical certifications for senior networking professionals who design, build, implement, maintain and troubleshoot complex enterprise networking infrastructures.

  • Constellation

  • CRC-4 (Cyclic Redundancy Check 4)

    CRC-4 (Cyclic Redundancy Check 4) is a form of cyclic redundancy checking (a method of checking for errors in transmitted data) that is used on E-1 trunk lines.

  • crosstalk

    Crosstalk is a disturbance caused by the electric or magnetic fields of one telecommunication signal affecting a signal in an adjacent circuit.

  • cyclic redundancy checking

    Cyclic redundancy checking is a method of checking for errors in data that has been transmitted on a communications link.

  • D

    device relationship management (DRM)

    Device relationship management (DRM) is enterprise software that enables the monitoring, managing, and servicing of intelligent devices over the Internet.

  • F

    fault management

    Fault management is the component of network management concerned with detecting, isolating and resolving problems... (Continued)

  • FCAPS (fault-management, configuration, accounting, performance, and security)

    FCAPS is a network management framework created by the International Organization for Standardization (ISO). FCAPS categorizes the working objectives of network management into five levels. The five levels are:  fault-management (F), the configuration level (C), the accounting level (A), the performance level (P) and the security level (S).

  • FECN/BECN (forward explicit congestion notification/backward explicit congestion notification)

    In a frame relay network, FECN (forward explicit congestion notification) is a header bit transmitted by the source (sending) terminal requesting that the destination (receiving) terminal slow down its requests for data.
